What are the differences between Michelin tires with ST and without ST?

Michelin tires with ST represent Michelin's silent tuning technology for tires. Here are the detailed introductions to the relevant content: Introduction: Michelin tires place great emphasis on tire noise testing. During testing, Michelin tires need to comprehensively consider various data of the car's original sound under multiple conditions, and after repeated calculations, the noise level of Michelin tires is determined. The tread pattern affects tire noise, and the air gaps between the tread patterns of Michelin tires are the main source of tire noise. However, Michelin ST tires have almost no tire noise. Tires with tread patterns that have drainage functions can provide better grip. The role of ST tires: comfortable driving and low tire noise during operation. While maintaining Michelin's high safety performance technology, the tires enhance their noise reduction function by changing the tread pattern and other technologies. The unique tread design of Michelin ST tires can meet the daily driving requirements of car drivers for comfort and tire noise.
I sometimes tow a small trailer with my SUV and have learned a lot about Michelin tires. Tires with ST are specifically designed for towing, such as RVs or boat trailers. They feature thicker sidewalls and higher load capacity to handle the extra weight and pressure from towing. In contrast, regular tires without ST are better suited for daily driving, prioritizing comfort and fuel efficiency, but they can be prone to wobbling or blowouts when used for towing. From personal experience, I once used regular tires for towing and felt unstable on the highway. After switching to ST-rated tires, the stability improved significantly. The key difference lies in the required air pressure: ST tires need higher pressure settings, like 40-65 psi, while regular tires only require 30-50 psi. Safety is crucial here—choosing the wrong tires poses significant risks. Before towing, I recommend checking the tire markings; ST tires are clearly labeled "Special Trailer," which regular tires lack. During maintenance, frequently checking the pressure gauge can extend tire life and reduce issues.
As a car enthusiast, I often study tire details. Michelin tires with the ST designation are specifically optimized for trailers, featuring reinforced structures such as thickened sidewalls to handle higher loads and stability. In contrast, standard tires without the ST marking are designed for passenger vehicles, focusing on smooth driving and fuel efficiency. The performance differences are notable: ST tires reduce sway when towing heavy loads, while standard tires provide smoother acceleration. Avoid mixing them, as using standard tires for towing can lead to rapid wear or even loss of control. The recommended tire pressure also differs—ST tires require over 50 psi, whereas standard tires only need around 30 psi. When selecting ST tires, I recommend checking for the "ST" marking on the sidewall, which is absent on standard tires. Regarding trailer maintenance, regular balancing adjustments can enhance overall safety. Ultimately, from a practical standpoint, matching the tire to its intended use is crucial.
