I’ve ditched the runflats after one of the rears cracked in two places and it’s been welded and had no problems with it for 2 years now. Swapped the runflats to Vredestein Ultrac Vorti and all has been fine till I’ve hit a really bad pothole recently. The welded one kept coming up as an advisory on the MOTs (I guess I should stop going back to the stealers for MOT) and so decided to try and get two decent rears
