Tyre Test Highlights

2010 EVO Tyre Test - 7th of 9 tyres

2014 Auto Bild Top 15 Summer Tyre Test - 8th of 15 tyres

  • Positive - Good aquaplaning results, short braking distances on dry roads, quiet pass-by noise, good value for money
  • Negative - Poor mileage, slow steering response

2012 EVO Summer Tyre Test - 9th of 10 tyres

  • Overall - Much closer to the tyres above rather than the Nexen below, the Kumho had a relatively strong wet performance. Slow in the dry, and a dull light steering feel give the Kumho a poor subjective score overall

Top Kumho Ecsta KU39 Review

Given 70% (breakdown) while driving a Ford S Max (225/50 R17 W) on a combination of roads for 10,000 average miles
Good, quiet, responsive tyre with good braking in wet and dry. However, very poor wear longevity. Only had tryes for less than 18 months, do less than 10.000 miles per year and both front and rear are nearly bald. Would not buy again for this reason.

Alfa Romeo (225/45 R17) on mostly motorways for 37,500 average miles

I am better at speaking in English than writing it. sorry for my bad enlgish but i hope you understand!

Dry grip; 8. Well.... when it is summer the tyres are great! Only when it is below under 7 degrees the tyres want to do a step aside. But... If you drive sportive you never have a unsafe feeling in summer.

Wetgrip; 7. If you drive in the rain with a normal road you have 0% stress about the grip, even in roundabouts or in turns on a 60mile motorway the tyre go's wherever you want to go there is no complains about. However. If there is aquaplanning (i dont know if this word is correct cause i'm dutch and here in the Netherlands you have aquaplanning alot), the Kumho's KU39 struggle's with the water... only option is to slow down the speed or doing two hands on your steering wheel! But if you know this and you seeing alot of water on the road you can lowing your speed for like 10km/h's and there are no problems.

Road Feedback; 9. The Kumho's give you always the feeling what's happening. And that's the reason why i love them.

Handling; 10. When you go with to much speed around the corner most tyres you go in to a slip . These tyres don't!!! In all the 37.5000 miles and my sportive drivenstile i have no unsafe feeling when i realy push hard. When you think; Oh shit mayby i'm late to take the corner. No problem... when you want to take a corner on your right... you go that way you want!

Wear; 10. AWESOME. I have an Alfa Romeo 147 JTD 140hp 340nm and i'm drive normal for like 90% of the time. Only i have my moments like everyone.... and then i realy pushed hard around the corners. Sometimes i leave with wheelspin by the trafficlights, or have slippy tyres when i go hard in a sharp turn.

I driven 37.500 miles (60.000km) on 1 set Kumho's KU39 front tyres!!! That's alot. Only they are now gone, and when they are born like now, you have not much grip but it is cold outside and i think that is normal when the tyres have 1.6mm left.

Comfort; 10; No complains about the comfort the sidewall is not soft but bad roads are no problem for the tyres (or your back)

Buy Again; 6. Well it is very hard to find tyres who are 100% what you want IMO. But i tink if you looking for a cheap tyre that makes you happy in all conditions buy the Kumho for sure. If you live in a country where it rains all day mayby you have to look at another tyre like the Uniroyal rainsport 3 (only with aquaplanning you have to pay attention on the road), but if you live in Italy, Kroatiƫ or another warm country the Kumho's ku39 are perfect for you!!!

I give this time the change to Michelin Pilot Sport 4. They are much expensiver then Kumho's..... but YOLO. You can spend out your money 1 time in you life!

Ford (225/45 R17) on mostly country roads for 5,000 average miles
Have not had these long, but weather in Ireland is wet and dry so in a short time it has had good experience on all sorts of roads and conditions. They perform as well as Goodyear Efficient Grip in all areas except one! Rolling resistance must very very high! Averaging 45MPG before i am lucky to break 40MPG now and i only fitted them on the front. Makes a big different over a lot of miles, and wont recover the reduced cost of the tyres. Sorry Kumho, not again!

Given 96% (breakdown) while driving a Mazda 6 Estate 2.2D Soport (225/45 R17) on a combination of roads for 27,000 easy going miles
I have been running these tyres for a couple of years now. Exceedingly good braking response in the wet, by trying REALLY hard I can just get the ABS to kick in on a soaking wet road. Not the quietist of tyres but certainly not the noisiest either. Longevity has exceeded my expectations. 27000 miles out of pair fitted to the front (drive) axle of a 185 BHP Mazda 6. Just bought another two because they offer excellent value for money and I KNOW I can stop in the wet!! Amazing that tyres costing nearly three times as much have a much worse wet braking rating. If it all goes wrong I want to know I can stop!!

Given 91% (breakdown) while driving a Alfa Romeo 147 JTD (215/45 R17 W) on a combination of roads for 20 spirited miles

I'm writing this via google translate as my english is not that good.

I ordered these tires as a friend recommended them. He even drove on the track and these tires, the Kumho Escta Le Sport (KU39) were great tires for street use and possibly a roundabout circuit.

The tires have almost no limit on dry asphalt if they are well-driven. Can bend very hard without losing my grip. Rather; Never lost grip. The tires are somewhat uncomfortable, but I knew that because the XL version was ordered. Also at high speeds, 200km / h the tire gives a lot of feedback and keeps handling, for example, to send left / right to pass a car without the tires getting sluggish, giving you a safe feeling.

Be very satisfied with these Kumho's on dry roads.

On wet roads, the Kumho's also have sufficient grip on bends. Only what I find so strange is that the tires have enough grip on a normal wet road. And lose their grip on aquaplaning and give you an unsafe feeling.

That's the only thing to complain about.

Have the tires now 20.000miles. And there is still a profile. So the wear is very good.
