How surely and steadily will keep your vehicle on snowy and icy winter roads, largely depends on the right choice of winter tires.
In the annual commotion that occurs after the first frost or dropped on-to the present winter snow, in lines to the points on the tire is very important not to lose sight of the main points of choosing and using winter tires.
Provide reliable coupling with a road car in conditions when the roadway is covered with a layer of ice or compacted snow. It is studded tyres capable of providing a maximum coefficient of traction, studless same under the same driving conditions will slip.
You can buy ready-made studded tires and you can run studded winter tires. This should take into account that not every winter tire because of the nature of its design is suitable for studing.
Tires with spikes, arranged in a random manner, the coefficient of traction will be much higher than that of the same rubber studded line up.
Spikes with square cross section ensure a more secure grip than the thorns with a cross section in the form of a circle.
Are the best option when riding in the city, when the snow on the roads either completely missing, or in insignificant amounts. Studded tires under braking or acceleration under such conditions would simply slip. In addition, the spikes on the tires when driving on asphalt will wear out quickly, creating quite quite a lot of noise.
The contact patch studded wheels with the road will be significantly less than that of wheels with non-studded tires, hence smaller will be the coefficient of adhesion with the road surface. Therefore, driving with studded tires when driving on bare asphalt will be significantly hampered.
As shown by long-term trials, the most effective are winter tyres with an asymmetric tread pattern, when the outer part of the wheel has a tread pattern best suited for driving on pure asphalt, and on the inner part of the tread is covered by a painting, intended for movement on snow.
When riding on wet snow proved better than other tires with directional tread pattern in the form of "Christmas trees". Due to this structure of the protector wet snow and the water is effectively removed from under the wheels.
Size and stiffness
Size winter tyres as summer, it is not necessary to split hairs – install them the same size, which is specified by the manufacturer in the technical passport of the car. No need to "shod" car in the tires of larger width, the contact patch of the wheels with the road will increase, not arguing, but the load on the tires will be unevenly distributed, causing the factor of coupling of tyres with the road is noticeably reduced.
If rubber passport size pick up is not possible, a compromise would be a tire with a smaller width, but with greater height profile.
The operation of your vehicle in icy conditions or snow the best fit soft winter tires, which will be "stuck" to the slippery road surface, providing the necessary traction.
In the case of driving on clean asphalt surface, it is preferable to use winter tires with a stiffer rubber because the soft tyres, though, and will provide reliable contact with the road, yet will quickly wear out and, when the depth of a protector becomes less than 4 mm and unsuitable for further use.
When to switch to winter tires
"To change" the car should be in the period when the average temperature falls to 70, without waiting for Morozov, falling out of snow and ice formation on the road surface. A large portion of traffic accidents that occurred in this transition period caused by cars, whose owners simply have not had time to change summer tires on winter.
All tires require careful attitude of a few hundreds of kilometers, and winter is no exception. Smooth starting, soft to enter the curve, no sharp braking – this must be your riding style on the initial stage of operation new winter tires.
Winter tires may serve you faithfully, you no nail, no wand!
