Hey everyone!

I'm sorry to add to the plethora of posts such as this one, but from searching around I didn't find an answer.

I purchased a set of snow wheels with RX-8 measurements (225/50/17 offset: 50) for my MS3. Based on all the research I've done before my purchase, it looked like RX-8 wheels fit Mazda 3s without a problem. Well, I guess its a little different when it comes to the MS3s. I do realize that MS3s have larger brakes than a regular 3, but I never realized that the offset would be different.

When I put on the snow wheel, its center hole seems to be too small for the car's hub; the rim barely clears the studs. Pardon my lack of vocab and knowledge in this area, I never completely understood the science of proper wheel fitments. So basically my problem is that the rim's center mounting hole is too narrow, which doesn't allow me to slide the rim all the way on.

I'd hate to go through the hassle of reselling these now. Are there any adapters that can be used to fix this?

Any help is greatly appreciated!

so the hub bore is different on the MS3, at least I think thats what you're saying. If this is the case, you'll have to have the RX-8 wheels machined to fit

Yep the size of the hub bore is exactly my problem... Now, if I were to get it machined, what measurements would I use?

You said they have RX-8 measurements; are they actually RX-8 wheels? You seem to imply that they're not...

I would tend to think that the hub bore is the same - all of the new mazda's share the same hub bore, RX-8, MZ3, MZ6, Miata - why would the MS3 be different?

Like bearda said - are these OEM wheels or aftermarket?

he has 17" RX8 rims? i thought they were 18"

the hub bore is exactly the same on the 3 and MS3. the hubcentric rings from my standard 3 fit my MS3.

They are not OE RX-8 wheels. They're cheapo after market Kazera rims which were bought as a snow wheel package for an RX-8. Their measurements pertain to RX-8 numbers as these wheels were purchased from Tire Rack.

Any more ideas, guys? I appreciate all the input so far.

well, ideally, you'd have them machined to whatever the hub bore is, which I believe is 67.1 mm, you could also machine them to be oversized for a universal fit, and just use hub rings, but if you're bothering to get them machined, might as well have them be hubcentric. . .

If tirerack sold you those wheels saying the hub bore would fit an rx8, which has the same bore as the ms3, and they dont fit, then it is obviously a mistake on their end. They should send the correct wheels that have a large enough hub bore.

You're damned right they should. I've only heard great things about Tirerack's service, and this should happen no problem.

The wheels were not originally sold to me. I purchased them on ebay from a person who used them for one winter season on his RX-8. From what I was told by him, they were originally purchased from Tire Rack as a set of snow wheels for his RX-8. So getting Tire Rack to fix the problem wont work :)

I think that getting these machined is going to be my best bet. I kindly thank you all for your suggestions!

i dunno if that is the best idea either. it can mess up the integrity of the wheels and you can have much bigger problems than you currently do.

You know something, you're definately better off selling these rims to someone else and get something that fits.
I don't doubt you can find a competent CNC guy to machine your rims to spec, but how often does that happen? Will you weaken the structural ingegrity of the rims? Will they be slightly off, and cause a wobble at speed? Sounds like they're not worth the effort.
