What Causes Uneven Tire Wear on Trucks?

[OWillow]

The causes of uneven tire wear on trucks are as follows: 1. Incorrect wheel alignment causes the four tires to deviate from the standard horizontal and vertical straight lines. This leads to uneven wear on the same side tires as they roll, or the front/rear wheels not tracking straight, forcing the vehicle to self-correct. This results in abnormal friction and accelerated wear on specific parts of certain tires. 2. Inaccurate toe adjustment can also cause uneven wear. Toe refers to the slight inward tilt of front wheels (similar to pigeon-toed stance), which is the optimal angle for high-speed stability. All vehicles have a toe angle, and improper adjustment leads to uneven wear, similar to the first point. 3. Uneven or deformed chassis frame can cause uneven wear. For example, some accident vehicles experience uneven tire wear due to chassis/body deformation.
