275/40 or 275/45 will fit on the back. Might rub up front, though.

hey whiteflash what kind brand do you use? I heard different brands actually measure differently meaning some 40 sidealls may be bigger than others.

Are you running a 9" wide wheel in the back tho?

275/40/18 or 275/45/18 will be okay

wouldn't put a 285/40/18, it needs a 9.5" wide minimum, preferably 10"

285/40/18 would look really good in the rear. 5th Gear has 285/40/18's on 18x8.5 bullitts, and that fat rubber looks soooo good!

I actually fitted on some 315/35/20s on my 9" saleen rims( i just wanted to slap them on to see how they look) and it didnt look so bad. I actually liked them. Every tire proffesional i asked has told me 315's is fine on a 9" tire and no problems would occur. Im getting on some 295/40/20/s pretty soon and i hope there wont be any issues because i changed my saleen springs to pro kit.
