Quizplus · Accepted Answer

Both Technician A and Technician B are correct. The objective of a toe specification in commercial truck steering systems is indeed to achieve zero toe when the truck is fully loaded and running at highway speeds, as this helps in reducing tire wear and improving fuel efficiency. When setting toe on the shop floor, especially for trucks equipped with radial tires, it is common practice to set it at zero or with a slight toe-in to compensate for the slight toe-out that occurs as the vehicle starts moving, ensuring optimal alignment during operation.
