Hello, Since the Mr._Nielsson and the switch selector have strangled the other treat quite quickly without a meaningful title, I ask here again: Do you have to exchange all four tires if the profile is too uneven in order not to accept consequential damage to the distribution gearbox? It is about the following: I deliberately did not buy a BMW 5-wheel (X-Drive) a few years ago, as this was exactly a problem. If the profile depth front axle to rear axle was too large The difference could have been caused by damage to the gearbox. Are such damage also known to the CX5? Small note: I had an accident on my Golf 4, in which a rear tyre was destroyed. When the vehicle was repaired, only one tyre was replaced. The other one still had about 50% profile, I had to pay for it myself. The new tyre was even another manufacturer, as the same manufacturer was not available.
