Had bought me a used but quite fresh pair Pirelli P7, was from the HA of an Audi who has a motor fire in the garage, slaughter vehicle. Anyway, optically on the tires was nothing, also the car was not so strongly affected at the back. Anyway, I installed the at the VA for my rear driven C-Class. On the first ride unfortunately showed vibration in the steering wheel from so 110kmh, which also used during the 2 attempts only from 120 and was already clearly more discreet. I’m not satisfied, so I ordered Michelin PS4 and had it balanced on the same machine, running perfectly. Now I had the idea to let the P7 move on to the HA, the size would be allowed even if the rim is already 8.5″ wide, VA rim is only 7.5″. But now the point, would I have vibrations on HA now or swallow the drive forces this ́way? You also have to know that the P7 ne have really soft flanks, much softer than Conti or the M Idelin.
