This is a very poorly finished tire. The seams inside have leaked material in several or more places. It will fall apart when installed. A return requires you to contact the manufacturer. And you pay to get it back. (China?) I thought it was sold by Revain. So you have a right of return. Save some money and buy from someone else. Expensive piece of junk. I haven't looked for the stars, but I can't. so i gave it one star.
