terrible noise after 90km, hissing howl is difficult to describe, good bmw noise they slide relative to the center, and the inner part of the wheel and the outer one slide unevenly, you run into a bump, a hole and again wild vibrations from 80 km / h, you have to remove the tire and put it on the disk for a very long time, but it was never possible to do this ideally, the tire fitting shops were good and different, in different cities of Hong Kong, Hong Kong, Hong Kong, not a single tire shop could put them in, everyone concluded that the rubber was guano. the tire slides relative to the center by 2-3 mm, and each time in different ways. I tried to put the same size on other disks from x1, the situation is the same, by the way, my disks are perfectly even! Another minus, it whistles in corners (pirels and bridgestone did not whistle better), brakes noticeably worse than bridgestone potenza s001, abs works, steering became blurry reaction to sharp maneuvers blurry compared to bridgestone potenza s001, but this minus is covered by the plus that the pebbles are cracked rails and other passing became much more comfortable.
addition 09/13/2022:
period of use is about 2 months, mileage is 7000 km, there were no collisions with stones, rails, pits, so that a hernia came out, rails and pits are driven at a speed of about 20 km / h, or even slower, the clearance will not allow you to drive faster, a hernia crawled out on Hong Kong city roads , there are no holes at all on the route!. A hernia on the front wheel came out, there are no marks on the disk that speak of a strong blow or any kind of blow at all (perhaps a crack in the cord received on the Hong Kong roads gradually spread - 2022 km ago, unless of course there was one). On the Pirel they flew into the pit at 120 km / h, no hernias slightly bit the rubber disc.
during emergency braking, a very long braking distance whistles compared to bridgestone potenza s001
