You are correct Bruce. Marabomb failures are usually due to belts failing not sidewall failure. Art, I believe the best chance to get life out of the Marathons is to avoid twisting them too much. GoodYear has determined that that is where the majority of the belt failures they have looked at came from. I never abused mine, but I did have to park it in some tight spots. My belts broke in two tires. I always kept them at 80 PSI, and yes I did get over 65 MPH some.
