Verdict:

As they were two-ply with a load rating of 112T, we expected the Coopers to do quite well, but their rigid LT (Light Truck) construction sidewalls did not help their cause. They impressed with their stability and stopping power on tar, but their traction on gravel and in sand was limited, possibly due to too high pressures.
