Biggest 20" tires? Already searched



I'm going to buy the 20" wheels as my winters. What is the biggest size I can fit on a W164 ML63?
295/50/20?

305/60/20?

I want them so I can go off road and for MAXIMUM COMFORT on the highway (which in Costa Rica they are not the best...), max speed, around 120 on the highway.
My current low profile tires, SUCK!, they are a bumpy ride, and they can blow up with next to nothing.... Please help.
Also please note that thewider the wheels the less comfy the ride quality Will be...
