ECSTA HS52

Coming from Lassa Greenways, this is a definite improvement in all categories, the tyre feels very direct with a nice bite into the corners. It has incredible road feedback giving you a lot of confidence. As for comfort it's not all that noisy, especially compared to the Lassa's, as for comfort they are a bit hard though not annoyingly so.
Some reviews say that they feel a bit of an imbalance when doing 110-130km/h and I can confirm got that as well, though it did clear up as they are driven(broken in).
You do feel the bumps and imperfections in the road a lot(but Bulgarian roads are harsh no matter the tyre really).
First impressions are that this tyre is definitely worth the money, especially for the price point they are at, 50 euro a tyre is incredible.

I bought these tires to replace a set of Goodyear EfficientGrip 1 that were on the car when I bought it (used). I drove the goodyear tires for about one month before replacing them due to age. The main difference between those tires is the fuel consumption. With the goodyears, I managed to get around 4.8L/100km while on the Kumhos, the car needs 5.2l/100km on the same journey.
Dry grip is excellent, I have not hit the ABS in the dry yet. Also cornering is absolutly fine.
Wet grip is also quite good, although I have hit the ABS a few times and broke the tires loose once when having to merge onto the Autobahn from a standstill. They outperform the (8 year old) Goodyears that were on the car before by quite some margine.
Comfort is fine, although they seem to be a bit louder than the goodyears.
The tires tend to get slightly flatspotted when parking for a few days. This causes a bit of a vibration that goes away after driving for a few kilometers. Neither the goodyears or the wintertires that are on the car now (Vredestein) do that.
The wear on these tires seems to be relativly low. I ran them for 15.000km this summer and they still have 6-6,5mm left. They had a bit more than 7.5mm when new. I expect them to last for another 30-40k km before needing to be replaced due to wear.
As I am working in forestry, I also drive these tires on forest dirt and gravel roads. On there, they are absolutly fine as long as its dry but get very slippery on dirt as soon as it gets wet. On some kinds of gravel, it feels like driving on ice when its wet, however thats more related to the kind of gravel (limestone) and not so much the tire. Every summertire I had so far showed this behavior. This part off the review has not been taken into account when rating the tire.

I find them quite good in the dry, even in dynamic driving. The wear is also very good, after more than 15,000 km.
But I'm extremely disappointed in the wet - in lateral support. On changes of surface in turns, or in roundabouts, I have to take it easy on the roads where I ride. So, it's not catastrophic, but it slips where I don't have problems with a Continental (the kumho is supposedly at the same level in the "tests" ).
When braking in a straight line, it didn't bother me.
It's better than Chinese, but I wouldn't buy it again for myself. I regularly and easily reach the limit of grip in corners when it's raining, even when I think I'm going slowly enough, I don't like it.

This tire is definitely a good choice for average users, unfortunately, based on my experience and usage, the tire did not perform well. It provides adequate lateral grip on both wet and dry roads, but it spins easily when accelerating and I do not feel confident when braking either. Probably due to the way it was used or a manufacturing defect, the tire started to wear out after the first season. This was the second season I've run it, and I feel like it's time for a change. The tread is now very badly damaged and I don't feel safe. 26.000 km / 16.000 miles
