Thread: external TPMS for D4

I've had the ARB one for about 18 months which looks very similar to your link, but was a lot more expensive. Anyway, it works perfectly and alerted me to a slow puncture leak before any damage was done.
As part of your normal driving routine of periodically checking your instruments, you soon learn to also glance down at the TPMS display. Any discrepancy is obvious.

A good brand... Doran. Designed for the mining and trucking industry. So you pay for quality. Screw on. No locking nut you need to remove each time you air up or down. Haven’t lost one in the past 4 years. Sealed. Therefore you have to replace the sensor when flat. But no chance of water ingress. Connect and disconnect trailer with sensors. I just wished it had stored settings for on road and off-road.

I use a solar powered unit from dig options. They advertise on eBay. No need for wires cables to cig lighter sockets. Mine also reads the caravan tyres (6 wheels all up)

Hi

I got the Safe-T-Tyre ones from Safety Dave. I had a look at about 3 others at the Caravan & Camping show this year. I picked these as the display and the font size is big enough to see, the batteries in them are replaceable, I can buy extra transmitters individually. I have it mounted on the far passenger side as I have other stuff on the drivers side.

Other brands show all 4 tyres at once in colour with a small colour display. I did like the colour display with green OK, red bad. The Safe-T-Tyre ones cycle though the tyres every 5 seconds and is black/white.

Check if you can buy more sensors as some other brands require you to buy a set of 4! or you can't change the battery in them so you throw them out after a couple of years and buy more.

TPMS are so good. They should be required on all vehicles.

I just purchased Pressure Pro from Tyre Safe...packed with a few nice features.

Although price is at the other end of the scale.

Hi SeanC,

As I don't have any experience with external TPMS, when you say you have to remove the locking nut with other brands, is this because a tyre gauge, tire deflator or tyre inflator won't fit on the end of the tyre valve with the locking nut on, or is this because you have to loosen the locking nut each time to get the end of the external sensor cap off ? Do you always have to use the locking nut, or do you risk the sensor flying off the wheel ?

Mine's locking nuts are supposedly for security rather than required to prevent the sensor from unscrewing.

My locking nuts have to be removed from the current stems to use my gauge or pump because the thread is too short but could remain on the previous stems. The nuts also run off the inner end of the stem thread - another shortcoming of what I consider to be inferior stems fitted when my current tyres were fitted. i'll endeavour to have better quality stems fitted next time.

Some sensors have a locking mechanism to stop them coming loose or being stolen. Which means you have a tool to to remove and replace them each time you air down and up. I think I would find that annoying. It’s just easier to unscrew like a valve cap. Mine have never fallen off or been stolen.
