Anything above that, and you really need to look at better axles, sleeves or trusses

Many people are running the stocker on 33/35 tires, and getting away with the occasional snapped CV..
You just have to be real, real easy on the skinny pedal.
This pretty much hits the main points.

so, If I stick to my plan I'll be OK then...

I have 2 sets of rims,
one for wheeling which has 255/75/17 BFG MTs
one for street (light wheeling) which WILL BE 315/70/17 GY Duratracs

Down the road I can upgrade the front axle and maybe sell my upgraded ring and pinion for a few bucks I just need a bigger area to work or a cleaned out garage... right now all of my stuff/gear from my fun trip overseas is filling up a LARGE chunk of my garage... you'd be suprised how much stuff you acquire when you leave home for a year...

Hmmm I am running 31's on the WJ. On the YJ though if we throw chromoly shafts in the D30 it can usually take up to about a 37 inch tire.

I run 4.10's on 245/75R15's, so I'd go at least 4.56's or 4.88's as recommended by others. Also, you are right. There are no 4.27 diffs for our rigs. Since I ran 4.56's on my 4.0L XJ with 32's, I'd go with 4.88's on 33's or higher. It is quite the thick ring gear and small pinion for the D30 though. I'm sure there are thousands of wranglers that have run that setup anyways.
