I have had Chinese Marathons and Carlyles delaminate on 3 of 3 tires [spare too] and all blow within 400 miles of each other. My tire guy says a lot of the overloaded lawn service trailers run the Maxxis ST tires so I pulled all of my others off and went to the Maxxis. All of the Chinese tires are junk no matter what brand name is on them.
