Since my truck has never moved under it's own power yet I can't speak from experience but something a little numerically lower than the 4.89 would be nice for the re-powers in my opinion, like the 4.30:1 number some have talked about.
Just playing with the calculators: even with a 38" tall tire and 4.89s my max speed with the 4BT governed at 2300 RPM will be about 70 mph. I don't need 100 out of it, (and there's no saying the cummins would have the power to move something lower at that speed) but being able to get around 70 without being on the governer would be nice.
I already have the lowest OD that came stock in any of the manuals most people put behind a 4BT, and I'd rather not go giant with the tires for a bunch of reasons, being able to fit in my garage one of them.
