Winter tires



Most drivers have long decided for themselves that in winter it is necessary to ride only on winter tires. However, there are also those who still doubt. They believe that once the roads in the city are cleaned, then it is possible and not “change shoes”, and the winters we do not seem very harsh. Also, the reluctance to “change shoes” contribute to various myths about winter tires. Let’s dispel some of them.

Winter tires


The bigger the size and width of winter tires, the better.

This statement can be attributed to summer tires, because the car really gets some advantage in handling with increasing tire sizes (not wheels!) If we talk about winter tires, then the characteristics when driving on asphalt do not change at all, when driving on the rolled snow and ice changes in characteristics are negligible, and on wet asphalt and loose snow, wide tires are more susceptible to aquaplaning than narrow ones. The tires will “float”, and the protrusions of the protector will not be able to grasp the surface of the road.

Studded tires will save from any winter troubles.

No studded tires can guarantee safety if the driver does not comply with traffic rules and speed limits. Studded tires in comparison with neshipovannymi have the advantage only in icy conditions and on rolled snow. If roads are cleaned and sprinkled with salt, the coupling properties of studded tires will not improve, but will remain the same as those of the studless, if not worse.

Studded tires are worse than friction tires.

Another option: Friction worse studded. All tires are good in their own way. Studless winter tires have good performance in terms of noise, handling, they are economical, lighter, durable, have lower rolling resistance, and usually provide good grip. Studded tires win in the non-stopped braking distances: on ice – from 20% to 50%, on snow – 5-10%, on asphalt, on the contrary, the stopping distance may increase, but insignificantly (by 5%). At start and acceleration the car with “spikes” wins up to 30% on ice and up to 10% on snow. Therefore, when choosing winter tires, you need to decide on which roads you will travel the most, and put suitable tires.

If there are all-season tires on the car, then you do not need to “change shoes” either.

In fact, universal tires do not exist. All-season tires represent a compromise between summer and winter tires. The pattern of their tread (in comparison with winter ones) has a smaller depth, it is less sparse. And the composition of the rubber is not so soft. Such tires are good enough on dry and wet asphalt. They provide rather good coupling properties, are economical and comfortable. But on the ice, loose and rolled snow, they should not be demanded of high traffic and good coupling properties. Stability, controllability and efficiency of braking all-season tires on the winter road are average. And winter tires are specially designed for operation in conditions of low temperatures, in mud, on ice and snow. Coupling of all-season tires is 25% less than the grip of winter tires on snow, and 40% less on ice than studded tires.

Winter tires

If I have an SUV (or an all-wheel drive car), then winter tires are not needed.

The all-wheel drive does not provide reliable grip on ice and snow if the car has summer tires. This particularly applies to braking, when there is no particular difference in the design. A four-wheel drive car is less predictable on a winter road than a single-wheel drive, so to ensure better handling, it is necessary to put winter tires on such a car.

Winter tires are enough to put only on the driving axle.

All tires must be the same regardless of the drive. If you install winter tires only on the front wheels, the risk of skidding will increase several times. If the winter tires are put only on the rear axle, then the braking distance will increase, and there is also the risk of the front axle slipping into slip, which is worse than the skid of the rear axle, since it is much more difficult to handle with it.

At high speeds, winter tires do not behave very well.

In the last 5-10 years, the performance of winter tires has improved significantly, modern winter tires provide a high level of control even at high speeds. Tires have a speed index, which is indicated by letters, and means to what maximum speed they can be accelerated: Q – up to 160 km / h; T – 190 km / h; H – 210 km / h; V – 240 km / h; W – up to 270 km / h. Winter tires provide the maximum level of controllability, even at such high speeds, because have a special composition and tread pattern.

Winter tires – expensive.

The price of winter tires in most cases depends on the size and the manufacturer. And in fact, winter tires are not much more expensive than summer tires. Winter tires can be a profitable purchase, because using winter tires, you extend the life of summer tires. Winter tires are operated at lower speeds than summer, and in the cold season, so they serve much longer summer, on average 3-4 seasons. By the way, from the need for seasonal “re-training” on tire fitting, you can save the purchase of an additional set of disks.
