And why the size differences between the two tires?
There’s no way to give you gearing advice without knowing what size tires you’ll ultimately end up with, so I’d finalize that before doing anything else.
Most SMB 4X4 conversions run 285’s, and depends what engine when it comes to gearing, some of us have gone bigger to 315’s, but it might take some other modifications to get there, including gearing. My 7.3 started on 285’s from SMB with 4:10, I’m now running 315’s with 4:56, but I’m also towing.
So it really all depends, but if you’ve got a ujor 4X4, they usually are setup with a pretty good lift, I think you’d want some tires to fill in the wells at least a little bit, 285’s at the minimum.
Got a pic of your rig to share?
