Why have a square wheel setup and different tires? It's not wrong I guess just seems odd.
With stock alignment you may need to roll the rear fenders slightly. |

I agree it might be tight, I just don't have experience to say. But if you think so, maybe go with narrower front wheels too then. I have 8.5 front and 9.5 rear for that reason.

First number is section width in mm. So that's how wide the tire is (not at the tread but at the widest point). Second is aspect ratio. So the height of the sidewall as a percent of section width. Third is rim diameter in inches.
If you have a 225/40R18, it's 225mm wide at the widest point (this is a nominal measurement so can be off a couple mm). It's 225*40%=90mm tall sidewall. It fits an 18in rim. If you have a 235/40R18, the width is the same but the sidewall is larger (235*40%=94mm) so the outside diameter of the tire is larger too. I have 19x8.5 +36 front with 245/35R19 and 19x9.5 +43 rear with 255/35R19. I have Michelin Pilot Super Sports and everyone will tell you I can fit 265/35R19 tires but I had those and they rubbed. I went to 255 to clear stock fenders. What nobody seems to get is that section width is not tread width and that it's a nominal measurement anyhow. Michelin runs wide here. I am on stock alignment, was on stock suspension but now on MazdaSpeed shocks and springs, stock fenders, no issues. |

Front and rear 18x9.5 offset 35 with these tires Nitto NT05 front 255/35zr18 Nitto NT05 rear 265/35r18 Will that work? If it does, will it look OK? I'm looking for a wide look that fills out the fenders without having to modify the vehicle. Thanks |
Thanks Team, took me until the last post to home in on an answer :banghead:
OEM suspension setup and ride height with no intention to lower. I hate spacers but ran 25mm on all 4 corners to see how much i could get away with on stock rims with 225/45 DWS continentals. No rubbing, but it sure looks like it should ! Time for wheel replacements, and 100% agree with staying square. Strongly Considering ESR SR07 18x9.5 +35 with 255 tires on Teams recommendation above. This would seem to result in the same flush appearance as my spaced stockers. Would like to stay with the 45 profile though, to preserve some semblance of riding comfort, unless someone talks me out of it. What do you think ? |
it should be fine, but as far as how close it will be to the fender, you should confirm what you have now, measure to the fender, and then calculate how that compares to what the new setup is.

Front and rear:
18" diameter 9.5" width +38 offset Completely stock suspension setup, and also looking for tire ideas also. This is my first time changing rims so any other tips would be appreciated. |

You might wanna consider a minor suspension drop as well, 18" wheels with low-profile tires look kind of goofy with the wheel-gap that stock suspension causes. https://cimg6.ibsrv.net/gimg/www.rx8...306ddb0cbe.jpg https://cimg4.ibsrv.net/gimg/www.rx8...874aef8475.jpg https://cimg0.ibsrv.net/gimg/www.rx8...a9c559a130.jpg |
Hi all,
I've got a stock RX-8. No suspension/camber mods, rolled fenders or anything. Wanting to change my wheels and my local dealer gave me these sizes as options for the wheels that I wanted. 18X9.5 +22 18X8.5" +30 I've also got recently purchased tyres with this specs 245/40/18. Really looking into getting the wider 9.5 as they will look better but not sure if the offset is enough for the tyres. Is this too aggressive? Appreciate all the help. |

You will have to find about 3/4 inch with camber and fender work... not going to be too easy The 8.5 +30 would fit better but its no wider rim than stock... so you have to decide if thats what you want. 9.5 x 45 fits without much work... so thats about the same outer position as the 8.5+30 ,give or take. I think you have to decide how much work you want to do and start there |

I think you have to decide how much work you want to do and start there Thanks for the info. Unfortunately, 9.5 +45 isn't available for those wheels. You reckon rolling my fender or chaging tyres would be enough to make the 9.5 +22 work? My car is a 2010 s2 by the way, not sure if that makes any difference. |
Not easily.... camber and a heavy roll or pull will do it though. Others have made that offset fit.
You could just find another wheel? Or go with the 8.5 if you don't plan on running bigger than than the 245 tires |
Rx8 fitment
I am looking for wheels for my 2005 rx8. I’m really looking to fill in the gap between the fenders and wheel and I’m having a hard time understanding. I want to run a 18x9.5x38 rim all around and a 245/40/18 tire and I’m wondering if this will rub my car is currently not lowered but I will lower the car after the rims to be flush if needed. So what do you say will it fit perfectly?!?

That size should fit... will likely need a fender roll, but should be close depending on the tire sidewall profile

Its more the tire brand.. some have square profiles and some more rounded.
I think that it won't matter with the 245 tires its more of a problem with 275's |
the taller/bigger the tire OD is the more likely you are to have trouble, keeping it below 25.5” is best
just stating that for the 19” and up wagon wheel peoples ... . |
275/30/19 on 19x9.5 +50
275/30/19 on 19x9.5 +50 all around? OD is 25.5 and the rim will extend 19.1mm more than stock both inside and outside. Will that hit suspension strut? Rub during turns? I don’t want to go lower offset - I have attached a photo of just how little space I have left on the outside with stock sport suspension at full load with 20mm spacers on stock rims with 245/40.

Will Tire be flush
So I plan on running black RPF1s wheels 18/9.5+38 with Achilles ATR sport 2 tire 245/40/18 on stock suspension. I’m worried that the wheel will poke out of the fender!!! I really just want to get the flush look do you think that the wheel will be flush or stick out of the fender and if you have an estimate of how much?
