Ordinarily, I would just go outside and take a wheel off and measure it myself, but it's pouring down rain. I need to know what the diameter of the bore in the wheels are. The bore I'm referring to is the hole inthe middle where the bearing dust car sits. I need to know so that I can get the proper size wheel upgrade. I know that Mazda typically has three different diamters, depending on year and model. I know these to be 54.1mm, 59.5mm, and 67.1mm. Any light shed on this issue would be most helpful.

 

59.6

59.6

 

WOW, 1/10th of a millimeter. That's all the difference between what I thought they were and what they are. I can't even SEE a 1/10 of a mm. Does it make enough difference that a 59.5 mm bore won't work. I really can't see how that tiny, microscopic differnce would keep a 59.5 bore whell from fitting. But I suppose it does. Has anybody ever tried to put a 59.5 bore on a 59.6 hub???

 

.1 MM = .003937 inches. Can't believe that would be significant. Ckeck if any loosness when put in hub.
