Those Vredesteins are hands-down the best tire I've ever had. I have about 1000 miles on them with the Z06 and they are just incredible. The response to steering inputs is razor sharp; they can actually hold my full-throttle 1st gear acceleration and they perform very well in the rain. The treadwear is much better than on Michelin Pilot Sports or goodyear F1 Supercars, so I expect they'll last a while as well. Also... these tires are much quieter, and at least with a Z06 that is quite welcomed. Less road noise and more engine noise!
