What are the differences between Michelin 3st and 4st?

[DiLyla]

The differences between Michelin 3st and 4st are as follows: 1. Different drainage performance: Michelin Primacy 4 adopts Evergrip technology with a brand-new tread pattern design, increasing the drainage space by more than 50% compared to 3st, providing excellent drainage performance. During rainy days, a water film is easily formed between the tire and the road surface, significantly reducing the occurrence of hydroplaning to a certain extent. 2. Different rubber compound: Compared to 3st, Michelin Primacy 4 utilizes a new tread pattern design and a new rubber compound, improving the wet braking performance and rolling resistance for both new and worn tires, thereby enhancing safety.

I've used both Michelin Primacy 3st and 4st. The 3st delivers a quiet and comfortable ride, being a classic model, but its wet grip is somewhat inadequate, especially with longer braking distances in rainy conditions, which might compromise safety. The 4st is an upgraded version featuring EverGrip technology, significantly improving wet performance with more prompt and stable braking, along with optimized rolling resistance for better fuel efficiency. In terms of mileage lifespan, the 4st is more durable, promising longer service life and reduced tire replacement frequency. From an overall driving experience perspective, the 4st offers more comprehensive reliability, especially recommended for urban commuting or regions with rainy seasons. After switching tires myself, I noticed slight improvements in noise control. Although the initial cost is higher, it's worthwhile in the long run.

I carefully compared these two tire series when making my selection. The Primacy 3st is a reliable choice, focusing on quietness and comfort. The 4st is the evolved version, with enhanced wet-road safety as its key improvement. The EverGrip design ensures grip doesn't deteriorate as the tire wears. With reduced rolling resistance, fuel consumption naturally decreases, making it both eco-friendly and cost-effective. From my experience, the 4st provides more stable handling, especially when navigating puddles at high speeds without hydroplaning, plus it comes with longer mileage warranty. If you frequently drive long distances or in rainy areas, going straight for the 4st is the right move—it's also simpler to maintain daily, offering worry-free driving.

The Primacy 4st outperforms the 3st in wet performance and efficiency. The 4st features an enhanced drainage design with EverGrip, reducing braking distance by approximately 10 meters in rainy conditions and improving safety. With optimized rolling resistance, fuel consumption is slightly reduced, making it more environmentally friendly and durable. While the 3st offers comfort and quietness, the 4st, with its new technology, intelligently adapts to various road conditions. Upgrading to the 4st is recommended to enhance overall driving reliability.

With two kids at home, safety is the top priority. I've driven the 3st and found it quite soft and comfortable. However, the 4st has significantly improved wet grip, with technologies like EverGrip ensuring more stable braking in rain or snow, making it safer for the kids' school commutes. Its lower rolling resistance saves fuel, and the extended mileage lifespan also saves money. While the 3st is quieter and suitable for daily use, the 4st offers more comprehensive and practical upgrades, especially in safety. Choosing the 4st for a family car ensures long-term protection.

As someone who prefers handling, I've tested both. The 3st focuses on comfort and quietness but has slightly softer steering. The 4st upgrades wet grip, with its Silica compound enabling faster braking response on wet roads, and the EverGrip technology provides more stability and confidence in corners. With optimized rolling resistance, it offers lower fuel consumption and more responsive daily driving. The 3st is comfortable for smooth driving, but the 4st's performance improvements are significant and worth the investment.
