What Every RV Owner Should Know by Michelin Tires

While talking about tire pressure, they left out one important thing. The Michelin and all other load/inflation charts show the minimum air pressure to support the corresponding load. When the fine print on the charts is read, that statement is on the chart somewhere.
Our resident tire expert, Tireman9, recommends maintaining a percentage over what the chart shows, and says he does so himself.

People should be adding air in this weather. Tires lose one PSI of air for every 10 degrees of temperature drop. I add 10% to the chart pressure, as recommended by Tireman9.

if any body needs math formula just look it up.. every tire manufacturer has different max weight per max inflation . So lets say 6500#'s at 120 psi...well how much PSI at 5500#??????{use math}..so after you weigh your front and back weights Its Just Math to find how much weight per PSI is in equation,,, if you check manufacturer's charts you will find to be so close its a given.. Or I Could Just Post Formula For Ya..

I know this started as cold and psi..some tires lose air just because of seal on install or osmosis and some just don't lose much[like my current set compared to previous set] this is posted for how many psi for #'s on that tire..
I posted this before.. went to Michelin site and for x line energy 2 which is what my coach needs the specs are 7160 max #s at 120 psi..22.5" tires and H rated..
so 7160#'s dived by 120Psi = 59.6 pounds per psi. so the Michelin site says that 6680#'s on tire the Psi should be 110 Psi.. So compare my formula that says 6680#'s divided by 59.6 = 112 psi .. close enough for me. and for some reason every one adds 5 psi to recommended psi anyway. check it out and tell it ain't so.. And it does not matter what brand or size.. just use math per max weight and max psi..

"Close enough for me" is right, when most gauges fine print says "+/-5-psi above 70 psi" or "+/-10-psi" ... grab 6-gauges and see if you can get >2 to exactly match?? I could be wrong :-(
