This Diamond Back tire is constructed using the Nexen NPriz AH5 tire.Restoring your car on a budget? Then Diamond Back I is the tire for you! These beautifully built tires feature the exact same process, whitewall, and warranty as our more expensive lines but at a fraction of the cost! We currently use a Nexen tire for this entry-level line, which boasts a 460AA UTQG rating, as well as a 112mph speed rating for all 75 series tires and a 118mph speed rating for all other sizes. The Diamondback I also has a rating of 44psi, making it a great candidate for wider whites and extra wide whites. With proper care, the Diamond Back I will last years to come without breaking the bank!
