18" wheels on an ML63?
 

Guys,

I am tired on dealing with the factory 21's, they are stunning, but made out of butter, they bend and crack and give me all kinds of headaches...

I love having all terrain tires on my G55, I would love to do the same with my ML63, but 20's are still too big, it will rub all over the place.

Are 18's too small?, has anybody run 18's on an ML63?, any advice will be greatly appreciated.

You just need to find something that will clear the brakes. I am sure there are 18's that will fit and ones that wont.

I know 19" fit ok.
