2012 S550 4matic winter tires
The AWD was nothing to brag about, either.
My cheap, aftermarket performance tires were scary in the winter.
So, in Jan2017, I decided to get winter tires and wheels from TireRack.
Night and Day difference in the snow traction.
Painted calipers and white Mercedes vinyl decal - original wheels
Added medium gray decal to original wheel. (Please ignore the scuff marks)
Winter wheels and tires from TireRack. Smaller wheel diameter allows taller sidewall, and lowers the risk of tire/wheel damage from Michigan potholes.
