That 275 will fit like shit on an 8" rim. The tire guys will hate you for trying to stretch a 10.8" wide tire with a short sidewall over an 8" rim. The 255s will fit better, look better, and ride better, but the 275s will probably fit.

my fronts are 18x9 with a 265/35/18 Id run a 255/35/or45 whatever you have on the back. 275's will look dumb IMO
