Built from every independent test result and vetted owner review we hold for this tire - the evidence is all further down the page. Data updated January 2025.
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 13 feet 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.

What sizes does the Kumho Ecsta KU31 come in?
The Kumho Ecsta KU31 is available in 1 sizes, ranging from 185/55 R15.
Dry grip and value are the clearest strengths of the Kumho Ecsta KU31 in generally positive owner feedback. Wet grip also attracts substantially more praise than criticism, though some drivers find it less reassuring in rain. Tread life and noise are usually viewed favorably, with later-use accounts including good mileage, but both also draw a sizeable minority of complaints. A smaller group reports increasing noise as the tread wears, sometimes alongside uneven wear. Most returning owners remain positive, while two are less satisfied in later accounts, so there is no uniform ageing pattern. Several replacement-mileage accounts support useful life without establishing one dependable lifespan.

Fitted these tires to Mini Cooper S using 15" tires and they were great. Dry and wet handling is great, especially after the changes to the suspension and proper wheel alignment with proper corner weighting. You could really pushed the car to the limit and when they do understeered, you could really unwind the wheel and it would tuck in again. Great value for money vs performance. Quite playful too, could invoke lift off oversteer with these tires. It hasn't got the outright grip compare to Potenza RE002, but you don't really need it with Mini Cooper S because the chassis with proper alignment and coilover is fun will smaller less grippy tires.

Possibly the worst tire known to man. Had a couple of these now. The previous of which blew out. More recently my Passat developed a horrendous vibration. Turns out the tire's no longer round. It had more bulges than a pant special. Had my car shaking like a defecating dog. Horrendous. Thinking of buying a set? Think again! Buy yourself a pack of rubbers, use them and glue them to your alloy wheel instead. Guaranteed a smoother ride.

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 tire maker know's its good and selling more every day.
I bought these tires 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 tires 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 tires 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 tires 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 tires 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 tire is quite big for a car the size of a 1 series.
These Kumo tires replaced Bridgestones on my Subaru Spec B and have performed excellently. Wear is very good for a car with 245HP and despite being summer tires 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 tire. I have owned the car for 6 years and driven a total of 55,000 miles. Kumo tires were fitted just after purchase and this report reflects my experiance with two sets of Kumo tires.
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 tire, but for anyone looking for something more, i would spend a little more. The PS91 is a much much better tire than these. Handling feels a bit vague too.... on the plus side, these look fantastic on the car - the design is great!
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 tires 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 tire tread blocks having insufficient strength, I'll be replacing them. My advice: don't buy.
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.
I'll keep it brief. Coming from Maxxis Z3 these tires are day and night difference on the road esp in wet conditions. One thing is for sure these tires love high tire 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 tires as a nice budget grippy tire.
i have bought these tires for years and found the price coupled to overall performance is excellent, the only negative i have found is that when the tyers get to about 80% worn ,they feel a tad hard on the ride, but this again informs me through the steering feed back that new ones will be needed soon, dry and wet driving is excellent and fuel economy exceeds fords expected mpg,i feel very safe with these tyers so i will not change brand,
