See illustration 3. Camber evenly distributes the truck's load across the two wheel bearings and assists in keeping the truck from drifting slightly when tracked in a straight line. Insufficient or excessive camber shifts the load to one edge of the tire resulting in excessive shoulder wear. Inc. Excessive unequal camber will cause the truck to pull toward one side. To keep the truck on path, the driver will have to compensate by turning the wheel.
Some manufacturers recommend a small camber difference to compensate for crowned roads.
Study the illustrations below for typical tire wear problems. Notice how each wear pattern is different from each other. Locate any truck larger than one ton and request permission to visually inspect the front tires for improper tread wear. Compare the answers to the questions and the condition of the tires. Write a summary of your recommendation.
