Hi Joe, you might not need 120 psi in those tires. Most of us that have been weighed by wheel position know that the heaviest side is the kitchen, and those tires are pretty happy with anywhere from 95 to 105psi, depending on your load. Weighing will tell you what is safe, and until you weigh that way, having a bit more air is a good thing. This is only for the 'H' 4805 capacity, 125psi tire I'm talking about. Many of us have switched like you did and have been very happy with the results. Also did you check on the Michelin's as to the speed rating of your tire. Some are not 75 mph but 62 mph.
