I was drving home yesterday, and the tyre warining came on on the dashboard. Immediately think great £150 etc. But I dont think I have a puncture. I was changing lanes approaching a roundabout, and their was a slight camber between the two lanes, and i have read in my manual that this could cause it to trigger. Because the way it works is it monitors the speed of all the wheels, and if one slows down it says you have a puncture. Anyway I have reset and done over 30 miles since and the light after I reset has remained off.

My concern is that you cannot tell you have a puncture with RFT, is their anything else I can check bar looking at the pressures, which if one is 2 bar down paranoid me will think it has a puncture?

Cheers

Lol, 2 bar is definately a puncture. If it's 2 psi, then pump it up to the correct level, and do the same with the others and see if it loses pressure at the same rate as the others. If it's losing it much quicker you probably have a puncture - this however may be repairable.

Sorry it was a matter of speech. I have not looked at them incase one is slightly low and I get paranoid.

now that is just asking for trouble...idiot

No I would be an idiot if the light has come back on, no need for a sarky response like that mr! The car is new to me with the first time of using RFT, non of them look flat. The reason I have not used an air line is, because air does slowly seep though the tyre walls, so if it was down a couple say 30 instead of 32 that would make me think its a puncture paranoid as that may seem.

So Bullit any thing constructive to say as to how to test a RFT for a puncture just to make sure because the light has remained off.

Nothing to add then click back on your browser please ;)

Doesn't have to be a puncture - could just be the tyre not seated properly on the rim, leaking a little air.

But the light would come back on right? Reading the manual you have to disable the system when using snow chains etc, because of slip. The light would have come back on withing the 50 miles I have done now since it happened right?
 
Sorry, to drag this out, but what I am trying to explain. It can sometimes be enabled if the wheels slip, cambers etc this is what it says in the manual. I just want to know that if I have reset the warning, if I did have a puncture then surely the light would come back on right? I will take it to the garrage tonight and pump them up, I just think its pretty crap you cannot visually see if you have a puncture. How many people have had the airbag flash on, only to be a faulty sensor? I am thinking it is a rogue case.

Parents mini does it quite a lot. Quick reset using the reset button on the handbrake surround soon puts the light out. The fact there is a button for it suggests it happens a lot.

Thank you Simon, this is what I thought.

Cheers
