"Over-the-highway truck drivers can gain a fuel consumption 'bonus' simply by using less throttle," says Tim Miller, marketing and communications manager for Goodyear Commercial Tires.

Tests show that fuel consumption increases by 0.1 miles per gallon for every mile-per-hour increase in speed over 55.
