That second picture you posted is quite telling.
It looks to me as if the rover could have ventured forward a little bit, with that wheel (the wheel up on that rock) coming off the rock a little,
with a portion of the wheel (not the whole wheel) making contact with the soil, while the rest of the wheel remained propped up on the rock. Then
they may have backed up again, leaving that mark behind.
Looking at that image, and the location of the wheel up on that rock, that seems quite plausible to me.
EDIT TO ADD:
I think that is the same image that Zarniwoop posted on the previous page, but his image is an excerpt of this whole image. Between your post and
Zarniwoop's, I think the answer could possibly be that this is a wheel mark.
