I have an 06 F250 KR FX4 and its time for new tires. I have aftermarket 20's w/ 275/65/20 now. Will 37's fit? 37/12.50/20 or does someone have a better suggestion? I would like to go bigger than my current size.
Thanks

a 37 is a pretty tall tire, but a 37x10.50 could probably work with some trimming. I don't know how oversize tire clearance exactly works on ford bodies, but its not so much clearing the tire sitting on the truck as it is not rubbing when you hit a bump turning, which some trimming on the inside of the fender/bumper can remedy.
