My Z will probably never see snow
If I lived in those condition my sports car of choice would probably be WRX STI, or maybe I would just have both, and store the Z away in the winter
I will say though, It has been raining here in Cali a lot lately, the Hankook Ventus V12 tires are excellent in wet conditions, probably not for snow though, but virtually no hydroplaning or sliding out compared to the Nitto NT55 on my Mini and the stock Bridgestones.
