Well had a flat today and couldn’t see anywhere where it could have been punctured. Took it to get a new tyre on and they told me the bead had broken/split and wasn’t a puncture. Now i have to admit i did ride it on the flat for about 200 yards to get it to a suitable spot to change it but the damage was already done, wasn’t repairable. 
They only had a few hundred miles done on them Toyos T1-R's which makes it even worse, had to fork out another £80 for a new one
Now I'm just worried it will happen again, they said they checked the alloy and it was OK, cleaned it up and made sure it was properly sealed so 'shouldn’t' happen again.
Has this happened to anyone? And did you ever find the cause of it?
Cheers
