Expensive TPMS

Click image to enlarge

I forget the name but I was considering a similar solar powered TPMS because you could add extra sensors for a trailer or caravan which I thought would be useful. It recorded both tyre pressure and temperature and had an audible alarm to warn of pressure loss. As my new car now has TPMS I could just get a cheap system and fit the sensors to my trailer and caravan instead I suppose. I`m away to have a search on Ebay!

Get a second setup for a trailer so you can set the pressure warning at a different level. Procrastination, mankind's greatest labour saving device!

I live near the M5 going south past Bristol. From what I see, a TPMS is more necessary for the Caravan/Trailer than the car.
Although I do think that people are keeping the caravan tyres in a better condition now than a few years ago when the hard shoulder was populated by trailers and caravans awaiting tyres. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

This system shows tyre temp too and has for tyre pressure accuracy it's bang on. Only got it because when leaving home for work and returning home it's always dark so tend not to notice a near flat tyres and I nearly lost a tyre/wheel few weeks back. MY13 HSE LUX Aintree Green

I destroyed a tyre in remote north west Australia, with only one more spare at the next town bought TPMS. We got 3 more flat tyres for the remainder of the trip which I plugged before any damage was done. TPMS well & truely paid for itself. Even more so in the outback as it can cost thousands to get a new tyre & then you have to get it on the rim when you are stuck beyond the black stump. Procrastination, mankind's greatest labour saving device!

Hinchy, looked at these on eBay, cheap no doubt and I am interested, however I guess the TPM caps just replace the valve covers, but what are the 4 nuts for?

You tighten the nut back up against the transmitter so it locks it on so it is less likely to come off.

Adjusting tyre pressures a few times a day is a little irritating at first but you get into an efficient routine after about half a dozen cycles.

Put a piece of fluorescent tape or tag on the small spanner so you do not loose it.

Read a review of one of these kits that found after a few months that the little nuts corroded and seized onto the valve threads making it a sod to get off to inflate tyre.

Might be worth checking periodically. FL2 TD4 GS 60 reg Facelift - so many issues
2019 DS. Terribly unreliable.
Sold DS for a 2021 Mitsubishi Outlander PHEV. Fingers crossed....
Sold Outlander for a 2014 SD4 SE Tech because I’m mental
Now greatly regret selling the Outlander. MPG of the FL2 is atrocious and so are the fuel bills. Fun though 😎
Couldn’t afford the fuel bills so back to an older Mitsubishi Outlander PHEV. Significantly better than I remembered it to be…

Bought this solar powered TPMS 2 months ago £20 didn't holdout much hope for it but it's turnout to work really well.

I have a Snooper Tirepilot TMPS that I bought to monitor car and caravan when we went on long European tour 18 months ago.

Now though, the sensors are going faulty. Think it might be corrosion inside them as there is some verdigris to be seen.

Would suggest if you have these external sensor types you consider packing with vaseline or similar to keep damp out. I know they have a seal built in, but every little helps. Wish I had known, and done this.

They are expensive to replace. Andy

Also be aware that the transmitter can leak air so make sure everything is spotlessly clean before putting it on. I did have one very slow leak from this situation.

We are using the external sensors, & when it is screwed on it presses in the valve pin to pressurise the sensor.

If you have an internal sensor maybe you can put on a metal valve cap with bit of rubber or O-ring inside.

Very slow leaks are a pain. Have you put a bit of soapy water on the end of the valve to test for air leaking.

Have you looked extremely closely at the tyre for a screw, they can be very hard to see. Put soapy water over the tyre & see if there are small bubbles. Probably easier to take the wheel off to do this.

I bet there is the remains of a small screw in the tread hiding somewhere. A pair of long nose pliers & a new plug will fix the tyre. Once you have repaired one tyre yourself you won't bother with a garage again. Procrastination, mankind's greatest labour saving device!
