275/40/17 I had to trim a bit of fender lip off.
I cant find a good shot of the fronts but LRS sent me a 17x9 front wheel when i ordered 17x8 and i ordered tires from somewhere else and couldnt return them so i have 235 40s on a 9in rim there is a bit of a stretch. The tires would have looked much better on an 8in. rim though. Also the 9in rims dont rub on my car but i have a drag set up so not too low in the front.
Rolling fenders is not the easiest thing to do unless you know what you are doing. I know how it works but dont know how to do it. Gotta heat the paint and be really careful not to flake the paint off. I used a grinder with a cut off wheel and carefully just cut the lip off mine but i run more than just the street tire. i needed as much space as i could get.
No problem i had 275 17s on my 87 also just need a little fender roll love and its fine.
