Were this my truck, only off-road (mostly off-road) with no
significant high speed highway driving, I'd go for at least a 4.56, or
a 5.11 gear. Maybe even more... My Hummer H1 (6.5 diesel) is about
5.35, with 37 tires. With a taller tire you may want more...

Many factors matter, such as what transmission, engine specs, etc. No
one single true or reasonable answer...
