Overall, drivers describe the Kumho Ecsta PS91 as a strong value-focused max-performance summer tire, with many high-scoring reviews praising sharp, responsive handling from its stiff sidewalls and strong dry grip, plus generally low noise levels. Wet grip is often reported as good for the price, but experiences are mixed and several users note reduced confidence in greasy conditions or once tread depth drops. The most consistent drawback across reviews is short/variable tread life (especially on heavier or high-torque cars), making it feel like false economy for some despite the attractive purchase price.

Excellent piece of tire from Kumho.
The price is very good.
Hard sidewall enhanced cornering stability.
Soft compound make dry weather much fun to play.
Aquaplaning no problem.
Love it, definitely 1 of the best tires around.
Top notch Kumho model.
Very good performance tires. Changed from Pirelli P Zero... As it already harden. Too exp on P Zero.. Kumho PS91 is just 70% of its price. It perform well, noise level was almost unnoticeable. Love it.

I have a 5 liter factory supercharged quad cam intercooled rear wheel drive falcon, with 322 rear wheel kilowatts standard, manual 6 spd. Struggled to get rubber that holds the power on corners.
These tires are very grippy, and handle the power down on corners much better than other tires I have used (Dunlops/Nexens), makes the car feel very planted. When going round roundabouts in second and flooring it, the traction TC cuts in, but the level of grip is such that the TC is not overwhelmed like when using other rubber.
Going WOT and fast changing on limiter 1/2 and 2/3 you get chirps, but the tires grip and then pull, whereas using other rubber there was some serious snaking that went on, with the Khumos it gives you that linear smooth unrelenting pulling,
The front tires have a nice firm sidewall, and give very direct steering inputs- making the car feel smaller.
The tires are not comfortable soft squishy in feel- if that is what you are after move on. These are tight firm performance rubber, that are sticky and make your care feel like it is planted into the road.
These are great rubber in the dry for high power rear wheel drive vehicles, not sure how they will go mileage wise, time will tell.
Oh- they are very quiet too.

Replaced Pirelli P Zero k1 tirew with the Kumhos. I am realy happy that i made the change. The tire is better on dry and wet in lower temperatures that the p zero. The p zero is slightly better in wet on warm days, but the kumho has a little bigger level of grip at dry, and does not need that high temperatures. Allso the tire is realy good when puahed hard, doesent lose the grip level by heating up, the level ia going higher and higher. Perfect for everyday and fast road curve driving. Not tested on the race track, but it should perform ok for a street tire. The stif sidewall is allso a good thing, much stiffer than p zero. I can highly recommend that tire, they car has more overall grip than with p zero. Wear looks also ok for now.
FG MK2 XR6 Turbo Ute.
Great tires, 245/35/19 front, 285/30/19 rear.
Feel super grippy, no traction issues wet or dry which is saying something for a turbo charged 6 cylinder ute.
Couldn't score for wear as they are only new, really quiet, comfortable ride, would definitely buy again.
These have easily outlasted my previous tires and provide very good grip in both good and bad conditions. I left the score for "How progressive the tires are at the limit" at 0 because its a cruiser not a street racer!
Just fitted in ,so left "WEAR" blank. Drover in rain (Aussie Ford FG Turbo 270 Kw )-Tires are perfect at take off and hard cornering on the wet also very quiet and gripy.Swapped from KU19 (Done 22,000 Km) ,I was thinking about KU39 but for $20 more choose SP91 (AUD 250 each corner).BTW Kumho's tires are amazing,and not only for the price.
