I have a 2005 Silverado 3500 Duramax. I am looking for a used camper. I need new tires for the truck and want to buy them before I get the camper. The tires I have on now are 215/85R16 load range E...
Yep, that's the beauty of a DRW. Very hard to overload the tires. Depending on what camper you want I would find the rear axle limit rated by the manufacturer. The older trucks had a low GVW rating but you should be able to carry more on the axle. One consideration if you want to use wider tires is the gap between them. Make sure they don't rub or use wheel spacers. You should be good up to 235 or maybe 245 stock.
