Just picked up our new Tiffin Phaeton 44 OH. Driving through the mountains in TN I reviewed the pressure of the tires and they were reading 127+. When we stopped and let the tires cool down overnight I dropped the pressures to 110. I believe they had to have been set to 120 from the factory which is max psi. Our last unit was a Newmar 41 foot and I ran with 105. Any suggestions on correct psi including the tag? Thanks
