The rings that Tirerack ships with them say 73.0mm, but 73.1 would be the more common size. I haven't tried rings other than the ones TR sent with them though.
Mine show 5x114.3 stamped near the rim, but it looks like the spacing is 5x100 and the sticker shows 5x100. Maybe they use the same cast and drill them out differently depending on the needed pattern.
