If you drive 60%+ on the highway I'd say 3.73 but with my 30.5" tires I am (over) geared. 4.10's would not only put me right where I need to be at the traps (now crossing @ 5000rpm) but also help with the hills and all the stop and go traffic I am always stuck in!

BTW driving the truck to work again is saweet!
