TL;DR: Overall the tires were fine for a couple of years (~20-25000km).
I drive on the roads of Greece in and out of the city, mainly in a calm pace for gas preservation. I changed from a set of overused Semperit to Kormoran UHP at 5/2020. I scored the tires based on the overall impression and not at how they feel now at the end of their life. At the beginning the tires felt amazing! I used to receive good road feedback and I they gripped very well. I remember noticing that it felt grippier in the wet than in the dry. So for the first year (mid2020-21/0-7000km) the tires were adequate and I was happy about choosing them. The second year (2021->22/7000-19000km) the tires still felt ok, I remember checking for tread wear and I didn't find any observable degradation. In that year I tested for aquaplaning at different speeds and no concerns were raised. In the third year I performed back-to-front tire change. The mechanic didn't observe any excessive wear patterns. However at the end of that year, I noticed I was oversteering at the motorways (2022->23/19000-31000km). Now at ~33500km the tires feel really bad to the point I am very conscious when driving at cruising speeds on roads with consecutive turns. Although they are not completely worn out (the arrow indicator is fully present) some cracks can be observed on the treads as well. To this day the consumption of the car remains at the manufacturer levels, so the tires have not been degraded on this regard. I can't tell about the noise in the cabin b/c my exhaust dampens all other sounds. Also I haven't decided what tires should I fit next.
