Ive used kumho ecsta, ku36 & ku39 and found them great value. Great grip up to 8 or 9 tenths but push harder & they start to lose grip. Great in the wet too. They were very comfortable & quiet which made long jrnys much less tiring, this is mostly down to how soft they are specially in the side wall compared to other brands so not the most durable (15 months or 12000 miles on average), the tread lasts longer than the tyres grip so it wud still get through MOT but had lost a lot of grip by then. Just had these new HS ones about 150 miles ago so not really pushed them yet but these initially felt even more comfy & wet & dry felt very good..seems to have faded slightly already but cud just b me pushing them without realising it...will update this review once I've had a few more hundred miles & motorway jrnys. Once fully bedded in (100ish miles including motorway speeds) will push them in the corners too.

Have these on an NA MX-5 following Owners Club recommendation. Superb upgrade to the budget tyres on the car when I bought it. Would thoroughly recommend the Kumhos as a mid-range tyre - albeit ones that arguably match the Bridgestones on my daily runner...

Ever since I installed this two fresh tyres on the rear, were horrible on dry grip. I felt like I was driving on the jelly... wobbling, and like I was rolling on flat or very bad suspensions problems. Probably because of the small weight of the car, but I have not experience that suicedal feeling in 6 years since I have this car with Hankook Ventus, Bridgestone Turanza, Yokohama Advan, Michelin Alpin and Ecsta KU31.
basically after each curve I'm all of the road... NEVER buy this again!
P.S.: Before that I had, on rear, some second hand ECSTA SPT KU31, despite the awful noise, was superb on feedback and handling..

Excellent tyres, there are many options available for my van but these were the only good ones, I didn't expect too much but they exceeded my expectations by far! The van handles much better now, also the load and speed rating are much higher that competitors. Would buy again!!

Following a double blowout in my MX5 (caused by a pothole), I needed a new pair of tyres quickly. I've been happy enough with Kumho tyres in the past, so decided to give these a go.
Fitted to the rear, the handling felt dangerous, lurching sideways like running on flat tyres. Upping pressures made no difference. I honestly thought that the suspension must have been damaged by the pothole!
Swapped to the front axle, the lurching ceased, but now the steering felt dead! Not impressed...
Grip levels were actually good, but I simply cannot recommend these for an MX5, which has finely balanced handling sensitive to tyre choice.
A set of Michelins has since been fitted - car is now stable, predictable and responsive.
