What Causes Loud Tire Noise in BMW?
1 Answers
BMW loud tire noise is caused by severe wear on the tire tread. Below are the reasons for loud tire noise in BMW and the influencing factors of tire noise: Reasons for loud tire noise in BMW: Driving on poor road conditions or having damaged tires, sudden changes in tire pressure. When the vehicle is in motion, tire noise is generated. The formation of tire noise is related to the severity of tread wear, road roughness, road structure, road material, tire pressure, and tire size. Influencing factors of tire noise: Road structure: The friction and vibration occur when the tire tread meets the road surface. Different road surfaces and tires create different levels of friction and intensity, resulting in varying levels of tire noise. Especially when driving on rough roads, the strong friction and impact between the tread and the ground, along with the resonance amplification through vibrations of components like fenders, make the tire noise more noticeable inside the car. Tread wear: Severe tread wear increases tire vibration noise. The condition of tread wear is related to tire pressure, wheel alignment, and driving style. If the tread wears unevenly, check whether the tire pressure is normal, wheel alignment is accurate, and if there is aggressive driving—all of which are factors that accelerate tread wear. Tire pressure: Abnormal tire pressure affects tire noise, which is also a common reason for loud tire noise in new cars. When the tire pressure is too high, the tire becomes harder; when the tire pressure is too low, the contact area between the tire and the ground increases. Both scenarios intensify the friction between the tire and the road, causing tire noise. Tire tread pattern design: Also plays a dominant role in tire noise.
