Driving on snow is the most difficult thing in off-road practice.
I'm serious.

Three tips for your ride:
1. The wheels must be blown off, increasing the contact patch. To the bare minimum you agree to. Be aware of the likelihood of disassembly. Check pump performance and spare tire life.
2. Don't forget the shovel. This is the only means that allows you to ride on _any_ snow.
3. A typical and main problem when driving on snow is starting off.
It is necessary to accurately dose the moment on the wheels, avoiding wheel slip, gradually picking up speed.
On regular wheels And standard engines- it's very hard. the speed of rotation of the wheels is high, the wheels are narrow, the rolling resistance of "asphalt" rubber is very small.
As a result - an instant breakdown of the wheels into slippage ...

Snow is overcome in two ways:
1. Digging up to the "hard" and riding on it.
Realistically, with snow depth somewhere up to half the wheel.
If there is more snow, then a car of the weight of an escuda / niva will begin to float in such snow, resting against the snow with a small gap. who rakes under himself.
With such a ride, the car that wins:
a) has large gaps (less drag snow dump)
b) has fewer "perpendicular body/transmission elements".
Those. there is nothing under the bottom that the snow cannot roll over and that it will rest against.
According to these criteria, the regular Suzuka is much inferior to the field.

2. Swim on the surface.
To do this, it is necessary that the force pushing to the surface be greater than the pressure of the wheels on the snow.
This can be achieved by installing very wide and toothed wheels (which, in your case, is unrealistic) or by gaining high speed (this is already real).
Those. gradually accelerate and try to keep the speed constant in the region of 10-20 km / h.
At such speeds, snow is passed, in which you simply cannot start (the frontal resistance is greater than the traction developed by the wheels before they break into slip).

Basic traffic rules:
1. Try to prevent wheel slip at low speeds. in such a situation, the tread makes holes in the snow, which you still do not have enough momentum to overcome and you will stop.
You may not be able to move out of them.
2. To fly over crossings, clearings, clearings, moldings and other areas of deep snow only in motion, gaining the MAXIMUM speed possible for these conditions PRELIMINARY.
There is always more snow in open areas and it is usually loose (i.e., the traction developed by wheels, especially asphalt ones, is minimal on it)
As a rule, stopping or slowing down in such areas leads to a long use of the shovel.
If you're stuck in the middle of a field, they probably won't be able to pull you either. they will also stick, and even if they can start off on their own, then there may not be enough traction for a jerk.
When flying deep snow, your benefit is that you have a machine gun. which shifts gears without losing traction.
Those. you accelerate, slipper on the floor and flew.
3. Stop only in those places where you can start.
Those. in the forest, in areas of swept land, hard crust.
4. If you need to move off the road in the forest (give way, turn around, etc.), then you need to do this quickly, immediately and in one pass.
It is advisable to find a place where you can drive in one sitting on one continuous path.
Actions: you accelerate, jump out onto pure snow, fly along the trajectory and jump out onto the road in one sitting.
If there is more than half of the wheel off the road, then it may simply not work to turn around in several stages - you will sit down as soon as the car stops.
5. Avoid driving on different heights. Pass obstacles of different heights.
Those. driving off the road, overcoming ruts, paths, snowmobile roads and driving back onto the road on foot.
The snow grip is very small and the slightest skew will lead to a diagonal (i.e. we are not going anywhere).
6. If there are no options (it’s bad everywhere, but you have to drive), then it’s better to stop on even snow.
Those. on the most loose, without ruts and crust.
It will be the easiest to dig out of this.
Stop "partially", i.e. half in snow, half on the road, not allowed on roads/paths/snowmobile ruts. In 90% of cases, when you try to move, you will find yourself in a diagonal.
7. It is better to stop "from the hill".
Those. so that when starting off your car at least a little but went downhill.
Stopping "uphill" can lead to the fact that you can only go backwards.
The most ambush stop is in the ravine, when both forward and back "uphill".
A shovel will help, but it can be very long.
8. If you feel that the car is sitting down (you press the slipper, but the car slows down on the contrary), then in this case you must immediately throw off the gas.
The idea is to disconnect the engine from the transmission.
I don't know how to do it automatically.
The idea is that a car moving by inertia compacts the snow in front of it and under the wheels, increasing the likelihood later, after a complete stop, to leave this place at least back.
After such a stop, go ONLY back.
9. In doubtful situations, always start back first and then, gaining speed, break forward.
Behind the snow is already scattered to the size of the gaps and going back, as a rule, is easier.
10. If you go back to then break forward, then it is useless to pass centimeters.
You need to ride until you pass to a horizontal section, climb backwards up a hill or leave deep snow at all.
Once again, turning back 10-20 meters is more useful than blinking to the diagonal in one place.
It'll work out faster.
11. If the car stopped uphill, then do not even try to move forward or with a slight acceleration.
Roll down to the bottom and make a new attempt to overcome the slope in one go.
The exception is long slides, where it may take tens or hundreds of meters to take back.
In such cases, look at the situation.
Sometimes it’s easier to go around such a hill for a few kilometers than to break into it for several hours.

Rules for following in a group
1. Always wait for the front car to pass the obstacle before climbing it yourself.
Otherwise, you can sit down yourself and lock the front car.
Deadlock from which only a shovel will save.
2. Always leave the car at such a distance from the front that there is a place to turn back to a "favorable" place (beginning of a slope, a flat place without snow, etc.)
3. Before you go by car to "rescue" a comrade - think hard. digging out two sitting cars is at least twice as much work with a shovel.
4. Try to always keep at least one car "on the move".
In case of breakdown of the rest, some emergencies and the like must always have a means by which it will be possible to escape from the forest.
Those. if three cars drive, two villages, then do not touch the third at all - let it stand in the place where it can drive and save the first two with shovels.
5. If you are not forced to stop (there is nowhere to go after the ambush slips through), then always stop so that the car can then go.
It is better not to reach the place of interest for several meters than to dig out later after an unsuccessful attempt to start.

Things and equipment
I think that you yourself understand that trains in the WINTER to the forest are such a thing ... you can also move horses.
Just in case:
1. Have a double supply of warm clothes with you, which should be wrapped so that they are guaranteed to remain dry in any conditions.
2. Have at least a small supply of fuel with you.
In which case, an attempt to make a fire with "matches" from a frozen tree may not work.
The easiest way is to take with you a couple of bags of coal for barbecue and a couple of cans of ignition for them.
There is little weight, but it can be ignited both in the open wind and on bare snow.
3. It is desirable to have some kind of spare parts for the car.
The composition of the spare parts kit depends on the condition of the machine and your familiarity with its features.
But, even if you think that your car is ideal, it does not hurt to have: brake fluid, antifreeze, a couple of packages of "cold welding", a couple of repair kits tubeless tires and a can of gasoline.
4. The basic rule of traveling through the forest in winter: if you sat down and the prospects to get out in soon foggy, then the first thing to make a fire. It will come in handy right now or not - business 10th, but when it is urgently needed it can be even late (dark, very cold, etc.)
5. Gasoline do not spare.
If it is cold outside, then do not turn off the car, do not turn off the stove, so that there is always an opportunity to warm up.
Gasoline will count when you successfully get home.

Well, something like this, I hope you don't get bored :)

PS: Whether and when to turn on the reduced one - decide for yourself according to the circumstance.
Choose what will allow you to start and accelerate in your specific conditions.
On the mechanics, for example, in loose snow and regular wheels, a reduced nafik is not needed - it is impossible to gain speed.
