If these are the OEM size 20's you were talking about earlier to help improve fuel economy, you're not going to be enthused about either.
I assume you're talking Wrangler Silent Armor.
Dude, I WORK for Goodyear, and if fuel economy was my first consideration, I'd be going Wrangler SR/A's
I had a set of Silent Armors. Dropped about 2 mpg when I put them on. You ALWAYS do with a new tire, because of the tread flex, brand or type non-specific. I wore 'em out. 55,000 miles. Put a set of SR/A's on it, and got about .25 mpg increase. Kinda proved MPG theory, and supported my decision to go less aggressive tread...
Do what you want. But if you're looking for fuel economy, an all-terrain ain't gonna git it...
