10" wide wheels up front

[OX1]

@Pentalab - Measure rim width for the 275/45/18 is 9" - rim width range is 8.5 - 10.5
I'm not going to any track days - my car is a car show garage queen and casual Sunday morning drive to Cars & Coffee so I dont think it should be an issue

There will be some bulge with the 9's, but it will be fine for your usage. Taken to the extreme, I ran 275 DR's on my original 86 Capri 15 x 7, 10 holes, LOL!! Not ideal, but also not the end of the world. They finally started making that stock looking rim in 15 X 9's. Still some "bulge", but plenty adequate for street use in a mid 11 second fox.

15 x 7 left, 15 X 9 right.

Here it is still on the 7's, not as bad as you would think, for just tooling around to shows, since this thing was retired from drag racing after I got the Stang.

I'd recommend sticking with 10" wide rims in a square setup with 275's. With that, it's your decision.

This is my son's '08 with 19x10 ET42 APEX wheels with 275/40's in a square setup sitting on Bilstein's and FRPP P springs. OD is 27.7" and fills the wheel wells up like you want to see.

275/40/19 on 10"-wide wheels is a great fitment for the front of an '05-'14 Mustang. I ran this for a while and loved it. To stagger this, a 305/35/19 on 11"-wide wheels would be great for the rear.

I am currently running 285/40/18 on 18x9.5 fronts and 305/40/18 on 18x9.5 rears. The rear fitment isn't perfect but it works.

@oldVOR - This is the EXACT set up I will get if I decide against using 18x9 Bullitt wheels - I really like these Apex wheels (and the 19" Forgestar F14 wheel as well) - thanks for posting the pic - his car looks great

@OX1 - Funny, I had the same set up.
I was BIG into Fox bodies for over 20 years, had over a dozen, so easy to build and race - they were fun, I especially liked the 85's, last year for the carb.

Do any of you guys with the 285's or larger up front have any issues with numb steering or tramlining? I'm currently running a set of 2013 19 x 9.5 base GT500 wheels (44mm) all around with 285's in the back and 255's up front. I'm thinking of going 285 in the front next time around if they fit. The 255's look a little narrow on the front rims. My car is a 2010 GT with 2011 rotors.

Sorry, you can't get those "grey" Bullitt's for S197's anymore, only for new edge now. But these were the style/company I got them from (I cut down stock stang center caps and glued them in). Pictured (above) is 18 X 10/9 set they used to sell. Tires were 295/40 NT05 in rear and a 255/45 NT555 front.

AM still makes these rims though. They call them anthracite, but they are really silver, with a tiny hint of green/blue to them.

@OX1 - what is the size and ET of the FRONT wheel in this pic ??
Reason I ask is that the 18x9 et +30 that AM sells now appears to have a much deeper lip, much closer to the lip on your rear wheels - can you please confirm?

That is an 18 x 8, also AM brand. Pretty sure it is this one.

I use that with a 235, set to like 55 PSI for my "Big & Little" 1/4 mile setup.

I went to 275s all around on GT500 19s. I briefly installed the original 285/255 setup backwards to try the 285s up front and didn't like it. Didn't notice any tramlining but turn in definitely felt numb. That's more a function of less than optimal wheel width for the tire rather than being a problem of "too much tire". A 10" or 10.5" wide wheel would likely return the steering feel to acceptable levels on a 285 front.

I have:
19x10 Boss 302S rear wheels, 285/35/19s square setup. Fits without any rubbing. Track tested.
275/40 18 on AM FR500 18x9 wheels square. Fit no problem, track tested.
No complaints with either setup as far as handling, but wide tires tend to wander on uneven surfaces coming up to lights.
From a ride quality point, the stock 255/35/17 setup is best IMO.
I prefer tires under 27' tall. Taller the tire, the harder the brakes need to work. I find a 26.5 tall tire to be the sweet spot, with the stock 2 piston caliper and the 13 inch rotors.
