Thread: 15x8 +30et and 225/45/15's

Will they fit? Currently running that setup on my Miata, and if I can transfer them over to the B13 it would be awesome.

Do you have coil overs? That will help the rear clear. I'm pretty sure you have to roll the fenders or ride the car very high up. May still need spacers even with the low offset. I guess just try to mok them up and see how much room you have to make and where. Its been done though.

What kind of rims? I was looking at the Team dynamics rims on a Miata website.

I run the same size tires on 15x7 wheels with no trouble. I needed to roll the rear fenders.
+32mm offset is ideal in back, front can go anywhere from +38mm to say +26mm.

I believe you will be fine, but the rear might need a tiny spacer to clear the strut tower. Give it a try.

One thing to note. Your Miata wheels probably have 54.1mm center bore (I think!). Our wheels are 59.1mm. Just keep that in mind. They might not mount at all because of this...

most wheels come with a center bore large enough to fit most all cars with a centric ring, off the top of my head i can only think of a few wheels with miata sized center bores from the factory.

however, if he does, in fact, have 54.1 centers you can have them machined at a machine shop.

^How much you think that would run? I have a set of Rota RB's I'm looking into for my track setup look. The center bore for the wheel is around 73mm I believe.

^I'm thinking I would need something like this to get it to fit centered with the 59.1mm. I can't find what I'm looking for. Some people just slap with wheels on with 5mm and go I if the hub bore is over the stock size I assume.

These are not Miata specific wheels, so not sure about the hub center. I don't actually have the B13 yet, waiting for the guy to get back from vacation so I can offer him $250 for the car.
