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

[DelAriana]

The differences between Michelin Primacy 4 and 3ST tires are as follows: 1. Different drainage performance: Michelin Primacy 4 features a new tread design through Evergrip technology, providing over 50% more drainage space compared to 3ST, significantly reducing hydroplaning with excellent drainage. 2. Different rubber compound: Compared to 3ST, Michelin Primacy 4 adopts a new tread design and new rubber compound, improving wet braking performance and rolling resistance for both new and worn tires. 3. Different safety performance: Due to the new rubber compound, Michelin Primacy 4 offers superior braking performance, especially in wet conditions. Official data shows that Primacy 4 outperforms 3ST by a full 2.4m in wet braking distance.

I usually enjoy researching car accessories. The Primacy 4 is an upgraded version of Michelin's 3ST. The main difference lies in the tread compound, where the 4th generation uses a new high-silica formula, improving wet grip and braking performance, especially making it safer during the rainy season. The tread pattern has been redesigned with more longitudinal grooves, enhancing drainage while reducing noise and vibration. Additionally, the 4th generation offers improved durability, with a more optimized overall tire structure that can withstand more complex road conditions. From what I understand, the Primacy 4 is more suitable for urban driving that prioritizes comfort and safety, while the 3ST, although also good in terms of quietness, performs slightly weaker in wet conditions. It's recommended to consider local weather conditions when changing tires. If you can use them for a few more years, upgrading to the 4th generation is more cost-effective, after all, driving safety comes first.

As a seasoned driver with over a decade of experience, I've tested both the Primacy 3ST and the 4th generation. The most noticeable differences lie in comfort and noise control: the 4th generation is significantly quieter, with much less cabin vibration during high-speed long-distance driving, giving a new-car feel. In terms of wet grip, the 4th generation offers faster braking response in rainy conditions without tire slippage, boosting driving confidence. The 3ST performs decently on dry roads but tends to slip on wet or mountainous terrain. I also observed that the 4th generation has better shock absorption on bumpy roads, providing a smoother ride with substantial comfort improvements. Overall, the Primacy 4 delivers superior comprehensive performance, making it ideal for daily commutes or long trips. If you're considering tire replacement, prioritizing the 4th generation can save considerable hassle, as driving experience directly impacts both mood and safety.

Michelin launched the Primacy 4 to address some shortcomings of the 3ST, with new improvements including enhanced wet grip and upgraded noise reduction technology. The fourth-generation tread uses silica-based materials, which can quickly drain water in the rain to prevent hydroplaning. At the same time, an optimized sound insulation layer has been added to make driving quieter. These changes make the fourth generation more reliable than the 3ST, especially in rainy areas. I recommend choosing the fourth generation because it balances safety and service life. Although the price is slightly higher, it's worth it.

Considering cost-effectiveness, the price difference between Primacy 4 and 3ST is small, but the 4th generation is more durable. Having changed tires multiple times, I found the tread wear on the 4th generation is slower with longer lifespan, resulting in lower cost per kilometer. The 3ST shows faster noise increase and noticeable grip reduction in mid-to-late stages. The 4th generation performs stably on mixed road conditions, making it suitable for family car owners to control budgets. Additionally, regular tire pressure checks after installation are recommended for safety. Long-term use of the 4th generation can save on maintenance costs – after all, one less replacement means savings.

From a safety perspective, the Primacy 4 outperforms the 3ST significantly in wet conditions and braking performance. I've conducted tests in severe weather, and the 4th generation maintains firm grip on muddy roads without any skidding, while braking distance is several meters shorter. The upgraded tread material is key, enhancing water evacuation and adhesion. In contrast, the 3ST proves somewhat unreliable under similar conditions. Owners are advised to opt for the 4th generation for rainy-day driving assurance, while also maintaining proper care like rotation to extend lifespan. Overall improvements deliver greater driving peace of mind.
