I have a 2013 FORD CMAX Hybrid with Michelin Energy Saver tires with 159k mi. I talked with Michelin Customer service and explained I was getting even tire wear at 50psi and got 64k mi. on two sets of tires. Tires are warrantied for 55k mi. He said he had no problem with that and would recommend 50psi. I think it makes sense to do what the experts at Michelin recommend.
The Max pressure on the tire is 51psi cold and it would take about 200 psi to blow up the tire. Some are running 55 psi. on these tires too. FORD's recommended tire pressure of 38psi is only a recommendation and is a compromise between ride quality, braking, handling, gas mileage etc. Even tire wear is the important thing here, IMO
