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...
I think it is best to stay with the size you have now. If you go to 235 make sure they are not touching on the inside of the duals. That is a no no. No matter what you do on tires on a dually they are still going to ride rough unless you adjust the tire pressure between empty and loaded, then is still is not going to ride like a Cadillac.
