Historic Sportscar Racing (HSR) and Hoosier Racing Tire have announced a new, multi-year partnership that will see the Indiana-based racing tire manufacturer become an official partner of the series.

As part of the agreement, Hoosier Racing Tire has been named the presenting sponsor of the series and the preferred tire of the HSR International//American Challenge.

The International/American Challenge presented by Hoosier is a battleground for classic sports cars from days gone by going head-to-head for International, American and Porsche class honors.

Additionally, Hoosier Tire is joining the HSR Tire Village, a platform for tire brands in the paddock at HSR events. The partnership gives the company access to trackside and paddock branding, premium display space and exposure across HSR's digital platforms, print communications, at-track PA announcements and more.
