Winter tyres

Winter tyres for passenger cars remain elastic in the frost and retain density during thawing. They are installed when the ambient temperature drops below +7 °C. In the summer they are not to be used, as they wear quickly due to the contact with hot asphalt.

Advantages of using winter tyres for passenger cars

Products of this category are indispensable in the countries where the weather conditions do not allow using all-season models. Special ingredients, for example, natural rapeseed oil, are added to the rubber mix. They make the tyres much softer than those of the summer type, which ensures good grip on slippery surfaces. The tread depth is usually 8 to 10 mm, while for summer tyres this parameter does not exceed 8 mm. The tread pattern features enlarged sipes to remove snow mash. This design shortens the braking distance even on a snowy road. The tyres also increase vehicle roadholding ability on roads covered with ice or snow. The use of studded models significantly improves grip. However, their use is permitted by law not in all countries.

6 tips for choosing and buying

1. Buying tyres, bear in mind the peculiarities of the climate in the area where the vehicle will be operated. So, manufacturers offer the following products:
   • European type. These tyres are created for mild winters with frequent thaws. They have many small sipes that ensure efficient removal of wet snow and slush from the contact patch. Drainage grooves are provided on the edges. The advantages of such models include the possibility of operation at high speeds.
   • Scandinavian. Such winter tyres for passenger cars are intended for more harsh conditions, such as extreme cold, on snowy and icy roads. The sipes typically have sharpened edges, and the tread blocks have scalloped edges. This allows the tyres to securely hold on ice or dense snow.
2. Before choosing studded tyres from the catalogue of winter tyres for passenger cars, make sure their use is not prohibited by the law. In some countries, only non-studded tyres are allowed even in winter. Both models have certain advantages. So, non-studded tyres do not damage the road surface, produce little noise during operation, and contribute to better fuel efficiency. Some products have a special design that allows installing and removing the studs when necessary. This should only be done at a service station. Studded tyres ensure short braking distance and excellent grip on icy roads; however, the grip is poor on dry and clean asphalt. Manufacturers use different types of studs:
   • AD — made of aluminum;
   • SD — with a hard-alloy core;
   • DD — with a diamond edge and rectangular pin;
   • OD — with an oval base;
   • MD — made of plastic, with a hard-alloy core.
3. Decide on the tread pattern. For example, if it is directional, the risk of hydroplaning will be lower due to efficient removal of water. However, tyres with a non-directional pattern are much quieter.
4. Give preference to narrow, high profile tyres, if their use is permitted by the manufacturer of the vehicle. They prevent skidding more efficiently, and remove melted snow faster.
5. Install tyres simultaneously on all wheels. Moreover, it is recommended to purchase a spare tyre.
6. Consider the expiration date. Even if the tyres were not in use, do not install them after 2-5 years from the date of manufacture.
