Not had these myself but have been in cars with them.
I've had F1, T1R T1S, Uni rainsports, sportrac 3's etc, now on HANCOOK V12 VENTUS EVO, makes the F1 looks like the shitty tyre it really is compared with the hype about it.
NO way will I change from Hancooks, would very happily pay 3 times the price of F1's for the Hancooks, simply light years ahead, and yes I do push it even in the wet, a point to note about tyres is most are using SUMMER tyres, the reason they don't work well below 7C is because of the material it gets hard, the Hancooks are not like this temps don't affect it, I didn't know this till talking to a tyre tech person.
