All-season tires are universal automobile "shoes" with part of the performance properties of winter and. One of the advantages of all-season tires is that you can use one set of tires (with certain restrictions) instead of two, save money and time on tire fitting, and use them all year round. Suitable for driving in the southern regions of the Russian Federation. They are used in climatic zones with a short and little snowy winter, small temperature differences. The disadvantage of all-weather tires is that they lose in grip characteristics to both summer and winter specialized tires. Poorly adapted for use in severe frost and sultry heat.
Marking features
All-season tires, depending on the manufacturer and model, are marked with the abbreviation AS or the inscription All Season, All Weather, Any Weather, Tous Terrain, etc.
As an additional indication of the high performance of the all-purpose rubber in resisting aquaplaning, the word Rain (Aqua) or a small umbrella is applied. Otherwise, the labeling systems for "all-season" and seasonal tires correspond to each other.
However, the presence of one of these designations is not a guarantee that tires are approved for year-round operation. According to the new requirement specified in the Technical Regulations for the countries of the Customs Union, the model of all-season tires must have two certificates of conformity (summer and winter standards).
Distinctive features
1. The unique chemical composition of the rubber compound
Tire manufacturers use special components and additives to obtain average traction on dry summer roads, in winter slush, on slippery road surfaces. The rubber compound is resistant to temperature changes, but is not adapted to operation at very low and high temperatures.
2. Universal tread pattern
Most year-round tires have a summer tread pattern with increased groove area and depth. Designed for mild European winters. Well adapted to dry weather operation on high quality roads. Produced by Pirelli and Goodyear.
There are also tires with a tread in the form of a "spider web" with numerous slots. These all season tires are manufactured by Hankook.
Another version of the tread design is an asymmetric pattern with different inner and outer sides. The former is designed for efficient wet traction, while the latter is designed for precise handling and reliable dry traction.
All-season tires with a more aggressive V-shaped tread pattern perform best in wet weather (summer and winter).
About All Terrain tires
It is mistakenly believed that universal tires with the A / T marking are all-weather, suitable for summer and winter use. In fact, this is a special subclass of tires designed for different road surfaces.
The All Terrain tread is characterized by the presence of large checkers, between which a large amount of free space is provided (for quick and efficient removal of dirt).
Video: All season tires
Universal all-terrain tires are used on asphalt roads in the city, rural gravel roads. Suitable for driving on light off-road, small muddy and swampy areas. Not designed for winter use.
Advantages
- saving free time on tire fitting in the off-season;
- buying one set of tires instead of two;
- acceptable performance characteristics with infrequent use of the vehicle in winter (mainly in urban areas).
Flaws
- insufficiently good grip on snowy and icy roads in severe frost;
- not recommended for use on rear-wheel drive vehicles;
- because of the versatility, the level of grip, reliability of control and braking performance in different weather conditions suffer. They lose in grip and braking properties to both high-quality summer and winter tires.

Overview of three good all-season models
Tires from an Italian manufacturer for the North American market. They belong to the HP (High Performance) class. Guaranteed mileage - 110,000 km. Suitable for operation in the southern regions of the Russian Federation. They have an asymmetric tread pattern.
The best all-season tires developed on the basis of the unique IDP methodology, including virtual mathematical modeling. Increased attention has been paid to rolling resistance characteristics and high traction in warm, dry weather. Provide cars BMW 3 Series, Audi A3, Mercedes C-Class and others with precise controllability at high speeds, excellent braking performance.
Poorly adapted to deep snow and slippery road surfaces (especially in the presence of ice on the roads).
2. Michelin LTX M/S2
One of the best all season tires for SUVs, pickups and light trucks. They have a new composition of the rubber compound. Special attention has been paid by Michelin to the addition of a large amount of high quality silica to achieve balanced performance.
Endowed with an efficient drainage system due to 4 deep grooves. Increase resistance to hydroplaning, increase the level of grip on wet roads.
The tires have a solid carcass system based on a 3-ply breaker. This helps to increase the load capacity, increase the strength characteristics and extend the life of the tires.
The LTX M/S2 is capable of cross-country driving, but does not perform well in serious off-road conditions.
