Which is quieter, Michelin 3st or 4st?

Michelin 4st has upgraded its noise reduction module, which noticeably reduces noise compared to the 3st during use, and also improves driving comfort. Here are the differences between the two: 1. Different drainage performance: Michelin Primacy 4 features a new tread design through Evergrip technology, increasing drainage space by over 50% compared to the 3st, significantly reducing hydroplaning with excellent drainage. 2. Different rubber compound: Compared to the 3st, Michelin Primacy 4 adopts a new tread design and a new rubber compound, enhancing wet braking performance and rolling resistance for both new and worn tires. 3. Different safety performance: Due to the new rubber compound, Michelin's 4th generation offers excellent braking performance, with particularly outstanding wet braking. Official data shows that Michelin Primacy 4 outperforms the 3st by a full 2.4m in wet braking distance.

I drive a mid-size sedan myself and have used both Michelin 3ST and 4ST for several months. Honestly, the 4ST is noticeably quieter, especially when cruising on highways. The tire's tread design is optimized for noise control, reducing road roar. In comparison, the 3ST can produce a humming noise on certain rough surfaces. I recommend the 4ST to drivers who prioritize comfort—though it's slightly more expensive, the quieter experience on long trips makes for a more relaxing drive. In city driving at low speeds, the difference between the two isn't significant, but when accelerating above 60 km/h, the 4ST's advantage becomes clear. Overall, if you hate tire noise, the 4ST is a great upgrade choice. Don't forget to check tire pressure regularly to maintain performance.

As a car owner who frequently pays attention to tire performance, I have carefully compared the noise performance between Michelin 3ST and 4ST. The 4ST is undoubtedly quieter, thanks to its Silent Groove technology, which effectively disperses noise frequencies. My experience shows that on mixed road conditions, the 4ST reduces high-frequency noise by approximately 30%, while the 3ST is slightly noisier on wet surfaces. The improvement in driving comfort is significant, reducing travel fatigue. When considering an upgrade, the 4ST also offers better durability, averaging an extra 10,000 kilometers, making it cost-effective. After installation, remember to maintain the correct tire pressure for optimal noise control, and don’t overlook the importance of regular maintenance.

I've driven my friend's car with Michelin 3ST and 4ST tires, and the 4ST feels noticeably quieter overall. At highway speeds, there's significantly less tire noise, making long drives less fatiguing for the ears. The 3ST performs decently on city roads but becomes somewhat noisy on highways. I'd recommend choosing the 4ST for its improved tread design that better absorbs vibrations. For daily driving, quieter tires can genuinely improve your mood - especially in heavy traffic where reduced noise brings more peace of mind. Remember to rotate your tires regularly to maintain even wear, which helps sustain noise control performance longer.

From an economic perspective, I have tested the noise difference between Michelin 3ST and 4ST. The 4ST is generally quieter, especially on bumpy roads, as its noise-reducing materials minimize vibration noise. The 3ST is cheaper but slightly noisier, affecting comfort. In real-world driving, the upgrade to 4ST is worth the extra cost, offering long-term fuel savings and quietness. It's recommended to pair it with a good vehicle system, such as using 4ST on SUVs for better noise control. When investing, watch for promotions—sometimes you can get them at standard prices—and don’t forget to check the tire warranty details.

I often use Michelin 3ST and 4ST for my daily commute, with the 4ST offering more outstanding noise reduction. When the speed exceeds 80 km/h, the noise is significantly reduced, and the road noise sensation is much less noticeable. The 3ST occasionally produces slight noise when turning. The 4ST's design focuses on optimizing quiet performance, making it almost silent on smooth roads. For city drivers, choosing it can provide a more stable driving experience. After changing tires, pay attention to road condition adaptation and avoid sudden acceleration to extend tire life and maintain the quiet state.
