I bought an 1981 NASCAR Turbo Trans Am, one year old at the time (in 1982), and it had the Goodyears.
I bought a 1981 Special Edition Turbo Trans Am, and it came with the Uniroyals.
I have owned other 1981 Turbo Trans Ams, and Special Edition Trans Ams, and they both came with either tires.
So, I would guess either would be right.
Your build sheet would tell you.