Belongs to the class of all-season touring tires. An attractive model in terms of price-quality ratio, developed by a subsidiary of the giant tire concern Continental. Provides a fairly high level of comfort when driving on good smooth roads. Differs in the balanced coupling characteristics. The factory warranty for wear resistance of the tread is 120 thousand km.
It has an S-shaped symmetrical pattern. The tread has 5 longitudinal ribs, one of which is located in the center. Thanks to him, the tires have excellent directional stability.
Should I buy all season tires?
"All seasons" - tires for mild European winters, high-quality asphalt roads that are constantly cleaned. They differ in balanced characteristics, but frankly give in under adverse weather conditions (hard frost, prolonged precipitation, great heat).
Thus, buying all-season tires is not the right choice for most Russians. It is much better to buy winter tires (for example, Velcro for urban use or spikes for frequent country trips) and separate summer tires for your driving style.
All-weather tires show the best qualities in regions where the difference between summer and winter is not so significant, in not very cold weather. Otherwise, it does not provide the necessary level of safety when driving, especially on ice and in deep snow.
The car market quickly responds to requests from motorists. That is why the concept of universal all-season tires was developed, which are suitable for any season. The result is a symbiosis of summer and winter tires, which has the characteristics of both types. However, it was not possible to embody all the advantages without disadvantages.
It is possible to better understand the specifics of all-season tires only after a certain analysis of seasonal tires.
- For the manufacture of the summer version, hard rubber is used. Low wide tread with various types of pattern prevents premature wear of the tire and provides the necessary coefficient of adhesion of rubber to the road surface. A high tread will significantly increase the mass, which means it will reduce the contact area. It is recommended to use this type of rubber at a temperature not lower than +7 °C. Otherwise, the material becomes stiffer, wear increases, the risk of tire damage and accidents increase.
- Winter tires are made from softer rubber. The softness of the material provides better grip on wet or slippery surfaces. Soft elastic material perfectly tolerates low temperatures, does not tan. On winter tires, tread patterns are applied more deeply, Velcro is also applied - a small zigzag tread pattern - or spikes (read about which is better -). In warm weather, the use of winter tires complicates driving, increases fuel consumption, and the tire wears out faster.
- All-weather tires are made of elastic rubber of medium hardness. In terms of hardness, this type of rubber occupies an intermediate position between soft winter and hard summer. The tread is relatively low, the pattern is applied wider and deeper than in summer, but not as deep as in winter. The number of spines has been reduced and they are much smaller. The size of Velcro is also reduced, they have light adhesive properties. The optimum temperature range for these tires is +5 to -10°C. Use in other temperature conditions reduces tire performance.

Main advantages and disadvantages
Comparative characteristics of advantages and disadvantages will help to evaluate all-season tires. First of all, you don't need to buy two sets of tires. In addition, the cost of all-weather tires is much less than winter tires. The price is about the same as the summer one.
Benefits of all season tires
The main advantages of "all-weather" are the following nuances.
- No need for seasonal change.
- No need to change tires often and worry about where to store them (read about). Owners are only required to monitor the balance and condition of the rubber.
- Efficiency in changing winter conditions.
- In the conditions of the middle and southern lanes, when snow replaces rain in winter, combined tires with a low tread and elastic tires noticeably win.
- Low noise.
- On the asphalt road surface, they practically do not make noise and “go easily”.
Important disadvantages
Of course, you should think carefully about whether the pros outweigh the serious cons of this type of tire. Such tires have a number of disadvantages.
- Continuous wear.
- The operation of rubber year-round, in any weather, significantly reduces the shelf life. In summer, elastic rubber can melt under high temperatures. In this regard, Velcro and spikes deteriorate and fly off. In hot summers or harsh winters, these tires last for 6-7 months.
- Ineffective in mid-winter conditions.
- For winter in most regions of Russia, this type of rubber does not fit well: insufficient softness and elasticity cannot provide the proper level of adhesion to the surface. Small spikes and Velcro have less grip. Insufficiently soft rubber for a harsh winter dubeet, crack and can scatter right in the process of movement.
- Not designed for aggressive driving.
- Professional drivers compare all-season tires to the effect of a "bald tire" when driving aggressively. Textured details make it difficult to move off-road. Only new all-weather shoes will help you get out of the liquid mud.
