The Proxes Sport R is Toyo's 200 treadwear competition tire, carrying a 200 A A UTQG grade with a 7.2/32 inch tread depth that meets the minimum depth rules of most 200TW race classes. A directional tread with a connected center rib and large shoulder blocks holds a long contact patch under load, and the high grip compound is formulated to reach operating temperature quickly for autocross, time attack and HPDE sessions. This 15 inch size is one of the few Sport R fitments rated V rather than W, reflecting its smaller diameter. It is a summer compound and is not suitable for use at or below freezing.
