265-35-18 on 10.5" +43 don't rub...so you can make them fit without a hatchet job on your fender liners or pulling the fenders.

Wow... On 10.5" wheels? On all 4 corners? If I run the 18x9.5" +45 wheels with no spacers on the front, the inner edge of the rim scrubs/grinds at full wheel-lock. That's part of why I have the spacers on there.

And yeah, I really did do a hatchet job on my inner fenders, back when I first got the car and was still learning. It's not really visible from outside the wheel well though and it doesn't affect performance, so I don't worry about it too much.

^ If anything the wider rim is working in his favor. Regardless of rim width, the width of the rubber is only factor that matters here, because your offsets are the same and it's not the rim rubbing here we are talking about it is the rubber, determined by the 265 (means 265mm tread width). With the wider rims there is slightly more stretch on the 265 tires effectively making the outside diameter slightly less.

In my case the fenders are rolled and are not an issue at all, the rubbing I would be concerned with is only the plastic fender liners, but I'd don't want to hack mine up, I'd like to keep them as factory provided hence why I bought 255/35's this go around. Planning to try and squeeze 265's on when the time comes for new rubber, but I would probably get a set of adjustable coilovers too so I have more play with camber and ride height to help eliminate rubbing.

Rota Titan 17x9 +42? They look great though I am concerned about brake caliper clearance. Has anyone tried these?

Yep, that was my original STU race setup back from 2007 or so with no fender mods. There was someone that threw on a set of 18x10+50 with 285/30-18 on a bone stock RX8 a few years before I tried and ran that. It should be on here somewhere if you google back far enough. Ride height, camber & toe settings, etc. all play into it. You also have an S2? That might be a little different than the S1.

Here’s a photo from back then that’s on the RacingBrake website, was also an early adapter for their full RX8 brake kit

^ IC, I may have mis-read, at those offsets you are more concerned with the inside corner of the wheel than the outside. See with my +30mm offset it is the opposite, with 265's I'm more concerned with outside edge of the tires rubbing on fender liners.

Rays 57CR 18x9.5 offset

Planning on getting a set of summer wheels/tires this year after i do my brakes. Looking into rays 57crs and wondering if this setup will fit properly. would like a clean yet aggressive fitment, not sure of the tires just yet.

18x9.5 +38 (F/R)

For tires, not sure yet but thinking ventus v12s 265/35R18 on all 4

Keep in mind i dont plan on tracking this or anything, any advice is appreciated!

Not currently, i plan on lowering to remove any wheel gap in the future, not sure what coils to go with as of yet. Looks like new shocks were installed not too long ago

You shouldn't have a problem with that size at stock height. Worst case scenario you may need a fender roll in the rear if lowered but at a 38mm offset you should have just enough clearance to get away without it. If you buy adjustable coilovers you won't need a fender roll for sure with minor camber.

18x9.5 +45 all around
or
18x9 +40 all around

probably 265 or 255 respectively
I'm lowered 1.75" front and 1.5" rear
-1* front and -2* camber respectively
thanks ahead of time

Thank you, I really like these but we shall see how spendy i feel this summer after i do brakes. I was planning RPF1's because they're simple and i do like the look and there are some good deals on them every so often from users here. Thanks for your input!!

If you run 18x9.5 +45 with no spacers, then the inside of your rims (the metal, not the tire) will rub and grind against the steering arms at full wheel lock. Other than this it will work all around (the rear will be fine).

I'm currently running 265/40/18 tires on that exact rims size/offset with 20mm spacers and have no rubbing/grinding anywhere, but I also rolled my fenders and did a bit of trimming on the insides (the fender liners), as well as a small amount of flaring with the hub-mounted roller tool. See my pics above in this thread.

If you run 255/40's on this rim size/offset, you should probably be fine without any significant modifications.

I see what you're saying and it's totally legit - running 18x9.5 +45 wheels with 265/40 tires on 20mm spacers (making it effectively a +25mm offset) definitely caused rubbing and took some modding (rolling/flaring) of my fenders and a bit of fender liner chopping to eliminate all the rubbing. Keeping in mind, granted, that my car is an 11-year-old salvage title, so I'm not exactly worried about its resale value at this point

I've heard it said that RX stands for "Rotary Experiment." This is exactly what my RX8 is; a perpetual experiment, a labor of love, a learning experience. When I pass it on, it'll be to another enthusiast for sure - definitely not a casual

What rims are rubbing? The usual 18X9.5 +45 will fit with no rubbing issues

If you are running 18 X 265 profile tires you should be running 35 aspect sidewalls. The 40's make the tire too big around

Well some rims are shaped different so that always adds some differences why some rub at certain points and others don’t. Having run 18x10.5+43 without it rubbing on the tierod arms then where the wheel edge lands could have impact, such as if it come close where the wider tierod end/adjustment nut is vs extending further inboard where the thinner round extension arm is. Also whether the adjustments are centered properly relative to the steering wheel center positioning, such as if the sterring shaft u-joint was taken loose and then not centered properly. If it’s off on one side then it can crank over more in one direction than the other and cause a problem in that situation too.

^ Fender rolls for sure, more likely a fender pull, probably be scraping the **** out of your wheel well liners up front (most likely will need to remove these), probably going to have to shave or completely remove front side markers. Probably going to have to trim bumper tabs and run a **** ton of camber to the point it no longer handles good and you have less traction than going with a skinnier tire that gives a bigger contact patch. I'm biased I think mega camber is stupid AF.

To be honest, I don't even think you'd be able to fit those up front..... but I'm far from an expert I just base this off of my 18x9.5 +30 setup with 255/35's sitting within stock spec camber where I maybe have room to squeeze 265's on with some slight rubbing on wheel well liners. I'm also lowered, not sure what you plan on doing for ride height but with the right suspension anything is possible.

The rim size isn't the problem, the problem is the 295 width up front, might be into the "burying rubber into the back of your oil coolers" territory at that width. Probably can make it work in the rear but that's out of my realm of know-how.

Secondly, and no offence intended, but if you had to come on here and ask if-and-how to get those tires to fit I don't know if you have the knowledge or skill to make it work; at least not without ALOT of trial-and-error money and HOURS of suspension adjustment. Even then I can't imagine this being a very enjoyable car to drive.

I'm a stock fanatic, which includes preserving handling. It's time to buy a summer set, however there is no much options for wheels, which exactly match stock params, in my country. So, my question is how exactly 18x8 wheels with +45 or +48 ET will affect handling. Thanks in advance.
P.S. I've used search and read some articles, but no good. I suspect the answer would be 'You won't notice', but I would like somebody to actually confirm this
