Not sure, but this may help. I'm running 2000 (I think) 15" Chrysler Cirrus steelies on my 2005 base Vibe. The Chrysler center hole is larger than the 05 base Vibe, so hub centric rings should be used. 56.1mm - 54.1mm, I think. I haven't put the rings on mine yet, seems to drive fine without them. I plan to put the rings on this Fall when I change tires.
