2004 CTS (sold), 2014 ATS
I can't go through another winter on the stock RS-As so I'm looking for winter tires. WalMart has Dunlop Graspics, size 215/55R16, that'll run about C$450 for the set plus tax. By the description, they seem similar to Blizzaks in that once the treads get halfway worn the compound changes and they become more like an all season tire. Anyone know if these tires are any good?
