Power Wagon Registry

I know I've asked about 35's, specifically 315/70/70. Being the Dura-Trac 315/70/17 come in at 34.6ish we are looking at 325/60/20 Dura-Trac because they are at 35.4. Has anyone tried to run these 325/60/20's? There are plains to move to 37's when the warranty is up a couple years from now, and looking the options of tires with 20's.

Thanks!
