Hi guys, had the front passenger side tyre blow out today on the m54 while travelling at 'motorway speeds'. The tyres are only 3 months old, Pirelli Pz rosso 235 40 18's. Having taken it off I found the tread had peeled away from the sidewall around half of the tyre diameter, is this likely to be wheel alignment or a duff tyre ? also had the fun of discovering the audi/vw space saver that audi flogged me won't fit over the brakes. Happy times!
