Specialized Purgatory Grid T7 Tire Description:

The Specialized Purgatory Grid 2Bliss Ready Tire is the standard-bearer for light trail tire performance. The new, completely redesigned tread features square lugs that bite in on soft soil, while still providing support on hard-packed ground. Additionally, flexible center sipes fold out under braking force for increased ground contact and adhesion. For further peace of mind, the GRID casing provides the utmost in cut and flat protection at the sidewalls. And to top it all off, Specialized's proprietary GRIPTON compound helps make this the perfect choice for epic trail rides in any condition.
