Really want to make a tracked vehicle, where to find treads

[brushlessboy16]

I really want to build some sort of tracked vehicle, but I cant seem to find a appropriate belt/track/tread material.

20in length
Approximate 12in track width
Savage shocks(I have plenty)
Going to run 4s lipo, mmm.. dont know what motor yet.
Will use a skid steer braking system with a rear(or would it be called a center) differential.

If anyone has any material that could be used as tracks please let me know. Looking for about 1 1/2in - 2 1/2in wide preferably treaded on both sides
