100 front and 100 rear. I did a search on tire pressures vs. weight and talked to International. According to our coach weights, we could actually run less (85-90 psi) but I do not trust lowering the psi under 100. I feel tire heat and stress on the tire would surface at pressures lower than 100. The technicians at International agreed with this. When they service my coach, they always put 100 psi in the tires. The placard on the door says 120 but I would not think of running that much pressure with the little weight we are carrying.
This time of year and when it gets warm again are critical times to change the pressure in the tires. When the weather got cooler, I noticed my pressure had dropped to 90 psi. Last spring when the weather got warmer, the pressures inflated to 105.
BTW, I added the short, braided, valve stem extensions from Camping World to make it easier to check the inner duals. It makes my life much easier when I check or add air. A small pancake style air compressor that I bought at Home Depot will air all my tires to 100 psi so I can maintain the tire pressure at home. It is actually small enough to take with me on the coach and plug in to the outside entertainment center outlet. That way, I could add air anywhere, anytime I needed to. I have not carried it with me thus far but I have thought about is several times (usually while driving down the road and never when I am at home or planning a trip).
