Hey guys,

I have a 2013 C300 4matic sedan and I have decided to replace the stock 17 inch wheels with 18 inch wheels however I'm having trouble deciding whether or not to get 18"x8.5" 45mm offset all around or a 18"x8.5" 45mm offset and 18"x9.5" 35mm offset staggered setup. The Rotiform SPF I want only come in 18"x8.5" 45mm offset or 18"x9.5" 35mm offset! Basically I want to know the best wheel and tire dimensions for a 18" setup on a C300!

Thanks

well theres lots of threads about this, yes staggered looks cool but you will get more tread life out of a square set up(because you can rotate your tires). 18"x8.5" 45mm offset all around would be best 35mm offset is to aggressive on our cars.

45-54 offset is where you want to be.

I have 18's on my car I went with staggered just for the looks, 18x8.5 43 offset front and 18x9.5 53 offset rear

I just looked online the only option if you are dead set on those rims is a square set up 18"x8.5" 45mm offset all around.

Is there a difference in looks if I stagger the rims vs staggering the tires? So could I get 18"x8.5" all around and stagger the tires.

sorry i just edited my last post and added

you can add spacers to make it more flush on the rear to give it the staggered look, so it lines up closer to the fender.

check your manual it has the tire size for 18's you should get.

remember with 4 Matics you need the same tire brand and recommend sizing, if one tire blows lets say after 15,000km. your probably **** out of luck and need to buy 4 brand new tires just because of the 4 matic system.
(yes its a pain!)

So I could put spacers just on the rear wheels?

pg 59 post 1458 is square set up with 45 offset, i know its a pain but look though as many posts and you'll find lots of pictures of 45 rear offset. It looks to be fine, i personally like to avoid spacers and just get a better offset rim.

I know the struggle to find rims it took me months to decide.

I should add 45 offset on the rear looks pretty good a lot of replica rims come with that offset and it looks good. just look thought the rim picture thread theres tons of people with 45 offset you can see if you like it.

I looked at that post and love how the wheels fit! So even though he has 8.5" in the front and 9.5" in the rear with 45mm offsets thats what mine would look like with 8.5" 45mm offsets all around? Or would it still look slightly different, because if thats what mine would look like I'm totally fine with going 8.5" 45 offset all round!

These cars are a royal pain in the *** when it comes to sizes and offsets lol. I've never had this kind of sizing dilemma with my JDM cars.

I just recently purchased some 20s for my 2017 c300 that I absolutely love!! Problem is that they don’t fit, what are my options here? I can get three of the 5 lugs on but the others don’t line up....fronts are 235/30zr/20 and the backs are 255/30zr/20! What are my solutions? Currently riding on the stock 17s

Sounds like you got a 110 x 5 lug pattern, not the 112.5 x 5 for our MB's. Google "wobble lug bolts" and these might give you enough play to get the rims on.

The solution is to understand wheel specifications and buy wheels that actually fit your car properly. If you can't get the lug bolts installed, then you've bought wheels with the wrong bolt pattern. Sell them and find proper wheels.

Not only is the bolt pattern apparently incorrect, but the tire sizes are off. The fronts aren't too far off, but those 255/30R-20 rears are about an inch taller than your stock tires, which will look stupid.
