Wheels-Tires What size tires for a 18x10/18x9 setup?

Use that to mix and match. It's going to be tough to get the front and rear height the same.

10's are wide for the rear and 9's are wide for the front.
You may be more bound by what you need more than what you want.

Forget worrying about a few millimeters of extra width to generate traction, use high performance tires, drag radials, road racing, summer only etc. A 225 drag radial will provide more traction than a regular tire that is 315.
Typically the worse the treadwear rating, the better the tire.
Considering the majority here don't drive there car daily, treadwear doesn't matter.

As a starting point i'd probably look at a 275/35/18 (or a 265/35/18) for the rear.
I used a 225 on an 8.5 front and it was stretched, i went to a 235 and it's better (a 245 would likely be better), but you have a 9, so i don't see too many scenarios where you don't need a minimum of a 245, but possibly need a 255.

Most likely you are going to need a shorter tire in the front than the back.
And if you go too short in the front, you will need to lower the back of the car to make it look right.

I run 285/35/18 in the back and 245/40/18 in the front

I did add rack limiters in the front and remove quad shocks in the rear.. no rubbing

It is a good looking car and so are the wheels.
But it's also the reason i stand by my opinion that dished wheels don't always right on a fox, especially on the back.
Which is why i don't like the stern replicas. Saleen used 4 even wheels, not 2 fronts and 2 deep backs.
Foxes just look better when the spokes go all the way to the tire.
I don't think it has anything to do with wheel diameter.

In the summer time, i go to the dunkin donuts right across from where you are parked pretty much every Sat/Sun morning.
You're right down the street from me.

Well, i don't go there anymore since it burned down.
