Firestone 625100 Wide Oval Radial ER60-15 RWL Muscle Car Tire

The Firestone 625100 Wide Oval Radial ER60-15 is a bias-look radial tire engineered for classic muscle car enthusiasts who demand period-correct appearance with the ride quality and safety of modern radial construction. Manufactured in the USA using new molds and contemporary materials, this tire faithfully reproduces the iconic Firestone Wide Oval tread pattern and authentic sidewall markings — right down to the correct letter sizing — while delivering the handling, tread life, and comfort advantages of a true radial design.

Featuring a Raised White Letter (RWL) sidewall, the ER60-15 Wide Oval Radial captures the classic look that defined American performance cars of the late 1960s and early 1970s. The raised white letters are built directly into the tire's sidewall carcass during assembly and revealed through buffing after vulcanization, resulting in a durable, integrated finish. This size was a popular factory and aftermarket fitment on some of the most celebrated muscle cars of the era.
