This 'little' bulge appeared 4 days after the Angry Doctor, while the bike was simply on its rack.

Seems to be quite a few Maxxis tires (not sure if it's isolated to Crossmarks - which are my favourite tires) with these little bulges appearing (mid ride), therefore rendering the tyre useless...

Not sure exactly how many ppl had had the same problem, but would be keen to write to Maxxis and ask "What's up?"...
