Results were obtained from tests to determine the effects of variable tire pressure on hauling-vehicle tires. Tests address two major categories--tire wear rates and tire carcass life. Results indicate that the larger ground contact area of reduced tire pressure operation, in an off-highway condition, is not detrimental to tire wear, and may be beneficial to tire wear on rough roads where energy is wasted because of a vehicle's bounce or hop. Testing performed to dateindicates no detrimental effects on tire carcass life, but it is deemed too early to make conclusive statements on the basis of the tests presented.
