These tires were installed on a van that we only drive while on vacation. They have less than 4,000 miles on them, and the back two tires failed over the weekend. When our van started vibrating violently, we took it in for repairs. The mechanic advised (and showed) us the center belt separation on both back tires. I have spent most of the afternoon researching the tires, and there are numerous complaints about belt separation. The tires appear to have no warranty. The manufacturer is in China and has no email address. You have no recourse if your tires fail. Don't buy them.
