SQUARE wheel/tire fitment?
Hey guys. So I've had 17" wheels for a bit now and I kept thinking I needed 18's. The time has come. I bought my gear. You'll see a picture of them down below.
However, I am not here to show you guys my wheels, but to ask a question. I have been looking at lots of stances or fitments if you'd rather and figured I'd wanna go for something such as "herblenny"'s old setup. (I will also insert a picture).
Problem is, I don't know or am not sure about the tyre size that I would need in order to get a SQUARE fitment to go along with my rims.
(For those wondering) My current setup is:
Front: 235/35/ZR17 with a 17x9 +25 wheel
Rear: 245/45/ZR17 with a 17x9.5 +20 wheel
My FD's new shoes:
SSR 3 piece Professor SP1
Front: 18x9 +24
Rear: 18x10 +24
However, I do not plan (as of now) to get the FEED fenders. I MIGHT get the front ones, but as far as rears, I will only roll the fenders and also pull them a little since 18x10 +24 will poke out about 2.4mm more than before (which is not alarming). (ALSO will put up a picture).
I already have a setup in mind but I still need your opinion/confirmation.
255/40ZR18
275/35ZR18
TOYO R888
Picture 1 (My desired kinda setup)
Picture 2 (Fender example)
Picture 3 (New wheels)
I know both of them are on the forums.

My front wheels are 18x9 with 255/35 tires (similar to what you're thinking of to get). They don't sit perfectly square like your posted Picture 1, but still squarish, this is the only pic I've right now:
They look much better than the previous 235/40 tires which looked too much rounded.

Yeah, square wheel and tire set-up means the wheel&tire widths and diameters are the same as well as the same offset wheels so they can be rotated without any change.
I think what you are saying is you want the tire sidewall to look square on the wheel- none of the stretch look.
Is that correct?

Do you think 255/40 would make the sidewall perfectly squared? By rounded do you mean there's a bulge or you mean it's almost stretched? Because 235/40 is what I'm running right now on my actual front wheels and it's almost square. Is there any stretch in the 255/35 because by your picture it looks like the sidewall could use A LITTLE more tire. Not alot though. ie: 255/40

Every tire is a little different.
What you can do is measure your rim width (listed width is nominal width from bead to bead) and compare to tire's listed "section width" and "tread width" on the Tire Rack.
If you can get the section width, tread width and rim width to line up you have what you are looking for.
Also, tires with a rim flange protector have a lot more chance of looking square versus looking round because they don't suck in toward the bead area.
Tires with strong sidewalls and flat tread surface instead of rounded will look more like you want as well. You are going to have to Google search to see how the tires look mounted.
Interesting detail to obsess about... enjoy.

I don't think 255/40 would look more square than 255/35 in my case, it will just make the sidewall bigger which in turn will tend to appear bulged. But I agree with the above post that each tire is different and that it also depends on how strong the sidewalls are.
by the way, I'm using this calculator to measure my wheel/tire combos every time I'm to buy new wheels/tires

I meant stretched (not bulged). It's strange that 235 tires looked almost square on your 9 inch wheels. Are you sure they are 9 inch wheels though?

They seem to have the strong sidewall you are talking about. As from what I've seen on images.
That's mainly why I wanted to go with them in first place.
I am going to measure just like you said, will give me a good idea about it.

Front is 18x11 +45 with 295/30-18.
RX-8 isn't my daily because it gets horrible gas mileage (auto rotary) and I have a Mazda3 that gets literally twice the mpg.
Other than lack of power and gas mileage I absolutely love the car. Better chassis than the FD in terms of handling/dynamics.
I also love the fact I can fit all four 18x11 w/ 295s in the back seat. I can't fit them in the FD.
I recently moved and had a huge box that was too long to fit in the back of the F150. No problem, I opened both doors, layed the seat back and stuck it in the RX-8.
