Why is Michelin 4ST cheaper than 3ST?

[LaMaggie]

Michelin 4ST is cheaper than 3ST due to reduced production costs of the 4ST product. Here are the specific differences between Michelin 3ST and 4ST: 1. Drainage performance: Michelin 4ST features a new tread pattern design through Evergrip technology, increasing drainage space by over 50% compared to 3ST, providing excellent drainage performance. During rainy conditions, a water film easily forms 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 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 achieves a 2.4m longer wet braking distance than 3ST, which improves driving safety to some extent.
