Road tread pattern consists of blocks or ribs separated by grooves; wide and deep longitudinal grooves serve for drainage of water and mud from contact area, prevent tyre from aquaplaning. Useful contact spot is enlarged for better traction with dry surface. Usage of harder rubber compound and a small quantity of lamellas make tyre more resistant to wear, while road tread pattern makes tyre efficient and less noisy. Road tread pattern tyre is designed for maintenance on roads with improved fundamental surface at above zero temperature.

All-season tread pattern is a compromise between road and winter tread pattern. It is designed for off-roads: wide longitudinal grooves, which are standard for road tread pattern, adjoin a great number of lamellas which are typical for winter tread. Tyres with all-season tread pattern have higher rolling resistance and lower wearing in comparison with road tread pattern, at the same time they have better traction performance on muddy and snowy roads.

Winter tread pattern consists of large blocks formed by variously directed grooves, split by lots of lamellas (small thin slots). Lugs of this tread pattern have sharp edges. It ensures safe traction on snowy and wet road, effective drainage of water, mud and snow from contact zone. More soft rubber compound is used for this tread pattern. Tyres with such tread pattern are designed for maintenance on snowy and icy roads, using of antiskid studs is possible.

• After driving at long distance air pressure inside the tyre increases at average by 0,3 atm. It is recommended to wait not less than 1 hour for pressure adjusting unless tyre is cold.
• When using all-season (M+S) tyres, increase the pressure by 0,2 atm.
• In spare wheel it is recommended to keep air pressure 0,3 atm more than standard pressure and reduce it just before running.
• When trailer using increase pressure in tyres of rear axle by 0,5-0,8 atm.
• Use valve caps.

Correct pressure does not only improve performance characteristics and mileage of "Rosava" tyres, but also guarantees safe driving. That's why it is recommended to use higher pressure for heavy loading or trailer using.
