You can get them up to 120 psi but it is slow. I required that on my front tires due to axle loading. Ultimately put a larger tire on the front, allowing me to run at 110 per Michelin charts. Duals and tag axle run at 80.

What is on the side of RV tires (24" and 22.5") is NOT the maximum the tire should ever have, it's the MINIMUM to support the MAXIMUM rating of the tire.
The pressure on the sidewall of a Michelin RV tire and many others is not the "Maximum" the tire should ever have (unlike car tires) it is the minimum to support the maximum rated carrying capacity of the tire.
More than a little caution needed if reading MrD's oft-repeated mantra. One caution relates to the maximum pressure rating of the rims which in many rigs is the limiting factor and is rarely mentioned.

That is why you need to weigh each axle correctly. I think everyone has less than the max weight that the tire can carry. I for one want a little margin.
So the inflation tables should be used.
You will see that the highest value in the table will match the psi & lbs printed on the side of the tire. Higher than needed psi will give a rougher ride.
