For me, they were a revelation, because a friend bought Kugu for them, and I didn’t know anything about this brand at all. And last year, I started choosing tires for my IX35, I asked a friend about Viatti (he had already skated 2 full seasons on them), he didn’t say anything bad, except for behavior in the mud and noise on the track, then here is a model with 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 and not noisy and normal in the mud, just have time to change))) Well, in general, they joked and okay, these are me the criteria did not bother, so I bought it and installed it. Handling and braking are at a good level on different surfaces and at different speeds, grip is excellent even with a slight minus, I tested it in the fall, when there was a rush on the tavern, and I still drove on summer ones, up to -5 the desired properties are preserved. I have not encountered aquaplaning, I hope this figure will remain the same with wear.
