Not sure how much my x 2 multi vehicle units cost now, but have been very happy with both for towing van and trailer/s. I think I paid about $250 for each.

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?

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 got this cheapy, it works pretty well. Solar Wireless Car TPMS Tyre Tire Pressure LCD Monitor Alarm &4 External Sensors Solar Wireless Car TPMS Tyre Tire Pressure LCD Monitor Alarm &4 External Sensors 753807578752 | eBay
