Yes, another tire question...
I've weighed and according to the Goodyear chart I should run 80 psi in all tires. The MH handles very good at 80 but the tires increase in pressure as they heat up and it's not uncommon for them to p...

There is a reason why the manufacturer has a tire chart and why they say to inflate the tires to the specified temperature when the tires are COLD.
Driving around with a fully loaded coach, or even an empty coach, still puts a large load on your tires. Enough of a load that if you drive with 75 PSI in them, there is a good chance you will damage them and at some point in the future they may fail.
Actually, to be safe, if the chart specs 80psi, I would increase that by at least 5 PSI to 85 PSI.
The flexing of the tires is one thing that cause them to heat up when driven. Inflating to 85 PSI may decrease the flexing enough so that the tire pressure increases less than 15 PSI. In any case, at 85 PSI it gives you a little margin of safety for the inevitable small loss of air.
If you inflate the tires to 80 PSI and your coach handling suffers when they increase to 95 PSI because of heat, the problem is with the coach and not the tires. Correct the suspension, loading, or alignment issues and your coach should handle like everyone else's when their tires get warm under NORMAL circumstances.
