Are my tyres run flat or not?
I've just purchased a second hand bmw x3 from a garage, which doesn't come with a spare tyre, instead it's fitted with run flat tyres. The tyres are pirelli cinturato p7 225/60 r17. I've never had run flats before and the garage assured me that the tyres were run flat. Two people since then have commented that the tyres don't look like run flats, while getting a new tyre for another car today I enquired about the tyres and the guy said that they don't look like run flat. Is there a distinguishing mark on run flats that will tell me. And if they are not what can I do about it?
