there are no winter tires in 305's. I think people are reading more into this tire thing but maybe I am wrong.
I run my NT05's on my vette all year, I ran the PS2's before that all year, I ran the F1 supercar g1'a all year.
if these G2's are that bad I will just switch to ps2's.
I mean the grip level goes down but you just have to react to it.
