I tried doing a search on the center bore diameter of the mazda millenia wheel with no luck. Does anyone know the center bore diameter? I can't get my calipers into the wheel.

 

What calipers? And exactly which wheels? Should fit with no problems.

 

Mitutoyo calipers


These are the 9 spoke Millenia wheels

They fit but I want to get hubcentric rings so that they center correctly.

 

The 9 spoke Millenia wheels are the same offset as the stock R wheels. They just bulge a little in the center which makes it look a little screwed up.

I suppose I could go yank one of the wheels off of my car and measure it, but I'm feeling particularly lazy at the moment.
