Wheel/Tire size computer found, is it correct?

245 35 18 - RX7 = Performance car


215 40 18 - RX7 = Daily driver

My 'vert with stock suspension was running 215/45/17 with room to spare. Stock suspension I think I was 235 at all fours.
When I got the coilovers is when I got serious about tire width.

If you're going the non coilover route there is no reason you can't get a square 235 setup. Problem is that the rear is vastly different from the front. So you can run big staggers, and personally, I prefer that look more than the square. The rear is much more sunken than the front.
I MAY be running down with the track trailer, in which case I'll also be bringing the Hoosiers

Hehe. I think my tires are wider on the Cosmo.

The problem is that we're talking about NOMINAL #'s...

One tire with a 225 width isn't going to be the same as another's 225 width.

I've had a pic of my 8.0", +30 fitment with a 215 wide tire up front with stockish (unknown brand spring on GAB shocks - think KYB AGX) front suspension, and I manage to stuff a 6mm (~1/4") spacer in between the tire and the (bottom of) the spring.
If we do the math, a 225 wide tire would basically eat up all the space...

Yes, I've heard of 8.0", +35 spec wheels fitting up front, but I wouldn't risk it from my experience; be prepared to run a thin spacer just in case you hit stuff up front...

Watch out for aftermarket springs, as I know for sure the Tanabe GF210 and Tein's run larger diameters on the bottom coils, which gives you LESS clearance on wheels.
I'd put money these spring + a 8.0", +35 wheel will almost never fit...

Aftermarket coilovers might be a problem, as most will run a 7" height spring up front.
This means for most people that the adjustable lower spring collar will most likely be adjusted all the way DOWN.
Again, this DECREASES clearance...

Realistically, you can run 225's for square fitment.
If you get the (front) offset spot on, you can run 235's.
I find that FC's running close to 300 (or more) can easily overpower these narrow tires with the right foot.
I really like running 255 square, but it's next to impossible with stock front fenders...
I like running 255 / 40 / 17 tires on 9.0" wide wheels; you need an offset of around +20 (minimum) to +15 to get them to clear everything up front.
The problem with this combo is that it'll hit the fender lip!
Wider (fiberglass) fenders are an option (which I don't like) or serious modification of the stock fenders is needed.
This 255 square set-up is fun with FC's running in the 300 - 400hp range, which covers most of the cars out there that are modified.

I think they look great Brian!

Thanks Zach! Fitment was TIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIGHTer than virgin ass

[FC Zach]

To be safe, I'm thinking I'll need to go with a coilover setup. . Shit's close with a stock wheel and I don't want to be pulling fenders, the poke and stretch thing just isn't my style.

I liked the look with 16's I had on my old red FC. It's too bad wheel and tire options are so limited with 16's. I need to get a good picture of the setup on the orange FC: 17x9 +22 with 255/40R17 all around although there's no way that will work with stock fenders.
