What is the difference between Michelin PS4 and PS4S?
3 Answers
Precision positioning differences, different formulations used, varying performance characteristics, and distinct tread designs are the key differences between Michelin PS4 and PS4S tires, as detailed below: Precision positioning differences: The Michelin PS4 is precisely positioned as an entry-level high-performance street tire 100% oriented towards urban communities; The Michelin PS4S primarily targets premium performance vehicle models, suitable for 80% street use and 20% track use. Different formulations used: The PS4 utilizes functional elastomer materials, silica compound and proprietary formulation, offering excellent wet surface grip; The PS4S employs twin compound formulation technology, with the outer tread area using a composite elastic formulation that enhances dry performance. Performance differences: The PS4 demonstrates excellent cornering performance and high-speed stability; The PS4S ensures more uniform tire contact pressure and temperature distribution. Tread design differences: The PS4 features a matte finish design on the tire sidewall markings; The PS4S adopts an ultra-dynamic tread pattern design.
I used Michelin PS4 tires for my daily driving before, and found them very comfortable on city roads. They offer strong wet grip, stable braking, and are relatively quiet, with good long-distance wear resistance—a single set can last for years. Later, I tried the PS4S and immediately noticed a big difference: during high-speed dry cornering, they feel more planted, with sharper handling and quicker response, making the car feel glued to the road and boosting confidence at high speeds. However, the trade-off is a noticeably stiffer ride over bumps, reduced comfort and noise insulation compared to the PS4, and slightly higher fuel consumption over time. Overall, the PS4 is better suited for regular commuting or wet conditions, while the PS4S is more ideal for sports cars or enthusiasts who enjoy spirited driving. If you don’t drive fast, there’s no need to spend extra on the upgrade.
I love pushing the limits of handling when driving, often tackling mountain roads and track days. After switching to PS4 tires, the dry grip was decent, but they tended to slide out at high-speed corners, requiring extra caution. Upgrading to PS4S made a huge difference—the handling improved dramatically, offering much higher cornering limits on dry surfaces with no performance drop during continuous high-speed driving. Braking distance also shortened by nearly two meters, significantly boosting safety. The PS4S uses more advanced materials that resist high-temperature wear, delivering stable track performance. However, the downside is a rougher ride during daily commutes, sacrificing comfort, and the price-performance ratio isn’t great. In short, the PS4 is better for everyday driving, while the PS4S is a dedicated choice for performance enthusiasts.
