It doesn't make a huge amount of sense to use the pulleys as hubs for small OD wheels if you have the ability to hex broach something... but if you don't it's not an awful way to do it (relatively low cost and weight).
Quite a few teams this year made wheels with this tread and loved it. |

Just cut to width and stretch over the wheel. We had lips on either side to retain the tread. These worked fantastic and the wear was nothing compared to Green Banebot wheels (we didn't have Orange to try). Just be sure to clean them in between matches. These collector wheels went through 2 regionals, champs, IRI, R2OC and are perfectly fine. We did replace the tread for IRI but we didn't need to.

Anyone have any tips for cutting the polyurethane cleanly?
