What does that mean? The only thing I have heard about them is that they wear fast but I have no first or second hand experience. I am due for a tire right now and would love to pick this up at the price but afraid of wasting my money. I only got a little over 5k on the stocker so hoping to get more out of my next tire.///Matt said:Shinko's are great.... as long as you don't ever turn hard, or brake hard.
