I m wandering if 225 45 17 will fit instead of the 205 50 17. It is almost the same ratio but i m wandering if 225 will be too large for the wheel.
Thanks

Well, from what tirerack.com says, 18X8 is the maximum you can go....I better not get screwed with this. Hope everything will fit nicely. If not, I know someone here will buy them from me

I have 225/40 18" on my RX-8 wheels. BUT...I think this size is one size too small. The wheel lip is not protected by the side wall.

What about 245/35?

I did a little more research, and I think a 255/35 18 would be a better fit.
But would it rub?

From what you guys wrote, I'm thinking 235/40 would be my best bet. It would protect the lip a lil better than the 225 and would offer enough ride quality without rubbing....I hope...what do you guys think?
The OEM for the RX-8 are 225/45VR18 ...I think that's too high and would create rubbing....

I think I'm going with 255/35 when my tires need replacing, that's what I think.

The 225 is about 1" too narrow, the 255 would add about 1.8" to the width. This would give about 3/8" overhang on each side. Which I don't think is enough to rub.

According to this link, the difference in width between the 205/40 vs the stock 255/35 would be 1.9" (or 25mm closer to suspension than stock). The difference between the 205/50 vs the 225/40 is 1.1" (or 10mm closer to suspension than stock).
But that's without entering the offset, since I don't know it.
If we knew the actual offset of the MZ5 wheel and the RX-8 wheel, we could get a much closer idea of how much clearance the tire will have.
I would be more worried if I had really low springs, as the front wheel is already close to the fender.
