don't want to poke the fire (too much) but I have just come across some pretty negative stuff regarding a certain brand of tyres when looking for some info on the GS..

Understand that this could be unsubstantiated internet opinion but if it is true….

I spoke to a couple of people in the trade regarding these and apparently the sports touring tyres are getting very good feedback from customers.

However, the full blown sports tyres have been causing problems. Both dealers have had a number of pairs returned with the same fault. When the tyres heat up the tread appears to lift away from the carcass of the tyre as if delaminating.
The tyres are fine when they cool back down again and there haven't been any total failures.
The official explaination is that air has become trapped in between the tread and carcass during production and that it isn't really a problem.
Still don't think I would bother.
