The Toyo Proxes Sport R is an extreme performance summer tire built for autocross, time attack, and track days. A high grip compound reaches operating temperature quickly, while a reinforced casing with a jointless cap ply and a connected center rib keep the tread rigid and stable at speed. The directional pattern with large shoulder blocks maximizes the contact patch for cornering grip, and the 200 AA UTQG rating meets competition class tread depth requirements.
