315/30R21 Continental WinterContact TS 860 S Winter
Category: Winter – Performance
The Continental WinterContact TS 860 S is a performance winter tire with excellent snow traction due to its special traction sipes and snow grooves that interlock with the snow. Thin lateral grooves separating the tread blocks form a stiff rib while braking leading to shorter braking distances in wintry conditions. The WinterContact TS 860 S has big outside shoulder tread blocks that increase the contact area for maximum control and steering while cornering on dry roads, and efficiently reduces the rolling resistance for higher fuel savings without compromising the safety.
3PMSF severe snow service rating indicated. XL (Extra Load) rating indicated.
