how fast can you drive on winter tires

The spring sun melts the snow on intercity roads. Many motorists in a good mood accelerate their cars to high speeds. However, they forget that winter tires are inferior to summer tires in terms of speed.

When developing various car models, engineers select tires for them so that they meet the declared characteristics of the car in terms of stability and handling. Almost always, these are summer tires that work well up to a temperature of +7 degrees and lose their properties in the cold. Winter tires always lose to summer tires in all respects and cannot provide passport dynamic characteristics of the car. So that drivers do not forget about this, in Germany winter wheels are accompanied by stickers indicating the permissible permitted speed. These labels must be glued on the central panel so as not to inadvertently go to prohibitive travel modes.

how fast can you drive on winter tires?

In winter and summer, the maximum speed on the country’s highways is limited to 80 km/h or, on toll highways, to 110 km/h in most of countries in the world. In rare cases, there are paid sections with a permitted speed of 130 km / h. Therefore, reminders of the high-speed mode, as it were, are not needed. However, few drivers remain true to the rules. Therefore, before accelerating, it is necessary to carefully study the wheels.

Every tire has a speed index. It is imprinted on the sidewalls in the form of a letter designation and is adjacent to the load index. Winter tires and wheels have them smaller. how fast can you can drive on winter tires depend upon the speed index of tires. The manufacturer guarantees that the characteristics of the tire will be maintained only within the limits of the speed set by him. If you exceed the threshold, then there is a great chance of an increase in unregulated loads and subsequent destruction of the tire.

The international speed index For Tires are:

  • A up to 40 km/h
  • B up to 50 km/h
  • C up to 60 km/h
  • D up to 65 km/h
  • E up to 70 km/h
  • F up to 80 km/h
  • G up to 90 km/h
  • J up to 100 km/h
  • K up to 110 km/h
  • l up to 120 km/h
  • M up to 130 km/h
  • N up to 140 km/h
  • P up to 150 km/h
  • Q up to 160 km/h
  • R up to 170 km/h
  • S up to 180 km/h
  • T up to 190 km/h
  • U up to 200 km/h
  • H up to 210 km/h
  • VR over 210 km/h
  • V up to 240 km/h
  • Z over 240 km/h
  • W up to 270 km/h
  • Y up to 300 km/h
  • ZR “no limits”

The letters A, B, C, D, E, F, G, and J are used on wheels for special equipment, but tires with a speed index of over 120 km / h are made for passenger cars. This is much less than the engine can accelerate. For example, if a car has specific high-profile N tires and it accelerates to 200 km / h on dry pavement, then there is a great chance to end up in a roadside forest since the tires simply will not hold the car when turning.

It is necessary to remember a simple dependence. The softer the wheel, the higher its speed characteristics, but the lower the service life. Therefore, high-speed wheels almost always wear out quickly.

Speed ​​of maximum durability in Winter Tires

With an increase in speed, the load on the tire rubber increases, and its wear increases. “The car first accelerates, which often leads to slight slips on the pavement, and then just as intensively slows down at high speed. Therefore, the durability of tires is affected not only by the maximum speed but also by the intensity of acceleration and braking. Studded wheels are the most sensitive to them.

During sharp acceleration and braking, metal spikes scratch on the asphalt, take on a huge part of the loads and fly out over time. This reduces the grip of the wheel on ice.

Therefore, in order for the winter tire to last a long time, you need to follow a few simple rules:

  • Accelerate without slipping, without spinning the engine over 2.5 thousand revolutions;
  • Brake smoothly, without grinding and screeching;
  • Do not exceed the maximum speed of 110 km/h on dry pavement;
  • Always inflate tires to the manufacturer’s recommended values. Incorrectly inflated tires wear out much faster.
