Why Do Tires Make Noise When Starting the Car?
2 Answers
Here are the reasons why tires make noise when starting the car: 1. Inaccurate four-wheel alignment: A rhythmic humming noise occurs at low speeds and diminishes at high speeds. Incorrect four-wheel alignment causes uneven tire wear over long-distance driving, leading to irregular wear patterns that produce noise. If you feel uneven tread patterns on the inner or outer edges when touching the tires, this is definitely the cause of the noise. Always perform a four-wheel alignment before replacing the tires. 2. Damaged wheel bearing: The noise is less noticeable at low speeds but produces a consistent humming sound at high speeds. This phenomenon occurs when one of the wheel bearings is damaged. Long-distance driving places high demands on wheel bearings, and bearings of poor quality or those that have been used for a long time may fail due to fatigue under prolonged high-speed operation, resulting in noise. Visit a service center to diagnose the noisy component and determine which wheel is affected for replacement.
I just got my driver's license not long ago, and one time when I started my car, the tires kept making noise, which startled me. Later, I asked a friend and realized it was caused by tire slippage. Possible reasons include tire pressure being too low or too high, resulting in insufficient friction; or severe tire wear with shallow treads that can't grip the road properly; slippery road conditions, such as after rain, which make it easier for tires to slip and make noise; or when you press the accelerator too hard, the engine power is too strong, and the tires can't keep up with the speed. I think new drivers must be careful and regularly check whether the tire pressure is within the range recommended in the manual, roughly every two months. Using summer tires in winter will make more noise because the material is harder. Now I've developed a habit of checking the tire condition every time I wash my car to avoid unexpected slippage affecting safety.
