Which is quieter, Michelin 3st or 4st?

Michelin 4st is quieter compared to 3st. Here are the specific differences between Michelin 3st and 4st: 1. Drainage performance: Michelin 4st features a new tread design through Evergrip technology, increasing drainage space by over 50% compared to 3st, providing excellent drainage performance. During rainy days, a water film is more likely to form between the tire and the road surface, significantly reducing hydroplaning to a certain extent. 2. Rubber compound: Compared to 3st, Michelin 4st adopts a new tread design and a new rubber compound, improving wet braking performance and rolling resistance for both new and worn tires, thereby enhancing safety. 3. Safety performance: Official data shows that Michelin 4st has a wet braking distance that is 2.4m shorter than 3st, which to some extent improves driving safety.

As someone who frequently drives long distances, I fully understand the impact of tire noise. The Michelin Primacy 4 ST truly outperforms the 3ST in terms of quietness, primarily due to its newly designed tread blocks and rubber compound, which better disperse road vibrations and reduce humming sounds. After testing it on the highway, the cabin noise with the 4ST was noticeably lower, especially on uneven road sections. The 3ST is also part of the quiet series but is older and doesn’t match the noise control of the upgraded model. I recommend frequent highway drivers prioritize the 4ST, as it combines comfort and longevity. Maintenance is straightforward—keeping the proper tire pressure enhances its quiet performance.

After changing tires several times, I found that the Michelin 4ST is generally quieter than the 3ST. In actual driving on ordinary city roads, the difference between the two is not significant, but once on highways or rough roads, the noise suppression of the 4ST takes the lead. The new model has added many detailed optimizations, such as smaller tread gaps, which can buffer vibration noise. However, the 3ST is also not bad and is more affordable. Choosing which one depends on road conditions; if you drive more on highways, the 4ST can enhance the experience. Tire noise reduction is also affected by vehicle weight and speed, so testing it yourself is more accurate.

Michelin's Primacy series has always focused on comfort, and the 4ST shows improvement in noise reduction compared to the 3ST. Test data indicates that the 4ST has slightly lower decibel levels, primarily due to enhancements in sidewall materials. For daily driving, the 3ST is sufficient, but the 4ST performs better. In terms of pricing, the 4ST is slightly more expensive, so if your budget allows, it's the better choice. Don't overlook tire wear, as the noise difference between new and worn tires can be significant.

Many online reviews and user feedback consistently indicate that the Michelin 4ST is quieter than the 3ST. Having driven both models for comparison, the 4ST demonstrates superior noise control on city roads and is noticeably quieter at highway speeds. The new model incorporates updated acoustic technology to reduce tread resonance. However, the 3ST offers better value for money, especially during inventory clearance sales. Driving habits significantly impact the experience—rapid acceleration or hard braking can affect the perceived performance. Opting for the 4ST is recommended for the best overall experience.

As a noise-conscious car owner, I recommend the Michelin 4ST, which is specifically designed with optimized noise reduction. During actual long-distance driving, the 3ST sometimes produces slight humming sounds, while the 4ST offers smoother performance and better handling of tire rolling resistance. Both are excellent tires, but the 4ST is the newer version, making it ideal for those pursuing ultimate quietness. Checking tire pressure and wheel balance can maximize its effectiveness.
