Kumho Ecsta PS91 Tire Review & Rating

New for mid-2016, the Kumho Ecsta PS91 max performance summer tire is the latest addition to the company’s tire lineup. Designed for use on all types of high-performance sports cars and luxury sedans, the Kumho PS91 sports F3 racing tire technology and is considered by Kumho to be their “most advanced tire it has ever produced”.

Kumho uses a new carbon black and silica tread compound that contains Max Grip Performance Resin and matches it up with an asymmetric tread pattern to deliver exceptional dry and wet handling to go with maximum cornering grip. It’s a strength for this tire and we’ve heard the same things from numerous driver reviews as well.

+
The tire’s notched continuous center rib and stiffer tread blocks quicken steering response and give the tire added responsiveness and high speed stability. Kumho’s unique 3D Dimple Design minimizes heat buildup in the tread blocks. The dimples absorb the excessive heat and helps to increase tread life, durability and performance.

With its four wide circumferential grooves and slanted lateral grooves, the Ecsta PS91 effectively channels away water for enhanced traction on wet pavement. Although arguably not among the best in class for wet grip, it performs quite well.

Inside the tire are two high-tensile steel belts with a rayon cord casing and two nylon cap plies. Together it gives the tire added strength and increased durability. Kumho offers a wide range of 18-20 inch sizes. All PS91 sizes come with a Y-speed rating.

Pros

• Dry and wet traction among best in class
• Excellent cornering grip and stability
• Quiet ride for a UHP tire
• Value and performance for the money is outstanding

Cons

• Would like to see 16 and 17 inch sizes available
• Too early to know how well the tread will last (We will update later)

Overall Thoughts

We’ve reviewed hundreds of tires on this site and it often becomes difficult to come across a new tire that really stands out on its own, but that is exactly what you’ll find with this new Kumho PS91.

There’s not much that we can add without it sounding like we work for Kumho, but this is simply one of the better performance tires to hit the market in recent years. It was definitely built to deliver extreme dry and wet traction, handling and performance on the street or at the track.

Point this tire in the direction you want to go and hold on. Cornering grip is on par with that of the Michelin PS2, Continental DW and other top tires in this class. It holds the road like glue and we don’t say that lightly.

If you’re in the market for max performance summer tires that nearly rival the likes of the Michelin Pilot Super Sport and other models, but at a cost that is far less, then the new Kumho PS91 makes an excellent choice. Dollar for dollar, it’s hard to find a better performing summer tire.
