PSA for all us SPB racers, PCA has confirmed that the Toyo RR is the ONLY authorized dry tire for this season.

Plenty of RRs still in stock.

 

The RR is also still the only tire available under the Toyo rebate program for 2024. You can not turn in Toyo rebates for the R as of yet.

 

We’ve been testing the new Toyo R at non-racing events: Buttonwillow, Laguna Seca and Sonoma so far. Great tire, grippy with long life. Unofficially it’s 1-2 seconds quicker than the RR.

Should be a good tire for SPB next season.
