Bridgestone Potenza Sport vs Kumho Ecsta Sport PS72
Across the tests, Bridgestone repeatedly delivered class-leading stopping power and pace, especially in the wet, while Kumho countered with lower rolling resistance, excellent refinement, and surprising handling competence. The headline? One tyre majors on speed and security; the other leans into efficiency and comfort-yet occasionally challenges the leaders on track-style metrics.
Test Results
Independent comparison tyre tests are the best source of data to get tyre information from, and the good news is there have been two tests which compare both tyres directly!
| Tyre | Test Wins | Performance |
|---|---|---|
| Bridgestone Potenza Sport | one | |
| Kumho Ecsta Sport PS72 | one |
The Bridgestone Potenza Sport and Kumho Ecsta Sport PS72 have an equal number of test wins. However, tyres are very complicated objects which means where one tyre is better than the other can be more important in real world use.
Let's look at how the two tyres compare across multiple tyre test categories.
Key Strengths
- Outstanding wet braking and wet-grip consistency (e.g., 30.0 m vs 35.9 m in AE, best-in-test)
- Strong dry braking and fastest/near-fastest dry handling laps
- Robust aquaplaning resistance (straight and curved) in AE
- Well-balanced, precise handling with good comfort and low noise for a sport tyre
- Low rolling resistance (≈10-12% better than Bridgestone across tests) for improved efficiency
- High refinement: low noise and good ride comfort
- Competitive handling balance; top subjective wet handling in Die Reifentester
- Strong value proposition with performance that can challenge established brands

Real World Driver Reviews
Bridgestone Potenza Sport Driver Reviews
Across 115 reviews, the Bridgestone Potenza Sport is praised for exceptional dry and wet grip, sharp steering response, strong braking, and confidence-inspiring handling, often rivaling or beating PS4/PS4S and PZ4. Many note it performs best when warmed and can be superb for spirited road use, with some citing good value. The most common drawbacks are rapid tread wear, higher noise and a firm ride, noticeable grip drop when cold, and poor durability on track abuse; a few also report slightly higher fuel consumption. Overall sentiment is strongly positive for performance-focused drivers, with caveats on longevity and comfort.

Kumho Ecsta Sport PS72 Driver Reviews
Most drivers rate the Kumho Ecsta Sport PS72 highly, praising its strong dry and wet grip, predictable/stable handling, and short braking distances, all at excellent value versus premium brands. Several note good high-speed stability and early signs of slow wear, with noise and comfort generally acceptable. A minority reported vibration or out-of-round issues that balancing did not fix, which impacted satisfaction for those users.
Based on 20 reviews with an average rating of 83%
They are not loud, but wouldn't they are necessarily quiet. You can hear them a bit depending on the road surface and speed.
Didn’t drive them too much in the rain, but seem to hold pretty well in wet conditions.
Mounted them in march this year and after 10-15k km I don’t see any major wear, but I would have to abstain on this one until I get them properly... Continue reading this review using the link below
Conclusion
The Kumho Ecsta Sport PS72 offers compelling value with lower running costs and high refinement. It posted the lowest noise and significantly better fuel/energy efficiency (≈10-12% lower rolling resistance in both tests). In Die Reifentester it even edged the overall win on balance, with strong wet handling scores and competitive aquaplaning-proof it can perform at a very high level. However, its wet braking proved inconsistent across tests, which is a meaningful safety consideration.
Bottom line: choose Potenza Sport for fast road driving, all-weather summer confidence, and the shortest stops; pick Ecsta Sport PS72 if you value quiet comfort and lower ownership costs, and are comfortable trading some wet-braking margin for price and efficiency.
Key Differences
- Wet braking security: Bridgestone was dominant in AE (30.0 m vs 35.9 m), while Kumho only matched or narrowly beat it in Die Reifentester (23.07 m vs 23.58 m).
- Dry stopping: Bridgestone consistently shorter (e.g., 34.9 m vs 36.8 m, ~5% advantage).
- Rolling resistance: Kumho offers materially lower RR (≈10-12%), aiding fuel economy and EV range.
- Aquaplaning: Bridgestone led straight and curved aquaplaning in AE; Kumho was only marginally ahead in straight-line in Die Reifentester.
- Refinement: Kumho is quieter (AE noise 10.0 vs 8.8) and rides well; Bridgestone slightly more comfortable subjectively in Die Reifentester.
- Consistency across wet disciplines: Bridgestone delivers stable wet performance; Kumho's wet braking varied significantly test-to-test.

Footnote
This page has been developed using tyre industry testing best practices. This means we are only comparing tests which have had both tyres in the same test.
Why is this important? Tyre 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 tyre test external condition changes are calculated into the overall results, but it is not possible to calculate this between tyre tests performed on different days or at different locations.
As a result you will see other tests on Tyre 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 tyre comparison, Tyre Reviews doesn't.
