I have the G8 Gt with the "Summer Only" PKG and live in Eastern KY. I have been reading that once it gets to 30 degrees or below that these are not going to work well. Anyone had winter experience with these tires yet? If I do need to get an all season, what is the best suggestion for the 19" rims I have as if I need to get the better tires, I may just buy a new set of rims for my summer use and put the Summer only tires on those and just change them with the seasons.
