I just ordered a matching set of Toyo Proxes R888R. Fronts are 225/45/17 and rears are 315/35/17. I have not used these tires before but they are primarily intended for the race track and will not last long with a lot of street use. In the Pantera world that means they will last many years. I had to order fronts and rears from two different websites. Both websites are shipping each tire from a different location. Tires for a Pantera are difficult to obtain.
