Dry Performance
The large outer tread blocks on the 420S high-performance tire increase the amount of surface area in contact with the road. This improves dry cornering and handling. 
Even Wear
The asymmetrical, non-directional tread pattern allows for cross-rotation, which reduces irregular wear.
*Consult your tire retailer on the appropriate rotation pattern for your vehicle.
Siping
Siping across the tread pattern provides additional biting edges to help maintain traction in wet weather conditions.
Wet Performance
Center tread pattern effectively channels water for better wet weather performance.

Slanted three-dimensional tread blocks reduce flex for improved handling.