- Increased risk of loss of control in extreme weather conditions.
- The poor maneuverability of the car on all-season tires complicates its management. They cannot cope with heavy snow or ice. There is also a high risk of tire damage right on the road.
Another important nuance that you should pay attention to when buying is this. What do they mean, our specialist will tell.
Motorists of the post-Soviet space, probably the best on the European continent, have studied the behavior of all-season tires from their own experience. The domestic tire manufacturer does not indulge in diversity and grip with the road surface in winter. However, modern world-class technologies that have begun to be massively used in Russian tires have significantly corrected the situation.
One of the brightest representatives on the Russian market among automotive rubber is KAMA-234. In addition to low price, order 2 - 2.5 thousand rubles , this tire has good performance both in summer and in winter. In moderate frost, it does not tan, the tread does not wear out quickly, it is quite possible to drive on such tires for several years, without fear for your own safety on the road.
However, really reliable and high-quality tires are much more expensive and are produced only abroad. It was about these tires that the German magazine AutoBild wrote, which tested 25 all-season tires and chose the top 10 best tires among them based on the results of the tests.
The selected models have excellent properties in a wide range of weather, and experts advise you to definitely pay attention to them when choosing tires for use all year round.
It is worth noting that the use of "all seasons" is justified in moderate climatic conditions, their use, due to the technical subtleties of such rubber, is unacceptable at extremely high or low temperature conditions. In real life, even expensive tires of this kind remain a compromise option, designed more to obtain economic benefits for the owner.
We also recall that engineers developing such tires have to combine mutually exclusive indicators: the tire must have drainage grooves, while the rubber must be soft enough not to turn into plastic at temperatures below 0 degrees and conditional sipes that should help improve grip on slippery surface.
European manufacturers have achieved the greatest success in combining incompatible indicators. In 2016, Michelin offered its advanced version of tires for any season, then Continental took over the baton, hoping to divide the promising market in two.
As noted in the German edition, this queen move was not easy for the tire manufacturer from Hannover. For a long time, Continental resisted the unification of tires and there were natural reasons for that. It was too risky for reputation to launch such a product from one of the largest tire companies in the world, in case of failure, Continental could be in big trouble.
Since the dispute in the manual about whether or not tires are in production is settled in favor of the former, it is safe to assume that modern technology has reached a point where European winters in Germany cannot prevent drivers from feeling safe. In the spring of 2017, the Continental AllSeasonContact model went into production.
As they write in the German edition: the advantages of a year-round tire are obvious to motorists:
1. Eliminates the need for seasonal tire changes. The cost of tire fitting saves a decent car owner's budget. In Russian realities, this is about 5 - 7 thousand rubles.
2. There is also no need to clutter up balconies or store tires in special warehouses.
On our own, we add another important plus: the wear of the edges of the rims is also minimized, because not every tire service has new equipment that does not cripple the rims.
Conclusion on the use of "all-weather": saving money and time. An obvious plus!
The task set during testing: determine whether the comfort of use is at odds with the main indicator of tires - safety. To do this, extensive tests were carried out on 25 tires in the snowy Alps.
Of the 25 applicants, 10 tires passed the second round of testing.
What's wrong with 15 all-season wheels bought in retail stores? According to tests, they had excessively high braking distances in wet weather.
For a comprehensive study of the behavior of the remaining ten wheels, each set of tires was driven over 10,000 km on dry summer roads and slushy winter roads. As a result of the final round, a table was compiled with the indicators of the Top 10 tires.

Every car owner once heard such a phrase as all season tires or, more simply, "all-weather". Probably, many people wondered what all-weather season is and why then seasonal tires are needed, if you can change your shoes once and no longer "steam" about this. Today we will try to give answers to these and many other questions in order to make it easier for you to make the right choice.
To begin with, let's understand what are all season tires? Those who immediately chuckled and replied that these are universal tires that are equally good for both winter and summer are wrong! In fact, all-season tires are tires that have satisfactory characteristics for both summer and winter use. I draw your attention to the fact that it is satisfactory, and not ideal or excellent.
What parameters determine tire performance?
Tires are distinguished by the following parameters:
- Rubber composition;
- Tread Height;
- Tread pattern.
