Cutting treads for more traction should probably warrant testing similar to how AM did their traction testing this year for the new treads. I bet the extra stress would decrease the life of the plastic hex bore in VEX's Colson wheels, similar to the original 4" knobby VEX wheels with the plastic square broach (or the large green VEX gears before there was a metal hub option)

Remember, VEX's Colson wheels have yet to be tested in live, repeated defensive pushing matches. IMO spares are a good idea for this year.
