I much prefer pulling the tanks with 22.5 truck tires, both on the road and in the fiels, compared to the 12.5Lx15's. Truck tires are taller and almost as wide and pull much easier in soft soil. Also no speed limitations and are radials so I don't think they compact as much. Less tire trouble on the road. All around better. If two tanks are sitting side by side full I will always hook up to the one with the 22.5's first over one with 11L or 12.5l's.
