The Mini Master tire was specifically created and engineered for Mini ATV XC and ATV MX applications. Following the same X-type lug design as the bigger XC-Master, the Mini Master's tread pattern was developed to help dig into terrain and hook up, giving riders superior acceleration and unbelievable braking power. Made from a soft, yet durable compound, the Mini Master is great at conforming to surfaces and terrain. From muddy conditions to hard pack, sandy to blue groove, the Mini Master provides excellent traction and performance, without sacrificing rider control or responsiveness. Sold individually.
