Effects of Tread Pattern on the Surface Traction of Terra-Tires

The study consisted of two test series conducted using seven Terra- tires, of which one has a smooth surface and the other six had various tread areas and patterns. The first series was to determine what effect adding tread to the Terra-tires on the MTV would have on its slope-climbing and pull- producing ability. Tests were conducted on a strong fat clay with a wet surface, and each test consisted of five passes with a single wheel powered at 20 percent slip, or locked in a full skid. The second series evaluated four materials for possible use in sponson construction. These tests were conducted with the same seven Terra-tires on both wet and dry surfaces of each material. The wheel was either free rolling or locked.
