A guy up the street with an '03 returned from a round trip San Diego to Honduras and back pulling an 8,500# trailer. No rotations,no rebalance or flats. At one point,he had to drop the pressure to 8# to get out of a bog down there. He's got 22,000 on his 35-12. 50-17's. They'll easily make it to 35,000 safe miles,and those are tough miles,pulling,with no maintenance. For a tire that size,next to no lead balancing the suckers.Make sure you are happy with 20,000 mile tread life before you pull the lever on these guys.
