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 is the widest Sport R fitment at 13.5 inches of section width, and unlike most sizes in the line it is a standard load rather than extra load construction. It is a summer compound and is not suitable for use at or below freezing.
