I got hired in 4 years my driving style is reasonable. I can't imagine myself at any Finnish stage of the rally. that's the main thing to start with. and for my needs, these wheels came up to all 100. I don’t start with a slip, and I start to slow down 10 meters before the traffic light. for 4 winters, studs were lost: 15 percent in front, 5 in the back. It’s funny to read in the reviews of winter tires that they don’t hold well on the track under 130-140)) the tread clings and rows normally at reasonable and safe winter speeds. wear resistance is excellent, judging by my wheels and my driving style. balanced perfectly on the stampings, and then they stood there, never did the additional balance. I caught nails a couple of times, treated with tourniquets myself, everything is ok. in terms of noise - yes, they are buzzing. the very first departure was reminiscent of the sound in a helicopter. but all the spikes are buzzing, and then you get used to it.
