Latest Group Test Results

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 80% while driving a BMW 530D M sport (285/30 R20 W) on a combination of roads for 0 spirited miles
Not sure about the wear but I don't care because its all about safety. When I say safety I mean it does grip very well in dry and also wet. I've 290bhp BMW (rear wheel drive of course) and no issue. I dont see why pay double the price for Michelin and other "good" brands. Will definitely buy again but i can see that price is going up. obviously tyre maker know's its good and selling more every day.

Given 77% while driving a BMW 116i (205/55 R16 V) on mostly country roads for 10,000 average miles
I bought these tyres in November 2011 on a deal at £100 for a pair to fit to the front of my BMW E36 323i replacing a pair of 225/50 Pirelli P6000.
The Kumho's transformed the front end giving so much grip the rear would now swing around like hinge every time I really gave it some throttle. Before it would understeer slightly making the rear easier to control but now the front even in winter conditions could be thrown into corners with gay abandonment. At the time the front end of the old beemer was as good if not better than anything I had ever owned with these on.
After that car was retired 2500 miles later I put the wheels and tyres into storage until I purchased the BMW 116i and fitted some brand new Hankook Ventus Prime 3 to the other pair of wheels.
I bought the car at the beginning of summer and fitted the wheels with the Kumho's to the rear of the car figuring it would be better to wear the older tyres out quicker. The combo of Kumho's on the rear & Ventus Prime's up front was awesome. Turn off traction control and I could almost drift the rear of the car around roundabouts as the feedback was excellent and the grip & feel on the front was also rock solid. Come winter though and traction control was a must as the short wheelbase 1 series would constantly snap out on the cold tarmac.
I swapped the tyres around as the Ventus Primes had won the 2018 Auto Bild test and the Kumho's had proved brilliant on my old car. This sorted the handling, you still needed TC but the car definitely handled better and the Kumho's had almost as much grip on the front as the Hankooks.
So to sum up, the Kumho's work great on the front of a BMW as the weight of the engine increases grip and they have great feel on the rear in summer. They tend to snap out easily on the rear of a rear wheel drive car in winter so not suitable for that application.
The only other fault I have is that once the tyres were down to 6mm (after about another 7000 miles, around 10,000 in total) they were prone to aquaplaning. Maybe this wouldn't have happened on the 323i as it was heavier on the front but it certainly does happen quite a bit on the 116i.
These are an old tire now and technology has moved on so I doubt I would buy again, I also have a feeling they may become dangerous well before reaching the legal limit but they were great in 2011 for the price. They may not aquaplane as much on a heavier car, a 205 section tyre is quite big for a car the size of a 1 series.

Given 91% while driving a Subaru Legacy 3.0R Spec B (215/45 R18 W) on a combination of roads for 27,000 spirited miles
These Kumo tyres replaced Bridgestones on my Subaru Spec B and have performed excellently. Wear is very good for a car with 245HP and despite being summer tyres have enabled me to drive through deep snow out of my housing estate while other people have been stuck. However it has to be considered the Spec B is 4 wheel drive with a limited slip differential.The general road handling is superb and in particular wet road driving/brake is so very safe. For example on one occasion I had to drive from Frankfort to Luxemburg in heavy rain and easily maintained a speed of 85 to 90mph. At no time was there any change in steering feel or load, the car just felt safe. On the Autobann running at 140mph the car feels totaly stable which is a compliment to both car and tyre. I have owned the car for 6 years and driven a total of 55,000 miles. Kumo tyres were fitted just after purchase and this report reflects my experiance with two sets of Kumo tyres.

Given 66% while driving a BMW 640d (225/45 R17) on mostly country roads for 18,000 spirited miles
Bald after 18,000 miles is pretty average. The grip is 'OK' average, middle of the road etc. They are a decent enough lower-mid-range tyre, but for anyone looking for something more, i would spend a little more. The PS91 is a much much better tyre than these. Handling feels a bit vague too.... on the plus side, these look fantastic on the car - the design is great!

Given 57% 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.
