I know this comes up often, so let me apologize in advance for the wall of newbie questions!

Right now I have some sort of spacer lift on my CRD and 265/70/16's. The wheels are stock, and I get rubbing from the front tires on the unibody (from the front of the tires). I'm at 21.5" front and 21.25" rear on both sides from hub center to flare. I have no idea how much higher I can go based on those numbers, maybe someone here does

I'm not going to be doing much offroading with it as I have a trail rig already, and this is like my fun commuter rig. I just want it to look awesome, and also get my rpm's down a bit at highway speeds.

Now initially I really wanted to run 285/75/16's but after doing some research that look like too much of a task to contend with when just using the typical smaller lift, and anything 4-6" is ungodly expensive and isn't worth it for me. If I could get 4-6" without spending 2k and doing a ton of fabrication it would be fine, but it looks like I'm going to be dealing with a smaller lift of sorts.

I'm looking to run 265/75/16's on 16x8, 4" backspacing, or maybe some 33x10.5/15's that I found for sale nearby, but I don't want to commit to one over the other until I have some stuff sorted out.

From what I understand I have to be careful how high I lift because of the shorter CV on the CRD getting bound up. But wouldn't the cv get bound up at full droop anyway if that's the case? Regardless, I remember seeing a person who had mounted a limiting strap to prevent that from happening and avoided having to have the cv's cut down, so I figure I can do something like that, too.

I was also wondering, since I don't have a complete grasp on how everything goes around here yet, if I could get away with running the OME lift in combination w/ my current spacers. Or if I just just strip out whats under there and go w/ a Frankenlift or whatever. I'll probably need the A-arms, too, right?

Ultimately I don't want to end up thousands of dollars in the hole with not much to show for it. A 32" tire is the minimum I want to do. But I also don't want to have to hack the rig up just yet. Inner fender Modifications I'm ok with, as well as sacrificing some wheel travel via bumpstops and limiting straps to keep things from getting destroyed, but I'm NOT ready to tear into the outer sheetmetal. Unless there are some cut out flares I haven't seen or heard about...

anyway hope my questions are legible and thanks to whomever answers

Some have managed to run 235-85-16s which is a 32 inch tire, NO BIGGER WILL FIT, so give up the idea of 33s etc.
Limiting straps will not do much good if any at all
Your wheel choice will not work that good, a wheel with 4 inches of back spacing 7 inches wide works good, but not 8 inches wide
No matter if its your trail rig or DD you do want a good ride ? Correct?
So go with either OME 790 springs and OME front shocks or go with the Frankenlift, tried and proven. ( You have to use the OME 790 springs as they will hold the weight of the engine) In the rear OME 948s and OME 132(L) shocks.
Other shocks are available but it seems for the CRD the OMEs work best.

what color are your springs? i know the frankenlift comes with good springs AND spacers it may be you already have a decent lift on it

tommudd, you say some have gotten 235/85 on a CRD, how about 265/75? I can deal with taking sharp turns a little wider to keep the rubbing down if that's all it is.

Also, having a tough time tracking down aftermarket 16x7 aluminum wheels. Plenty of steel, but I'm trying to keep the weight as low as possible. Moab's seem to be the wheel of choice but I'd rather have options.

Keep your stock wheels, they will work
235-85s are more narrow so will fit better. unless you go with an ARB you'll have to do a lot of cutting of the front bumper as well. Also you'll lose power/mileage going to a larger tire like those
taking turns wider due to tire size IS NOT a good idea, whats happens in an emergency situation? You crank the wheel hard right and it catches and BAM!

Hmm... lots to ponder here. I get what you are saying about emergency maneuvers, but wouldn't lose half my steering radius from an extra half inch of tire would I?

Adding maybe another inch of lift and half inch of tire I'd rather compensate by getting a little wider stance from a different offset wheel (I'd feel safer with different wheels than a spacer). I already have 10.5" wide tire on there now. When I get back to the States in a few weeks I'll have a better idea of where it looks like it will rub and go from there.

Regarding power/mileage loss, I'm planning on a tune for the engine and combined with the lower revs at highway speeds I feel like I'd probably not be much worse off than I am now.

Thanks for your help and advice.

The max lift for a CRD is 2.5" which clears the biggest tire the front diff will turn safely. If you're feeling froggy, you can go with the cradle drop and the steel front diff and the 6" lift so you can look cool.

The tire Tom recommended will maximize clearance and performance off-road (and MPG on road). I currenty have a set of 265/75R16 Discoverer STT that I tried out in MOAB and no es bueno. I got them for free and I am afraid I overpaid.

I will put the 235/85/R16 MT/R back on for my next trip in Sept; this is the tire that I've used since 2007 all over the US.

I just switched to 235x85 R16 General Grabber AT2 and gained over an inch in height over the 245x75's I was running. Little bit of rub on the fronts at full lock, just catching the liner. I think it could be easily fixed with 1/2" spacers or different offset wheels. I have the OME lift, with a top plate and an extra rear upper isolater and pinch weld pounded down. I think I picked up almost 2 mpg as well on my weekend 600 mile trip.

I'm looking for 16x7 wheels with 4.75" to 5" backspacing. Only wheel I've found so far are the Icon's from a 2000-01 Cherokee. I think they would be perfect fit. extra 1/2 inch on each side, still within the wheel well.

For the investment in a 6" lift, I might as well go solid axle, but I'll wait til it's paid for before I get too crazy with it.

What size and backspacing wheels were you running the 265/75's on? What were your issues? Just more rubbing?

Have you had your 235/85's in sand? If so, after airing down did you get around ok?

Hey... i know you don't know me but if you did, you'd know I wasn't RECOMMENDING the cradle drop and 6" lift, I was just making sure that you were aware that the option exisits.

I've had my MT/Rs on the highest trails of CO to the seemingly endless deserts of SE Utah to the door-handle deep swamps of FL and with airing down to 15 PSI I've only done slightly worse than "real" Jeeps
