Everything is relative Graeme. You must be selling a lot of those LLAMS kits.

I recall rationalising that 1 tyre saved would pay for the kit.

From my understanding, within two years a form of TPMS will be required on all new vehicles. Most manufacturers will go the BMW route that uses a combination of the wheel speed sensors and steering wheel angle to determine of a tyre has lost pressure relative to the others based on rolling circumference in a straight line.

TPMS has been the law in the USA for several years and LR fit them to all USA spec vehicles.
I would think the electronics are there and all is needed are the sensors and programming. Has anyone tried to do it the factory way?

On later LR you would need the modules and looms to suit.

I would think LR would not fit anything to a vehicle that they did not have to so as to reduce costs. Mine actually came with the towing bar connection loom missing!! I did wonder why there was no trailer lights. First warranty claim I needed.

I fitted the Safety Dave, Safe-T-Tyre, TPMS two years ago prior to a big lap trip. This is because the D4 factory version was not fitted and according to the manual would only monitor 5 tyres in total. I have a single axle caravan and wanted to monitor 6 tyres as a minimum. The monitor performs well, but takes about five minutes rolling before the receiver/display kicks in. Switching between 4 tyres and 6 tyres on the display is simple and these days I get nervous when driving a car without TPMS.

Initially the TPMS did not pick up the caravan tyres (the main reason I bought it in the first place), but after a call to Safety Dave, they sent a transponder (free of charge) to mount on the caravan and then it worked fine. The only trouble I have had with it was one weird high reading on one occasion. This has not recurred. The button batteries in the tyre units last a year or more and the display plugs into the 12V power socket (cigarette lighter). The transponder is powered by 12V on the caravan. The tyre units screw on as a 'valve cap' and have a tiny hex grub screw to secure (optional) against theft. The tyre units wobble about when on rough roads and scratch the alloy wheels, but that is a small loss when I have the reassurance that the TPMS gives.

I think I'll give the cheap Amazon set a try for $60 bucks and see how they go. If no good, well at least I have a USB charger outlet and a voltage meter. I may even try using the sensors without the locking nut - depending on how long the thread is on my current tyre vales

At this point I don't feel the need to go for an expensive system, if the Amazon one lasts a couple of years at least and are relatively accurate. Suck it and see :-)

I think I will wait a couple of weeks until the 4WD motor show comes to Melbourne and see if there is any thing better on offer their.
