Free ride mods - results after a long trip.
For those that care, I was struggling a bit with ride and road feedback on my ACE – F53 Chassis. It drove OK on smooth pavement off the lot - for the first 6 mos, but any sort of harsh road like conc...

I would like to put your data in my motorhomeRV tire pressure calculator to see what pressure advice it gives , so I can check if my determined idea of staying above 85% of the weight the pressure is calculated for to get acceptable comfort and gripp, is right or has to be adyusted.
Already read 6340 lbs on the front axle in a post of yours
So need also rear and configuration like singe or dual load behind.
From tires maximum load and needed pressure for that , from sidewall.
To make it complete also speedcode and sises of tire.
About the temperature.
What TPMS measure is the temperature of the air inside the tire.
Only by driving this rises normally for normal car tires about from 18dgrC/65dgr F outside ambiënt temperature to 45C/112F warm only by driving, so a rise of 27dgrC/47dgrF . LT and truck-tires probably colder because larger volume .
But by severe braking the temperature inside the tire can rise up to boiling point of water even = 100dgr C/200dgr F??. Tires and valves are tested and standardised to stand that temperature and the pressure rising that goes with it.
so only by driving the pressure can rise about roughly 10% but incidentially more.
Edit: reading back I notice that the temperature rises only 5 to 10 degrees but the pressure rises about 10 psi.
this is not what calculations would give , for 10 psi rising so about 12% a much larger temperature inside the tire is needed.
This makes me suspect that or the temperature , or the pressure reading is inacurate.
