I think I may understand what FE is refering to, but I need a confirmation. Bear with me please:
My daughter is learning to drive. We practice parking a lot. There are some parking lots with a lot of my sidewalls left on the curbs. You can see the scuff marks on the sides of my tires -- but it also leaves white concrete residue on my sidewalls. When I was running Goodyear Marathons on the fiver, I would get similar scuff marks, but they would be all the way around the entire circumference of the tire but not in a position where they would be if it were curb contact. It would be from the edge of the tread to about 1" around the sidewall toward the bead. There would also not be any concrete dust sticking to this.
Is this the scrubbing action that FE is talking about?
Or was that perhaps from traveling on gravel roads?
