Good Gaffer's tape may just hold but if it starts to unwind, rewrap the tire and put another piece of tape over the end of the wrapped tape that goes over the sides of the tire and then use screws to attach this tape to the tire (don't look at me like that -- driving screws into wheels is a time honored FIRST tradition ;-)

It is a kluge but it gets you running today. Longer term you want to find a way to get a larger, less grippy tire on the center axle. But this lets you get some driver practice in, lets you test out the rest of your robot, and gets you in the bag with at least a direction that you can implement while you wait for your first competition.

Unfortunately we don't have any of this and local stores don't have any of these. So we can't do anything until our competition in 2 weeks. Our mentors are reluctant to changing the actual wheels since that means we would have to take of all our superstructure, gearbox and down to the chassis. Also taking apart and reassembling the chassis would take a fairly long time. Are there any quick fixes we could do for our competition that would be reliable ?
