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.

I just got a new set of Primacy 4 tires, confirming it's the Michelin Primacy 4, not that weird 4ST naming. After installation, I drove to work and noticed significantly reduced road noise with much improved comfort. It provides stable grip when cornering in wet conditions without slipping. The Primacy 4 is Michelin's standard model, officially promoted for its fuel efficiency advantages. Though pricier, it's durable - three months of driving with zero issues. For tire selection, keep it simple: just look for the Primacy 4 label to avoid mistakes.

As a parent who drives to pick up and drop off kids, I prioritize tire safety. The Primacy 4 is Michelin's Primacy 4—there's no such thing as a 4ST. Within the Primacy series, the Primacy 4 excels in noise reduction, featuring sound-absorbing materials that reduce cabin noise, making family conversations clearer. It also delivers reliable performance on wet roads, giving me confidence even during rainy highway drives. Its longer maintenance cycle means less hassle, avoiding frequent tire changes. When purchasing, always verify the model is Primacy 4 to ensure correct installation and avoid misleading choices that could compromise safety.

What Causes Car Body Vibration When the Air Conditioning is On?

Car body vibration when the air conditioning is on is caused by carbon deposits on the spark plugs and engine intake valves. The functions of car air conditioning include: 1. Achieving a cooling effect through the continuous transformation and circulation of refrigerant; 2. Using the engine coolant, waste heat, or heat generated by a burner as a heat source for heating. The heater then warms the air, which is blown into the car by a blower, raising the temperature at the air outlets for heating purposes; 3. Drawing in fresh external air for ventilation and air exchange, which also helps prevent windshield fogging; 4. Removing dust, odors, smoke, and toxic gases from the car's interior to freshen the air, as well as humidifying the air to increase its relative humidity.
