This is a set of two Pro-Line Wedge Gen 3 Carpet 2.2" 2WD Front Buggy Tires, designed for Indoor Carpet Off-Road Racing. The Wedge Gen 3 features an updated carcass shape that provides more steering in low-speed corners and more forgiveness and stability at high speeds. The third generation Wedge features the same iconic and dependable hook-shaped pins, which provide the grip you need without being too grabby. Pro-Line engineers have perfected the carpet compound options of Z3 (Medium) and Z4 (Soft), which have been developed specifically for the needs of Indoor Carpet racing.
