What are the differences between Michelin Primacy 4 and 3ST?

[McZoey]

Here are the main differences between Michelin Primacy 4 and 3ST: 1. Drainage performance: Michelin Primacy 4 features a new tread design through Evergrip technology, increasing the drainage space by over 50% compared to the 3ST. Don't underestimate the drainage function of tires. As the saying goes, "Prepare against danger in times of safety," the drainage performance of car tires is extremely important. On rainy days, a layer of water film equivalent to a lubricant forms between the tire and the road surface, making hydroplaning more likely. Good drainage performance can significantly reduce the occurrence of such situations. 2. Rubber compound: Michelin Primacy 4 adopts a new rubber compound with excellent braking performance, resulting in naturally better wet braking distance. Official data shows that Michelin Primacy 4 outperforms the 3ST by a full 2.4m in wet braking distance. It's worth noting that even 0.1m can potentially prevent a major accident, so to some extent, it also enhances driving safety.
