The Kumho Ecsta PS91 sounds like the real deal. Is this the right summer tire for your sports car, supercar, or Nurburgring-tuned German sedan? In this Kumho Ecsta PS91 review, I was interested to find out if a tire tuned for maximum grip is not just a one-trick pony with alarmingly low levels of comfort and refinement.
Ultra-high performance summer tires are usually engineered to compromise tread wear and comfort in exchange for maximum traction and grip. Call me old school if you like, but I want my supercar or sports sedan to behave nicely on normal roads, and the tires used will definitely spell the difference between highway comfort and a sore back.
It is only fitting to test the Kumho Ecsta PS91 tires on a proper sports car. Sadly, I had no access to a Porsche 911 Turbo or Audi R8 V10, so I had to make do with the original supercar slayer – the Mitsubishi Lancer Evolution X. In this case, it was a 2014 MR sedan equipped with a six-speed dual-clutch automatic transmission.
The owner of the Evo is in his late 30’s. He fitted the Kumho Ecsta PS91 tires about five months ago. The car used to be his daily driver but is now strictly a weekends-only machine, particularly on track day runs with his buddies who drive equally exceptional Japanese sports cars like the Honda S2000 and Subaru Impreza WRX STi. This is the reason that the tires were already showing signs of wear.
Kumho Ecsta PS91 review: Features
The sidewall of the Kumho Ecsta PS91 has a checkered flag design that clearly portrays the ultra-high performance intent of the tire. Admittedly, the Ecsta PS91 is not the best-looking tire in the business. In fact, it looks a bit ordinary. But thanks to the checkered flag indentations on the sidewall, the tire manages to acquit itself well in terms of looks.
