I have a '76 st with 195/70 14's and a '77 gt with 195/80 15's, the '77 rubs in the front on the shocks so I put a spacer on the front to prevent that. I want to know what size I can fit on the rear of the '77. I've never driven this car and I've had it for 2 years, I'm restoring it. I think the rear wheels seem small and I don't like the spacer in the front so I was thinking of going with 195/70 14 and I'd like to go bigger in the back to give it a meaner look like the mustang, but I don't know what will fit. Any ideas?

I put 205/60/14 on the rear and 195/60/14 on front, tite but good fit. It also depends on your wheel offset...Louiedog
