dirt bike knobby tire tread pattern

[high impact]

I'm looking for a knobby tire tread pattern for a motocross layout I am designing. Does anyone know where I can find/purchase a vector version? I have been all over the stock sites and I have only found street tire patterns so far.

I don't have the time or desire to make this pattern myself and REALLY NEED to finish this project soon. ;-)

I tried also and had no luck so I made my own. Really easy, I just made two squares inside one another and placed them in the pattern of a motocross tire.
