The recommended tire pressure for Thor coaches is located ether on the entry door sill (for class B and C) or just above the drivers arm rest on the Class A. For my 18,000 lb coach, the recommended tire pressure is 82 psi even though the tires max inflation pressure (cold) is 95 psi (245/70-19.5). It is always best to have the coach weighed on all four corners when fully loaded for traveling. Using the Michelin tire inflation guide for the size tire that you have, you can determine the individual tire pressures. You should always use the same pressure on tires on the same axle - the largest of the two values. Most add 5 psi to the base values to allow for leakage and temperature changes. Only you can determine what tire pressure are best for your coach.
