[McCody]

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.
