Answered: Cutting tires

Hi, another question for the forum but this one is about building.
I was wondering if it would be possible to cut the 4" High traction tires, ( http://www.vexrobotics.com/products/accessories/motion/276-1489.html ) And use them as a lining for a joint that game objects would flow through. I don’t know if this is legal, or it is to much of a modification of the parts.
Thanks again!
Nat

Yes, this is legal.
