and where is the skinny tire thread?

Well with that being said would I have to gear over 4.88

4.88 is as low as you can go with the stock axles. So if your gonna regear go as low as you can IMO.

33 & 4.88 is just like stock final ratio

another thing to keep in mind when you start going bigger than 31" tires would be your dana 35 rear end... it can be the weak link in your jeep and 33" tires could put it under alot of strain.. I built my jeep fairly cheaply, and being that your on a budget figured i would throw my .02. I started with 31x10.50's on stock lift and gearing, being that the jeep is my daily driver there are often times i wish i left it like that. you can add an aussie locker up front for around $250.00 as far as bang for your buck this will do more than increased tire sizes or extra hp.. i got bored and added a 2" coil spacer lift and 33x12.50's the lift cost around 200 and i cleared the 33's ok, added a 1" body lift to stop tires from rubbing when i turn. That being said i believe the 2.5" rc lift that has been mentioned would have been my better option. Up till now i had this on stock gearing and the difference between the 31's and 33's is enormous, if regearing is not in your near future i would probably stay with the 31's. If you plan on using that income tax check then you should check out the thread "axles" to see about upgrading your d35.
Welcome to the board, one thing i like about this place is you dont have a bunch of people immediately telling you to check the FAQ, people are extremely willing to give you answers so feel free to keep the questions coming

This is why I've recommended skinny 33's.  There are many advantages and it is less of a compromise then the 32's.  If he goes with 10.5's instead of 12.5's he'll be closer to the weight of his 31's.  If you look on the Skinny tire thread, I have a list of tire specs. for KM2's.  Even though it's for one tire, this should be indicative of other models and even other brands.  The specs show a 33x10.5R15 is only 4lbs heaver then a 31x10.5R15.  It is also 9lbs lighter then a 33x12.5R15.  Roll resistance should be about the same with 31's as the contact patch is going to be smaller for the same PSI.  He's already looking to install a lift as well so clearing 33's shouldn't be a problem.  The power hit between 32x11.5R15's and 33x12.5R15's is about the same. But like I said the the second post, I'd either stick with 31's or go to skinny 33's if I was in his shoes.  For every day driving, it's the best compromise between on and offroad.  More like 80/20, in favor of pavement which is usually less then what most daily drivers do.

As for the Dana 35.  If he's not locked then it's not going to be a problem.  Although it's still not advised to use the fists of ham approach.  Spider gears are usually the weak spot with open diffs.  The axle housing can flex a lot still which puts leverage on the side gears and causes them to crack.

Thanks alot for the input. After reading and figuring prices I finally came to terms that this jeep is gonna be 95 percent highway and 5 percent offroad.  I looked at quadratec's 97 tj build which inclued 2inch spacers with shocks, 15x8 wheels and 31x10.5 tires. I like the look of it. I just dont want to have too much lift and the jeep not look "off"(ie too much lift making tires look small)

Well, you don't really need 15x8's.  You can use 15x6's or even 15x7's.  Actually 15x7's are probably what you want.  The good thing is most Jeeps come with 15x7's.  If you do get new wheels pay very close attention to wheel backspacing.

[jcrockarell9937]

Is it less backspacing the farther ther stick out?

[Jeffy]

Yes.  Stock wheels have 5.5". This usually rubs a little at full turn and when under compression but can be fixed.  For 10.5's you could use as much as 4.75" would be good.  I'd go no less then 4.5" though.

[jcrockarell9937]

Wow the 15x8 wheels I was wanting are backspaced at 3 and 5/8

[Jeffy]

Typical for a 8".  They are normally used for 12.5" and work nicely with 35x12.5R15's and not rub.

[sharpxmen]

yep, i have 3.75 b/s with 33x12.5 and they don't rub in the leaf springs, i had 31s with stock like b/s rims and had to adjust the stops on the knuckles or they would rub against the leafs.

[No Luck]

I'm running 31's on this one regeared to 4:88s puts it right back to stock gearing. bought a cheap 2.5 Rough country lift and put on it. At the same time i put in a HP30 with a aussie locker and a ford 8.8 with a lsd.
