tires verses gears
 
i have a 1995 wrangler with a 4 cylinder engine. it has 33 inch tires.
would it be better to drop to 31 inch rather than switch to 4.88
gears? i do no do much off roading just some trails

Re: tires verses gears
 
Are you having issues?

I have the tall 3.31 gears in my CJ7 with it's 6 cylinder and 33" tires.

In my case I 'can' use 5th gear on the highway as far as engine power
goes, but it then revs too slow so the engine lugs and it just drinks
gas.

If I forget about having the 5th gear or overdrive as it is properly
called, then my rpm stay about 2300 on the highway or in the 'sweet
spot' for power and my mileage stays over 20 mpg, usually about 23 mpg.

As far as off road goes, I can count on one hand the number of times I
have 'needed' 1st low gear in the last ten years and even then it was
plenty low for the need. I normally start off in 2nd low and cruise in
3rd low off road.

Re: tires verses gears
 
If you feel you do not need the 33's the 31's may be better for you.
All things being equal, smaller tires put less strain on the drivetrain
and it will be less likely to break. The Dana 35c in particular is a
weakness of the YJs.

Wish I had one. Then the 33īs may be fine for you unless you are
having other problems with them.

All things being equal, I'd go with the smaller tire if you don't really
need it. Of course, I just slapped on 35's and only need them to correct a
mistakenly low gearing. Now, I'm even more frustrated with unsat braking.

I would think that putting larger tires on and lowering the rear gearing
would put a tremendous amount of stress on the axles. I have stock 30"
tires and 3.73 gearing, and something tells me that the engineers
matched axle torque capacity accordingly. 35's are huge! I'd bet that
thing's a handful in heavy winds or when trying to brake it down.

My first gear's 5.56:1... The brakes are 11" drums all around and, while
I could live in traffic starting in 2nd, my Jeep's relatively heavy and the
shoes are almost worthless:( Looking at a set of axles to swap, though.
Maybe Bill, Mike and some of the other "old timers" on the group will get
some relief from my annual posts about crappy brakes:)
