What Sound Does Tire Cupping Make?

[AliviaLynn]

Tire cupping usually produces a humming sound when it becomes severe. When there is an issue with the wheel bearings, it can also cause a humming noise, which tends to get louder as the vehicle speed increases. Causes of tire cupping: Four-wheel alignment data: Inaccurate four-wheel alignment data. If the four tires are not aligned on the standard horizontal and vertical lines, the two tires on the same side will experience cupping while driving. This happens because the vehicle self-corrects, causing abnormal friction on a specific part of a tire, leading to cupping. Frame flatness: An uneven or deformed frame. This condition causes uneven tire pressure distribution, leading to cupping. It often occurs in vehicles involved in accidents. Tire pressure level: Overinflation or underinflation of tires. Overinflation accelerates wear on the center of the tire while the sides remain normal. Underinflation accelerates wear on the sides of the tire while the center remains normal.
