Kumho Ecsta KU39

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.

Overall the tyres are nice. They are good value for money, and feel safe, even if you are driving them a bit harsher, if you know how to control the slip angle of the tyres, in spirited driving. Now, the sidewall is soft, so soft that I had to inflate the tyre over the recommended pressure by 2 PSI. This was to get rid of understeer in the dry. Amazingly enough, the understeer is most noticable when doing slow corners if the tyres are under inflated. On the motorways, the tyres have never failed me or made me lose trust, not even once. On the country roads however... Acquaplaning can be an issue if it is a very wet day, and you are driving conservatively. It was for me at least. For me, this tyre shines on the motorway. The noise is low, the comfort is high. Even in a low profile such as the one in my car. Overall, for the price of tyres, they are not bad. I would get them again if they were on a promotion. I would recommend.

Excellent dry grip for the price. Wet grip is average, not dangerous but will spin up when you put your foot down. Sidewalls are very hard so they are a bit noisey and harsh.
Overall a good tyre for the price

I have bought these tyres to the rear wheels for my 2007 BMW X3 3.0sd (twin turbo 286 HP, 6 automatic gearbox, four wheel drive version) in May 2017. Now, the time is October 2019 and the tyres have been used for 22000 miles since new in 3 summer seasons (mostly from April to November).
GRIP: Dry Grip: Very good overall, but it is not excellent like a Michelin Pilot Sport or Continental Sport Contact.
Wet Grip: Very good overall.
Offroad usage: Satisfactory. I have even used them on bushy, grassy and muddy offroads. Only once I had a risk of staying (bushy and muddy conditions with slight uphill were together), but my X3's electronic systems have helped to go inch by inch! Else they were very good in handling and traction.
BRAKING: Dry and wet : Very safe.
Offroad : Safe enough.
WEAR: Expected life of the tyres are around 30000 miles according to current wear figures. Also, tyres are very durable against unusual knocks created by potholes and bumps (ps: I have used 42-45 psi tyre pressure, recommended tyre pressure of the BMW is 42psi for maximum loaded car, once a month, I check the tyre pressures, and approximately 3 psi loss per month could be faced)
DRIVING STYLE: 80% 50MPH average speed drive (60 mph in German and Austrian Highways!). 1% offroad usage. Around 6000 kms, Ukrainian roads and offroads have been used with extreme potholes, bumps. (My left front suspension has been broken because of Ukrainian roads!)
BUY AGAIN: Yes. They are very good in performance/price measure.

Tyre wall too soft, will bend during heavy cornering
Wear is quite good actually
Tyre started showing cracks early in his life. Will not buy again.
