My wifes 06 plate cooper convertible has run flats, today driving home the run flat indicator light came on (and it was red) car felt a bit weird. Pulled into a garage and checked all tyres they looked fine!!! checked the pressures and one wheel was lower than the others, but not much. After I restarted the car the light changed from red to yellow/amber then went out. Now having never driven a car with these stupid damn run flats what I want to know is if one of the tyres has suffered a puncture will it be obvious? will I be able to tell which tyre it is, because at the moment they all look fine!!!!!!! What ever happened to the good old days when tyres went flat and could be repaired!!!!!!!!!!

You can't tell if a run flat tire has lost air pressure by looking at it. You need to check the air pressure with gauge.

tbh I had a blow out doing well over a ton and apart from the bang / vibration had no problems, carried on driving fine, so glad I had run flats that day otherwise it would have been a long walk home!

The indicator works off the abs sensors so if you spun the wheels at all or went around alot of corners this can bring it on.you correctly checked the pressures!
