I have my c55 rims up for grabs

But what does the offsets influence

The rims im interested in had offset of 35 front and 35 rear

Ive heard stock rims are 30 offset front 34 rear.


Thank you, and as always appreciated!

Offset is the distance in mm from the center of the wheel to the hub mounting surface (the part of the wheel that is in contact with the hub). Assuming you are sticking with the same wheel width as your stockers (and that 30 is the correct stock offset, I don't recall...) then the new wheels would be 5mm closer to the suspension in the front and 1mm closer in the rear.

Thanks a lot man, i wasnt sure if it was 5 inward or outward

Would i need spacers?

Thank guys like FrankW and phister, they enlightened me with their knowledge I don't think you would have a problem with an et 35 front if you are sticking to a 7.5" wheel, my 19x8.5 et32 fronts have 15mm less clearance to the shocks than a stock wheel and I have no issues, but I am not lowered. If you are going wider than that you may want to check in on the W203 forum https://mbworld.org/forums/c-class-w...-know-285.html or if nothing else, crunch some #s here... http://www.1010tires.com/WheelOffsetCalculator.asp

Which wheels are you looking at?

THey are five spoke amg rims, but they are the rims that came with non-amg motor cars, but the amg package.
The front is 8.5" the rears are 9.5"

Thanks a lot man, again I appreciate it

SL 55 rims are perfect fit with 265 rear tires or 275 with fender grinding. mine are 18x8.5 ET 30 and 18x9.5 ET 35.

Glad to be whatever limited assistance I can. With that setup you will have 3mm LESS inside clearance than I do...not sure if that will cause rubbing or not. At et 35 rear you should be fine with up to a 265, and from what I have read, 275 with some trimming depending on the tire brand...assuming you stay on stock suspension. Others can correct me if I am wrong. Good luck!

I had 265 in the rear and i didnt like them too much, so i went back to 245.
I guess well have to see when they get here

I just out up a set of authentic amg monoblocks in 18, that's a beautiful setup on that car and works perfectly...

So, reading this can I assume a stock, non-grinded C55 running 18x8.5 ET 35 and 18x9.5 ET 30, basically opposite offsets, equal size wheels, could run 245s up front and 265s out back w/ no issues?

This is at stock ride height and on stock suspension. No coilover perches/hardware to foul the gig up.

Nope, 245's are too tall and will rub on the inner fender liner at 3/4 turn. You can run 255/30 to keep the tires at 35" height to avoid rubbing or go to 235/35.

Here are stock offsets and stock tire sizes. Personally i run a Rotiform wheel w/ stock size tire up front but a 255 in the back with no issues

I don’t believe that information above is correct. First off those are the same size front and rear, the c55 is staggered. I believe the offsets and the model years to be wrong as well.
