I ran 28 and 29x9 good/years and 28x9 m/t on my dart 3000 lbs 1.41 60' with either brand the side walls gave out long before the tread I could get 200 passes out of the m/t before they were junk the good years were only good for 125 to 150 but may have been a bit more consistent for the first 50 passes
