Is Michelin Primacy 4 the same as 4st?
3 Answers
Michelin Primacy 4 is not 4st. The differences between Michelin Primacy 4 and 4st 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, which significantly reduces hydroplaning with its excellent drainage capability. 2. Different rubber compound: Compared to 3st, Michelin Primacy 4 adopts a new tread design and a new rubber compound, improving both wet braking performance and rolling resistance for new and worn tires. 3. Different safety performance: Due to the new rubber compound, Michelin Primacy 4 demonstrates outstanding braking performance, particularly excelling in wet braking. Official data shows that Michelin Primacy 4 outperforms 3st by a full 2.4m in wet braking distance. Considering that even 0.1m can potentially prevent a major accident, this significantly enhances driving safety to some extent.
I've driven several cars and switched to Michelin Primacy 4 tires, which is what we commonly refer to as Michelin Primacy 4. In the automotive world, Primacy 4 is a tire known for its quietness and comfort, not some 4ST; this name might be an online miscommunication or typo. The Primacy series includes Primacy 3 and Primacy 4, with the latter featuring Acoustic technology, such as built-in foam to absorb road noise, making it extremely quiet at high speeds and providing stable grip in rainy conditions. I've personally tested it on highways and in urban areas, and the fuel efficiency is noticeably better, with tire noise reduced by at least 30%. When buying, just look for the Primacy 4 label on the packaging or the tire sidewall; don't be fooled by other strange abbreviations and waste your money. This tire is perfect for everyday drivers, and those who prioritize comfort and safety should definitely give it a try.
I've worked in a tire shop for several years, and customers often ask if the Primacy 4 is the 4ST. Actually, the Primacy 4 is the official Michelin Primacy 4 tire, and there is no separate model called 4ST. The Primacy ST was the older version, which has long been discontinued. The Primacy 4 is designed with noise-reducing elements, such as optimized tread patterns to reduce vibration, and it excels in noise control. When we receive shipments, the batch numbers always show Primacy 4. Consumers should remember to check the model label before purchasing and not just rely on misleading abbreviations found online. After installation, feedback consistently highlights its strong wet performance and short braking distance, making it ideal for family cars. If you have any questions, come directly to the shop or check the official website for accurate information—don't just guess on your own.
