Stock rim width --

I'm finding conflicting results. Are the stock 18" Rims 8" or 7.5" wide? (07 if that matters...) Thanks in advance.

I was going by the tirerack. If you put in Mazda Rx-8, all of the wheel selections are 18x7.5 That's odd if they are 18x8, that's all...

They do that because 7.5" wheels will technically work with the stock size tires. They just want you to have a broader selection because that means, to them at least, that you are more likely to find something you like.

It's marketing.

Rim size

Straight from the Mazdaspeed brochure (I work in a Mazda dealer) - the Mazdaspeed wheels that are available in the US are 18x7.5 and are 17lbs a piece (They look similar to the T5 wheel on the Mazdaspeed Ver. 2 in Japan).

Why the difference from stock width I have no idea, it can not save that much weight.
I know the narrower the wheel better the snow performance....but who is going to drive the Mazdaspeed wheels in winter?

something jedi doesnt noe... the force has not always been with him. :-P

Yea i was surprise to find that out too, like a year a go though. Basically that is the only thing that saves weight, too many spokes and forged magnesium cancel out the weight difference.

Stock RX-8 Wheels are 18*8 or 16*7.5

ALL Mazdaspeed wheels specifically designed for the RX-8 are also 18*8. This includes the ones that are on the Mazdaspeed Ver.2 Concept car. To be fair you can get them for the Mazda 6 in 17*7 as well.

The only 18*7.5 wheels you will find from Mazdaspeed aren't even meant for the 8, but the 6. These were part of a special "mazdaspeed" package in canada that some of the dealers were putting on the 8s when they arrived nothing more. Those wheels are called the MS-T II and aren't the same as the ones on the Ver2 car.

Ja, 17lbs and 7.5 no way.

I think Juice has clarified the mistake.

What's the weight on the MS-T II rims that came with the "performance package" with the Canadian models? I've looked everywhere, can't find a price.

I think you guys are all talking about the Mazdaspeed wheels made by Rays for the Speed3 and Speed6. They are 18x7.5 forged and weigh something like 16lbs. They are like $450 a piece.

Stock offset for 18*8 is +50. I have no idea what the offset on the 16*7.5 rims is.

Not true. They are between 20.5 and 21 pounds, depending on the regular 18x8 wheel or the shinka 18x8 wheel.
