Hello I drive a Mitsubishi Carisma with 215/40r16er4 mature and have since about 5000km after the assembly of the new tires (Kumho Ecsta SPT) on the rear axle on the inside of the tires found a saw tooth formation. I noticed it as the mature getting louder and louder rolling noises. With the old tires ( falken ) there were no problems. Now my question can only come from the tires or is there often something different broken, since I do not just a few new Rei The car has front drive and H&R springs (35mm) with yellow Konis verbaut Would be happy about a few tips. Gruss Sascha
