Comparison: Bridgestone Potenza Sport vs. Kumho Ecsta PS71 vs. Pirelli P ZERO PZ4

The comparison between the two summer tyres, the Bridgestone Potenza Sport and the Kumho Ecsta PS71, reveals significant differences with performance and rating. Produced by renowned manufacturers Bridgestone and Kumho, these tyres have been featured on a number of tests.

According to our ratings, the Bridgestone Potenza Sport outperforms the Kumho Ecsta PS71 with an 89% rating against a 68% rating. Please note, neither tyre has been replaced with a newer model.

When put to the test by Autobild, the Bridgestone Potenza Sport ranks first out of 52 tyres, excelling in wet circle cornering, wet braking, and dry braking. In stark contrast, the Kumho Ecsta PS71 clinches the fourth position, with its strengths lying in aquaplaning, comfort, wet braking, and wet handling.

ADAC's tests corroborate this, positioning the Bridgestone Potenza Sport on the second spot, while the Kumho Ecsta PS71 languishes at the thirteenth out of 18 tyres. According to autobild 2025, the Potenza Sport boasts excellent properties on dry pavement, good properties in the wet and projects high mileage. The Kumho Ecsta PS71, on the other hand, scores with very short braking distances on dry pavement and good characteristics in the wet, but has been criticized for weak driving comfort on dry roads and reduced safety.

ACE also testifies to the Bridgestone Potenza Sport's prowess, pinning it at the fourth position for impressive wet and dry handling, despite some weaknesses like low aquaplaning resistance, high noise levels, the lowest comfort on test, and the highest rolling resistance. The Kumho Ecsta PS71, occupying the seventh position, shows strengths in aquaplaning.

In conclusion, while both tyres are fundamentally decent options for summer use, the Bridgestone Potenza Sport carries the day in terms of overall performance. This does not disqualify the Kumho Ecsta PS71, but highlights areas that may need improvement. The Kumho has been praised for its low rolling resistance and high aquaplaning resistance, even though its grip in the dry and wet conditions is wanting.

For an all-round, best-rated performance, the Bridgestone Potenza Sport remains an unparalleled choice. However, if comfort and aquaplaning resistance are your number one priorities, the Kumho Ecsta PS71 might be worth considering. Both tyres are testament to the quality one can expect from Bridgestone and Kumho.
