I have just seen an ad. for Tyrealert, has anyone used a tyre pressure monitoring system?

Are they worth having?

Never used one but have order it on my new Octy, as it is the one thing that I rarely check, and I know I should. Plus with Power Stering these days it is not so easy to tell if the tyre is slightly deflated.

Think they are a good idea personally.

I haven't tried that one, but I know the ones fitted to the 5 Renault Lagunas we used to run in the company gave us nothing but grief! Good idea, but for some reason, poorly implemented. (In my humble opinion etc)

A m8 has this fitted to his laguna and worked fine. He almost cried when Renault told him it would be

I had them on my old Megane. Apart from one cold morning when the FOS light started to flash to tell me the tyre needed topping up, I never made any use of them. I didn't have it long enough to change the tyres to find out if it would have been mega-expensive, though. I assumed that the sensor was on the valve only, and worked on an induction principle off the unit in the car, and hence was independent of any other part of the car. That's just a guess though. :confused:

Apparently all new cars sold in the US have to have some sort of tyre pressure gauge or warning system after the whole Ford Explorer / Bridgestone tyres thing. IMHO, it represents a lot of what's wrong in the world today that manufacturers are made responsible for protecting a minority of car owners against their own incompetence / laziness...
