Truck Tire Capacity
Have ordered a 2015 GMC one ton CC SRW SB 4x4 truck. It comes with Michelin LT265/70R18E tires that are rated at 3525 lbs for a rear axle of 7050 lbs. Although I should be OK with stock tires, I would...

I have no interest nor do I anticipate the need to go the 19.5" dia. route. The jump from OEM LT165/70R18E to LT 175/70R18E only increases the diameter by 1/2" and gains 115 lbs of load capacity per tire. The next size jump is LT305/70R18E which is a 2 1/2" diameter jump from OEM and only adds another 110 lbs of capacity above the LT175's. Not worth the extra weight cushion since wheel well clearance would probably not work and a lift kit on a truck carrying a heavy camper is not wise. Again, I should be fine, just wanted to explore all options. Planning to get a Lance 855s with only minor options (no heavy generator). Will install lower stabiloads and call it good.
