What compound are they. All slicks will 'roll' on the edges and form marbles when they get hot, its what they do. Is that what your calling bleb ?
they were S2A ( I have S4A on the front) and yes I think it was hot it was last year when I got the info and can't remember(haven't checked them since

I I remeber he gave me a "ball park figure" of 25-27 psi
I will post a pic of the bleb, tomoz it is about 6 inches accross and half way round the tyres!
