Is tire noise louder in summer or winter?
2 Answers
Tire noise is louder in winter because the rubber becomes relatively softer in summer. New tires produce more noise: New tires generate more noise due to greater tread pattern resonance, which increases tire noise. Another reason could be the difference in aspect ratio between new and old tires. New tires have a lower aspect ratio, resulting in a larger contact area with the ground, which also leads to increased tire noise. Additionally, new tires may have harder rubber compounds, contributing to louder noise. The influence of tire pressure: Tire pressure is closely related to tire noise, as it significantly affects the noise level. If the tire pressure is too high, the tire becomes more rigid, leading to increased noise. Conversely, if the tire pressure is too low, the contact area between the tire and the ground increases, raising the friction coefficient and resistance, which not only makes the noise louder but also increases fuel consumption.
Usually, tire noise is louder in winter because the cold weather makes the tire rubber harder, causing more intense vibrations on the road and generating more friction noise, which sounds particularly harsh. In summer, the heat makes the tires slightly softer, reducing the noise, but this isn't always the case—dry roads, heavy rain, or severe tire wear can also increase noise. Many car owners complain about the annoying humming noise while driving in winter, which is due to the increased hardness of the tires at lower temperatures. Additionally, tire pressure should be checked regularly, and proper adjustments can help reduce noise. If the tire noise becomes too loud and affects your driving mood, it's best to switch to all-season tires or get a professional maintenance check to ensure safe travel.
