The wheels are HRE 547 Polished finish

front = 18 x 8.5 ET 37

rear = 18 x 9.5 ET 27

tires I want to put on

front = 235/40 ZR 18 or 245/35 ZR 18

rear = 265/35 ZR 18 or 275/30 ZR 18

spoke to HRE and they suggested 235/40

and 265/35 for the rear....but ....Im looking

for an extremely aggressive stance but no

fender rolling

Tire sizes for 18s have been debated many times...

The BEST tire size combination for your wheels are: 225/40/18 & 255/35/18 because that yields an overall diameter that is most comparable to factory specifications.

If you want a wider, more aggressive stance, you can opt for a 235/40/18 & 265/35/18 (this is what I used when I had 18s). This combination will work just as well, but the above would be a better fit.

I wouldn't suggest using 245/275 combination... that is quite wide, and not a good choice for our CLKs, especially since you have your car lowered too.... it might have been ok if ur car wasn't lowered, but it is, so... I wouldn't suggest it...

Also, I'm a little concerned about your rear wheels having a +27mm offset... that is quite extreme... Were these wheels custom made for a w208 clk? cause at that offset, I have a feeling it is gonna rub like crazy inside and may hit your rear axle/axle bolt...

you should have gotten a wheel with +35 offset....

for my 18's, i got 235/40/18 & 265/35/18 and it manages the aggresive look without any noticeable fitment problems

mmgrad wouldnt a 35 offset make the wheel lip go in further than a 27 offset. I thought with the wheel being 27....only 3mm lower than stock it would of made the wheel stick out that much more not the other way around hitting the axle bolt.. I could be wrong but the lower the offset the deeper the lip and may cause rubbing of the fenders instead of the inside. Dont know if Im explaining this too well but are you sure that 27 wont be good the wheels were made for a CLK 55

mmgrad

you may want to call HRE again and double check...

yes, factory rear wheels are +30mm offset, so, by measuring JUST the offset, you are right that there is only a 3mm difference..

But, don't forget that the factory wheels are only 8.5" wide... given that the HRE wheels are 9.5" wide, you have to add another 1/2 inch on each side of the central point...

therefore, you now have an offset that is at least 13mm different (half an inch is about 10mm)...

by having a smaller offset, you are essentially mounting the wheels closer to the inside... so careful...

lou430

OK now I understand what you're saying now that us cutting it close...I actually called HRE and spoke to Chuck there and he confirmed that the offsets will work. They were slightly different from their specs. but not by much.

mmgrad

i think the 27mm may work... it just sits closer than I'd like it to be...

I find that most wheels with an offset of 35 +/- 2mm works best and are typically most trouble free...

but, since your car isn't lowered that much, it shouldn't be much of a concern... hopefully...

Yeah, what he said!

I have the 235/265 combo and it works fine. The 245/275 did not fit even before I had my car lowered.

lou430

they dont look like they sit so close by the pic but I do see what your saying

mmgrad

oops... damn, I keep on confusing myself...

my bad, a +27mm will push the wheels further towards the outside of the car, not inside...

damn it.... lack of sleep... sorry...

so, essentially, if you look from above the wheel, you will notice that the wheel/tires will stick out the fenderwell a little... enough where if it was lowered, your fenders may be sitting ON your tires...

lou430

thats what I was trying to say but couldnt explain to well but dont worry you're still teh man with all the anwers.

Thanks

Lou

mmgrad

hahaha... thanks for the props.. but you are the one sitting on HREs...

I'm still rolling on stock AMGs... well, stock on a CL at least...

Looks great Lou430.
