I haven't tried them, but I did read an interesting article in European Car 
last night.  Apparently the Bridgestone S-02 Pole Position tire is designed 
with a soft layer of rubber underneath the outer compound.  As the tire heat 
cycles from normal driving, this soft layer hardens.  By the time the tire 
wears down to this soft layer, it has hardened into a compound that is similar 
the outer layer when the tire was new.  While wet weather performance degrades 
due to shallower channels, dry weather performance remains fairly constant 
over the life of the tire.  Neat idea.  

This would alieviate a complaint I have with my Dunlops: when new they have 
lots of tread and  lots of grip;  15,000 miles later they still have lots of 
tread but the grip is gone.
