I have had 20's on both my CLS550's and just purchased some Vossens VFS2 20's for my CLS63 AMGs... and before I buy the tires (wheels will ship today) I was thinking if the ride sacrifice going to 20's was worth it to get the looks. should I go to 19's.... Anyone running 20's wishing they stuck with 19's?

Ill be running 305/25/20 rear and 255/30/20 Front

Reallly depends what you're after. I'd have a hard time believing that anyone would say the ride quality is rough on 20's, but you're not gonna have the smooth Mercedes feel compared to 19's. The difference will be minimal, but it's there. If you're dead set on 20's then by all means, but stock 19's are perfect imho.

Try not to go below 35 series profile in the front and 30 profile in the rear and you should not feel too much difference.
I had 30 and 25 profile and ride quality took a big hit. Switched to higher profile and now its perfect.
