Key Features:

• Asymmetric Tread Design — outer shoulder blocks maximize lateral grip in dry conditions while the inner tread zone is saturated with high-silica compound for confident wet braking and hydroplaning resistance
• Bi-Compound Construction — dual rubber compounds across the tread width optimize dry grip on the outside and wet traction on the inside simultaneously
• Circumferential Grooves & Lateral Notches — efficiently evacuate water from the contact patch to resist hydroplaning at high speeds
• XL (Extra Load) Rated — reinforced construction supports higher load demands and provides a more responsive, connected feel
• T0 OEM Designation — engineered and approved as original equipment for Tesla vehicles
• UTQG 300 AA A — treadwear rating of 300, with highest grades for traction (AA) and temperature resistance (A)
