Quick update, popped into kwik fit guy said 30/40 min wait (ended up 25 mins ?) after looking he realised the nail was sitting to close to the side ?, so had to have a new tyre fitted..
All done within an hour…
My Daughter had run flats on here Mini Cooper too, also on a BMW, seemed ok to me, added advantage was she wouldn’t be stuck in the middle of nowhere sorting annoying punctures, giving her time to sort it without being stuck..
Would I have them by choice YES, the roads aren’t exactly a comfortable ride now anyway..
