Flat Spotting Wear – Localized wear across the tread width. Causes include brake lock, brake imbalance, out of round brake drums, axle hop, or skip. A tire being parked on a surface containing hydrocarbon oils, chemicals, and solvents can also cause this type of wear pattern. The affected area of the tread will wear more rapidly, leaving a flat spot. Diagonal Wear – Localized wear diagonally across the tread width. Side forces imposed by a combination of toe and camber create diagonal stress in the footprint of the tire. Localized wear patterns tend to follow this same direction creating diagonal wear. For steer positions, causes include excessive toe combined with tandem drive axle misalignment, incorrect steering angle in turns, worn parts, and/or excessive camber setting. For trailer positions, causes include tandem trailer misalignment, negative camber, and loose or worn components.
