These are Privat Fahrens 18x9" rims.

I was thinking of wrapping them in BF Goodrich gForce T/A KDW 2

255/45/18 in the front
285/40/18 in the back



What do you think?

Keep your bullits. Btw they seem more like 16'' than 18'' in that picture.

I emailed Konig/Privat to see if they can modify their Profil wheels to actually fit the GT. I would also like them a little more polished/chrome but I'm not sure what they can do with that. I haven't heard back from them yet though.

SurfnSoCal

They are 18" rims. That pic was taken off of discounttire.com

They are also the correct offset and bolt pattern already, in a black chrome.

Surfn, Nice rims but I would stick with the same width rubber if you run the same rim size front and back. Reason being is your tires with have a bulge at the sidewall on the rears and no bulge up front. IMO it looks dumb. To go with different tire sizes front and rear the best idea would be to find a rim with a 10" rear width and the correct offset. If you look around on discount tire or the tire rack you can find many 18"rims that will fit the '05 Mustang that have 9's upfront and 10's in the rear. My $.02

What offset are you looking at? Everything that I see are 40mm offsets? With a 9" wide rim, that's gonna stick out a little isn't it?

I like those, although the black or gunmetal finish might be cool with he black paint also....hope to see some pics of it after ya switch them out Richard!

SurfnSoCal

Offset is 40mm.

I used the tire/wheel calculator...and 5mm is about .2 inches. not noticeable IMO.

Stangfriik

That's still like 3/4" but I guess that isn't that bad

SurfnSoCal

check my edit. 5mm = .2"

Stangfriik

sorry to keep bugging you but maybe I'm confused on this offset stuff. If I use the offset calculator and plug in 8" with 45mm offset for original wheel then plug in 9" with 40mm offset, it comes to 18mm which is roughly .75" not .2". Can you tell me how you are getting your calculation?

SurfnSoCal

9" wide rim. The Privat Fahren wheels come in 18x8 AND 18x9.

I am looking at both 18x9 front and rear, but putting wider tires on the rear.

But like Rod pointed out, I will get a bulge. So I am re-thinking right now...

but the difference between a 18x9 rim with a 40mm and 45mm offset is a 1.6" wide and 1.8" wide (off where it touched the car, not sure what that part is called. rotor?).

SurfnSoCal

yeah Rod, I just figured. On 285/40/18 tires...on a 18x9" rim with 40mm offset.

The rim is 9" wide. Tire is 11.2". That is a 2.2" difference. So (approx)1.1" of bulge on each side of the tire is alot. Dam...privat doesn't make a wide enough tire.

And those BF Goodrich tires do not come in the right size for...say 275 tires.

while we're on this topic of offsets....again I have a question. is the offset 45mm all around on the 05? I know on my 2000 my back wheels had what looked like a spacer to fillout some of that backspacing.

CanuckStang

Maybe this will clear things up a bit. As you change rim sizes to larger then the offset has to increase in order for the outside edge of the wheel to be in the same spot as the narrower rim. But as you can see with the stock wheels that they are tucked under the wheelwell an inch. So there is room to go to go to wider rims with the same offset. A 9" rim with a 45 offset will only stick out .5" further. A 9.5" rim will stick out .75" further with a 45mm offset, and a 10" rim with the same offset will stick out 1". A 9" rim with a 40mm offset will stick out 5/8" further then the stock wheel.
If you want to go to a 9" wheel and not have it stick out any further then stock, then you need to use a 55mm offset. This way all the extra rim is at the backside of the wheelwell.
Its easy math. Take the rim size and divide by 2. Add this to the offset number, cause offset is measured from the center of the rim in either a positive or negative number.(before you add those to numbers convert mm to inches on the offset. You now have the measurement of the amout of rim that is at the back side of the hub face where you bolt the rim on. Subtract that number from the rim width and you are left with the measurement for how much rim is sticking out in front of the hub. For a stock 8" rim on a '05 mustang with the 45mm offset you have 2.23" of rim on the front side. You can now take any rim width and offset and run these calculations to see if they fit. I would say if the front side of the rim exceeds 3.5" then they are going to stick out from the wheelwells to much.

Hope this helps

Phew!!!! Clear as mud...haha Talking about off set just sets me off. Thank you, please tip your waitresses.

Looks like I will be going to Les Schwab....argggg

I received an email back from them and they said they will be coming out with a higher offset version of the 18x9.5 Profile with the next 2 months so hopefully that will carry over to the Fahrens

SurfnSoCal

awesome jeremy. 18x9.5 would be so much better. Let's hope the fahrens get that size too.
