Hi, Tom here from the Detroit area. We bought a 2011 Explorer Limited from a local dealer back in April which I enjoy so far. It came with snow tires on it which I neglected to notice until I got a flat on one and my local Discount tire told me that's what I had. I always wondered why the tires were noisy especially coming to a stop! Oh well now I have a nice set of snow tires to use in the winter time. Thanks all!
