1978-1982 C3 Goodyear GT Radial Tire P255/60R15 - Raised White Letter
1978 marked the arrival of true performance tires for the Corvette, beginning with the Goodyear GT Radial P255/60R15 under RPO QBS. This was more than a cosmetic upgrade—Corvette finally had a radial tire designed to match its growing chassis and suspension capabilities. These high-performance P-series radials quickly became the standard for Pace Cars, Silver Anniversary editions, and 1979 models.
This reproduction Goodyear GT Radial captures the exact original appearance and sidewall details—including the iconic “FLEXTEN” marking—while being fully DOT-compliant and modern in safety and performance. Though originally offered only on select models, this tire is dimensionally correct and suitable for any 1978–1982 C3. It fits both front and rear positions and mounts to factory wheels without modification.
