The differences between Michelin Primacy LC and Primacy 4 are as follows: I. Different product specifications. 1. Primacy tire specification is 215/55R17. 2. Primacy LC tire specification is 235/55R17. II. Different speed ratings. 1. Primacy speed rating is V (maximum 240 km/h). 2. Primacy LC speed rating is H (maximum 210 km/h). III. Different technical features. 1. Primacy tread pattern adopts variable pitch block design. Four longitudinal grooves divide the tread pattern into five blocks, with the middle three blocks having identical patterns. All pattern blocks use variable pitch design to disrupt noise during tire operation, achieving noise reduction effects. 2. Primacy LC tires adopt the 'Silent Rib' technology, which can effectively reduce tire noise by one decibel compared to the already good noise reduction performance of Energy-MXV8.

I've been driving a city commuter car for many years. The Michelin Primacy LC is mainly characterized by low noise and comfort, driving as smoothly as sailing a boat, making it suitable for daily commuting. However, its grip on wet roads is slightly weaker, making it prone to slipping. The Primacy 4 has upgraded the rubber compound and tread design, significantly reducing wet braking distance with stronger grip and much higher safety ratings, while also improving wear resistance. Although it's a bit more expensive, its overall lifespan is longer, making the cost-performance ratio even better. For families like ours who frequently drive on highways, the Primacy 4 reduces the risk of accidents, making rainy night driving much safer. Regular tire pressure checks can extend its usage, and Michelin is now promoting this new series.

As a car enthusiast, the Primacy LC's noise reduction is absolutely amazing. The rubber is soft, making city driving silent and enjoyable. The Primacy 4 significantly enhances wet road performance, with new grooves and rubber compound reducing braking distance by nearly 20% on wet surfaces, plus improved durability with much slower tread wear, which is crucial for high-speed driving or cornering. The Primacy LC's design is a bit outdated, with higher risk of hydroplaning on wet roads, while the Primacy 4 offers comprehensive balance and is worth the investment. Michelin's generational technology is truly considerate, making adaptation to different road conditions much easier.

The biggest fear when driving is slipping and causing accidents. The Bo Yue LC is comfortable but has average wet grip and weak drainage, making it prone to losing control. The Hao Yue 4 features deep groove design and innovative technology, offering strong wet grip and more reliable braking, reducing accident rates in rainy or snowy conditions. In terms of safety, the Hao Yue 4 wins by a large margin. It performs well whether used on older or newer cars.

Budget-conscious car buyers may find the initial price of Bo Yue LC slightly lower, but the Hao Yue 4 offers better wear resistance and double the lifespan, saving money on tire replacements in the long run. Performance-wise, the Hao Yue 4 provides more stability and safety on wet roads, while the older Bo Yue LC model is quieter and more comfortable but less cost-effective due to frequent tire changes. Opting for the Hao Yue 4 means long-term savings.
