Hoosier to Launch New Rain Tire for SCCA’s Formula F Category

Hoosier Racing Tire — Fri, 24 Jul 2026 04:00:00 GMT

Lakeville, Ind. (July 22, 2026) – Hoosier has updated the rain tire for SCCA’s Formula F category. The change is in response to a diameter discrepancy that existed between the 185/60R13 W3 rain front and 185/60R13 R60A dry front. The new front rain tire will be approximately 0.8” taller in diameter and will have a new “185/65R13” size designation. This change eliminates the need for any ride height adjustments when switching from slicks to wets. The rear rain tire will remain unchanged as a 205/60R13.

The new wet tire specification will have the same compound, molded tread pattern, tread depth, and construction as the predecessor. The only difference is in the visual appearance of the sidewall. The new Formula F rains will now have a black serrated sidewall design (as depicted) and will no longer carry the white letter “HOOSIER” logo on the sidewall.

LAKEVILLE, IN (October 30, 2025) – Hoosier is proud to announce a new multi-year agreement with the Sports Car Club of America (SCCA) to supply a custom “SMX” DOT approved semi-slick and “SMXW” DOT approved rain tire for the Spec MX-5 (SMX) class beginning in 2026.

After a careful and thorough two-day tire test held by SCCA, Hoosier’s “SMX” demonstrated the highest overall performance based on data analysis and subjective feedback from three veteran test drivers piloting three equally prepped MX-5 house cars. The test criteria were heavily focused on durability and minimal degradation in performance throughout the life of the tire.

The new “SMX” dry compound has a cold durometer of 60. Its unique rubber formula accepts temperature quickly, has a wide operating range, and delivers a consistent performance curve throughout a race stint. The structure of the tire has an intuitive feel behind the wheel. Drivers noticed a distinct level of confidence, underscoring the “SMX” tire’s exceptional handling characteristics over curbs and predictability at the limit. The accompanying wet tire, “SMXW”, is fitted with the same compound as the well-respected and race proven
