There are no tire tracks yet. The rover hasn't moved from its landing spot. The cameras are mounted on a mast. Check out the NASA web site for
details.
It will be some time before the rover starts its journey. Once it does, we should see many fascinating sights. So far, all of the "strange objects"
that people are pointing out in the images appear to be ordinary rocks.
Curiosity hasn't moved from it's landing position, so there are no tyre tracks to see. They are testing all of its systems and scanning the
environment before making a decision about where to go.
