What are the differences between Michelin 3st and 4st?
1 Answers
Differences between Michelin 3st and 4st: Different drainage performance: Michelin 4st features a new tread design through Evergrip technology, increasing drainage space by over 50% compared to 3st, providing excellent drainage and significantly reducing hydroplaning. Different rubber compound: Compared to 3st, Michelin 4st adopts a new tread design and new rubber compound, improving wet braking performance and rolling resistance for both new and worn tires. Different safety performance: Due to the new rubber compound, Michelin 4th generation offers superior braking performance, with particularly outstanding wet braking. Official data shows that Michelin Primacy 4 achieves 2.4m better wet braking distance than 3st, enhancing driving safety to some extent. Car tire maintenance: Regularly check tire pressure: Tire pressure directly affects tire lifespan. During daily driving, excessive pressure reduces vehicle stability, especially at high speeds where it may cause floating, posing direct safety risks. Low tire pressure primarily increases fuel consumption by enlarging the contact area between tires and road surface. Both overinflation and underinflation can lead to tire blowouts, which are particularly dangerous at high speeds, potentially causing skidding or rollovers. Therefore, maintaining proper tire pressure is crucial. Slightly higher pressure in winter and lower in summer is recommended. Promptly remove debris from tires: Small stones in tire treads can affect tire lifespan and easily cause blowouts. Timely removal of such debris is essential to avoid safety hazards. Monitor tire wear: Tires naturally wear over time. When wear indicators become visible, replace tires promptly as old tires have significantly reduced traction compared to new ones. Delayed replacement may lead to skidding, especially dangerous during rainy conditions. Perform wheel alignment when necessary: Wheel alignment is required when tires show signs of misalignment. Untimely alignment may cause abnormal tire wear, and vehicle pulling could indicate tire issues in some cases. Repair punctures promptly: Even if a punctured tire doesn't leak air immediately, timely repair is necessary. Delayed repairs may render the tire unusable. Note: Don't remove nails from punctured tires immediately - leaving them in slows air leakage until professional repair is available.
