In winter, on urban roads is mostly snow-water gruel ("sludge"). Non-studded snow tires, because of its structural features, pushes "sludge" and gets to the hard coating, and "until recently" clinging to the slightest unevenness on the compacted snow and ice. When driving through deep snow winter tire has an undoubted advantage over the all-season, and even more - years. Softer rubber composition reduces the braking distance on snow and ice cover, but more wear on the asphalt.
Studded snow tires primarily intended residents of the region where the ground cover in winter - groomed snow and ice. In contrast to non-studded, studded tires have approximately 10% decreases the acceleration time and braking distance on ice and compacted snow, and a much higher exchange rate stability. On the pavement, all these advantages, because of the reduced contact patch and turn into disadvantages, and indeed the tire wears out faster. The design of modern studded tires contain 90 to 120 studs. When choosing tires is preferable to spikes formed several independent paths. Studded tires heavier than non-studded, so fuel consumption is higher acoustic comfort less, and about one-third reduced smoothness.
Dimension
To understand what the dimensions of tires are put on your car, it's better to look into the manual, rather than focus on the neighbor's garage advice: "Put poshirshe" or "narrower".
When I
Most modern tires designed to operate in temperatures from - 40 ° C to +7 °. For the remainder of winter tires tread should be, depending on the manufacturer, not less than 3-4 mm (Russian requirements stipulate the value of 1.6 mm, but this applies to summer and all-season tires). On modern tires have wear indicator, which tells the time change.
RATE
Choosing tires, pay attention to the speed index: Q - (up to 160 km / h) T - (up to 190 km / h) H - (up to 210 km / h) V - (up to 240 km / h) W - (up to 270 km / h Y - (up to 300 km / h) Snow tires have an index from Q to V. By the way, the use of tires with the wrong speed index can serve as a basis for refusal if the insured event.
from any manufacturer?
Modern technology in the tire industry have reached such a level that the quality of tires from the world leaders is quite comparable. Therefore, choosing winter tires from a reputable manufacturer, you can be assured of quality and brand name on the sidewall of tires depends only on your personal preferences.
