They are a good affordable tire my main issues with them were they struggled for traction when moving off in the damp/wet and they wore down to the legal limit in less than a year but they gripped very well once up to speed in dry and wet conditions and held the road very well.

The PS71's are joy in the dry and the wet, warm or cold.
First let's give a comparison. I bought my MX5 with Dunlop Sport Maxx RT (these only had 3mm of tread so only had them on for about a month) and they were outstanding in the dry, the wet not so good but I put this down to the age of they tires and the fact that they had only 3mm of tread so lets not put down those amazing Dunlops.
Compared to those, the PS71's have slightly less maximum grip in the high speed stuff and maybe not as fast turn in. Discarding those very subjective points I cannot fault these. In the dry they are outstanding and cannot spin the wheels at all, tight country corners taken fast these are absolutely amazing. medium speed corners id say the Dunlops are better but in High speed the Kuhmo's take over again.
In the wet the PS71's have so much damn grip it is unbelievable. I have so much confidence in the car and the only way I've lost traction in them is doing a standing wheel spin launch on purpose. Other than that they have never done anything I didn't expect them to and for the price of (£80 fitted each) I bought them for, these tires are such such great value considering all the premium brands start at around 110 per tire and that only goes up from there for some decent UHP tires in this kinda odd 205/45/16 size that my MX5 has.
Honestly id buy them again and again. Amazing tires that are very very underrated.

Bought these and fit on Alfa Romeo Goulia 2.2 d rear wheel drive. My car has a 450 Nm of torque on rear axle, and they are surprissingly good, car almost never engages traction control, on all conditions. Dry and wet grip excellent, aswell as handling and road feedback. They feel confidence even at wet conditions and sporty driving. Comfort no problem, but biggest advantage is wear, almost no wear after 10.000 km. Recently have Goodyear AS3, and Continental SC5, which were done after one summer. Excellent tires, and would definitelly recommend and buy again.

These replaced Continental premium tires. Generally they seem pretty good but there are time the car loses grip and bring on the traction control light, in slightly damp conditions it wouldn't with the Continental. That said they are a pretty cheap tire.

Awesome grip from the kumho ps71 i was shocked by the grip in both wet and dry conditions on my S3 8p they give me alot of confidence in all summer UK conditions will definitely be buying again. I have come from ad08r previously on a 400bhp fwd car.

Long story short, I am dissapointed of these tires. Bought them because price is really good and after all it is a Korean brand. I am driving a saloon with only 150 bhp and they still can't cope. Start spinning half throttle even on dry road. Wet is even worse. ESP is working really hard to keep you going. Haven't done hard braking fortunately, but I am worried about it given the lack of grip. Aquaplanning resistence is decent, you can drive 100-120 km/h on a wet highway without any issues. I guess the tire compound is too firm because wear is very little. On the positive side, they are very quiet. Comfort is average, but summer tires are much firmer than winter so maybe it is normal.

Comparing to the OE tires (Pirelli Scorpion Verde runflat), Kumho Ecsta PS71's side wall is notably softer, resulting in less road feedback. Steering is a bit vague around centre, but still precise when more steering is input. Afterall, sportiness is not the priority of this vehicle (2017 Mercedes-Benz GLC300 4MATIC). PS71 is comfortable over bumps, while its noise level is subjectively acceptable. Using them only for front tires for now, I have not driven them to the limit yet. So far no drama, wet or dry. I will keep an eye on them in the coming mileage. Reasonably priced, I am considering to buy another pair to replace the aging OE tires on rear axle.

They aren't the greatest tires I've ever had on a car - but I have these on my Tucson that is used predominantly for road trips in mixed weather and they handle amazingly well in the rain.. - In scenarios where I am convinced I would aquaplane in my other car - these things cut through the water and keep their grip. Took the car around Europe and around the Scottish coasts and just exuded confidence in extreme rain conditions. Not a snow tire.. - but I carry road chains for Alpine driving in snow and these tires take the chains well.. - So not terribly worried about this. In terms of dry use: Nothing special, but decent for the price.. - Have only done 8000 miles and wear seems OK...

Only traveled 200 kilometers so far but at this stage they are a fantastic tire, replace all 4 for Kuhmo ps71, very quite , nice ride definitely improved over worn conti 5 on the front and Bridgestone on the rear, grip is great in the hot weather so far weve had, will update in a few months with some more ks on them

Got the car with kumho tires on it. Done 40k km with them and they were great. Changed them for Goodyear's... In the dry they had almost the same grip as Goodyear but in the wet they are ok for normal driving but not spirited.

Fitted a full set of 4 Kumho PS71 tires and within 9000 miles the fronts were worn down to the minimum depth marker, the two rears whilst still having legal tread depth created a droning noise similar to that of worn wheel bearings, infact I had the car checked in case it was the rear hub bearings that were creating the noise but advised it was the rear tires....changed the whole set to another brand and the noise stopped. Wouldnt by these Ecsta PS71 ever again, I've run other Kumho tire models mostly without issue but they just didnt get the PS71 right as far as i'm concerned.

Fantastic levels of grip in both wet and dry conditions. With the A6 3.0 Quattro you really have to be doing something silly to exceed the limits of grip on the road that these tires offer. They've been fitted to the car for 26,000 miles and have just dropped below 2mm tread on the rear tires in the centre. They were not good in the snow as can be expected from a summer tire.
