This worked fairly well except that the tubing expands an awful lot and wears down to quicky. We have been experimenting with different ways of getting the same result as the surgical tubing that just doesnt wear as quicky but are at a loss, so we were wondering what you guys have been using on your wheels(if any)?

It appears you are wanting more compression as if you had pneumatic wheels. Why not put the compressible material on your stationary wall opposite the wheel?
