Technician A says that camber used to be a heavy tire-wearing angle when tires were the bias-ply type and had stiff sidewalls. Technician B says tires can tolerate huge amounts of improper camber much better than before. Who is correct? Select one: a. Technician A b. Technician B c. Both Technician A and Technician B d. Neither Technician A nor Technician B

## Step 1<br />The problem involves understanding the concept of camber in the context of tire wear. Camber is the angle between the vertical line from the center of the tire and the ground. It can be positive (when the top of the tire is leaning outwards) or negative (when the top of the tire is leaning inwards).<br /><br />## Step 2<br />Technician A's statement is that camber used to be a heavy tire-wearing angle when tires were the bias-ply type and had stiff sidewalls. This statement is correct. Bias-ply tires, which have a crisscross pattern of plies, were more prone to wear when the camber was not properly aligned. This is because the stiff sidewalls of these tires would not flex as much, leading to increased wear.<br /><br />## Step 3<br />Technician B's statement is that tires can tolerate huge amounts of improper camber much better than before. This statement is also correct. Modern tires, especially those with radial construction, are more tolerant of camber variations. This is because the flexible sidewalls of radial tires can accommodate more camber changes without causing excessive wear.
