Keep your wheels in the neighborhood of 5.5" backspacing and you will be ok. Remove your front valance and you may need to trim some plastic in the fender wells. You should be good to go.

A '20" aspect ratio tire on an off road truck is for street posers only. Totally stupid and impractical. You will damage the rim the first time you hit a 4 inch deep pothole.

lets check the math on that one.....20" rim and a 35.5" tire. seems to me he'll have to hit an 8" deep pothole that's at least 14 inches wide. So as long as you stay away from uncovered sewer-holes, I think his 20's will be alright

My tires have lip protectors, and it's probably his DD and not likely not a trail rig. 20's look great on the new trucks. . Street queens FTW!

Stupid pavement pounders and their lifted trucks

My truck sees mud at least once a week.
