Run flat tyres

I've heard of this system giving false warnings.

If you check the pressure with a normal tyre guage you'll know which one is the problem.

In the UK most places can repair them as long as it's not near the sidewall.

If it is a false wanning, which it is quite likely to be, you need to set this electronic self monitoring gauge properly. Make sure you have inflated the tyres evenly and according to specs (cold tyre specs). Then before you drive off (preferably in the morning), re-set the gauge through the car computer. This gauge measures the change in the air pressure relative to where you set it and if the person you bought it from had mis-set it i.e., at too high a pressure, you will get a false warning even if the tyre pressure is only relatively low. This can happen just over time or if you were to hit a curb hard.

FWIW it's no longer BS approved to repair the high(est) performance tyres although I'm sure most places will still do it provided there's no hint of sidewall damage.

You city folk are so quant. You can buy a tire repair kit almost anywhere. That, a bottle of soapy water in the trunk and a pump that plugs into the lighter and you can repair it yourself.

Many thanks for the replies. Just been to the local garage and the tyres were over inflated ! I have set them as per my driving prefs and reset the computer and all seems well. All the tyres were inflated so presume no puncture but will get them checked over the next day or so. Regards David

~It does NOT measure tyre pressures - it measure the effect of tyre pressure change which results in change in rotational speed (the principal that a bigger circumference rotates slower to cover the same distance as a smaller one). It measures sustained change in turn ratio between tyres through ABS sensors by detecting rotational difference.
