ya, you got plenty of room - it wll be a narrower tire, but will also be slightly taller. I don't think you would have any problems running it. If nothing else you could crank you torsion bars or put a level kit in. You should fill out your info so we can help you. I don't know what year your truck is - if its a 97-03 do the torsion bar twist, 04-09 do a level kit.
