Greyhound Tyre Pressures.

RV Load Inflation chart.

As always the higher the tire psi the better mpg but harsher ride.

Each tire manufacturer will have a slightly different PSI table.  My 11R24.5 Firestones can handle about 300 lbs more than the Michelins at 105 PSI.

I have Kumho 12R22.5 tires on our MC7. I have only been able to find a chart that shows max load at 120PSI. The max load on my Kumho tires is the same as on the Michelin chart (that Sojourner posted) for both single and the duals at 120 psi, so would it be fairly safe to assume the max load at 90 PSI would be the same as on the Michelin chart. I would prefer to run with 90 or 100 PSI and according to the Michelin chart I would still be about 500 lbs under max load at those pressures with their tire.
