Experts told what to look for when choosing winter tires

As the autumn temperature approaches near-zero values, motorists should “change” their cars to winter tires. Experts strongly recommend not to wait for the sudden start of winter and change tires in advance. How to choose winter tires and what to look for – in the material “Gazeta.Ru”.

Choice the type of winter tires primarily depends on the characteristics of the region of residence of the car owner, tire manufacturers and experts note. Modern studded and non-studded models already have very similar characteristics, they note. However, from the point of view of safety for the conditions of the Russian winter, options with spikes are still preferable, says Alexander Parkhomchuk, head of customer support at Nokian Tires Russia.

“For most car owners it is better studded tires are suitable from a safety point of view. Beginners and motorists with little winter driving experience, as well as those who often travel out of town, should choose a model with spikes, “the expert advises.

According to him , the main advantages of the “toothy” tire appear on ice, as well as on roads with packed snow. Non-studded (also called friction) wheels are primarily designed for conditions with temperatures near freezing, as well as a lot of precipitation in the form of rain and sleet, says a tire company spokesman.

“We recommend using this type of tires, first of all, in the regions of the Southern Federal District,” Pakhromchuk added.

The tire expert and tester agree with him. Autoreview “Oleg Rastegaev. He recommends studded tires to those who often travel out of town. At the same time, the prevailing opinion that friction tires are preferable in urban conditions, he considers already irrelevant.

“Studded tires work most efficiently at temperatures between –5 and –25 ° C.

Carbide studs in the studs bite well into ice, providing more grip than friction models, tire expert Leonid Pashchenko told Gazeta.Ru. When temperatures drop below –25-30 ° C, the ice becomes denser and the benefits of studded tires wear off, he noted. In severe cold weather, the main influence on the characteristics of the tire is already exerted by the elasticity and plasticity of the rubber compound from which it is made.

All the experts interviewed recommend changing the “shoes” on the car when the average daily temperature drops below + 7 ° C.

They note that with lower thermometer readings, the characteristics of summer tires deteriorate significantly. As a result, even on dry but cold asphalt, the braking distance of the car can seriously increase and its behavior can change.

Watch the load

When choosing, motorists are often guided solely by the size of the tire. A very important parameter is the load index, said the official representative of the Russian office of Michelin Georgy Golubev. This indicator speaks of the maximum permissible load that the wheel can withstand, he noted. ), even if the dimensions allow for the normal version.

“Due to the four-wheel drive and the greater mass compared to conventional passenger cars, SUVs and crossovers require modified tires “, – explained Golubev.

“These tires, of course, have a more durable structure and are designed for higher loads. But ordinary tires with the corresponding load index can withstand the full weight of the vehicle with the maximum permissible load on board and with fully occupied passenger seats, “Oleg Rastegaev told Gazeta.Ru.

Some tire manufacturers have already abandoned the selection of separate models for crossovers and SUVs in their lineup, agrees Leonid Pashchenko. As an example, he cited Continental, which for several years has been focusing only on the load index, without tying one or another tire model to the type of car.

Chains and reagents

Forecasters forecast abnormal snowfalls in a number of regions this winter. According to specialists from the Phobos meteorological center, in the center of the European part of Russia, snowdrifts can be about a quarter higher than the norm, and in the lower Volga, in the Kolyma and southern Siberia, the thickness of the snow is predicted to be 1.5-2 times greater than the usual indicators. In addition, forecasters do not exclude abnormal snowfalls in the south of Russia, in the upper reaches of the Ob and Yenisei, the Baikal region and in the north of the Far East.

Experts note that even the most advanced winter tires are often not saved from snowdrifts that often appear in yards after abnormal snowfalls.

In this case, snow chains may come to the rescue of the stuck motorist. According to Oleg Rastegaev, they are precisely designed to increase the grip of the wheels with the coating in deep snow. But on ice, the use of chains on passenger cars is ineffective, he believes. the chain is able to push through a layer of ice. Passenger cars and even SUVs are much lighter, so the chains will slip, biting into the ice, “he said.

for motorists to stock up on a small amount of granular deicing agents. Finding 3-5 kilogram bags with them in building supermarkets or spare parts stores is now not a problem, it will not take up much space in the trunk. It is enough to sprinkle a small amount of the drug under the wheels, and in 5-10 minutes, while the driver cleans the car of snow, the granules will melt the ice, and it will be much easier to start, experts say.
