Reasons for Uneven Wear on the Inner Side of Rear Tires
1 Answers
The main reason for uneven wear on the inner side of rear tires is the misalignment of the front and rear axles, where the wheelbase on the right side is larger than that on the left, exceeding the standard. Misalignment of front and rear axles, exceeding the standard: Wheelbase standard (measured at the spring seat of the front and rear axles) maximum left-right difference is 4mm. Solutions: For leaf spring vehicles, the issue can be resolved by selecting and adjusting the length of the leaf springs. For air suspension vehicles, adjust the length of the thrust rods. Causes of tire wear: Tire wear is mainly caused by the friction generated between the tire and the ground during sliding. Constantly changing driving conditions such as vehicle start-up, turning, and braking, as well as excessive turning speed, abrupt starts, and harsh braking, accelerate tire wear. Measures to prevent tire wear: Pay attention to tire pressure, as it is critical to tire life—both too high and too low pressure can shorten its lifespan. Regularly check the front wheel alignment and be mindful of driving habits.
