New car (2months), bmw335xi (excellent), delivered by BMW france with 4 runflat 18' 225/45 Goodyear (in france the client cannot choose the trade mark of the tyres during ordering). After only 4500 kms, bubbles on the external wall of the tyres (anterior and posterior right). One week later (strict speed limitation to 80 km/H), bubble and external injury on the external wall of the left anterior tyre. No shock, no whole on the road, no impact on wheels but spontaneous bubbles. No perception when driving, no signal of dysfunction on the electronic board until the left tire rise down the pressure and was definitely out of order. 3 out of 4 tyres out of order on a new car (<2 months) after only 4500 kms!!!! this is the reverse of technical progress. This is a very severe and serious problem with safety consequences that engage life of BMW clients. This canot be attributed to BMW but to either tyre manufacturer or agencies dvoted to tyre homologations.
