Hello people, after I had joined on a similar topic regarding damage of Lauflächen and no answers came I open here a new one. The damage picture is also similar, as described by mongobongo. The gravel may have caused it, I totally exclude because the picture occurs both on summer bikes and on winter bikes, namely right on the outside and left on the inside. Actually, the flipping could also be excluded. I am a “soft” driver. And if it has happened on slippery ground, there is no damage. There is still a special feature to the tyre damage. With mowed winter bikes (originally factory equipment) a heulton arises during the gelled light braking (entry into the carport). If the summer bikes are mounted, the sound does not arise. For me, only a faulty axle adjustment (also the announcement of an experienced tyre service man) remains. hler” after my memory after a brake service (with brake disc change).
