I'm ordering some steel rims online and I'm getting some conflicting info wrt centrebore size.

It's a 2003 Mazda Protege LX 2.0 with R15 wheels and a 4 x 100 bolt pattern. A lot of the online tools are telling me I need a 67.1 mm centrebore but that seems way too big. Can someone confirm a different size?

 

I just ran out to measure and it looks like they're 54 or 55 mm. I can see rims with a 54.1 mm centrebore so it looks like that might be the ones I want.

 

That's what I am getting here:
Wheel Bolt Pattern Cross Reference Database and Conversion Guide: MAZDA PROTEGE

 

I've seen that, and it does show a 54.1 mm centrebore. But it also shows the Protege only til 2001 (mine is 2003) and R13 wheels (mine are R15).

I've gone out and measured and it seems to be 54.1 mm. So I'm pretty confident with it. Must just be a database/reporting issue for most of the online sizing tools.
