4500 miles total and the side wall failed on the way back from minnesota in the HEART of battle mountain,nevada, however this time the tire shop I bought them from here in California is going to replace it. thank the dear Lord that I took my floor jack with me. all brand new, mounted and carefully balanced, checked pressures each morning, 61 miles per hour on a new section of roadway, saw two other trailered boats with similar problems, one had carlyles, the other was wearing firestones.One was in Montana, the other was in Idaho.
