What Causes Uneven Tire Wear on the Rear Wheels of BMW Cars?
1 Answers
BMW cars experiencing uneven rear tire wear may be due to significant differences in tire pressure, inaccurate four-wheel alignment, or overloading. Significant differences in tire pressure: Large variations in tire pressure among the tires can lead to uneven wear. Tire pressure is critical to tire health; both excessive and insufficient pressure can shorten its lifespan. Inaccurate four-wheel alignment: If the four tires are not aligned according to the standard horizontal and vertical lines, the two wheels on the same side may experience uneven wear during driving. This occurs because the vehicle's self-correction causes abnormal friction and accelerated wear on certain parts of a tire. Toe-in that is too small or too large results in sawtooth-shaped wear on the tire shoulders. Excessive wear on a single tire shoulder with smooth marks indicates excessive or insufficient camber angle. Overloading: Frequent overloading of the vehicle can cause severe tire wear, which is a major factor in accelerated tire deterioration.
