In general, worthy tires for this money, I bought 235 60 R 18 2 years ago for 7000 pieces. If compared with Dunlop Sp 270, these are much softer, besides, Danlop was worn out for 50,000 to the cord, I drove 30 thousand wear on these, you can’t see. As for the noise, it's not the rubber that makes noise, but the stones that clog into the tread, then fly out from there at speed, but not all, as a result, we ride on the "stone spikes" that create this rumble.See full review
