Dudes... You can buy a Ford Ranger with 4.10s and 235X16 tires. 4.10 is not that high a gear, and if anything is still way under-geared for 40s.
Check the chart that Hammer posted. I use something like that all the time myself.
4.56 would be a good compromise for street use. Off-road, even 5.13 are too tall.
With the larger diameter ring gears, going up in gearing (4.10, 4.56) doesn't create as much a problem for gear strength as it does with a much smaller ring gear (Dana 30 - front axle of a Jeep for instance). You have 2 teeth on the ring and pinion until after 5.13.
Can you even drive your truck around town in OD with 3.54 and 40" tires? Seems like it would be barely off idle at 55.
