TPMS Questions

I've noticed since installing my TPMS that regardless of conditions, speed that the left front tire pressure rises more percentage wise and the right rear outside rises less percentage wise. Could there be a logical reason maybe alignment or ??

I have a thought. On my coach the front tires carry more weight than the rear. I don't know about yours. I do know that the side that is facing the sun causes the pressure to be higher than the other side.

A possible reason:
My left front is 600 lbs heavier than my right front, With both tire pressures adjusted for the heavier load, my pressure rise is about the same.

Have you weighted each corner and adjusted pressures according to the tire manufacturer's recommendations?

Are you running the genset with the exhaust going in front of the tire?

Let us know what the outcome is.

I always notice the tires on the sunny side of the rig are slightly warmer than the ones on the shady side

My right front is heavier than my left front due to the propane and hydraulic system being in the compartment just in back of the tire. I've noticed that it will be a couple of degrees hotter than the left front. However, when the sun is shining on the left front, it will then be pretty much equal to the right front.

So...I'd say both the sun and weight will cause this. If you do have one tire slightly out of alignment, I would assume that it may also be a culprit.

When we get home we will do a 4 corner weigh in and will check alignment. Will post results

Are your sensors internal or external?

Internal sensors can provide an accurate temperature reading, while readings from external sensors are much less accurate for temp as they are influenced by environmental elements (wind, sun, etc.). They can however provide some comparative value of abnormalities that might cause a tire temperature to rise. An overheated brake, such as a stuck caliper, a bad ball bearing, or other wheel problems "might" cause a temp rise.

If your sensors are external, you might also want to consider a IR tempurature gauge. These can accurately measure not only individual tires, such as an inside dual, but they can also check wheel bearing temperatures as well as other components.

Have you accurately measured and adjusted the air pressure. A pressure difference will cause a variance from one side to the other.

Uneven weight distribution, as has already been discussed is one of the higher probability culprits.
