2013 use 1/8 by 1/2 rivets to attach our tread (conveyor belting from a sponsor). we also used a 3m marine adhesive to fill in those ridges and to make sure the tread would stick on well. (for the most part the rivets are for insurance, as the adhesive is very strong) They seem to be holding up very well. Our first set of wheels we only riveted and the treads ripped right off of our wheels.
