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.

I had these tires on now for just over 6 months after swapping out the ES32 ecos that came with my car and quickly noticed a difference on the way back. Steering weight was slightly heavier, more responsive while turning and more steering feedback. While driving hard I haven't heard any tire squeal and grip is more than enough both in the dry and wet. While cruising around town it's reasonably quiet and comfortable for this class of tire. Wear seems to be good so far and I can still see the tread's flag decals on the rears. I would definitely buy these again especially considering they are much more affordable than premium brands while having similar performance.
Replaced my Continental run flats with these and the difference was night and day. No tramming, harshness over the slightest bump. Very quiet and comfortable and good value for money. I have covered 18000 miles on the rear and still showing 4.2 mm. Would definitely recommended.

Having had the 245 section tire on the back of a BMW for around 10,000 miles i finally needed new tires on the front axle as well. The Rainsport 3's the Kumho PS91 have replaced were regarded as a good tire and i didn't think anything was wrong with them while they were fitted but now i realise that the Kumho are a FAR SUPERIOR tire to the Uniroyals.
The car is transformed in both comfort and grip, road feel has increased and the car now feels much lighter on the front axle with the set of four PS91's installed.
The rear tires appear to be wearing well after 10,000 miles, i'm expecting to get that out of them again so i'll be happy with that.
If you were wondering what tire to go for next, a set of these are superb in all conditions, even on some pretty shoddy British roads. They handle normal motorway miles very well, spirited driving and pulling out of junctions in a 310hp BMW with 620 NM of torque gives you no problems, highly recommend, hopefully Kumho continue to make these when i need another set.

Both dry and wet grip is very good!
Very good road feedback.
Advantage of its stiff sidewalls is sharp and fast steering, and disadvantage is lower comfort. (Still more comfortable than OE runflat tires)
Recommended. I will buy again.
My comments for BMW/Mini owners:
If your car has factory-fitted runflat tires and you are thinking about changing to conventional tires, then I highly recommend Kumho PS91. Because of its stiff sidewalls, Kumho PS91's steering character is close to factory-fitted runflats. Never change your factory-fitted runflat tires with convensional tires with soft sidewalls. Otherwise your BMW/Mini will loose its steering and handling character.
I have these on the rear of my 320bhp 530d with over 600lbs of torque, in the dry the grip is very good and can usually floor it off the line and it will sink in and grip without too much fuss, but in the wet once the wear is below 3.5mm its hard to put much power down off the line or floor it below 40mph.
i do around 40k miles per year mostly motorway but i do like to put my right foot down, on corners the rear is stable and not too twitchy which is good for a big barge and the wear is really good in my opinion if you dont floor it all the time causing the tires to self destruct.
The rears on my last set lasted 22k miles, this time around im at 25k miles with about 3mm left.
at around £140 per wheel fitted its not bad and is worth the money.
I fitted these to the front of my Fiat 500x in June and initially thought they were great, 6 months & 6000 miles later the tires were useless, the tires wander badly, were badly worn and much worse both inner walls were deformed to the point that my MOT tester advised me to get rid of them straight away.
Both tires had been maintained at the manufacturers recommended pressure.
Very impressed at the overall performance of the tire and consider it very good value for money.
Confidence inspiring and good feedback.
Only issue would be the wear & tear, which I feel could be better.
Definitely recommended and would buy again.
Had these on for 20,000 miles, and they are now pretty bald! Must admit these grip the road extremely well, i cant complain at all, and wish they did the bigger size for my car! (BMW 640D). On the plus size, even in icy conditions, the grip is extremely good. On the negative side, they don't look particularly special, and because they grip so well, steering at the front becomes very heavy! If they were more widely available, i'd buy them again
Had these fitted to the rear of my Beemer a few weeks ago following the positive reviews. I paid £280 for two (fitted) which is around 60% of the price of two OEM star-rated Pirelli P7s.
They've take a few hundred miles to scrub in, during which time the wet/damp weather grip was truly terrible (even allowing for their newness) and dry weather grip even now is well below what I was expecting. I can feel the car moving around more, even driving at 6/10ths.
On the positive side, feedback is night-and-day better than the Pirellis, and the drop off in grip is progressive, but at surprisingly low speeds.
Truthfully, they feel absolutely 'mid range' - not as bad as budgets, but nowhere near as good as premium tires. I suppose you get what you pay for, but I don't see these as the under-the-radar performance bargain I was hoping for.
2/3rds of the price of a premium pilot sport comparison and 8-9/10ths of the performance. Provided you're not trying to be Nigel Mansell on the public highways I see no reason to buy any different. A good upgrade from the ku39's.
seat leon cupra 280 swapped original bridgestone potenzas which were noisy and hard to the kumho escta ps91 and at £99 a tire i couldn't be happier, more response and grip through out hard cornering. i cannot believe how well they handle wet roads and deep puddles. would buy again
I purchased this tires after some good reviews on the internet. And well, what can I say? I have always driven my cars on P-Zero, Effiency GripPerformance and Potenza's S001's, and this Kumho tire is better then all before. The dry grip is incredible. When pushing the tires to the limit, it stays unbelieveble predictable. It doesn't have any difficulties with the 310HP on the front wheels. Above 50km/ph there is enough grip to prevent spinning wheels.
The wet grip is really good, but also depence on the surface. The straight line wet grip is really good, better than my Vredestein wintertires on wet. The cornering grip in wet is ok. Not spectaculair, but just ok. But again, when coming to the limits, it is really predictable.
The road feedback is the weakest point of this tire. It's not that you don't feel connectec to the road, but you could have had more feedback and steering feel.
The handling on the other side is just outstanding. When turning the wheel this tires immediately want to turn. Wow! They are so sharp and precise. You can have a lot of fun with them. And, the comfort is really good. This tires are more quiet than the Pirelli's, Good Years and Bridgestone's. I can't say anything about the wear at this point, but when comparing the price of this tires against a Pilot Sport for example, wear is almost not relevant based on their price.
Conclusion: the dry grip and handling is just outstanding. Unbelieveble sharp, but not uncomfortable! A definitely buy again!
