tire pressures

I run my tires at high pressure for longer wear and increased fuel economy.

Consider also the manufacturer's inflation specs on the driver side door post. These are for full rated load, so may be a little high.

At this point rather than listening to any of us, I would like to suggest you call Michelin and give them your details. Then ask them for a recommended inflation number. For me, I go by the inflation table. Others seem to have their opinions that differ. You will need to make a choice for yourself.

With only 80 psi in those heavy tires they can heat especially on the downwind side in strong side winds.
Ever watch a motor home lean going across I-40/I-70/I-80 in strong north or south winds. The down wind side tires look half flat. I would add 6-8 more psi for load changes a tall heavy boxy vehicle for dailey dynamic load changes.

The 80 psi is a minimum pressure recommendation for static weights.

I would imagine the folks over in the motor homes forums that probably have the same MH can give you some input on what works vs what sounded good in their motor home.

Some might suggest you add an additional 5psi to account for any additional weight you might pickup during your trip. So 80 to 85 psi.

Those are the weights from the scale
80 all round!
Great, thanks

Based on the weights you provided it would appear 80 psi would be about right for the front as well as the rear tires.

I would put a picture but as usual the wifi at this park is not so hot!

thanks all

load range F or H? it's on the tire. and are those actual weights or the weight ratings of your tires? you need to know the actual weights the axles are supporting.
