Checking the condition of wheels and tires Renault Sandero, Stepway
For traffic safety and extending the life of tires, it is necessary to visually check them before driving, maintain the required pressure in them, regularly (at least once a month) check it and bring it to normal.
The recommended tire pressures are indicated on the label affixed to the end of the left front door. The plate shows the tire pressures for the front and rear tires for off-road and motorway driving.

It is also necessary to check the tire pressure when the ambient temperature drops or rises significantly and before driving a long distance.
When driving for a long time, especially on high speed, the tires heat up and the pressure in them increases. Therefore, air pressure should be checked with cold tires before driving.
If it is not possible to measure the pressure on cold tires, it is necessary to take into account the increase in air pressure in the tires from heating by 0.2–0.3 bar.

If the pressure is higher than required...
pressure gauge (or a suitable tool) on the valve spool, let the air out of the tire in small portions and check the pressure.
When operating a vehicle with a full load and a trailer, the tire pressure must be increased by 0.2 bar.
Tires must be free of bulges, tread separation and damage that exposes the cord. Residual height tire tread must be at least 1.6 mm.
Tire wear can be measured...
… by measuring the remaining tread depth with a caliper depth gauge.
Tires are not allowed different models on one axle, as well as tires that do not match in size technical requirements car manufacturer.
The manufacturer does not recommend changing wheels. If the tire treads of the front wheels are worn to the limit (wearing out approximately twice as fast as the rear ones), we recommend purchasing one wheel of the same model and putting it on the front axle together with a spare (not worn) wheel. We recommend replacing the least worn wheel (out of the replaced ones) in place of the spare wheel.
Regularly check the tightening of the wheel bolts and, if necessary, tighten the bolts.
If vibrations occur while driving on a flat stretch of road in a limited speed range, the wheels must be balanced by a tire shop. Vibration at all speeds can be caused by patchy tire wear, blistering or other damage, or deformation. rim. Damaged tires or disks are replaced.
Wheel rims should be kept clean to prevent corrosion. Places with a damaged coating can be cleaned with sandpaper, degreased, primed and painted.

Tire pressure should be checked weekly. Maximum fuel economy and tire life are achieved if the recommended pressure is maintained. The pressure should be measured before the start of the movement, because. it changes by 0.2-0.3 bar due to heating.
The labels show the air pressure in the front and rear tires. rear wheels on roads with different surfaces.

When checking the pressure, do not neglect the spare wheel. When checking the pressure, check the tires for cuts, impact marks, and other damage. Check tightness of nipples, replace damaged caps. Check for even wear, which indicates the need for wheel alignment. When buying new tires, the following considerations should be taken into account, especially if you want to switch to tires bigger size or profile.
All four tires must be of the same construction type. This rule must not be broken. Radial and diagonal tires cannot be "mixed".
Wheels must be the correct width for the tires. Resellers should have tire and rim compatibility charts. Mismatch leads to poor controllability and rapid wear tires. The tread width must match the width of the rim (on the inner sides). For radial tires, the rim width of the wheel should be 80% or less than the width of the tire (not the tread!).
Height of new tires. may affect the accuracy of the speedometer, fuel consumption per unit of distance, acceleration and ground clearance. Tire manufacturers must provide a complete set of measurements.
When loaded, bumped or simply rotated, there should be no interference. The wear indicator appears when the tire is worn.
Tire swap(pros and cons)
There are two opposing opinions about the benefits of changing tires. Since each car owner still makes a decision on this issue independently, here are both of these recommendations.:
1. The manufacturer does not recommend changing wheels. If the tire treads of the front wheels are worn to the limit (wearing out approximately twice as fast as the rear ones), we recommend purchasing one wheel of the same model and putting it on the front axle together with a spare (not worn) wheel. We recommend replacing the least worn wheel (out of the replaced ones) in place of the spare wheel.
2. It is recommended to rearrange the tires every 10 thousand km for their even wear. Swapping schemes are different and depend on whether your car has spare wheel. Radial tires should not be rearranged crosswise (from one side of the car to the other); they last longer if their direction of rotation is not reversed. Winter tires sometimes have an arrow marked on side surface- it shows the direction of rotation. Tires wear out very quickly if the direction is reversed. Studded tires will lose studs when the desired direction of rotation is reversed.
Tire storage
Tires should be kept in a cool, dry place. If the tires are stored in a garage or basement, they should not be kept on a concrete floor, it is better to put them on boards.

