Falken Azenis RS820 vs Michelin Pilot Sport 4 S

Test Results

Independent comparison tire tests are the best source of data to get tire information from, and the good news is there have been three tests which compare both tires directly!

While it might look like the Michelin Pilot Sport 4 S is better than the Falken Azenis RS820 purely based on the higher number of test wins, tires are very complicated objects which means where one tire is better than the other can be more important in real world use.

Let's look at how the two tires compare across multiple tire test categories.

Key Strengths

Falken Azenis RS820

• Solid dry-road stability and harmonious, progressive handling
• Competitive rolling resistance in one test (−2.2% vs Michelin)
• Curved aquaplaning win in Sport Auto, suggesting good lateral water evacuation
• Generally the most budget-friendly option in test groups

Michelin Pilot Sport 4 S

• Consistently shorter dry and wet braking (up to ~6% in wet)
• Best-in-test dry handling pace and balanced, precise steering
• Stronger wet handling and aquaplaning resistance overall
• Lower noise and broadly superior real-world predictability

Real World Driver Reviews

Tire Reviews also collects real world driver reviews for the Falken Azenis RS820 and Michelin Pilot Sport 4 S.

In total the Falken Azenis RS820 has been reviewed 7 times and drivers have given the tire 90% overall.

The Michelin Pilot Sport 4 S has been reviewed 153 times and drivers have given the tire 85% overall.

This means in real world driving, people prefer the Falken Azenis RS820.

Conclusion

The data is clear: Michelin Pilot Sport 4 S outperforms the Falken Azenis RS820 across most decisive categories, taking both overall comparisons and sweeping dry/wet braking and handling. The margins are modest on dry roads but more meaningful in wet braking (up to ~6% shorter in Sport Auto), reinforcing Michelin's safety and confidence on mixed-weather drives.
Falken shows promise with stable dry cornering feel, a curved aquaplaning win and lower rolling resistance in one test, but it trails in absolute grip and predictability at higher speeds, with more noise and instability on track. If you value top-tier precision, balanced behavior, and wet security, Michelin is the safer bet. Budget-focused buyers who mostly enjoy brisk road driving in the dry may find the Falken's value compelling-but it's not yet a PS4 S substitute for demanding drivers.

Key Differences

• Overall results: Michelin 2/2 test wins; Falken 0
• Braking: Michelin leads dry in both tests and wet in both (up to ~6.4% shorter)
• Handling pace: Michelin faster in dry and wet laps in both tests
• Aquaplaning: Michelin stronger in straight-line; split in curved (Falken wins once, loses once with a big deficit in Autobild)
• Noise: Michelin quieter in both tests (~1-1.4 dB advantage typical)
• Efficiency: Rolling resistance split-Falken better once, Michelin once; Falken positions as better value

Overall Winner: Michelin Pilot Sport 4 S

Based on the tire test data and user reviews we have in our database, the Michelin Pilot Sport 4 S has demonstrated better overall performance in this comparison. However, as you can see from the spider diagram above, each tire has its own strengths which should be considered in your final tire buying choice.

Footnote

This page has been developed using tire industry testing best practices. This means we are only comparing tests which have had both tires in the same test.

Why is this important? Tire testing is heavily affected by things like surface grip levels and surface temperature, which means you can only compare values from the same day. During a tire test external condition changes are calculated into the overall results, but it is not possible to calculate this between tire tests performed on different days or at different locations.

As a result you will see other tests on Tire Reviews which feature both the %s and %s, but as they weren't conducted on the same day, the results are not comparable.

Lots of other websites do this sort of tire comparison, Tire Reviews doesn't.
