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 tyres 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 tyres were useless, the tyres 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 tyres had been maintained at the manufacturers recommended pressure.

Very dissapointed

Very impressed at the overall performance of the tyre 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 tyres. 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 tyre 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 tyres 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 tyre is better then all before. The dry grip is incredible. When pushing the tyres 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 wintertyres 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 tyre. 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 tyres 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 tyres 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 tyres 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!

Excellent piece of tyre 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 tyres around.
Top notch Kumho model.

Very good performance tyres. 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 litre 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 tyres are very grippy, and handle the power down on corners much better than other tyres 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 tyres 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 tyres have a nice firm sidewall, and give very direct steering inputs- making the car feel smaller.

The tyres 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 tyrew with the Kumhos. I am realy happy that i made the change. The tyre 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 tyre 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 tyre. The stif sidewall is allso a good thing, much stiffer than p zero. I can highly recommend that tyre, they car has more overall grip than with p zero. Wear looks also ok for now.
