@ Chuck - so, is that means Conti is not good? I am really looking forward to have the same Michelins as replacement but was told by Costco, the manufacturer told them, it'll take approx. 5 weeks, Tire Rack had it available on 03/10/2010, same thing with America's Tire. My existing tires (rear) had below the marker tread already.
