Summer tyre pattern Summer Tyres
The main characteristic of the summer tyre is excellent driving and braking performance on both dry and wet roads, in temperatures above freezing throughout the spring, summer, autumn and winter. A simple block-shape tread pattern ensures the tyre's contact area remains as rigid as possible, ensuring maximium grip at all times by optimising friction with the road surface. If the tyre has any special indication on it, it means this tyre is for summer usage.
Winter Tyres
This type of tyre is suitable for snow and ice covered roads. The tread pattern features a heavily siped, fine-block design with grooves that are deep and wide, providing excellent driving traction and braking performance on winter road surfaces. The tread rubber used in winter tyres provides good friction characteristics and suppleness even in low temperatures. At present, winter tyre design is focused toward braking performance and driving control on icy roads. Recent developments in tyre pattern design and rubber technology have greatly improved winter tyre performance.

All-season tyre pattern All-season Tyres
These tyres are designed to be used all year round to save having to change the tyres to suit the season. All-season tyre patterns are more complicated than those of the summer tyre because of the longer block-edge for winter usage. More sipes appear in the all-season tyre than summer tyre to improve the braking and driving performance by maximising the effect of edge. It is important to remember that in regions where winter temperatures are very low and heavy snow falls are frequent, braking performance will rarely be 100 percent so it is safer to use winter tyres. All-season tread designs will provide good all-around traction for varing road conditions, but still provide good treadwear and tyre noise characteristics.
