I had the rear tyre blow out on Wednesday on a dual carriageway, every one assumed it was a puncture (two garages I called) but I could see no visible entry, it went down so fast that it'd definitely have left a mark at least. AA came out and tried to get it inflated but couldn't, air was pi$$ing out between the rim and the tyre in one spot. He tried a few things to try and get it to seal back on but it wouldn't. I got recovered back to the garage it was fitted at the start of May (literally just worn in). They said they couldn't look at it that day so I got a lift home. Later in the day I got a call saying the bike was done and the tyre had been replaced. Apparently there was a manufacturing fault of some kind and they were sending it back to Bridgestone. I guess I'm posting mainly out of interest to see how often 'faulty tyres' are seen? It's not confidence inspiring to have tyres blow out like that, I'm just glad it happened going in a straight line!
A few years back I'd had some Pilot 2CTs fitted and a couple of days later I'd had a voicemail left by the fitter telling not to use the bike under any circumstances. Turns out that a whole run of tyres from the factory in Spain were delaminating. They had to wait for another run to come off the french factory to replace them all. Moisture in the manufacturing process apparently.
