I recently purchased a new 2018 GMC 3500 HD SRW CC 4x4 Gas with 10800 GVWR. GRAWR is 7050. Stock 265/70/18 tires were rated 3525 lb ea. My fully loaded Bigfoot 25c9.4 with wife, dog and I with full fuel, ready to travel was 180lbs (90lbs/tire) under the max tire rating at 80psi. I was not comfortable with the safety margin. I opted to purchase (5) Cooper Discoverer AT3 XLT's size 295/70/18 rated at 4080lb/tire at 80 psi with 60K mile warranty. No mods were done to the truck to fit the larger tires, although my speedo now reads 3.5 mph slow at 60 mph. I recently completed a nearly 4000 mile round trip from MA to FL. I cannot say enough good things about the truck and tire combo. Both preformed great -the tires very very quiet with a nice aggressive tread. .
Interesting I have the same truck though regular cab and switched out the tires for michelin with the 4080# rating. My new 10.4 imo was still too much for the SRW so bought an older DRW, which I feel better about driving. Kind of wish I had a smaller/lighter camper for pulling a bigger trailer to contain goodies. My GMC has the tpms btw which is nice. It was downrated on the door tag for commercial use I believe.
