275/45/18's on 18x8 rims? Not sure if that will work or if I need to go to a 9" or 9.5" rim?
Thanks - duff....

275 is the width. it seems everyone runs 275 60s on 8" wheels, I dont see why not. Go to the summit site and look up the tire section. some brands will recommend wheel width. jim

The range I can see on tirerack.com is 8.5 to 10.5 in.

I know they will fit; but will bulge. You take responsibility if you put them on 8".... I'm going with min 9" as they will probably look better too. Was just curious on what your reponses would be. Thanks for the input.... - Duff.

The bulge from that combination isn't really a look I like (not on an 18" rim). I like a little wider wheels so the shoulders of the tire round off more. It looks sportier to me.
