Attaching Tread on Vex Traction Wheels

[de_]

Since the wheels are glass filled nylon, were rivet backing plates used to stop the rivet from pulling to the wheel or trying to split wheel ?

If no backing plates were used, did your rivets pass fully out of the rim (as per traditional rivets) or were they buried (which I would think would put huge pressure on the holes).|

Also the wheels have support ridges cast into the wheels exactly where ideally the rivets should go. Could grind off the ridge where the rivet would pass through but not happy with that. Else the rivets have to be moved in from the ideal spot. What did everyone else do ?

How long a rivet did you use ? Diameter 3/16 ?
