Comparison: Bridgestone Potenza Sport vs. Pirelli P ZERO PZ4 vs. Michelin Pilot Sport 4 S vs. Kumho Ecsta PS71


When comparing two exceptional tyres like the Bridgestone Potenza Sport and the Pirelli P ZERO PZ4, many factors come into play. As seen in various tests, both tyres have proved to be among the best in the ultra-high performance (UUHP) summer tyre category, but they come with distinctive qualities.


Bridgestone, as a manufacturer, is known to deliver high performing tyres and the Potenza Sport proves no different. It get an impressive 89% rating from us. The tyre stood out in tests for its outstanding wet safety and handling, even attaining the second position in multiple tests. It showed excellent performance in wet braking, safety, and handling, coupled with superb dry handling. However, it is important to note that it had prolonged braking distances at low temperatures and on wet roads. Additionally, it demonstrated weak dry braking and higher rolling resistance. Still, it was generally viewed as a sharp and safe option for both wet and dry tracks.


On the other hand, Pirelli P ZERO PZ4 receives a strong approval rating of 85% from us. Even though it often ended up slightly behind the Bridgestone Potenza Sport in some tests, it still put up a solid performance, especially in dry steering response and handling. Additionally, Pirelli considerably impressed in aquaplaning - longitudinal, exterior noise, wet circle cornering, and dry handling. Unfortunately, the tyre showed weak performance in wet braking and came with increased rolling resistance. In spite of that, it was praised for its great controllability and balance on wet tracks, with fine-tuned balance in curves.


When tallied over multiple tests, the Bridgestone Potenza Sport appears to perform marginally better than the Pirelli P ZERO PZ4, considering the percentage ratings and its repeated second position in tests. However, it's crucial to consider the type of driving you plan to do and the features that are most important to you. Both tyres have unique strengths that may be appealing to various driving conditions.


Neither tyre has been replaced by a newer model. So rest assured with the quality and engineering of both the Bridgestone Potenza Sport and the Pirelli P ZERO PZ4, acknowledged as best in class in high performance summer tyres.


In conclusion, both tyres have their strengths and weaknesses, with Bridgestone standing out in wet and safe handling and Pirelli excelling in steering and balanced performance. Ultimately, the choice between the two will boil down to personal preference and specific driving requirements.
