I don't agree with this. Inflating a tire beyond what is needed to meet weight carrying needs is not a dangerous thing to do. It will most likely cause the tire to wear faster, but that is it. When the manufacturer prints the maximum carrying capacity of a tire at the maximum pressure listed it means that the tire is safe for this weight and pressure. If you have less weight than the max but you still air it up to max you are not doing anything dangerous.
When a tire is properly inflated, it's tread is making maximum contact with the road surface.
When a tire is overinflated, only the center of the tread is making contact with the road. Less square inches of contact means less traction. Less traction means longer stopping distance when you brake. It also means that steering will be less than optimal even on dry roads, and much, much worse on wet ones.
I'd call that dangerous.

This may be good info for a little car tire with max 32psi or whatever rating, but it is NOT a 1 size fits all is correct recommendation. Period.

Also remember that car tires are over inflated by default to up the gas mileage to meet CAFE requirements. The door sticker amounts to government propaganda and should be viewed with that in mind.

We also have a Class C and at times the ride is rough. We have inflatable shocks. WE set them at 50-60 pounds.
Someone posted an answer to the original poster stating that maybe his tires were inflated too much.

Thanks, everyone. Very informative answers.
I made a mistake...we have air bags, not shocks.
Will get the rig weighed at the beginning of our next trip and go from there.
I have always loved this forum and the people who help me/us!
I only write about tire inflation pressures from the way they are supposed to be inflated and in accordance with tire industry standards.
Bypassing normal automotive tire industry standards and inflating your tires to the load carried is a procedure supported by FMCSA. Those are commercial standards and are not applicable with FMVSS which gives us all the recommended cold inflation pressures found in the vehicle ownerโs manual, vehicle manufacturers -final stage - certification label and on the vehicle load and tire placard.
The recommended cold inflation pressures provide by your vehicleโs manufacturer are considered the minimum safe operating pressures for your vehicle. WRONG!
The U.S. Tire Manufacturing Association (USTMA) will not recommend inflating your tires below the recommended cold inflation pressures displayed on your vehicleโs certification label. NOT A GOOD RECCOMENDATION!
You can find all you need to know about proper tire inflation for your RV starting on page 42 of the reference in the โClick Here!โ tab below.
