....So, no probs in the wet?
They're supposed to be pretty good in the wet too, leaving other tyres "in their wake " according to EVO

Coming a highly comendable 2nd place in this years EVO tyre tests scoring an overall 95.3%, the Ultrac Sessanta was the choice of both EVO testers, Jethro Bovingdon and John Barker, on the road being praised for their absorbent, quiet ride and smooth, nicely detailed steering.
From EVO's wet handling test
'it was the Vredestein Ultrac Sessanta that proved the tester's favourite. "Superb," said Bovingdon. "Heavy steering but backed up by strong turn-in and the ability to give more bite if you need it. Very good traction"'
From EVO's aquaplane testing
'In the straight line test, the majority of the tyres are within 5% of the Dunlop's performance, but on the wetted curve the spread is much higher, though this is largely due to an exceptional performance from the Vredestein. A star performer in the wet handling tests, the 'Giugiaro Design' Ultrac Sessanta leaves the rest in it's wake, the Bridgestone being the best of the rest some 17% down."
