For the remainder of the 2017 TCS regional races, Tamiya’s pre-mounted B3 tire (item 1015) does not have to be used for any of the GT classes. We are completely SOLD OUT. Instead, racers participating at the upcoming June 25th (NORCAL Hobbies), July 23rd (Access Hobbies and Galaxy Hobby) and August 6th (Brownies Hobbies @ Jackson RC Raceway) may use the un-mounted B3 tire (item 53705 RC 24mm Reinforced Tires-2pcs Type B3 Compound. You may use any Tamiya spoked wheel and any insert of your choosing. Of course, you may still use the pre-mounted tires if you still have them in your possession or have access to buying the remaining stock at your favorite hobby retailer.
For the TCS Finals we will announce a tire that must be used for the two-day event shortly.
