I had the Marathon Plus on an eGlide bike. I'm not very hard on tires and always ride on paved roads or bike trails. The back tire is still ok after about 1,700 miles with a lot of thread left, but the front tire had the side wall burst even though it still had a lot of thread left at about 1,000 miles. It could very well just be a bad tire from one particular batch, I'm sure it happens to every manufacturer, but given how expensive they are I won't be buying any more Marathon Plus tires.
