What Causes Uneven Tire Wear on One Side of the Truck's Front Wheels?

[JuliaLynn]

Truck front wheels experiencing uneven tire wear on one side is primarily due to inaccurate wheel alignment, which includes four key parameters: caster angle, kingpin inclination, camber angle, and toe angle. Any abnormality in these parameters can lead to uneven tire wear. Below are specific causes and solutions: Specific Causes: Steering gear malfunction can also cause uneven tire wear and may even lead to vehicle deviation; uneven or deformed chassis can result in uneven tire wear, a common issue in some accident-damaged vehicles; mixing tires of different specifications can cause uneven wear if the four wheels cannot operate harmoniously in a stable environment; aggressive acceleration, sharp turns, and sudden braking can also contribute to uneven tire wear. Solutions: Uneven tire wear on truck front wheels can be addressed by adjusting the camber angle and toe angle. Adjusting the camber angle can be achieved by inspecting and adjusting the wheel hub bearings, where the tightness of the bearings can be modified to alter the camber angle. For front wheels with independent suspension, the camber angle can be adjusted by adding or removing shims between the upper control arm shaft and the fixed bracket.
