I can get 4 Yoko Avid V4S that are $90ea new for $225 with only 1200 miles (on a lightweight car). I only need 2 for next winter, but should I grab the 4 now? They are great tires, maybe #3 on my list maybe even higher. If I get these, I won't have to drive on rags over the Fall to economise. What to do???
