I don't think its wireless.

It is with some of them.

If it's not wireless what could it possibly be?Â* ESP?


Tyre rotation based usually via the ABS sensors. Not really "pressure"
but more "your tyre's completely shagged".

That's the most basic version.

The "better" versions use low-powered, battery transmitters. Which of

etc. One not working will now be an MOT failure, so that'll be a nice
little earner for the dealers.
