What Causes the Noise Outside the Window While Driving?

[Smith]

Noise outside the window while driving is usually caused by foreign objects like stones stuck in the tire tread. Here is some relevant information about tires: Tires are rubber products, and rubber deteriorates over time with use, so tires need to be replaced periodically. Under normal circumstances, tires installed on a car can last for four years, so it is recommended to replace them every four years. When purchasing new tires, always check the production date because tires also have a shelf life. Normally, unused tires have a shelf life of three years; if they have been sitting for more than three years, they should not be purchased.
