Maximum Tire Pressure
Hello all, I have 235/80 R22.5G XRV Michelin Tires. The side wall states it has a maximum tire pressure of 110 psi when inflated cold. I inflate to 105 psi for the front and 100psi for the rear tires...

If you carefully read what it says on the side of your tires, you will find that it gives the air pressure that is needed to carry the MAXIMUM amount of weight that your tire is designed for.
If you plan to carry the MAXIMUM amount of weight, and you inflate your cold/un-driven tires to the pressure printed on the side of your tires, your TPMS will still show that the pressure increases as soon as you start driving. This is normal and well within the design parameters of your tires.
What you do not want to do is release air from your tires, after you have driven on them, to lower the tire pressure to the maximum pressure for the maximum weight to be carried.
Tire pressure is always set on tires that have not been driven and are based on the actual weight to be carried, as determined by a four corner weight of your RV.
