That's why they are band new ;)
I work at a Tires Plus store. I bought the Blizzaks on sale this last spring because they introduced the new WS-60's. However the car has never seen a snow fall.
The first owned lived in Southern Iowa and the cars was driven vary little and stored in winters. I bought it last fall, drove it for two months and then stored it on jack stands all winter. I Sold my winter beater this year being tired of driving a nice car only half the rear. Before I had to drive it in the winter, I figured sell it to someone who could store it. Or someone who wanted to drive it year round (MR makes for good traction).
