Features and Benefits

Feature: Innovative Compound - Longer Is Stronger

Benefit: A raised rubber ridge acts like a bumper to protect wheels from curb damage.

Feature: EPC Tread Compound
Benefit: Reduces the hardening effects of heat for continued flexibility and wet performance as the tire wears.

Feature: Unidirectional Pattern
