Default What size 18" Tire??

I am contemplating keeping the Trans Am but i unfortunately sold my powdercoated black TTIIs and if i do keep it im gonna need solid black rims. i saw a set i like that are 17 front and 18 rear. i liked my 315s but not really seeing 315s in 18" i dont want to spend $300 a tire on em either. i had sumitomos and they were "good enough" for me lol. im wondering what everyone else is running on a 18x10.5?? im stock height again and have rolled fender lips. i dont want to run into ANY rubbing issues. if i dont find what i want im gonna have to get the other set thats only 17x9.5
thanks alot!

315s on an 18" are going to cost you!

My friend just paid $268 a piece.

depends on the brand, alot of people dont even make 315 in a 18. its like 285, 295, then 335. i dont HAVE to have 315, i just liked the wide stance. i dont think i could go any lower than 295 or it wouldnt look tough enough HAHA..

i had 285's and they were a tad narrow for the 10.5 wheel. Side walls were pulled in. I would go at least 295's

I've never personally seen a 335 on an f-body, although im sure its been done. 315's require some work to fit so im sure 335 would be tough to do. Plus I don't think a 335 would look all the great on a 10.5 wheel. My buddies vette has 335's on and 11.0 wheel and they fit that wheel perfect. Almost straight up, just the right amount of bulge outward.
