Tire Issues on trailer

[kellydog98]

I have a 40ft Fusion with 3 wheels on each side. Just placed a tire pressure monitoring system. Found that the middle right tire wasn't increasing in psi or heat while all other 5 tires were increasing psi/heat systematically. The tread on all tires are equal. Can anyone give me a clue as to what phenomenon is taking place with the middle tire right side. (It appears that this particular tire isn't hitting the road like the others...?).

Before You chase down the possible phenomenon with that tire I would make sure that TPMS transmitter for that tire is setup and working properly. If you have an extra transmitter I would try it on that tire. Some TPMS need reprogrammed when you switch transmitters between tires. Could try to simulate a blow out on that tire by removing the transmitter and then see if the monitor indicates a blow out for that tire.

Already done that research. Even moved the TPMS around 3x just to make sure. Thanks.

On our TPMS, if the tire stem is seated too deeply, it will not allow accurate pressure readings at the sensor - just a thought

Now, that makes alot of sense. How did you come by that fact?

Daryl from Lawrence RV Accessories shared the info with me when I bought our TPMS from him at the Quartzsite RV show. It doesn't take much adjustment. He suggested 1/8 of a turn at a time.

When you say not increasing in temp and air pressure, do you mean not at all or just not as much as the others? If it's not at all you can try turning the valve stem out an 1/8 of a turn at a time as previously recommended, also check that the valve stem is centered at not pushed off to one side.

If it is changing some, but not as much as the others, I'd say there just isn't as much weight on that tire. I've noticed on ours that the right front heats up quicker and gains more air pressure than the other three. The lefts front less than the others. based on slide location and weight distribution, I'd be willing to bet the right front is carrying more weight than the others and the left front less than the others. It's minimal difference so I'm not going to get overly concerned, but maybe I'll change my load plan a bit to see if it makes a difference.

Thanks for all your suggestions, I've also just though of one more. That particular tire was replaced and had a new stem put in. My TPMS us aluminum, however, I believe that this particular tire was stemmed with steel. It made a difference when I ordered it whether they were aluminum or steel. Anyway, my first thought was that the axle was out of alighnment...yuk. I now believe that not to be the case.
