I thought there was something wrong with my truck when I installed a new set of Goodyear Wranglers on my truck. At first I thought there was something wrong with the rims since I upgraded from the stock 16's on my 05 to a set of stockers from an 08. With the 17" rims I went with the 265's and the truck was all over the road. It was a bit better when towing my boat and trailer, but on a empty load it wasn't fun. My son thought there was something wrong with the truck the first time he drove the truck....I was glad the problem disappeared after a few runs to the river...
