When the first snow falls, it immediately becomes impossible to drive on the roads: there are traffic jams everywhere, a lot of accidents. Long queues line up around the tire shops to change summer tires to winter tires.
The first frosts come, as always, unexpectedly, when the majority of motorists have not yet had time to change their tires. Such weather conditions are dangerous because the asphalt is covered with a thin layer of ice. Summer rubber, in contrast to winter, at cold temperatures completely changes its physical properties. It becomes harder, and the car ceases to "feel" the road surface. According to experts, you should not wait for the first snow or frost, but change the tires when the temperature outside becomes +7 degrees. The approximate day for changing tires is November 15.
In different regions of the Russian Federation, the change of rubber cannot take place at the same time. But, obviously, if there is snow 10 cm thick on the asphalt, then summer tires will be completely superfluous here.
A double situation is caused by weather conditions, when there is asphalt on the roadway, and snow lies in the courtyards of houses. If you drive mainly on the roadway in the city, then you can think about installing summer tires, because the use of studs on asphalt surfaces will have a detrimental effect on the durability of the rubber.
Outside the city and in the courtyards of houses, with the change of seasons, snow lies for a long time. And if you drive more in such places, or in the evening (morning / night), then change summer tires to winter tires as soon as possible, because melt water turns into ice overnight.
There is a so-called universal rubber, which is intended for driving at any time of the year. But it will be worse than winter tires in winter, and worse than summer tires in summer, like all universal devices.
The moment of changing tires is not regulated by any legislation, so you can ride winter tires in summer, and, conversely, in winter - summer tires. There are no fines for this, your pocket will not suffer from this, but the safety of passengers and the driver himself may suffer.
