I ran a 28x13.5 comfortably, which is a et street or a 325/50/15. Springs moved in 3" and tubbed. A 29" tire doesn't fit well without moving the rearend back. I tried a 29x15.5 but it was very very tight. They didn't really fit inside the wheel well. I had a 15x10 wheel with 6.5 backspace and an a-body 8 3/4. Car was 72 duster. Best tire would be a 325/50 drag radial. Thats my opinion
