OUTER APEX SIDEWALL features a secondary bead apex that acts as a heat shield to protect the internal casing of the tire, resulting in confident handling and durability with the added benefit of sidewall protection on rough roads and trails. - 3D CANYON SIPE TECHNOLOGY interlocks the shoulders to resist wear from high torque as well as providing additional handling stability. - AGGRESSIVE UPPER SIDEWALL along with offset shoulder blocks protect the tire from sharp rocks and provide additional off-road traction at low tire pressures or in off-camber situations. - SILICA TREAD COMPOUND delivers superior wear life and wet performance (non-LT sizes). - HEAT DIFFUSER TECHNOLOGY in the lower sidewall dissipates heat to protect the internal tire components. Keeping this critical area of the tire cool ensures vehicle stability even when towing or carrying heavy loads. - RUGGED AND RIGID TREAD BLOCKS feature support ramps and step-down features that provide tread-pattern rigidity in the contact patch, enhancing vehicle stability and handling while also preventing stones from becoming trapped in the grooves. - DEEPEST TREAD IN THE CATEGORY provides long lasting wear as well as consistent snow and hydroplane resistance throughout the life of the tire (*LT Sizes, 20/32nds inches).
