You can fit 255's up front easy with some bashing. Contrary to what EVERYone believes, my tubs only increase height clearence for suspension travel. Since the fender well now starts at the frame rail where the factory one starts an inch or so lower. Which means I can go lower than most and not have issues.
I've been thinking about turning my muffler into the RE-Anemiya style with a 3.5" turn down tip. Dont know why but I've loved that style of muffler since middle school. I gotta practice my SS welding first.
