I got these tires when I blew one of my previous set Nokian WR D3 and then blew my spare wheel as well after 10 miles so I went to first available tire shop along the road. My Nokians were giving the last of them after 30000 miles and I was determined to buy them again, because they were best winter tires I ever had and performed magnificently, only downside was extensive wear but I made 10000 miles during summer with them (south Europe) - so they lasted well I must say.
So, I got to the first shop and Kumho Wintercraft WP51 were all they had. It was early in the morning, actually I waited in car in front of the shop to open, and then had tires hastily put on and rushed to work. First drive on them was horrible, I felt like I had worst tires ever. But then I found that guy who put them on, inflated them on 3.0 bar !!!!! ( Fiat Croma is rated 2.2) so I put right pressure in them and drove them extensively on all kind of roads, and pushing them to the limit. And I can say this - 1). they are most comfortable tires I ever had. You don't get much road feedback but once you get into them, you start feeling little finesses and they work well. 2). they perform excellent on wet roads, grip is fantastic and cornering is awesome. 3). on dry, you feel a little skid but interestingly, after 2-3 months, when they wear out just a bit, kinda to get them flat strong on the road, this happens no more and dry grip gets much better. 4) on snow, they are not amazing like Nokian, but not far either. Let's say if Nokian are 10 on snow, Kumho are 8.9 which is more than good, because on ice they are even better. 5) Wear is what puts them on the top, because after 14000 miles, I can see the wear just a little, they are much better than Nokian or BFGoodrich and still, they feel like new. 6) driving them on late April, 15-30 C temperature, haven't seen much difference than driving 2-10C which sets them apart from other winter tires that feel much worse during summer.
All in all, I believe I have one more season and at least 10000 miles on them, if not more.
All in all , these tires surprised me quite a bit, and I would buy them again because, although not 10/10 like Nokians for winter, they are a bit cheaper and give much more back, in terms of durability and usability in different conditions.
Downside is that I have them on T ratings for speed (180 km/h max) and I pushed them to this limit often and for prolonged time on long highway drives and I can say they excelled and passed ever test.
One more note: my set was made in Korea, not in China, if that makes any difference....
I can recommend these tires.
