On AC, I had been thinking that too.  Maybe AC and 4:88 gearing with the 31s I have now.   But more likely the 4:88 gearing.  Once I do, my Jeep could forever be sitting on 31s, since i'll get used to the driveability with the 4:88s. 

By the next tire change, I might just stick with 31s for my existing Jeep, then buy a second jeep -- maybe a 4.0 YJ or TJ 5spd that's already built to run with 33s or 35s.

Well, yes and no.  I'd probably do 4:88s on 31s on the 4banger, then get a 4" lift, etc. and 33MTs for next tire change with that gearing, then maybe see if i could, at that point, squeeze a little more out of the engine (electric fan, headers, intake manifold grind)

Unless you're going to do some harder trails you really don't need 33's.  4" with 31's will get you pretty far especially with a locker.  Tuck the transfer case up and add some engine skids and you'll be good.  If you think you're hurting for performance with 31's on there then you'll have a rude awakening with 33's.  The lift will hurt you as much as the tires though.

BTW: I measured my 15x6's.  They're 5.5" BS with a +50mm offset.

Ugh, some guy near me is selling Moab's with the stock tires for $300...  Very tempting!

The harder trails were the idea for the 33s down the road

Then I'd do skinny 33's and not 12.5's.  Most trails should be doable with 31's and some good driving.  33's if you want a little easier time.

Here's some other FAQ's I've found.  Supposedly Ford Explorer/Ranger/Mountaineer wheels have an offset of +12mm.

Here's a list of all makes that seem to fit a Ford Ranger.  They don't say anything about BS or Offset though.  They all share the 5 on 114.3mm (aka: 5 on 4.5") bolt pattern though.  Also, 1998+ 4x4 Ranger's have hubcentric wheels so I doubt they will fit on the Jeeps axles without some milling or a sanding drum as wheels on Jeeps are lugcentric so the center bore doesn't have to be as precise.  I would also think many of the newer cars are similar.

Been browsing POR.  It's funny how you're a noob if you're not rolling on 37's or bigger.  in the picture thread everone is trying to top the next guy. 

Found a pic of a '94 with 31's.  I didn't realize the 6-Spoke wheels were used well into the 2000's.

Yeah, they're 5-Spokes.  The 6-spokes weren't available on the TJ just XJ.

Here's a 6-spoke YJ

4 inch lift and 36's


I found it in this thread. I skipped around a bit since it's a huge thread. There might be more in there on stock wheels.

i like the 6 spoke better. I think they would look nice flat black rather than silver.

Wow, those are huge.

I'm torn between the 5 and 6 spokes.  The 5 spokes would be easier to clean since it's a flush face.  The 6 spokes are a bit more retro.

I've been tempted to go down to 31's since there are so many more choices in tires BUT that's a big jump.

I like the look of the larger windows of the 5 spoke.
