curved tire tracks? help

hello all,

 

first, let me say I am amazed at all of the fantastic art work you guys have made.  I could spend all day in awe in the galleries!

Now onto my query...  I would like to make curved tire tracks.  Forgive me, as I classify myself as a novice.  More specifically,   I would like to create an "s-curve" which falls to the horizon line with the tread of a tire visible.

I've attempted to import a fill of a tire tread into a curved line, but that doesnt work out the way I want.

Frustrating as it is, I know it can be done.  what am i missing?

 

Any help would be greatly appreciated.
