The tires are ready to run, and fit most all modern 1/10th pan cars (remember, tire alone fits F1, not the rims). These tires last for many, many races with drivers using them for multiple season with NO degradation in performance. These are far beyond rubber touring car tires as these are made to grip and made to last. Now available fully mounted and ready to use.
