Gears

Planning for the future here, but looking into gears. Not sure if I am right on this thinking, but here is what I have figured out.
For my 285's: Gear range of 4.45-5.29
For 305's: Gear range of 4.88-5.38

With that being said, my plan is to eventually get bigger tires. Looking at the above ratio's, I could go with something like a 5.13 gear, and be fine with both sizes of tire. Incase I am able to get gears before I am able to make the mods to squeeze the bigger tires under the truck.

What would be ideal gears for a trail truck, with larger tires?

What would be ideal gears for a daily driver, with larger tires?

I know all about the ratios for 2nd gens. Optimal would be 4.10s for 33s, but if you want a taller gear for towing or offroading 4.56 works well. Just lowers you highway mpg a little.

I already have that prob, with that new lift it wiuld be nice to have 4.56's

I used a little gear calculator I found on some offroad website and it said 4.7 so I'd say 4.88s probably.

Here's the guy I wanted to here from. What gears will give me a stock ratio with 33" tires and a 3.4L v6? 4.56?

Simple ratio and proportion problem, (factory tire diameter)/(factory gear ratio)=(new tire diameter)/(optimum new ratio)
So factory tire diameter is 30.6 according to BFG for the stock 265/70-16 rugged trails and factory gear ratio is 4.10 the new tire diameter 33.1 according to goodyear so
(30.6)/(4.10)=(33.1)/(new ratio)
new ideal ratio is 4.43:1 closest thing to that is 4.56 however this does not take into account the added weight of new tires plus any added weight to the vehicle such as bumpers, sliders, skids all that is prolly an extra 500-1000 LBS so I'd say for ideal hwy driving 4.88 would be your best bet. But if your truck no longer sees daily driving duties then I would go as low as possible IE the 5.29s because offroad lower(numerically higher) gears are better not to mention is is likely that tire size will increase at some point if you continue to wheel the truck.

The only factor left out of his equation is the lack of said gun actually on him at the time. If he trys that crazy shit in Alto we can just push him down to the bottom of a mud hole like a out of season duck shot by accident...lol

That's my hold up. It is my DD right now. I am hoping in another year or so, I'll be able to get another vehicle for the daily duties. Sounds like, I should probably wait on any regearing until I have more of a future plan. Ultimately this will be strictly a trail rig. For now, I have to drive it everyday. That ride is getting rougher and more expensive everytime I go offroad.
