This is a pair of Pro-Line Caliber T 2.2" M3 (Soft) Off-Road Truck Rear Tires for 1:10 Truck. Pro-Line's 1:10 Caliber T 2.2" Truck Tires now available. For the 1:10 Off-Road Enthusiasts, pick your class, weather it's Mod, Stock or Gas truck, but when it comes to tires... the choice is clear, it's Pro-Line's Caliber T 2.2" Truck Tires. The Caliber takes tire technology to the next level by optimizing traction, control, balance, and tire wear with its dual-stage design. The smaller top pin penetrates through loose dirt while delivering unbelievable side and forward bite. The base pin works as a support for the top pin while acting as a dual-stage design once the top pin is worn down. You can rely on the base pin for greater tread life wear and it works well on those tracks that are prone to blue-groove or have a super clean surface.
