I just bought my first chains this year. Before buying I called the seller of these chains and discussed the required clearance for the chains I was purchasing. He said I needed 2 3/4" clearance between the tire and fender. These chains fit with a 1/4" to spare. The chains are expensive. The shipping costs are very expensive ($150.00). A phone call and a few minutes talking to an expert made this a very pleasant buying experience for me.
