What Causes Increased Tire Noise?

Tire noise increase is related to four factors: 1. Tire material: Undoubtedly, tires with softer materials generally have better noise control during driving, but they may lack in wear resistance. 2. Tread pattern design: As tires rotate rapidly during movement, air quickly impacts the tread patterns, and the noise generated from this impact constitutes the main source of tire noise. It can be observed that tires focusing on quiet performance typically feature densely arranged, fine tread patterns. 3. Groove cavity compression: Since tires are made of elastic rubber, when they contact the ground, the compression deformation compresses and expels air from the groove cavities in contact with the ground, generating noise as the air is forcibly expelled. 4. Poor vehicle sound insulation: Inadequate use of noise-reducing foam in the wheel arches is also one of the factors contributing to loud tire noise.

I noticed increased tire noise while driving, which is quite annoying. I need to check the possible causes. The most common issue is tire-related, such as aging or severe wear. When the tread becomes shallow, it tends to produce a humming sound on the road. Additionally, incorrect tire pressure—either too high or too low—can also cause this, so maintaining proper inflation is essential for stability. Another possibility is unbalanced wheels or loose suspension, which can amplify noise over bumps. Road conditions play a role too; newly paved roads are quieter, while older, uneven surfaces tend to be noisier. If the noise becomes more noticeable at higher speeds, it might be due to the tire type—for example, performance tires are initially quieter but become louder as they wear. I recommend regularly inspecting tire condition and replacing them if the edges are worn, as this affects driving safety. Periodic visits to the repair shop for adjustments can prevent prolonged noise exposure, which not only strains your ears but also increases fuel consumption. Overall, maintaining good habits can minimize such annoyances.

Recently, the tire noise has become noticeably louder when driving on the highway, so I really need to pay attention. I think it's mainly related to tire wear. After several years of use, the tires have worn flat, causing uneven contact with the ground, which leads to noise. Tire pressure is also crucial—both overinflation and underinflation are problematic. It's important to inflate them according to the manual, such as slightly reducing pressure during hot summers. If suspension components are worn, like a damaged shock absorber, increased tire vibration can amplify the noise. Additionally, unbalanced wheels or improper tire installation, such as mounting the tread pattern in the wrong direction, can also contribute. Frequent driving on gravel roads can add to the issue due to the rough surface. Ignoring these problems might lead to more serious issues like a tire blowout, so if something feels off, it's best to stop and check or visit a professional shop. Regular maintenance, including checking tire pressure and wear, can prevent a lot of trouble.

When the tire noise increases, I think the reasons are quite straightforward. The main cause is tire wear; shallow tread patterns make more noise on highways. Incorrect tire pressure can also lead to noise when driving on hard surfaces. Additionally, a damaged suspension can increase vibrations. These are the basic issues, and it's best to address them promptly.
