What Causes the Tapping Sound from Car Tires While Driving?
1 Answers
Car tires making abnormal noises while driving can be due to excessive tire pressure, foreign objects in the tires, or inaccurate four-wheel alignment. Excessive tire pressure: When tire pressure is too high, the car body bounces when in contact with the road surface, producing noise. To avoid this, regularly check the tire pressure. Use normal tire pressure under normal temperatures, reduce it slightly in hot weather, and increase it slightly in cold weather. Foreign objects in the tires: Noise occurs when debris like stones gets stuck in the tire treads or when foreign objects adhere to the tire surface and come into contact with the ground. To prevent this, regularly clean the tires, such as removing dirt, asphalt debris, stones, and other foreign objects from the treads. Inaccurate four-wheel alignment: If the car produces a rhythmic humming noise at low speeds, which diminishes at high speeds, it indicates inaccurate four-wheel alignment. Long-distance driving in this condition causes significant tire wear and uneven tread wear, leading to noise. You can check by feeling the tire treads—if the inner or outer treads feel uneven, this is likely the cause of the noise. In such cases, visit a car repair shop for a four-wheel alignment and replace the tires if necessary.
