They were a revelation to me because a buddy had purchased Kugu for them and I had no prior knowledge of the company. And last year, when I was starting to choose tires for my IX35, I asked a friend about Viatti (he had already skated two full seasons on them), and he didn't have any negative things to say about them aside from their behavior in the mud and their noise on the track. So here is a model with an indicator a/t, and as for me, so for mud - m/t, and for the track - you need a highway, then everything will be fine Well, generally speaking, they made jokes, and well, since I met the requirements, I didn't care, so I bought and installed it. Although the grip is outstanding even with a tiny minus, I tested it in the fall when there was a rush on the tavern and I still drove on summer ones, and up to -5 the desirable qualities are kept. Handling and braking are at a good level on various surfaces and at different speeds. I don't think I've ever aquaplaned, so hopefully this number holds true over time.
