5150_C32

Guys,

I have a wheel and tire package picked out for my C32 and I am trying to go with 235 40 18 tires and they state that the recommended size I should run is 225 40 18.

the issue is fronts rubbing and they won't guarantee fitment. 10mm diff

Any thoughts? I am trying to get as much rubber on these rims (18x8.5) as I can.

anybody run into rubbing problems on the front with a C32.

any help would be greatly appreciated as I want to order them ASAP

i have 235 on my Monoblock VI's in the front with no problems. with 265 in the rear, mine rub.

are you running spacers in the front?

cliverman

try 25mm

5150_C32

25MM?!?!?!? That is way too much

I will run 5 at the most....possibly 3

Renault78law

yes, the OEM spacers that come with Brabus wheels, I don't remember the size

typo - 5mm - sorry

I don't have an AMG but I have 18x8.5 fronts and I run 225/40/18. But I have custom made wheels which is why it doesn't rub at all. But the tire size seems fine to me. I have 18x9.5 255/35/18 in the rear by the way

thanks for the replies....I am going to test fit one rim on the front...if it works, then I will have them send the other 3.

what is the front offset? Remember that the stock C32 rear wheel can fit the front in an 8.5 ET34 and a 245mm width, but just barely.

35mm

I am going to try to run a 3mm spacer (for caliper clearance) or a 5mm max

You have two issues at hand. Offset and inside spoke to mounting pad dimension. If the spoke clearance is not large enough to clear the front brake caliper, than a 215mm front tire won't help. Are you most concerned with rubbing the strut tub, the outer fender lip, or the caliper? A ET32 in an 8.5" wheel is the most centered offset you can get. A ET30mm is about as far as you want to go towards the outside, and an ET35mm is about as far as you want to go towards the inside. If the wheels won't clear the caliper, but a 3-5mm max spacer will cure the problem, you are within the range of offset numbers for the wheel to work. It also depends on how low the car sits. In stock ride height form, you should not have a problem. Lower the car about 2" in front and the 235 tire with a 3-5mm spacer will probably produce a cut in the sidewall caused by the fender lip inside edge. It also depends on the tire you are going to put on the car and the shape of its sidewall. A Goodyear GSD3 rim bead protector and side wall stick out 3mm farther than an equivalent sized Rosso, Toyo, or Dunlop. Let us know how everything fits.

smgC32,

excellent post...this is the info I was looking for. thanks

I have a 3mm and 5mm spacer (and lugs) coming with ONE wheel/tire setup (all are 18x8.5 anyway) to test fit on the front and rear. I really hope the setup works as the wheel looks very nice and the entire package was very affordable.

I will definitely let you know how it goes.
