Purchased 6 Michelin tires 275/70r22.5 xze2+ (not xza2) Weighted my 99 Dutch Star 38ft. Front axle is carrying 9,160lbs and rear axle is carrying 15,330 and total wt 24,500lbs with full tank of fuel and empty holding tanks. Michelin inflation chart does not show amount of tire pressure to carry in my new tires. Would someone that has the xze tires give me an idea of the correct amount of pressure to carry. They are 18 ply tires. Each tire is rated at 6,940lbs at 130PSI. The inflation chart list shows 85lbs for the xza2 tires but nothing for xze2 tires. Any help would be appreciated. Thanks. Don
