The backside of the wheels (rims is an acceptable term as well) will have both the max weight rating and the max pressure rating in different spots. Since mach111 said his wheels had 3500 lb etched on them, my guess is that they are not the 110 psi max rating wheels since the 110psi max wheels are also stamped/etched with 3710 lbs max. 3500 lbs would tell me that they are 85 psi max wheels. Yeah, I know you it is hard for some to get under the monty to check things out, that's when you convince someone else you trust to go under and look at what it says or you take off one of the wheels and do the looky-see thing. PS...the wheels are also stamped with their size, like 16x6 that came on my montana with Marathon tires. And they were 110 psi...but I decided I was extremely lucky to have no damage to the rig after 2 blowouts on the same trip and so I went with new wheels and tires that handle 4800 plus lbs and greater than 125 psi.
