That is why it is impossible to put only two winter tires on the car

Here’s how a car behaves with winter and summer tyres on two axles at once

Most of us live in places where winter snow is a phenomenon quite familiar and normal. However, the duration of the presence of “the Snow Queen” in a particular area can greatly differ in duration, from a few months slight frost in the South, up to nine to ten months in Northern areas.

Those drivers who live to the North, of course well prepared for the vagaries of nature. The motor is in season is always filled with winter oil, so as not thickened in the cold, in the tank splashing the “Arctic” diesel fuel, to form flakes of paraffin, and the machine is mandatory “change the shoes” in winter rubber. And this is the right approach.

However, there is another category of motorists who live far to the South and for which short-term winter season does not become an obstacle to the use of their cars on summer tires. They usually think: why do I need to set, if the snow lie down for a week and melts? And the next freezing and the ice is still not known whether or not. Why bare pavement winter tires to wash, thorns to pull out? So it is better to wait out the winter on the vsesezonka or on summer tires.

This is an extremely dangerous argument, you can’t do that and it’s NOT clearly spelled out in the law (paragraph 5.5. of Annex 8 to the Technical regulation of the customs Union “On safety of wheeled vehicles”):

In the winter months (December, January, February) are only allowed to use winter tyres. The requirement on November 11, 2018 applies only to vehicles of category B (passenger cars and trucks N1, M1), and the time of operation of winter tires can be extended depending on the region. But at the very least three months of the year (December to February) – be kind shod in winter tires, and then suddenly the ice, and you are unprepared.

But, there is another category of motorists (rare, but it seems still meets in autopause) who are kind and are willing to put “winter” on the wheels, but only two tires. On the front or on the drive wheels. On the second axis they leave for the summer or year-round option.

Just say that’s a bad decision, it also diverges apart from the law: according to point 5.5 of Annex 8 to the Technical regulation of the customs Union “On safety of wheeled vehicles”: “Winter tyres are fitted to all wheels of a vehicle”.

On the one hand, it seems not so terrible, but in reality, the decision may have even more dire consequences. What? To do this, go to Goodyear testing facility in the Arctic circle by four-wheel drive with basically leading the front wheels of the BMW X1 to see how bad it is.

The experimenters held the vehicle, which are front winter and rear summer tires, through a series of tests: – in the hill, basic turning, braking, changing lanes…

Here the car loses traction and goes into a skid after simulating the lane change:

The front wheels are trying their best to keep the crossover, but rear tires just can’t do your part. The result of experiments clearly looks worse than you can imagine, the car becomes completely unmanageable. That’s why never put summer or all-season tires on the same axle, mixing them with the winter tyres on the other axle. Moreover, paragraph 5.5 of Annex 8, the simultaneous use of studded and non-studded tires on the wheels of the vehicle are also prohibited. Why? The result can be similar to the above.
