We're using the pnuematic tires, and they grip so much that we bounce when turning. Our drivers have come up with some creative techniques to work around this, and this system may not be used at all, but I'd like to keep the option open.

Thanks for your help.
there are several threads and one whitepaper about this problem. We wrapped zip ties around the wheels radially and scored them for extra forward traction. This worked fine until Annapolis when a judge (apparently not the real one but a volunteer of some sort) told us we had to take them off (we found something else to wrap them with, though not as good). Subsequently, we witnessed several teams play with zip ties on their wheels so i guess its back to legal.
