Our PRO-7 class runs 185/60-13 in either Toyo R-888's or RA-1's.
Bill, What did you mean when you said? "tires were cheaper than Chinese tires locally. "? Toyo makes all their racing tires in Japan. They do have 3 facilities, one in Japan, one in China and one in California. They make any of their tires at any locations except the race tires.

The SpecRX7 class in AZ was the Toyo R888 or RA1's as well but they were allowed to run the cheaper 205's. I think all the Pro7 drivers need to vote in the 205 tires. They are cheaper and available in the RA1's and R888 readily!
