Aluminum Rim only rated for 60PSI

Looking at their "tech catalog" they have a 2500 pound and 3000 pound capable wheel. If you have the 2500 pound wheel, you have a wheel with less load capacity than the tire. Hopefully you have the 3000 pound capacity wheels. Their "tech catalog" is pretty short on technical information.

It seems that you now need to ask them what the service pressure is for the wheels. Seems like they've danced around the question.

I don't know if I would let them off that easy. Since when would they stamp a max pressure for bead seating? Sounds fishy to me. Look at their website and see if you can find the model of rim that you have. The specs are listed for each model.

I've finally gotten my answer from the manufacturer of my wheels. This is a direct quote from Ultra Wheels - "The maximum PSI engraved on the backside of Ultra Wheels specifies the maximum bead seating pressure the tire installer must not exceed when installing tires on Ultra Wheels. The engraved PSI is not related to service pressure." Thank you everyone for you help and concerns. I certainly feel safer.

Thanks for all of the info. Jayco has been notified of the situation and a complaint form has been filed with the NHTSA. Will keep you posted.

What JAYCO has done is mirror FORD's Load/Pressure numbers for maximum Axle Load and the 225/75R16E standard tire. Back when E450 front axle GAWR was 4600#, the tire pressure spec was 65# Front.
This Michelin Chart shows Load per Single Tire as 2335# at 65PSI for 4670# of tire capacity on a 4600# rated axle. Then FORD went to 5000# front axle rating. The nearest round number for inflation that didn't fall UNDER axle capacity is 75PSI for 2560# per single tire or 5120# tire capacity on a 5000# rated axle.
Note on the chart how the Dual application reduces the tire's load rating somewhat. That's why we often see full sidewall pressure 80PSI on the rear based on load. Note too, that Michelin Chart shows Dual Loads as Per Pair. The "truck" version of the chart is by AXLE. The RV version I linked is by CORNER. They're trying to tell us to get Four Corner Weights since they've noticed RV's are often unequally loaded side-to-side. Tire pressures should be set equally across an axle to the highest required number. For example, if Left calls for 70PSI and Right calls for 65PSI, BOTH should be set to 70. Michelin just doesn't want us thinking we're OK with an overloaded corner just because the axle weight is OK.

Odds are the front tires will not actually require the 75 PSI based on weight. Probably quite a bit less. I don't have the link at hand but your tire mfg has a weight chart which shows recommended PSI at various weights for the tire. You'll have to weigh the rig (get weight for front and rear) and base your inflation on that. The rig will steer better if the front tires are not overinflated but inflated based on weight. I'd be far more concerned about the rear tires if they have the 60 PSI limitation. Are the wheel ratings the same back there? It is very likely based on weight your rear tires will be well over 60 PSI.

Just as an example my class C only requires 50 PSI in the front tires based on weight.

Front tires require 75 PSI via Jayco placard on door jam. Unit has just been purchased by myself from a Jayco dealer second hand.

Did you purchase it new? Even most front tires are 65# which would make all your wheels under what is needed. Dick

Yes on calling Jayco for the correct sticker of the wheel. :)

I for one had rather be PSI over the wheel rating than 20 under on the tires.
