Car kia cerato 4 20 g. Compare with pirelli p7 I drove them for the first 1000 km, mostly on bad roads. Hernias and cuts are not observed. Feels all holes. Pretty soft. On rough pavement it is noisy, on smooth pavement it is generally quiet. It manages well, but during the break-in, the roll was felt, probably due to the soft sides, now I'm used to it, everything is fine. Wear is not yet clear. Personally, my opinion is that for 20 thousand, rubber is the norm, especially in our time! I recommend.
