I have the General Ameri G4S tired and those tires can grip in the snow. I put 17K on those tired going on a year and they still have about 60% tread left. The treadwear rating is 520?? I think. like the guy said in the previous posts stay away from Firestone Firehawk GTA tires. They wear down too quickly. and they have a low treadwear rating 300.
