Sanding or cleaning tires. If you need to true up the wheels, you can block up the sandpaper...see below
Make up some angled pieces, again with double sided tape, and you can round the edges of your tires
These are some of the uses for this block. If you're too lazy to make your own, email us and we'll sell you one,
but remember, all you get is the need to add all the other stuff yourself
Stay tuned for our Sport version...
