Michelin Pilot Sport 4S Vs. Pilot Sport A/S 3+

The Michelin Pilot Sport 4S and the Pilot Sport A/S 3+ are great options if you want your car to perform well under all conditions. Michelin’s Pilot Sport family offers high performance tires designed for road and track use.

While both tires provide similar features, one is better than the other in terms of its longevity and performance. Both tires have different compounds and make use of different technologies to offer the best handling, traction and stability for drivers across seasons.

But which one trumps the other? Let’s find out.

Michelin Pilot Sport 4S

For sports car drivers, Michelin has always been a brand they can trust. Coming from a long line of high performance tires for high-end vehicles, the Michelin family of Pilot Sport series is well known as the tire of choice for most auto manufacturers.

The latest iteration builds on that reputation too, as the 4S is a better version of the already popular Pilot Super Sport series.

The key difference between the two tires, if compared side by side, is probably the use of enhanced rubber compound, developed to provide more stability and traction in normal and track conditions.

Product Information

The tread design is where the 4S comes into its own. While testing a sports car on the track, the construction of the tire is showcased when the car is thrown into corners at high speeds.

The Dynamic Response Technology introduced with the 4S allows the car to remain stable and provides better road traction.

But the compound needs time to build and retain heat to work efficiently. The asymmetrical tread pattern on the 4S is why drivers can run their cars at high speeds.

Another important aspect of this tread design is that, it works in all conditions and surfaces. If heavy snow is avoided, you’d still be in control of your vehicle at high speeds.

It is amazing how Michelin has managed to provide so much versatility in just one tire.


  • This ultra-high performance tire is the tire of choice for most notable automotive manufacturers in the world, especially known for providing seamless grip in high performance vehicles
  • Superior grip, rivalling slick tires which are not road legal, along with great tread life
  • An all-season tire that provides the best handling characteristics of any tire in this price range
  • Only second to brands like Pirelli P-Zero, which is only meant for ultra-high performance vehicles
  • The tire delivers precision steering, outstanding stability and exceptional grip on dry and wet surfaces


  • The only con is that other manufacturers in this range are providing the same, if not, the exact same features

What We Liked About The Pilot Sport 4S

  • The tire of choice, only second to the Pirelli P-Zero range
  • Unmatched grip and traction for track use
  • Priced better compared to the Pirelli range
  • An all-season tire

What We Didn’t Like About The Pilot Sport 4S

  • Ride quality is not as good
  • Road noise could be improved
  • Tread life could be better for the price
  • Cannot be used on snowy roads
  • Loses grip on wet roads
  • Doesn’t fit most vehicles

Michelin Pilot Sport A/S 3+

Another high performance all-season tire by Michelin, the Pilot Sport A/S 3+ is built for sports cars drivers.

The tire also provides good cornering grip at high speeds through the use of a Helio+ compound, which is infused with higher amounts of silica, to promote longevity.

The tread of the Pilot Sport A/S 3+ was inspired by the Pilot Sport summer tire, to be a better rounded all-season tire.

The introduction of the Contact Patch 3.0 technology used in the tire may result in road noise, but helps improves traction.

Product Information

Michelin uses the Helio+ compound that gives more longevity and better treadwear through its life. The tread life is better compared to the Pilot Sport S4 series.

This tire also uses Michelin’s variable Contact Patch 3.0 technology that reduces heat distortion — to help improve responsiveness of the vehicle.


  • Great handling dynamics for dry and wet tarmac
  • Superior control and stability in wet conditions
  • Better tread life compared to the Pilot Sport S4
  • Cheaper alternative to an ultra-high performance tire
  • Better in terms of value for normal sedans and sports cars
  • Better ride quality compared to the S4


  • The only con is that it is marginally better in terms of ride quality, but not as good in providing vehicle grip at high speeds compared to the Pilot S4

What We Liked About the Pilot Sport A/S 3+

  • Better value for money against the Pilot Sport 4S
  • Much better in terms of ride quality
  • Tread wear is better compared to the Pilot Sport 4S
  • An all-season tire with superior control and traction
  • Performs well in wet conditions as compared to the Pilot 4S
  • Is available in more sizes
  • 6-year or 45,000 mile tread warranty

What We Didn’t Like About the Pilot Sport A/S 3+

  • Ride quality could be better
  • Cannot perform as well as the Pilot 4S on dry tarmac
  • Great for high performance vehicles
  • Priced higher against some of its competitors
  • Poor winter season performance

Our Verdict

Michelin’s high performance tires have come a long way. Both tires have been developed after years of research and testing.

We found out that the Pilot Sport 4S is more focused toward track driving and dry conditions, even though it is an all-season tire. But our tests showed that in wet conditions, you are better off using the A/S 3+, since it is a better all-rounder compared to the 4S.

Our tests also showed that the A/S 3+ lasts longer than its counterpart in terms of tread quality. If you are looking for a Michelin tire with all-season capability, good ride quality and moderate track response, you can go for the A/S 3+.

However, if you have an ultra-high performance vehicle and you go on the track often, then the 4S is the tire to choose since it is specifically designed for tracks.

  1. Hi, this is a great review however I’m a bit confused as I didn’t think the Pilot 4S was an all-season tire. It is listed as a maximum performance summer tire on other web-sites. Can you please clarify. Thanks.

    1. My thoughts exactly. The 4S is considered summer tires and the A/S 3+ is considered all-season tires. Got a set of A/S 3+ myself.
