OK...this was the easiest ever (about an hour & less than $15):

Go purchase a section of 2" diameter PVC or ABS pipe from your local home improvement store. (I got the ABS since it's black like tires) Since I didn't want to use the wheels that came with my TT-01 (WRC) car, I went to the local hobby shop and purchased "standard touring car" wheels that were 2" in diameter. I also have a mitre box that would help in cutting the pipe sections evenly in 2" wide sections.

- Measure the pipe in sections so that they are just slightly wider than your wheels.
- Use a mitre box to cut the pipe evenly...or rough-cut to the correct width without a mitre box.
- Using a sanding block, sand the edges smooth.
- Sand the outside of the wheels that you will be using so that the new "tire" will stick.
- Press fit the new "tires" onto the wheels and sand the new tires to fit.
- Once you are satisfied with the look of the new tires on your wheels, press them on and use CA and run a small bead of glue around the back-side of the wheel/tire (so you don't see th glue)
- Wait for the glue to dry for a while.

-Mount your new "drift wheels" and go enjoy!!

I got a 10 foot section of ABS for less than $5. (Could make about 144 "drift tires" from it!)
The "standard touring car" wheels were about $9.
