What are the reasons for increased tire noise?

[SanBennett]

The reasons for increased tire noise are: 1. Tire tread design including the arrangement of tread pitch, direction and depth of tread grooves; 2. Tire vibration noise caused by vibration of the tire body and tread parts; 3. Road noise caused by uneven road surfaces; 4. Tire material being too hard. The solutions for increased tire noise are: 1. Adjust the tire pressure to a moderate level; 2. Install vibration damping, sound insulation, sound absorption and buffering materials on the chassis, fenders, and wheel arches; 3. Replace tires with quiet-type tires; 4. Choose smooth road surfaces while driving to effectively reduce friction between tires and the ground, thereby lowering tire noise.

As an experienced car owner, I believe the most common causes of increased tire noise include uneven tire wear or aging. For example, after driving tens of thousands of kilometers, if the tire treads are worn flat or cracks appear on the surface, the noise when contacting the road will become louder. Tire pressure is also a key factor—overinflation makes tires harder, increasing rolling noise, while underinflation causes excessive tire deformation, leading to greater vibration. The type of tire is also important; performance or budget tires are inherently noisier, and some modified tires prioritize grip at the expense of quietness. Road conditions cannot be ignored either—driving on gravel or uneven roads naturally produces more noise. Additionally, foreign objects stuck in the tire, such as stones or nails, can cause unusual sounds. Faults in the vehicle's suspension system, like failed shock absorbers, can amplify noise transmission. I recommend regularly checking tire condition, maintaining standard pressure, and replacing or servicing tires promptly if issues are found—this prevents safety hazards and improves driving comfort. When I encounter this issue, I first visit a repair shop for diagnosis to avoid minor problems turning into major repairs. Choosing low-noise tire models is also very helpful.

Sudden increase in tire noise can be quite annoying. As a driving enthusiast, I often find that severe wear from prolonged use is the main culprit—once the tread is worn flat, rolling noise skyrockets. Especially if the tire pressure is incorrect, either too high or too low, it roughens the tire contact surface, making the noise louder. Driving on rough roads like potholes or gravel paths makes the noise even more noticeable, with the entire car buzzing due to road resonance. Tire type also plays a big role—performance tires designed for speed are naturally noisier. Check the tire surface for bulges, cracks, or lodged small stones, and address them promptly. I recommend buying a pressure gauge for regular checks or visiting a shop for a balance inspection. Switching to quiet tires can deliver immediate results. Regular maintenance is crucial to avoid noise interfering with music or conversations in the car. After all, young drivers prefer a comfortable ride, and keeping an eye on tire condition can save both hassle and money.

From a technical perspective, increased tire noise typically stems from several factors: uneven tire wear causing tread deformation, which generates additional noise during rolling; improper tire pressure settings altering tire stiffness, leading to excessive vibration; suspension system issues such as loose shock absorbers amplifying tire vibrations transmitted into the cabin; uneven tire installation or embedded foreign objects (e.g., small stones) directly creating noise. Road resonance effects should also be considered, as different pavement surfaces alter sound frequencies. Regular checks of tire dynamic balance and pressure are crucial. I've personally used simple tools for self-inspection, and early intervention can prevent potential issues. Never overlook small details, as they often impact driving experience and safety.
