Al, Both brands have been known to have separation problems. It's a toss up when it comes to defects for any brand. ME880's like to throw chunks of tread off them on rare occasions. I think it boils down to high mileage (ME880's) or bettter grip and not as much mileage (BT020's). I personnaly have ran both and others have tried many brands. I just love the feel and handling of the BT020 radial tire.
looking around for a possible replacement
