Thread: TPMS

I'd be interested in:
In tyre modules measuring both pressure & temperature.
iPhone or Android monitoring.

Something like this:
Orange Electronic P418 TPMS Pressure Monitoring System Apple Iphone Ipad Black | eBay

Anyone got / had one?

Hi Ian, I also have LMS system, I tow a 9m van, no problems with picking up all the sensors even from the front seat. The system is expandable and reasonable easy to use, has some good features like being able to "drop" the van monitoring when we go somewhere in the D4......but.... the sensors are quite large and because they extend out past the wheel rim they flex on the valve stem and hit the rim. Before I realised it the sensors had damaged all 8 wheels, a small pad of self adhesive foam on the rim fixed the problem, but there it is. Also because they protrude outside of the wheel rim, not ideal for off road work, no issues of valve stem damage from that respect so far but something to consider.
The learning curve from cold inflation pressures to hot pressures was interesting, and given that learning curve I would definitely go for a system that monitors temp as well as pressure next time, which probably means an internal system.

I'm running Tyredog with six sensors and have just completed a MEL to PER run towing a camper trailer. Two sensors on the trailer. The external sensor has been fine so far, and is accurate as I've measured the pressures with a gauge both cold and hot. It also has temp.

The downside so far is that because of my relay location, the left rear camper sensor is not picked up. However you wouldn't know that it's not being picked up because the display indicates all is okay. The main fault with the Tyredog for mine therefore is that it doesn't tell you when the sensors have stopped communicating with the relay. This can leave you thinking you are monitoring when you are not.

I have Tyre Dog too. I like them compared with the in tyre versions because I have 6 @ 19in road wheels and 6 @ 18in GOE off road wheels and various trailers. It is very easy to move them to which ever wheels I am using.


If a sensor loses contact with the relay the display reports that by showing the tyre symbol as empty. When starting off each tyre "reports in" and the empty changes to normal. I do not have the issue that BSM describes. My system is about 5 months old. (I replaced a very inferior and no longer available TPMS system in December)

I'm pleased to hear that Fred. I bought the cheaper Taiwanese Tyredog from e-bay, which I note is a different model number to the one sold in Australia, although the e-Bay vendor claims they are identical.

By the way, where have you mounted your relay?. I mounted mine under the vehicle on the drivers side, attached to the chassis rail with a captive nut, it's rougly in the middle of the rear door sill on the opposite side to the compressor.

I wanted to mount it further aft and located more centrally, but just couldn't find a good spot.

You may not like this BSM , but I was planning to put the relay under the car too. I ran out of time and so put it in the driver's side rear cubby hole/box. The one next to the third row seat position. It works perfectly including to receive from trailers. It is easily accessible to replace batteries too. I have decided to leave it there.

I'm waiting on my Trailair to arrive

Hi Peter,


Very interesting comments. I was thinking of the LMS system as it seems to be robust and well reviewed (4WD Touring Magazine). Your comment about protruding from the rim and not suitable for four wheel driving is a concern.


Cheers Ian
