With my C-Class before, I had the same problem with various summer tyres: SR with mixed tyres and rear wheel drive, front tyres outside round and the rear tyres are clearly more worn out in the middle. VR is clear (curve heater) So now, SR actually go everywhere, only rear (mixed tyres) they are almost blank in the middle: factory tyres Pirelli P7 Cinturato * RFT VR 225/50/R18 HR 255/45/R18 Tyre pressure was always between min and max RFT is hard in the flank Is there no need for the tires to get off?
