I put some 315/70R17 Mastercraft Courser ATs on my '03. I had to use a 2. 5 in spacer to get it to where I wanted it. I've got some Bushwacker fender flares to put on it, that will cover them up for the most part. They can get your mirrors with rocks and such. I've been lucky and they've missed but I see them pretty regular coming by the driver window, just above and below the mirror... ... And in the mud, you can gaurantee it to COVER the side of your truck with mud and grass. I've got some custom fabbed steps and mud flaps behind the front tires as well.
