Tell me about hub bore.

[mndsm]

As everyone already knows, I've done what amounts to endless research about wheels. Juggled sizes, offsets, widths, the whole bit. Now I'm coming down to the last bit of number crunching needed, and hub bore continues to fluster me. I know that the ms3 has a 67.1mm hub bore. Most of the Rotas listed have a 73mm hub bore, which is well, a little bit bigger. I know I won't run into the bores being too small to fit, but what I'm concerned with is the possible issues I could see by running a 73mm bore. I can probably get rings made for it, but that sounds expensive. Can anyone tell me what possible issues I could run into buy NOT getting centering rings for it?

Shake/shimmy, especially at highway and above speeds is the biggest concern by a wheel hub size too large.

The rings aren't generally real expensive to buy, I find it hard to believe you couldn't find a premade set of rings the correct size. I had them on my Mz6 without any issue though some will say even the rings suck and you need to get the correct hub size.

My Rotas have a Subaru hub bore. WheelDude ships them with a set of hubcentric rings no cost if he doesn't have your bore in stock. No worries there.

Since our cars have round seat lugnuts, the rings can just be made of cheap plastic and work just fine, since the lugs actually do 99% of the work in keeping the wheel centered. Really, it's just to get the wheel centered when you're aligning it on the hub. Once you start tightening down the lugnuts, the wheel will firmly center itself.

So I guess the bottom line is, order your Rotas from WheelDude through mazdas247, and don't worry about it :D

When I bought a wheel and tire combo from Tire Rack years ago for my Subaru, they included the lug nuts and hubcentric rings as well. The rings were a plastic composite and they held up just fine. I actually liked the fact that they weren't metal, because they didn't rust or corrode at all.

My Denali has rings for the summer wheels and that is rolling a 22 in wheel. As Jay said the lugs do most of the wheel locating/holding so get the wheels you like and they should give you the correct ring if the bore is wrong.
