Thread: TPMS Question

I can't answer your questions other than that you can easily purchase te sensors online (plenty of OE ones on ebay) and that the D4 has the antenna for each sensor behind the wheel arch liner, so very short distance for signal transmission - I am guessing this is so you can put any wheel on any position and get correct sensor location readout. I therefore would not expect it to support trailer TPMS

I had TPMS sensors on my D3 - 18" wheels with Pirelli Scorpions as well as couple on the camper trailer we towed.

When I got the D4 I took the sensors off the D3 and put them onto the D4 wheels - 20" alloys with Cooper Zeons and no dramas.

The sensors are only on the wheels to relay tyre pressure and temperature; it shouldn't matter what size the wheel / tyre is.

I also bought a couple more so that now I have four sensors to put on each wheel / tyre of our tandem caravan.

We've just driven from the NSW south coast to Darwin, no probs at all apart from one sensor which is in the habit of 'chewing' batteries. This one's had six replacements (right rear) whereas only one other unit has required a new battery.

I reckon a TPMS should be one of the first things people should buy, especially if they're doing any off-road work; the electronics in the D3 / D4 / RRS, etc are just too good. We were on the Tanami a couple of years ago (2014) and had a tyre disintegrate, it went flat, got too hot and literally 'exploded' and I had no idea the tyre was even flat because the car's systems compensated.

So, with tubber at $400 and more a corner a TPMS, I believe, is great insurance.
