Why are tyres divided into winter and summer tyres?

Seasonal replacement of tyres is carried out to ensure road safety. Various weather conditions in Kyiv require different performance characteristics. For example, snow on the road increases slipping, that Rosava winter tyres can overcome due to their tread pattern and the soft rubber compound in tread. Rain may cause bad gripping on the road, that’s why summer tyres should drain water from the contact patch due to wider grooves. This explains the differences in the manufacture of tyres for different seasons. Winter and summer passenger car tyres differ from each other by rubber compound and a tread pattern.

Things to consider when choosing winter tyres?

The tread pattern of the winter tyres consists of a large number of deep grooves and lamellae in the tread blocks, that bite into snow and ice and provide optimal grip on the road. Lamelae, which separate blocks, have good self-cleaning properties, allowing the tyre to bite deeper into hard snow or dirt.

Rubber compounds in winter tyres have more natural rubber, which makes them flexible at low temperatures. The more soft they are, the more secure they hold the road. Good grip with a smooth surface provides a short braking distance of the car and cornering stability.

Winter tread pattern can be: 

  1. Symmetrical directional (arrow-shaped in the direction of movement) with wide grooves in the V-form, which prevent aquaplaning and non-directional (identical on both sides) with uninterrupted grooves from the center to the sides in the form of ribs and blocks. Such Premori winter tyres are efficient in conditions of mild and severe winter.
  2. Asymmetrical - combines many tread patterns for maximum adhesion on all surfaces. The inner and the middle parts are developed mainly for wet and winter grip, and external, with large blocks of tread - for gripping with a dry surface. The main task of such tyres is to provide stability, good handling and a short braking distance on a snowy or iced surface. Therefore, their rubber compounds are more flexible, allowing the tread of winter tyres to remain soft. This allows you to hold the road in extreme weather conditions. 

The Scandinavian type of tyres is designed as studdable. Due to a specially designed rubber compound, the undertread layer of the studdable tyres ensures reliable fixing of the studs.

Which rubber is better: studdable or nonstuddable?

When choosing between studdable or nonstuddable (friction) tyres, their future operating conditions should be taken into consideration. The studs are effective during maneuvers on the ice, improving and stabilizing the gripping properties of rubber. However, on the asphalt road, they impair handling of the car, while creating a sound discomfort. Therefore, there are two options: to buy a set of already studded winter tyres, or buy studdable tyres to be studded in the future (with evenly applied holes for studs in the area of the tread).

When is it necessary to replace the winter tyres?

When the temperature is + 7 + 5 degrees Celsius for a week, it's time to "switch" tyres. But first of all, be sure to evaluate the condition of each winter tyre. Pay attention to the wear of the tread. It is recommended to use winter tyres up to a depth of 3.5 - 4 mm, after that they can be used in summer.

When choosing Premiorri winter tyres, pay attention to the marking as well. It is very important to be able to correctly read marking on the tyre. It indicates the size of the tyre, the corresponding diameter at rim seat, the speed limit and the year of manufacture of the tyre. As a rule, it is recommended to use winter tyres for a maximum of five years, subject to the storage, transportation and operating rules.
