Howdy ya'll, I have a 2009 F250 4x4 with a 4-inch lift currently running 305/55/20's, which is basically a 33 inch tire. Is there any reason I couldn't fit a 37 inch tire under there. I'm worried a 35 inch wouldn't be much bigger than the current 33's.

 

 

With near stock offset people run 37s with a leveling kit, so it should be no problem with a 4" lift (assuming you don't have offset that sticks them way out).
