Hoosier Announces New Tire for SCCA Spec Miata Class in 2020

LAKEVILLE, IN – Hoosier Tire is proud to release a new P205/50ZR15 SM7.5 designed specifically to meet the needs of the SCCA Spec Miata category. The new tire features the “Intermittent Slotted” tread pattern that maximizes the tire’s contact patch and produces a cleaner, smoother wear appearance. The SM7.5 is fitted with the same construction and compound as the SM7 and will operate at a similar performance level. The SM7.5 benefits from a wider profile that is conducive to extending tire life and heat cycling.
