Ron, you and I run the same truck, but I think yours runs 17″ tires. Mine runs the 18″ and that size is fairly slim choosings unless you special order. My Titan is not the Pro4X, just LE 4X4 that had stock goodyear wranglers. After 105K miles and two sets, 4 tire patches, I beefed up with the Nittos.I would stick with tire sizes that are easy to come by, 17s or 20s……….no matter what tow vehicle you choose.96 Eyra/12 Mercury 175 Pro XS with 2015 single axle trailer2017 Victory Gunner
