Tire Pressure Monitors

[sailorii]

If you have a TireTracker monitor(or other brand names this device is marketed under), here is a tip. These are the ones that you can replace the batteries in the wheel mounted sensors.

Mine are only a couple of years old and I remove them in winter and use tire covers. I noticed this year that the o-rings were completely rotted and caught it just in time before I had moisture damage. Would suggest owners check theirs for the same problem.

By the way, the o-rings I replaced them with are already showing signs of failing. Any ideas for a lasting solution?

I've had mine at least 3 years and haven't had any problems with the O-rings so far. The wheels are covered 3 months of the year, but the trailer is used regularly the other 9 and this part of Texas gets more than its share of sun and heat and the sensors remain on year round. That is a good tip to look at them at least when replacing the batteries. Did you get the replacements from a local hardware store or the TPM vendor? They could be neoprene, nitrile, silicone or one of any other compounds designed for particular applications. Some may be better suited for exposure. You would think the vendor would provide rings that are appropriate.
