Why Is There More Tire Noise After Changing Tires?
3 Answers
Increased tire noise after changing tires can be due to foreign objects stuck in the tire treads, which can be checked and removed. It could also be caused by excessively high tire pressure or uneven tire pressure among the tires. Additionally, not having a four-wheel alignment done for an extended period after installing new tires can contribute to the issue. Reasons for increased tire noise after changing tires: Increased tire noise after changing tires may be because foreign objects are stuck in the tire treads, which should be checked and removed. Excessively high tire pressure or uneven tire pressure among the tires requires confirmation at a repair shop. Furthermore, not having a four-wheel alignment done after installing new tires or for an extended period can lead to uneven wear among the tires. Precautions for DIY tire replacement: When replacing tires yourself, ensure the lug nuts are tightened to the torque specified in the vehicle manual. However, DIY tire replacement should only be considered an emergency measure. It is recommended to visit a repair shop as soon as possible for a four-wheel alignment to ensure even force distribution among all tires.
I recently changed my tires and noticed a significant increase in noise, so I did some research on this issue. It mainly comes down to the tread pattern design and rubber compound of the tires. Original equipment manufacturer (OEM) tires are all matched with the vehicle's NVH (Noise, Vibration, and Harshness) characteristics. If you choose the wrong tire model when replacing them, especially performance tires or all-terrain (AT) tires with blocky tread patterns, the sound of the tire tread striking the road surface can be amplified. Additionally, installation details are crucial. Last time, my relative's car had unbalanced tires after replacement, causing the entire steering wheel to vibrate and hum. The low-frequency noise generated by tire wobble was even more annoying than regular tire noise. Nowadays, some new tires have a layer of release agent on the surface, and it takes a few hundred kilometers of break-in period for them to quiet down.
I deeply understand the reasons for increased tire noise after tire replacement, which mainly revolve around three key indicators: tire tread pitch, rubber hardness, and installation precision. Hard tires, while durable, tend to be noisier. Improper installation, such as uncleaned wheel hubs or unevenly tightened bolts, can also contribute. Last time I changed tires and drove on the highway, the humming sound from the rear was a classic example of tire noise, later traced to uneven wear caused by misaligned wheel alignment data. When choosing comfortable and quiet tires, pay attention to the width of the drainage grooves; fine, diagonal tread patterns are generally quieter. If the noise is concentrated in a specific area, it might be due to unremoved anti-rust coating on the brake discs, where friction sounds are often mistaken for tire noise.
