What Are the Reasons for Noise from Newly Replaced Tires?
1 Answers
Often, the increased noise from new tires is due to the larger tread pattern resonance of the new tires, which leads to louder tire noise. It could also be because the aspect ratio of the new tires differs from that of the old ones—new tires with a lower aspect ratio have a larger contact area with the road, resulting in more noise. Additionally, the harder compound of new tires can contribute to increased noise. Another possible reason for the humming noise after replacing tires is improper installation methods during the tire replacement process: After replacing the tires, if the technician did not perform dynamic balancing, it can lead to uneven resistance and wear among the tires, causing "tire cupping." Newly replaced tires might be wider than the old ones, increasing the contact area with the road and thus raising friction and noise. The heightened noise level compared to before may make the driver perceive an abnormal humming sound. During the tire replacement process, certain steps might not have been properly executed, potentially causing issues with the wheel bearings. Therefore, to minimize noise issues not caused by the tires themselves, the following measures should be taken: Regularly check tire pressure to ensure it remains within the normal range; Perform dynamic balancing after tire replacement to prevent uneven tire wear; Ensure the specifications, tread patterns, and brands of the replacement tires match the original ones; Note that asymmetric tread patterns and directional tires have specific installation orientations—incorrect installation can increase noise; It is advisable to replace both tires on the same axle at the same time to avoid uneven pressure distribution and increased noise.
