From Bridgestone website... "Less grooves on the tread edge allow for better dry grip and machine control in corners, and more grooves in the centre area leads to better wet performance."
As you can see from the pic as well, it's a cracking tyre in the dry, but no tread near the edges for the wet.
Just want to point that out. I'm not against them, they're just a nightmare in the wet.
It may not rain of course, but then this is Britain!
