Fix excessive tire noise by correcting tire pressure, wheel alignment and balance and by ensuring the wheels are not bent. Also, check the struts and bearings, and monitor the tires for strange wear patterns that could result from problems other than the noise.Continue Reading
Causes of tire noise include worn-out tires, tread design, faulty wheel bearings, the air chamber and low tire pressure. High-speed cornering, hard braking, rapid acceleration and carrying a heavy load can also cause excessive noise. Tires become noisier as they wear down. Unevenly worn out tires have a non-uniform contact with the road that leads to noise and steering wheel vibration. Avoid uneven wearing by ensuring proper tire rotation and wheel balancing.
Different tire designs and compounds produce different levels of noise. Tire treads intended for heavy loads or off-road grip cause more noise than smooth road treads. Tires with a single pitch pattern throughout the circumference are noisier than those with block patterns of different sizes and shapes. Faulty wheel bearings cause noise in the tire area. A broken wheel bearing can cause uneven tire wear.
Ensure proper tire pressure to avoid road noise. The air chamber in the tire produces a low-frequency hum when the tires roll in motion. The hum can change to a drum-like noise when driving through rough terrain. Widgets such as the Pirelli noise-canceling system aim to eliminate this noise.Learn more about Tires, Rims & Wheels
