Regarding 2.5 degrees of cross camber, Technician A says it could cause tire wear and Technician B says it could cause a pull. Who is correct?

Cross camber refers to the difference in camber angle between the left and right wheels of a vehicle. A measurement of 2.5 degrees indicates a notable disparity that can certainly impact vehicle handling and tire performance.

The first technician's statement about tire wear is accurate because uneven camber angles can lead to one tire wearing more rapidly than the other due to uneven contact with the road surface. Tires with different camber angles will have differing wear patterns, which can compromise their lifespan and effectiveness.

The second technician's assertion about causing a pull is also valid. When one wheel has a greater camber angle than the other, it can lead to differences in how the tires grip the road, causing the vehicle to pull towards the side with less positive camber. This misalignment can affect steering response and vehicle control.

Thus, both technicians are correct since cross camber can result in both increased tire wear and a pulling sensation during driving, which illustrates the importance of proper wheel alignment in maintaining vehicle performance and safety.
