Tyre Test Highlights

2014 Auto Review Max Performance Tyre Test - 7th of 7 tyres

  • Positive - Price
  • Negative - Grip and control on wet pavement, low resistance to aquaplaning, grip and handling on dry pavement
  • Overall - The Kumho KU31 looks smart, but unfortunately doesn't deliver in test. On wet roads the performance is mediocre with plenty of understeer and poor aquaplaning performance, and in the dry the braking distance from 62 mph is almost 4 meters longer than the best on test, which means when the Continental had stopped, the car would still be travelling at near 20 mph! Not the best option for road or track.

2010 EVO FWD Tyre Test - 9th of 9 tyres

  • Negative - Good dry pace
  • Overall - Poor wet performance, lowest subjective score.

Top Kumho Ecsta KU31 Review

Given 81% (breakdown) while driving a Volkswagen (225/45 R17 W) on mostly country roads for 15,000 spirited miles
Some of the published results and comparisons on this tyre are a bit harsh, in my experience of 3x sets and 15k miles.

These KU31's can be bought for c£65 a tyre for 225/45/R17 and to say they would challenge a ContiSport or PilotSport toe-to-toe is unfair - they are half the price after all!

Pros: Cheap, quiet, last forever (my rears have done 12k miles, w/5+mm tread still left!), comfortable, excellent dry grip...
Cons: Grip can be a bit random when 'cold', wet grip not up there with the big boys*,

* again, these are half price, align your expectations accordingly, or spend twice the money! And a Porsche 911 [996] C4S couldn't shake me on a wet March run, so wet grip isn't 'bad', per se.

I'd buy them again and as long as you aren't pretending to be Colin McRae in the wet, you'll be fine.

Latest Kumho Ecsta KU31 Reviews

Given 77% (breakdown) while driving a Skoda Fabia 1.2TSI 77KW(stage 1 to 100KW) (205/45 R16 W) on a combination of roads for 1,500 spirited miles
Had Bridgestone Turanza ER300 before these. They are softer(@2.4 bar pressure) and car felt softer on curves, as opposed to the bridgestones.Upped the pressure to 3bar and roll sensation was not so noticeable,but still there.
BUT: better grip on launch and better stopping power on dry and wet also. Bridgestones needed to be warmed up to give same performance.
Because of the softer compound they are quite silent (at least for the first 1000km). Will update if they get much noisier.
50-120 km/h no noise.
130-160 km/h a bit of noise
180-230 km/h they get a bit noisy, but way less than ER300's.
PROS: good value for money, nice grip.
CONS: Soft sides=roll if pressure

I have never encountered a tyre that slips as much as this tyre - Cant make it for a few hundred meters without the tyres slipping when I press the gas pedal...

Given 44% (breakdown) while driving a Audi A4 1.8T S line Cabrio (235/45 R17) on mostly town for 7 easy going miles
kf: purchased these tires at a discount tire for 60$ each, after 5,000 miles went to get my tires rotated at the same discount tire. While there they tell me that the tires in the front are already at the red line in terms of tread life. and the rear tires are also very close to wearing out. at 6,000 miles the tread is even with the tread bars in the rear tires which were rotated to the back, two extremely close call accidents occured, both times at low speeds turning, once during rainfall at 15mph after constant rain for 5 hours in houston ( not flooded or high water) nearly collided into a pickup.
