Comparison: Bridgestone Potenza Sport vs. Michelin Pilot Sport 4 S vs. Kumho Ecsta PS71

Let's compare two popular high-performance summer tyres: the Bridgestone Potenza Sport and the Michelin Pilot Sport 4 S. Both models are praised for their high-quality performance in various tests although they feature some drawbacks as well.


The Bridgestone Potenza Sport, manufactured in Poland and Hungary, is known for its impressive wet handling abilities. This tyre gets a score of 87% on our rating scale. However, the model's rolling resistance has been criticized as being high - a trait that even outlaws it in EU due to the new label targets. Also, the tyre's outer shoulder does not hold up to track work efficiently. Unfortunately, this model has been replaced with a newer series. Make sure to check Bridgestone's official website for more details.


On the other hand, the Michelin Pilot Sport 4 S, manufactured in the USA, has been succeeding in most of the tests, with a score of 93% in our rating scale. It offers a comfortable ride and has distinguished safety features, especially in sub limit steering. But even this model isn't perfect as it lacks the sporty feel while driving on tracks. Just like the Bridgestone model, the Pilot Sport 4 S is also being replaced. Check Michelin's official website for more information.


In most tests, the Michelin Pilot Sport 4 S outperforms the Bridgestone Potenza Sport. For instance, the Michelin tyre took the first place in the Autobild test, while the Bridgestone tyre was in the second position. In the SportAuto test, Michelin's tyre also ranked higher than Bridgestone's, coming third out of eleven, while Bridgestone ranked sixth. Nevertheless, the Bridgestone model excelled in certain areas, such as wet braking, wet handling, dry braking, and dry handling.


In conclusion, both the Bridgestone Potenza Sport and the Michelin Pilot Sport 4 S come with their unique advantages and slight disadvantages. While the Michelin tyre offers comfortable and safe rides, the Bridgestone model offers an excellent steering experience. Your right choice depends entirely on your preference and driving conditions.
