I just put new tires on my truck today, and they fixed every problem i had hoped they would. The old tires were all 245/75, except the tires on the front were a different brand then the ones on the back. When the tires were off the truck there were nearly two inches difference in height. I just got this truck a week ago, I was worried about the transfer case cuz it wouldn't shift worth a d***. The brakes don't shake any more, and now the truck drives straight down the road. It rides better too. I am always amazed at all the drivability problems that can be attributed to bad tires.
