Getting back to Ty re Trans Am cars and tire and wheel sizes. Checked with Chad Raynal who owns the 69 Z/28 "Mid-Del Auto Parts". (Race 64).

"We're required to run no more than a 15" x 8" wheel on our cars. We happen to run 15" x 8" wheels front and back. The tires we're required to run are Goodyear Sports Car Specials, 6.00-15 on the front and 7.00-15 on the rear. The 6.00-15 tire has approx 8" of tread on the ground, where the 7.00-15 tires has approx 9.

Most all of the Historic Trans-Am cars run this same combo. Only the early Mustang notchbacks tend to run anything different. Their rear wheelwells/quarterpanels often require them to run no more than a 7" rear rim and 6.00-15 tire. Thus, they often run 15" x 7" rims front and back, along with 6.00-15 tires all around. "

I'm attaching a picture of Chad at Wine Country 07 also.
