We made some wheels out of aluminum and glued rubber conveyor belt material ontu it. It's my personal opinion ( and the opinion of several people who visited our pit) that they were among the best out there. I probably have pictures somewhere if you are really curious. We had so much traction that in our high speed gear we couldn't turn well. We made a skip pad on a pneumatic piston that lifted the front two wheels off the ground whenever the driver turned. It's my possible opinion that teams are approaching the maximum amount of usable torque you can reasonable expect from a drive train, and that the limiting factor on power is now almost exclusively weight and wheels. You can't make it heavier, except by using tricks like spams lift up on the goals idea, so your wheels are a critical part. If you can't get glue that will hold, try using something like plastic rivets or high strength fishing wire to reinforce it. Also remember when deciding on a tread examine the feild surface and don't forget you get pushed sideways, not just forwards and backwards.
