Tex, I vented the tread face in 2 spots 180* apart. I'm going to plug the rim vents with silicone and see what happens. I figure what gets in the tread vents will be closest to the exit vents, so it may work out fine. I made a punch out of a small brass tube (about 2mm, about the same as the Proline holes in the rims) that I filed to have a sharp edge. It punched out the holes very nicely.
