Grip and Long Tread Life, Together at Last
With the Michelin Pilot Sport 4 S tire, you no longer have to choose between wear and grip. This tire delivers exceptional traction and improved tread life. In fact, the tire's tread life outlasts the Michelin® Pilot® Super Sport by 9 percent, ranking it in the upper echelon of ultra-high performance tires.

Superior Tire Design with Rim Protector
With a premium touch finish that provides a dark velvety effect on the outer sidewall and a deeply set rim protector to guard against light tire and wheel damage, these Michelin high-performance summer tires are stylized and highly functional.

Computer-Modeled Variable Contact Patch 3.0
This tire's design reduces hot spots during aggressive cornering to help maximize tread life and optimize performance when operating at higher speeds.

Dynamic High-Performance Tires
Featuring Michelin Dynamic Response Technology, the Michelin Pilot Sport 4 S tire constantly adapts to road conditions for unrivaled cornering power. A dynamic tread compound offers wet and dry grip as needed.

Poor quality and disappointing

My 2025 Gle53 amg has only 14632 miles on it and this tire has already failed. I am surprised at the dry rot and i have a lot of tread left on this tire and the other three but it is no longer safe to drive anymore.

Really Wanted the New Pilot Sport 5's

These tires were OE on my 2023 AMG SL 63. Great handling, precise response and grip but terrible tread wear. Got only 13,000 miles!!! I wanted to replace them with the new Michelin Sport 5's but they weren't available for the front so I reluctantly went with another set of the Pilot Sport 4 S. I briefly considering going with the Pilot All Season, but I wasn't willing to sacrifice the performance aspect of my car for convenience.

Sports Car Tire

I drive a sports car, and I drive it like a sports car. I don't track, or autocross, or stunt, or drift, or rip sweet smokey burnouts. I just want my tires to stick to the road, and that's what the Pilot Sport 4S does. You can lean hard into turns with confidence. Your wife will squeel long before the tires do. Braking is excellent. She'll be stomping on her imaginary peddle, but you can stop on a dime. Plus, it's good to make sure those seat belt tensioners work. These tires have very low road noise too. They won't drown out the sound of your engine, music, or her telling you to slow down. These are proper sports car tires. I highly recommended them.
