Just put set of four 235-75-15 Trendsetters on a immaculate 69 Continental Mark III. On an afternoon cruise around town, the right front tire blew out, propelling the difficult to replace hubcap into the side of a building. This happened 2 blocks from the point of purchase! The bead separated at the rim. Glad my speed was under 30 mph. It will be interesting to see if Cooper will replace it. Now I'm concerned about the other 3 tires.
