Kumho Ecsta PS91 Overview
The Kumho Ecsta PS91 tire is a summer performance tire that works very well in dry conditions, providing ample handling, resistance to rolling, grip, and road feedback. However, this tire is not suitable for use during the entire year, since it cannot provide a stable grip and handling on wet roads, slippery conditions, or icy roads.
According to the 2017 Auto Bild Sports Test, the Kumho Ecsta PS91 earned a middle of the pack rating in the wet braking category, coming to a full stop in just under 49 meters. In the dry braking category, this earned 4th place, showing how this tire is reliable in both wet and dry categories.
However, this tire earned a less favorable ranking in the wet handling category, coming in just 3rd-to-last place. The tire also earned a low ranking in dry handling, only besting the Rotalla RU01 SPace and the Firestone Firehawk SZ90.
Overall, the tire earned 7th place out of 10 tires, with experts stating the tire provides short braking distances on dry roads but does not perform well in terms of wet stability, wet handling, and wet steering.
Furthermore, in the 2017 Sport test, the Kumho Ecsta PS91 got 2nd to last place in the dry handling category, only beating out the Toyo Proxes Sport tire. Therefore, the tire earned 7th place out of 7 tires, earning a last-place score due to the poor grip in wet conditions and low comfort levels.
Lastly, user reviews on Tire Rack gave this tire a 7.6 for wet performance and 8.7 for dry performance, showing how it stands up in both conditions.
According to the 2019 Tire Review Test, this tire earned 7th place, coming in the middle of the pack and the low-end of the spectrum in all handling categories. This tire earned 6th in the dry handling category and 7th in the dry handling category, only losing out to one other tire in each performance test.
This feature is not favorable for this tire, since the dry performance typically scores high in terms of summer performance tires. However, the lack of performance compared to similar high-performance tires shows how this might not be the most durable and cost-effective option for those who want an all-year-round tire.
User reviews on Tire Rack gave this tire 8.8 for dry traction, 8.6 for steering response, and 7.6 for wet traction, showing how this handling can withstand both wet and dry conditions.
This tire earned just a 5.5 for treadwear rating from users, showing how users may not think this is the most durable option for long-term use. This is not a good feature, as users want to buy a cost-effective option that is going to be durable for multiple seasons.
The average price of the Kumho Ecsta PS91 tire is between $112 and $164, based on the size of the tire and the vehicle model. The average price of a high-performance summer tire is between $150 and $180, making this a smart budget option.
However, potential drivers have to keep in mind that previous users’ reviews on Tire Rack did not recommend this tire; only 6 out of every 10 people would recommend this tire to another driver.
Despite performing better than 82% of other max-performance summer tires, this might not be the best option for both wet and dry use.
Noise and comfort
According to the 2017 Sport Test, the Kumho Ecsta PS91 tire earned last place in dry handling, wet handling, and comfort.
However, this tire earned a high-placing 2nd in the 2019 Tyre Reviews test, besting 99.72% of the competition. In this case, the comfort is subjective and depends on the treadwear of the tire, the personal preferences of the driver, and the cost of the tire.
Lastly, according to user reviews on Tire Rack, users gave this tier a 7.7 for comfort, giving the tire a 7,6 for ride quality and 7.8 fr cabin noise.
Recommendations and conclusions
We would recommend the Kumho Ecsta PS91 tire for those who want a cost-effective summer performance option and can provide ample handling and performance. Although this tire has mixed reviews in terms of wet conditions, this tire earns consistently high user reviews and performance rankings in terms of hydroplaning resistance, traction, responsiveness, and stability.
However, drivers might consider purchasing a more well-rounded option if they want a tire that is suitable for both wet and dry conditions without any question. Other tires that performed better in performance tests include the Goodyear Eagle F1 SuperSport, Michelin Pilot Sport 4 S, Continental Sport Contact 6, Falken Azenis FK510, or Vredestein Ultrac Vorti.
Overall, we think the Kumho Ecsta PS91 is a reliable summer tire for those who want a cost-effective, stable, agile, and high-grip tire. According to user reviews on Tire Rack and multiple performance tests, this tire is a smart choice for dry conditions. However, for those who want a durable year-round tire, this might not be the best choice. Based on consistently high rankings, this tire is a high-performing option for summer use in dry weather.
