The 17s will be cheaper and a lot more available. Plus you will get a little softer ride. A little better for off road because of the ride. Something about low profile tires off road scares me, but I see a lot of guys do it.
The 20s will give it a much more modern look and are probably better for street use. They will handle better. Probably fine for most off road too. But they are going to be more expensive and harder to find.
