Blowout
Well I just had my first blowout, 40' Monaco diesel. This was a 275-70-22.5 Hancook that I put on in February 2012. I really thought they would last a little longer than this so I wonder if I should ...

Max pressure on a hot day is not always the best way to go, you do know tires while under way build heat and pressure, I never run max.
Perhaps a bit of a counterpoint:
Per all tire manufacturers, inflate the tire to the recommended PSI BEFORE DRIVING (that is their definition of "cold"). They know what PSI will do with temperature rise-- after all the Ideal Gas Law is pretty well known by the tire engineers.
This does not suggest that 120 PSI is the correct PSI for his tires/actual weights-- I have no idea if this is proper inflation or overinflated for his coach.
But at what time of day was pressure set, if you set pressure at 7am at max and by 2pm on a hot day it can rise as much as 10 psi without even driving, than add driving on that tire at 10 psi over max and see how high the psi can go.
I'm sorry my friend but that's just not the way it all works. You set the pressure cold - doesn't have to be a critical time of day or even temperature outside. The tire just has to be free from rolling down the road and creating any of its own heat.
Then if it gains 10 PSI rolling down the road that's fine and within the tires design working conditions.
The lower the air pressure, the hotter it will run.
So if your setting your tire's air pressure lower to protect it, your doing just the opposite.
