What is the difference between PS4 and PS4S tires?
2 Answers
Here are the differences between PS4 and PS4S tires: different positioning, different formulations used, different performance, and different tread designs. Below are the specific introductions to PS4 and PS4S tires: 1. PS4 is not a run-flat tire. Compared to run-flat tires, its advantages are that the tires are relatively light, which can help save fuel consumption, and the tire material is soft, providing better comfort, especially noticeable during high-speed driving. 2. PS4S is mainly targeted at high-performance models, suitable for 80% street use and 20% track use. It adopts a dual tread compound technology, with the outer tread using a composite elastic compound to enhance dry performance, and the inner tread adding a functional elastomer compound to improve wet grip and braking performance.
As a regular car owner with over a decade of driving experience, I think the main differences between the PS4 and PS4S lie in performance and daily practicality. I've tried Michelin's PS4, which is much more stable on wet roads, quieter, and more comfortable to drive, making it suitable for city commuting or family cars. The PS4S is a lot more advanced—it doesn't drift when cornering at high speeds on sports cars, has lightning-fast brake response, and significantly improves dry grip. However, it's noisier, less comfortable, and more expensive. For daily use, I recommend the PS4—it's worry-free and durable. If you love racing or drive performance cars, the PS4S offers a more thrilling handling experience, but keep in mind it wears out faster, so check tire pressure regularly. Overall, choosing the right tires ensures safer and more fuel-efficient driving.
