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.

Given 57% (breakdown) while driving a BMW 120d (225/45 R17) on a combination of roads for 8,000 spirited miles
Bought these as cheap runflats when the previous owner's Goodyear Eagle F1 assymetrics died a death from sidewall failure.

Initially liked them - I thought the tread pattern looked excellent for water displacement in the wet, but immediately noticed that road noise was worse, especially under braking.

one month in, the water 'chine' tread on the shoulders became severely feathered, causing an awful rumbling noise whenever I corner. It was so bad it prompted me to replace my front wheel bearings before I homed in on the tyres as the culprit! The road roar was especially noticeable when I took the car to Europe on holiday, the super-smooth French tarmac really made them buzz.

I tried reversing them and running them in backwards to un-feather them, which partly reduced the noise, but after putting them the right way around again for the winter they're still unbearably loud - particularly under braking, cornering at low speeds on smooth tarmacked roads.

I have to assume this is due to the tyre tread blocks having insufficient strength, I'll be replacing them. My advice: don't buy.

Given 63% (breakdown) while driving a Audi A5 (275/30 R20) on mostly country roads for 0 average miles
Bought these for my Audi A5 cabriolet. Would never buy them again. They made my car vibrate very much, i tried to re-balance several times with no success. Even renovated my rims and still vibration. Gave up and bought new Bridgestones, the car stopped vibrate emediatly !!!!. Egg-Shell problems with these tires are a fact.

Given 84% (breakdown) while driving a Subaru Legacy 2.0GT Spec B (215/45 R17) on mostly country roads for 8,000 spirited miles
I'll keep it brief. Coming from Maxxis Z3 these tyres are day and night difference on the road esp in wet conditions. One thing is for sure these tyres love high tyre pressures. So if you have a 3400 lb car be sure to run around 35psi, i was at 32 psi and I tell u the difference between 35 and 32 was night and day (subaru). I'll certainly buy again, and I recommend these tyres as a nice budget grippy tire.
