Default Trailer TPMS

Has anyone added TPMS to their trailer? Any recommended products/advice? This is for my new travel trailer.

I've been using the TireMinder products for a number of years now. Their stuff works well, and product support is excellent. If you register with them, they even have a program to send you replacement caps, seals and batteries periodically. And if something does break, they'll usually send you a free replacement. I've also found that if you look for it, there's often sales available on Camping World. You can still register if not bought directly from TireMinder.

I have an Orange(??) 4 wheel tpms I bought years ago. Planned to do the same thing. Never installed if interested. No idea on the batteries.

The pressure measuring stem caps might be a cost-effective alternative for a trailer. Don't know this particular brand but the general idea:

After suffering several blowouts on the way to and from the track I decided to invest in one of these. I have been using a Dill system for several years and it works great. I like this one as it uses internal transmitters like a factory system that can't get damaged or stolen. The display cycles and updates about every 3 seconds and monitors pressure and temperature. It has an adjustable pressure warning notification that is very useful as well. It actually prevented issues a couple of times. I was on my way to the track once and I noticed one wheel was over 150 degrees and the rest were around 100. We pulled over at a rest stop and I pulled the wheel and it turned out the lining on the brake shoe had separated and was wedged between the shoe and the drum causing a slight drag that was not enough to lock up but going over a bump and dislodging it could have been disastrous. I remove the friction material and cut the electric brake wire on that wheel only and continued with no issues until I could get a new set of shoes. Highly recommend just for the peace of mind factor.

Of course another whole conversation exists on trailer tires of which most are junk. As of late, Maxxis and Goodyear Endurance are the only ones have descent ratings.

Where do you buy/get installed trailer tires around here? Seems like the best (and most expensive) absolution is upgrading tires and getting a TPMS at the same time. Lots of horror stories on blowouts with OEM tires on the RV websites. Of course knowing the % of total on internet reported failures is tough to figure out.

FWIW, the TireMinder products are external stem mounted units. Very convenient, and never had a theft problem after years of use to lots of destinations.

Trailer tires are very susceptible to age and low tire pressure. If being parked for long duration, make sure pressure is at least to minimum for road driving. If low, causing a larger flat spot on the bottom, can lead to a crease in the belts that may be more susceptible to failure on the road. Slightly over inflating the tires for long storage can be helpful.

After many years & miles with trailers, I've come to the conclusion that any trailer more than 5 years should just be replaced. The last 2 trailer blowouts I suffered, were tires that looked decent, with plenty of tread remaining. But one was 6 years old and the other was 9 years old. I don't believe I've ever had a trailer tire blowout on a tire less than 5 years old.

Where are the trailer pics?

i would echo Tony's sentiments.. dont go by looks.. Like a 944 TB/WP service - do it by age, not appearance. Every 5 years or less possible. Make sure you have the right rating tires as well. If the trailer has 4 wheels, consider a second spare- and replace spares too!

I would guess RV dealers could do the tire work. If you have a bunch of jack stands, you could remove the wheels and take them to your "local" tire place.. its just tires on a rim afterall.. What about Radial? Although pulling up with your rig and parking may be diffficult

Hey John,
Paul at Radial should be able to hook you up with good tires if you can take them in loose. You also may want to consider going 1 load rating higher.

If you bought the trailer used, also be sure to have the stems replaced. They age out as well (had one fail on my car trailer). Radial will surely do this but another shop may not.

When not using the trailer, put on white tire covers to limit UV and heat degradation.

Looks a lot smaller compared to the big rigs at the campsites.
