I am running 38x16x16.5's on my truck and they suck if you are trying to get the most flex out of your truck. After hitting Stag Mtn. this past weekend I am getting some 12.5's or 13's.
oh yeah...my rear tires rub the INNER fender wells on my truck. The front fender wells are coming out, they got banged up this weekend also.
I say go for those boggers I posted on the NJK5 site.
