Tpms damage

I guess it depends on the valve stem length and rim design.
I purchased some for a trip to Cape York this year, probably done 10 000km so far with them including approx 2000km of dirt/gravel with no major markings on my rims.

Some previous threads about this problem talk about using shorter valve stems and/ or drilling a valve stem sized whole through a champagne cork diameter length of rubber/neroprene to hold the valve stem (and therefore monitor) away from the rim.

Do a thread search on TPMS and you will find the details

Rich, I have been told that if you fit metal valve stems it stops the stem and sensor flexing and hitting the rim, causing damage to the rim and sensor. I haven't fitted my TPMS yet............

I had similar problem, also the occasional sender dropping out - fitted steel valve stems and not a problem since. No More rim marking and no sensor drop-outs.

I had the same problem and cut some approx. 30mm squares out of some 2mm rubber sheet I had, punched a hole through the valve stem size, pushed them over the valve and refitted the senders and all fixed.
Just done a trip up the Gary and Talawana with horrendous corrugations plus some hwy running and they're working well.
Cheap easy fix.

Thanks all to replies

I have internal ones now but when used external ones I just put a bit of heat shrink over the stem and sender
Worked fine

As suggested I got some of the insulation tubing from burnings which slips over the valve stem and even the bottom part of the sensor

Hi Rich

I use Doran 360 and have been on the vehicle for 60,000 kilometres without any noticeable marking on the rims.

I use rubber stems, but as others have said you can use steel stems.

And as a further note, the Doran 360 is a brilliant system, has never failed me at all.

Morning all

Just looked at the Doran 360 system. Haven't got a price yet but that can wait. While solo time is not really an issue. In convoy it may irritate some. I don't like to irritate anyone at any time and also am curious about a change in pressure programming duration.

Over the period of one plus a bit days during the last Simpson trip we went from 35 to 25 to 20 and then to 16 PSI. If I had a TPMS system that would mean three changes of the programming. That was Oodna - Mt Dare - Old Andado and the first big dune.

When leaving the Madigan we went up to 20 PSI for the QAA line and back to 16 for Big Red (I tried just a slow drive up at this pressure and all good with the car weighing 3500Kg). And then back to 35 after Big Red.

I have no idea how long each change of pressure programming would take. Solo - no hassles. Travelling in convoy - do you think we would hold up the rest?

What would you educated peoples reckon? How long to program a change in tyre pressure stop?
