any info would be helpful
thank you

I'm running substantially wider tires on both the front and rear on 17x7.5 and 18x9 on a SRT6 (which has larger rotors than a base/limited model). As another datapoint, the SLK320 could go as small as 16" wheels all around.
For the fronts -- 17x7.5 will fit no problem as long as you don't get the offset on the wheels too far inwards. There is a bolt on the upper control arm that can potentially rub if you go too wide / too far inwards. I matched the factory offset (ET35) and with my 245/40/17s I still have 1/4" of clearance.
For the rears -- I run 18x9 ET35 on 285/30/18 and I have plenty of clearance on all sides. I do run a 10mm spacer to push the wheels outwards, but that is because for autocrossing I need to be within 7mm of the factory offset. There looks like there is more than sufficient rotor clearance to go down to 17s without an issue.
terrific link. great! am trying to learn if there are 16" rims that fit the xf and then tires that are same outside diameter or as close as the original (and not wider), so also the car has same height .
after all, it is an R170, that has 16" rims.
the purpose is to increase the comfort. cars with typical wheels have larger soft sides, that work as shock absorbers the old fashion way.
and am more into confort than sharp corners at speed. (where i live there are no roads with sharp curves anyway).
from what am learning, even if ours has many of the features and parts of the r170, there is a big difference in wheels. we cant use theirs. or at least, i havent found the parts that allows us to do so.
so, this is following the quest started at this thread, but for the specific purpose of increased comfort.
the idea would be to find 16" rims and then find tires that have the same outside diameter of the originals.
otherwise we are at a dead end.
but from what i have learned, if aiming at softer ride, seems that softer shocks is the answer.

I went to smaller wheels to save weight and also pushed the aspect ratio down and the width wider, so it effectively lowered my car and gave me more rubber.
For me, my priority was getting more grip for autocross / track, so comfort was not my priority. SRTs are also inherently a much more firm ride -- if you want comfort, I would recommend upgrading to Koni Sport shocks which allows you to dial the rebound dampening.
I bought new rims and tires. The fronts rims and tires are all set at factory specs.
In the rear I got 18x9 inch rims with a 35 offset.
The tires are 255/40/18 - which *exactly* matches the diameter and width of the stock 19 inch tires.
My questions are...
Is it necessary to use 15 mm wheel spacers to get the correct the poke and make it closer to the 22 offset of the OEM rims?
We're talking about just a smidge over a half inch of difference here.
Is it possible that it would it rub on the inner side?
Would there be a noticeable visual difference looking from from a front or rear angle of the car?
35 offset is ok with no spacers if IF u have a lip on the rim of 2" for the rear.
Below is the wheel.
Look okay?
It would be nice to keep the same poke and profile. But I see people having ride problems with spacers.
If I did use a 15 mm spacer, could I use the same lug bolts, or would I need longer ones?
Better yet... maybe I could get away with using a 10 mm spacer without having to get longer lug bolts?
1. U have no Lip... so yes u may nees a spacer put the whell (no tire) on the can ck for clearance
2. the lug bolts are tapered,,, mercedes wheels uses ball
3. to ck your bolt length put a bolt into rim (OLD RIM) see how much sticks through then do new rim now u can tell the length of the bolt,
(add spacer thickness to your measurement )
The only issue I have using Mercedes wheels is the center holes are 75mm, and no one in the industry uses 75mm wheel caps except Mercedes. Which means you will have to use a Mercedes cap of some aftermarket cap with some other design that may not look to good or matches well with your car.
I choose to get a Mercedes cap with the same exterior color as my car, might as well add a bit of style there. I think in the future, I will try to get a center cap blank and have some Chrysler decal made-up to fit it.
i have been dreaming of exactly the opposite: downsizing for comfort. same total diameter but with rims of smaller diameter. but i dont see any anywhere. seems that the only thing that is different from all the mercedes components in our car are the rims and parts attached to them (brakes and the like).
and wheels like these:

My rims are 18 & 19 inch replicas of the Mercedes 17" OEMs. They are made by VMR in Czech Republic, sold under the Sport Edition name by Tire Rack in the US.
What's cools is the size and offset of these matches the stock Crossfire staggered setup exactly.
SD Crossfire... I just realized I didn't answer your question.
The wheels I got are AMG knock-offs.
Hopefully they'll look as good on my XF as they do on this car...
