Wheels-Tires Factory Wheel Weight?

[MOD5OH]

Hello,

With winter approaching, I want to start looking at wheels and tires for the s550 as it will be garaged. That being said I would like a lighter wheel if possible. Has anyone checked to see what factory wheel weight actually is?

I have no Idea what the factory wheels weights are, that being said there was no appreciable difference when I switched from the factory 18's to an aftermarket Niche 20" wheel