Any modern passenger car or freight car can be serviced and repaired independently, in a regular garage. All that is required for this is a set of tools and a factory repair manual with a detailed (step-by-step) description of the operations. Such a manual should contain the types of applied operating fluids, oils and greases, and most importantly - the tightening torques of all threaded connections parts of components and assemblies of the car. Italian cars – Fiat Alfa Romeo Lancia Ferrari Mazerati (Maserati) have their own design features. You can also join a special group select all french cars – Peugout (Peugeot), Renault (Renault) and Citroen (Citroen). German cars complex. This applies especially to Mercedes Benz ( Mercedes Benz), BMW (BMW), Audi (Audi) and Porsche (Porsch), in a slightly smaller - to Volkswagen (Volkswagen) and Opel (Opel). next large group, isolated by design features are American manufacturers - Chrysler, Jeep, Plymouth, Dodge, Eagle, Chevrolet, GMC, Cadillac, Pontiac, Oldsmobile, Ford, Mercury, Lincoln . Of the Korean firms, it should be noted Hyundai / Kia, GM - DAT (Daewoo), SsangYong.
Recently Japanese cars have a relatively low initial cost and affordable prices for spare parts, but recently they have caught up with the prestigious European brands. Moreover, this applies almost equally to all brands of cars from the land of the rising sun - Toyota (Toyota), Mitsubishi (Mitsubishi), Subaru (Subaru), Isuzu (Isuzu), Honda (Honda), Mazda (Mazda or, as they used to say, Matsuda) , Suzuki (Suzuki), Daihatsu (Daihatsu), Nissan (Nissan). Well, and the cars produced under the Japanese-American Lexus brands(Lexus), Scion (Scyon), Infinity (Infiniti),
With the onset of winter, many motorists may wonder how to properly pump up winter tires. Someone may say that this question should not arise, because the manufacturer has already indicated everything required parameters in the instruction manual, which are duplicated on special plates located either on the car body or under the hood. However, the recommended pressure may be too high for winter driving.
Of course, all the recommendations that you can find on the installed plates and in the instruction manual, of course, must be followed. But if we talk about tire pressure, it is worth remembering that these parameters are great for driving a car on flat road in summer. But in winter, in rather difficult conditions, the recommended pressure can be too much.
Experienced motorists reduce tire pressures for the winter, so they increase the grip of the wheels on the road. Which is very important in winter. At this time, the roads are either covered with snow or covered with a thin layer of ice, so it will be useful to under-inflate the tires a little. For example, if the manufacturer indicates a pressure of 2.4 atmospheres, then it is better to pump up the wheel to 2.2 atmospheres.
As a result of pressure reduction, the permeability of the machine increases. And the car will drive better snow covered road, as well as on ice. This is due to the fact that a flat tire has a larger area of contact with the road compared to a fully inflated one. In addition, thanks to this, the wheel runs softer over bumps in the road, which are plentiful in winter. This makes driving and travel in general more comfortable.
However, in addition to more comfortable and safe driving, this method has several disadvantages. First of all, it is worth mentioning a relatively small, but increase in fuel consumption. For example, if you under-pump 0.2 atmospheres, then the consumption will increase by an average of 0.2 liters. This is due to the fact that with such a level of tire pressure, it is more difficult for the engine to set the car in motion, which increases the cost of gasoline. However, it is worth it to protect yourself and increase patency.
Many may say that rubber wear can also be increased in this way. But such a small indicator of 0.2 will not be decisive in this matter, it will not be able to affect wear as much as you might think. It will be so insignificant that it will be quite difficult to notice.
The maximum speed will also drop. However, in winter period and it is not recommended to drive, because this can lead to very disastrous consequences. Sometimes, there are such difficult situations on the roads that even driving at a speed of 60 km / h can be difficult and unsafe.
In order to pump up the wheels to required level pressure, you need to take a pump with a sensor. It is not necessary to look for a sophisticated electric one, an old mechanical device is quite suitable. Connect it to the wheel and inflate to a level less than recommended by 0.1–0.2 atmospheres. It all depends on the model of the car and the diameter of the wheels.
As practice shows, such a life hack is popular among motorists and really helps to significantly increase the cross-country ability of a car and the adhesion of wheels to the roadway.
