Both my summer tires and winter tires are shot. I found two great deals on winter tires. One size is 195/60/15 (I have 15" steels for winter) $250 for all 4 with 1000 miles on them. The other size is 225/50/16. The 16" tires are so cheap $95 for all 4 (they have 6000 miles on them) I could probably have them mounted/dismounted once and still break even. Which would you choose? or neither?
