Hey guys. I am new to the site and need some help with tire sizes. I own a 2003 Tundra Access Cab/2WD/TRD Offroad/V8. I replaced to stock wheel and tires with 18'' KMC XD Series Monsters (-12mm offset) on 255/60/r18 General Grabber AT2. I just put a leveling kit on it and now my tires look too small on the truck and is bothering the crap out of me. OCD kicking in. For those out there who have been in this situation before, what is the biggest size tire i can fit now without the tires rubbing? I plan on keeping the same rims and not doing a lift kit. Any help is much appreciated.