For winter tires the tread is high, which allows them to provide better grip on the road, such tires crush snow better and are more disposed to the subsequent self-cleaning of the tread from snow. Winter tires have a tread that consists of sipe blocks, which in turn are divided into even smaller sipes. The main advantage of winter tires is their elasticity, which they retain even at low temperatures due to the special composition of the rubber.
With summer tires the tread is lower, for this type of tire the main thing is to ensure reliable grip of the wheels with asphalt. Grip provides a special pattern that is applied to the tires during their manufacture. The pattern of summer tires differs from that of winter tires, for example, for summer tires, the depth and width of the grooves that separate the tread blocks are small. There are also modifications of summer tires, the so-called "rain" tires. The tread of these was created specially optimized for the fastest possible withdrawal of water that enters the tread recesses. Most often, rain tires have a longitudinal groove that runs along the entire surface of the tire, thanks to the recesses made at an angle, water is quickly thrown out of their tires to the side. Summer tires are made from harder materials, this is done taking into account the fact that in the heat the asphalt heats up and too soft rubber cannot provide the required rigidity, as a result of which the car may lose control.
This is a kind of compromise between summer and winter tires, that is, in winter they are slightly better than summer tires and slightly worse than winter tires, and vice versa in summer. In fact, an all-weather tire is a tire well adapted to winter and summer, the tread of all-weather tires is lower compared to winter tires, however, the tread blocks are cut into lamellas and separated from each other, just like on winter tires. Some motorists hypothesize that all-season tires were invented for warm countries where they are a rarity. In principle, they are partly right, all-weather can and even probably should be used where the temperature does not drop very low or, for example, in those countries where it is very warm during the day and slightly frosty at night. Having installed, for example, winter tires in this climate, during the day it will be subject to a lot of wear and vice versa, if you change into "summer" shoes, then at night or late in the evening summer tires can let you down at the most unpleasant moment, at some turn ... Therefore choosing a compromise called all-season, drivers living in such a climate save money and protect their health.
As for us, Russian motorists, I would strongly not recommend using all-weather tires all year round. Our winters are cold and simple, slightly optimized tires, they simply “will not work” with us, as a result, the desire to save time and money can result in big expenses for repairs and treatment, I think the hint is clear, there is no need to explain...!?
Although, on the other hand, Russia is large and covers several climatic zones, so you should listen to car tire manufacturers, and they advise choosing tires based on the climate and average air temperature in winter and summer. It is wrong to categorically deny the existence of all-season tires and claim that they are absolutely useless and not good for anything. Like any product, all-season tires have their pros and cons, I propose to consider them as a brief summary.
All season pros:
- These tires are cheaper than winter and summer tires combined;
- You save on the need to "change shoes" twice a year;
- If the winter turns out to be abnormally warm, the all-season will help you out well, they are not afraid of a little snow, and they feel good on the pavement. In addition, they are not as noisy while driving as the vast majority of winter tires.
Cons of all-season tires:
- On ice, all-season tires are inferior to winter tires on packed snow;
- All season wears out twice as fast due to the fact that it is used all year round;
- The elasticity of all-season tires is much lower compared to winter tires, so in severe frost (below -10 °) they can become hard, as a result, the car will slide at the slightest skid. Same in summer, if it's too hot, too soft will cause the tires to lose traction.
When buying an all-season, you need to understand that these are ordinary tires that “fit tightly” into the concept of “almost winter” or “almost summer”, these are tires not for racing or off-road, which means that you need to ride on such tires accordingly.
And now that you know about all the positive and negative aspects of the "all-season" and "season", answer yourself the question you asked at the beginning of this article: Which is better - all season or winter tires? Everyone will have their own answer to this question, and for each it will be correct in its own way. It is important to understand that all-season tires are worse than purely summer or purely winter ones, so, of course, all-season tires will never be able to become a full-fledged replacement for one or another. All-season tires are designed for those who live in warm climates, rarely leave the garage, do not have "extra" money for an additional set of tires and at the same time do not like high speeds, if you are just such a person, then feel free to buy an all-season. For everyone else, I would highly recommend buy two sets of tires and change it depending on the season, it may be more expensive, but in any case it is much calmer and safer.
