The Michelin tires on our 2500TS call for a max of 80psi ???

You have the same tire I assume LT225/75R16.

The tire chart does say Max Tire PSI 80. However the front axle weight of 5000lbs max, for my E450 and I assume for the OPs E450, calls for a max 75psi if you are loading to the max for the axle. If you overload the axle beyond 5120lbs then the Michelin chart says the tire max is 80psi.

Door sticker on my MH says 75psi max fronts, of course that is based on loading front axle to the axle max of 5000lbs.

I got the chart for this tire directly from Michelin just a few days ago. The chart is dated 20151020. These numbers are exactly the same as the chart in the Michelin 2011 data book.

Hope this helps.

Welcome

So I guess I will go back to the original thought, for the Michelin 225/75R16 tire, that if you only load your front axle to between 4380 and 4880 then the tire pressure you want is 70psi.

I weighed my MH a couple of days ago and found, at least for now with what I load, my front axle is at 4760lbs so I will adjust my front tires to 70psi.
