What are the main reasons for the excessive tire noise in the new Sagitar?

The main reason for the excessive tire noise in the new Sagitar is the friction between the tires and the road surface during vehicle movement, which generates noise. Additionally, the protective covers near the tires and the friction with air also produce noise, which can penetrate into the cabin through the car windows. The solution is to replace the tires with a full set of quiet tires or to add a layer of felt fabric to the protective panels. The felt fabric can effectively reduce the friction noise caused by the uneven surfaces of the panels and air, as well as absorb some of the noise generated by the friction between the tires and the road surface. Taking the Sagitar 2021 200TSI Manual Fashion Smart Connect Edition as an example: it is a compact 4-door 5-seater sedan equipped with a 5-speed manual transmission, with a top speed of 200 kilometers per hour.
I just bought a new Sagitar and noticed the tire noise is particularly loud, especially on highways. After some research, I found this is mainly due to the factory-installed tires. To cut costs, Volkswagen often uses budget-friendly tires like certain Dunlop or Hankook models, which prioritize durability and fuel efficiency over noise reduction. The harder rubber compound tends to generate significant noise when interacting with road surfaces. Another factor is the vehicle's inherent lack of sound insulation - as an entry-level model, the Sagitar may not have premium noise-dampening materials, allowing tire noise to penetrate the cabin directly. Additionally, incorrect tire pressure (either too high or too low) can amplify this sound. After adjusting my tire pressure, I noticed slight improvement. A stiff suspension setup can also exacerbate vibrations and noise. I recommend regularly maintaining tire pressure around 2.5 bar, or directly switching to quiet tires like Michelin or Continental for noticeable noise reduction.
