Re: 32's on an unlifted TJ for a while?
'and the car drove great'? Car? Ugh.
Anyway, other than the fact that you seem to be doing this in complete
reverse order (i.e. gears first, then tires, then lift?)... you
probably won't even find a tire shop that will mount 32's on a stock
height Jeep. How high were you planning to lift in the future (you
didn't mention)? And what wheels? If you don't 'do that kind o
wheeling', the 35c isn't going to be a concern anyway.
Stick with 31's IMO if it's going to be a couple of years before you
install a suspension lift. And like someone else said, after two
years, you may be ready for new tires anyway. If you really want to go
the 32" route, at least install a 2" coil spacer lift (around $130
without shocks). That combination I think would at least be functional
(although I still run 31's with mine).

Yeah, I've been hit on that one before <g>!
It's because I have a manual tranny and when I bought the vehicle, it was
geared 3.07 and that just SUCKED. SO the regearing had utility to me, while a
lift and 33's would have been basically almost unusable with the 3.07's, and I
can't afford to just dump thousands upon thousands into the Jeep all at once...
I've sworn off credit cards, you see <g>!
Besides, i think I did it in the RIGHT order. I don't mind being low-geared,
and let's face it, there's a whole bunch of lifted street queens out there.
Lifted just for looks. I felt I was "getting the foundation right", a lesson
I've leaned before in building buildings on my property.

Re: 32's on an unlifted TJ for a while?
Brian,
I just want to take issue with you on the gearing/tire combos.
I think you're being a little more aggressive than necessary. My own
reading into this and figuring ratios and such actually puts 4.56 w/a
33" tire on the aggressive side as it is. My own experience backs this
up.
I still have the stock speedo gear, so my speedo reflects what a stock
gear ratio with stock tires would reflect at a given speed.
I have had 33s for some time now. Originally with the stock 3.55
gears; my speed was of by a bit, reading 60MPH when I was going
approx. 70MPH.
Now, I have 4.56 gears with my 33s. When my speedo reads 80MPH, I'm
actually going approx. 70MPH. I've flipflopped from undergeared to
slightly overgeared as compared to stock diff gearing to tire size
ratios. So, I think it is safe to say I went beyond the optimal
street/off-road combo gearing, going further toward better off-road
performance, by getting the 4.56 gears with my 33" tires.
Therefore, I would say:
4.10 gears for 31" or 32" tires is perfectly fine; a little better
than stock (except when compared to a stock rubicon with 31" tires).
4.56 gears for 33" tires (4.10 would still work ok for 33s, but i
prefer a slightly improved crawl ratio at the expense of highway
top-speed).
4.88 for 35" minimum tire size. 4.88 would probably work well with 37"
tires, too, but by the time you hit 37" tires, you probably don't
daily-drive the rig anymore anyway, so I'd probably gear higher for
better crawl ratios.
Of course if you don't care if your top street speed would be 55MPH,
then by all means, get 4.88 gears for 33" tires.
It's just that, with my 4.56 gears, my engine is revving at 3000 RPMs
when I'm going only 75MPH or so.
Just my take on it.

Re: 32's on an unlifted TJ for a while?
Brian,
I just want to take issue with you on the gearing/tire combos.
I think you're being a little more aggressive than necessary. My own
reading into this and figuring ratios and such actually puts 4.56 w/a
33" tire on the aggressive side as it is. My own experience backs this
up.
I still have the stock speedo gear, so my speedo reflects what a stock
gear ratio with stock tires would reflect at a given speed.
I have had 33s for some time now. Originally with the stock 3.55
gears; my speed was of by a bit, reading 60MPH when I was going
approx. 70MPH.
Now, I have 4.56 gears with my 33s. When my speedo reads 80MPH, I'm
actually going approx. 70MPH. I've flipflopped from undergeared to
slightly overgeared as compared to stock diff gearing to tire size
ratios. So, I think it is safe to say I went beyond the optimal
street/off-road combo gearing, going further toward better off-road
performance, by getting the 4.56 gears with my 33" tires.
Therefore, I would say:
4.10 gears for 31" or 32" tires is perfectly fine; a little better
than stock (except when compared to a stock rubicon with 31" tires).
4.56 gears for 33" tires (4.10 would still work ok for 33s, but i
prefer a slightly improved crawl ratio at the expense of highway
top-speed).
4.88 for 35" minimum tire size. 4.88 would probably work well with 37"
tires, too, but by the time you hit 37" tires, you probably don't
daily-drive the rig anymore anyway, so I'd probably gear higher for
better crawl ratios.
Of course if you don't care if your top street speed would be 55MPH,
then by all means, get 4.88 gears for 33" tires.
It's just that, with my 4.56 gears, my engine is revving at 3000 RPMs
when I'm going only 75MPH or so.
Just my take on it.

Re: 32's on an unlifted TJ for a while?
I'm gonna chime in with Bob here. If the objective is to get back to
stock gearing for a daily driver, for example in the case of 215/75R15
(27.7") on 3.07 ratio, here's what ratios you would need:
31" (30.8"): 3.41 (3.55)
32" (31.8"): 3.52 (3.55)
33" (32.8"): 3.64 (3.73)
35" (34.8"): 3.86 (4.10)
Granted, bigger tires and steel wheels will add rolling resistance, wind
resistance, unsprung weight, etc. so simply matching stock gearing will
yield a relative drop in power. Going up to the next gear size to
compensate gives the following conventional recommendation:
31": 3.73
32": 3.73
33": 4.10
35": 4.56
If you're hauling heavy bumpers, skids, rack, winch, welder, hilift,
spares, tools, etc. then next ratio may be desired. If you primarily
rally in high range on dirt, one or two up would help. For low range
crawling ability on a daily driver, the ideal solution is to gear
slightly hotter than stock and upgrade to a 4:1 transfer case.
