Inside dual running hot
Haven’t had the coach out for awhile, inside passengers dual (drive axle) wheel is running about 25 degrees hotter than the other wheels on the drive axle, it’s also 4 PSI higher.
Any thoughts?Chuck

If the pressure is higher than the others when cold (ambient outside temperature) it is highly unlikely when running it will be measurable hotter than others.
Verify the pressure. Then if the pressure is a little more than the others use a temperature gun aimed at the same spot on all 4 drive axle tires to see if the temps are in fact hotter.
My tires are set to the pressures listed on the Michelin tire pressure chart based on the weight carried and after running for an hour or more they tend to be all within 5 degrees of one another with the warmer tires generally on the sunny side of the coach. On a 75 degree day they are also about 15 PSI higher than the starting pressures.
If any one tire is showing temps and pressures different than the others it has my attention. Different from the other tires means a different value for temp and pressure because each of my axles has pressures different than the other axles.

Try swapping the sensors inner with outer and see if it might be sensor?