Oddly enough, but the situation of an overabundance of the market with competitive goods complicates the choice. The consumer thinks for a long time what to buy, as if not to miscalculate. And beforehand, people read the annotations to the product, view the advertisement, discuss the rating of r15 tires, save money for rubber. Undoubtedly, a large number of tires are presented in the assortment, each model can be characterized on the positive side and identify disadvantages. In the process of comparison, consumers determine what advantages this or that product has, how much they agree to put up with its negative characteristics. This is how the rating of all-season tires is formed and presented to motorists.
All season tires
So what to buy, what you need to pay attention to?
If you want to buy all-season tires, then consider the following rubber models:
Tires Goodyear Vector 4 Seasons
The tire is all-season, suitable for cars and SUVs. The usual diameter is from 13 to 18 inches. The product has a special tread made using SmartTred technology, which is responsible for a strong grip even with ice and snow. In the center of the figure, a V-shaped element is visible, which is responsible for directional stability and forms an anti-snow wedge. And along the edges there are deep grooves, they are responsible for reducing the effect of aquaplaning. There are also self-closing 3D slats, they are responsible for the braking distance, and it doesn’t matter what season the car is operated in.
Goodyear Vector 4 Seasons When the car is driving on a dry road surface, the tire touches the asphalt across the entire width of the profile. The tread design itself redistributes the load on the existing three-dimensional sipes.
Goodyear Vector 4 Seasons tires can "decipher" weather conditions, that is, understand how to work in situations of high summer temperatures, snow drifts in winter or during the first autumn frosts. The fact is that the tires are made using Weather Reactive Technology, so the tire reacts to changes in weather conditions, provides the necessary maneuverability of the car, and withstands road loads.
Goodyear Vector 4 Seasons Thus, Goodyear Vector 4 Seasons, created for cars and SUVs, are distinguished by quality, a unique tread that can ensure the safety of movement in both summer and winter. No wonder the Goodyear Vector 4 Seasons is included in the rating of all-season tires, because they are also known for their environmental friendliness. Tires are made from materials that can be safely recycled.
Benefits of Goodyear Vector 4 Seasons tires
- Long life, no frequent tire changes
- Low wear
- The braking distance does not deviate from the designated norms
- Road grip is good at any time of the year
- Fuel economy
- Reduced hydroplaning effect
- Driving comfort
- Average price - 3000 rubles
Tires Cooper Discoverer A/T3
Tires are included in the r15 tire rating, although tires for SUVs can also be selected from the list of product sizes. In general, the diameter range varies from 15 to 18 inches. American manufacturers decided to combine many modern advantages in rubber that would ensure safety on the road both in summer and in winter. Tread brand A/T3 ( All Terrain) means that the product belongs to the mud tires capable of providing car movement not only in an urban environment, but also off-road. Looking closely at the picture, you will see a broken rib in the center, which provides traction in the winter, especially in slush. And the zigzags protect the powerful tire from rocks when the machine is used off-road.
Cooper Discoverer A/T3 An important difference between tires Cooper Discoverer A / T3 - a strong sidewall. It will not be damaged if you regularly make trips to dirt roads, forest clearings. The strength of the product is due to the selected material. Since 2016, the Cooper company has been manufacturing tires for SUVs and pickup trucks from a special rubber compound. One of its ingredients is silicon dioxide, in Latin it is silica. Silica is needed to ensure normal grip with the road surface in winter, when the surface is wet, snowy, icy. The fact is that silica has proven itself well at low temperatures, because the polymeric materials containing it do not lose their properties when the mercury column of the thermometer drops below zero.
Cooper Discoverer A/T3 Thus, the rating of all-season tires for passenger cars and SUVs includes the Cooper Discoverer A/T3, which is distinguished by American quality and a demonstration of innovations in terms of rubber composition. The tires are wear-resistant, cut and puncture resistant, so off-road driving is possible without problems. The product is new - 2016 release. Let's define its emerging advantages.
Advantages of Cooper Discoverer A/T3
Gives good grip on asphalt and off-road
Mud tires suitable for 60% off-road
Provides maneuverability on wet pavement
Not attributed to hydroplaning effect
Low rolling resistance
Car runs quiet with Cooper Discoverer A/T3 tires
Proper traction even on packed snow
The product line includes many standard sizes, which does not limit the choice
