27580R22.5 tire pressures in Tires Posted March 25, 2018 · Report reply Help..... I have a 34'winnebago MH and the recommended tire pressure is 80 psi according to the Winnebago sticker. I have had several good tires blowout. The place I purchase the tires from (Michelin) thinks the recommended pressure is too low and causing them to get hot and blowout. He recommends I keep 90-95 lbs. Any suggestions?
