This is original tire on my Platinum. I do tow a heavy 8,000 lb. boat and trailer occasionally with several high mountain passes in Montana and Idaho. Also drive same roads in severe winter weather. Basic complaint is noticeable treadware at 24000 miles. I'm a maintenance freak and the tires are regularly checked for pressure and rotation. I'm probably going back to Michelins in less than 5000 more miles!
