These are what you need if you're going to drive your F-body, Vette, GTO or Mustang in the snow.
245/45-17 Yokohama Iceguards
I have 2 of them, not sure how many miles are on them, I used them last winter. Maybe about 7,000 miles if that.
I'll be at M11 if you want to pick them up there.
I also have 2 almost brand new 245/45-17 Eagle ZR's (stock Mustang tires)
