The Street Tire rule for 2021 is defined as UTQG 200 ~ 249 (also includes Nitto NT-01, Toyo R888R). OTA now joins must sanctioning bodies and series across North America that have instituted a similar definition for a "Street Tire". There are perhaps a dozen or more tires that might be competitive. Got any tire tests, personal data or bench racing opinion on which ones will be the fastest over a 'solo lap'? Of course in the end your personal choice could inevitably be a sum of many factors, including: competitiveness, drivability, tread life, durability, cost, sponsorship, contingency, etc.
Here's a short list of tires that could be competitive, please add more and let see what OTA competitors think:
1/ Bridgestone RE-71R
2/ Yokohama A052
3/ Goodyear Eagle F1 Supercar 3
4/ Michelin Pilot Sport Cup 2 (240)
5/ Nitto NT-01
6/ Toyo R888R
7/ Falken RT660
8/ BFG R1-S
9/ Hankook RS-4
