largest tires for stock?

Can a Rubi run 33's without issues?

Also, anyone take thier stock Rubi on the Rubicon and live to tell about it? I'm thinking of going with some buddies and KNOW I will not have it lifted by then.

Stock 4-door with a 6-spd on the Rubicon. Ouch. 33's only give you another 1/2-inch of clearance.

Can it be done? Yes. Can it be done without undercarriage abuse? Not likely. Your longer wheelbase will make it a pretty grueling trip, with plenty of opportunities for your buddies to drag you off of stuff. And I wouldn't count on keeping the stock bumpers intact. JMO.

Sure you can run the 33's.

Thanks for the input. I realize the potential for damage and also know a lift will go a long way. Right now I am trying to balance the passion for the outdors with the grocery bill

That'll work for my 3 teenagers. Turns out my wife and I are the choosey ones. I like stouts and black ales with my tri-tip.

Inexpensive mods are the order of the day... I'll be welding on some protection. Looking for a good oil pan/exhaust/tranny skid plate. I'll paint it myself. And thinking of picking up some used OS tires (33-35?) on beater rims to swap out for trail runs. I know 35's won't clear. What if I cut away some of my flenders? They'll have to be replaced someday anyway...

A BB wouldn't set you back much, and would allow 35s to clear. You could also just run it like it is and fix what breaks (or breaks off). That may or may not be cheaper.

I followed and wheeled (and saved) with the engineers through the Rubicon right before the JK release. Watching the engineers "drive them like they stole em" is really what led me to buy a JK. The skids on all of the mules were upgraded, at least the ones that ran the whole trail, not just down Cadillac and back like the ones that were there for the media. With the skids, the only real damage was the bumpers and an occasional lost fender. They also did NOT air down and very seldomly did anyone need a tug. With front and rear lockers, traction didn't seem to be much of an issue and the added height from the aired up tires seemed like a better trade off.

IF I were to run it without a lift...I would skid the bottom, pull the plastic bumpers and the fenders( if you don't they will get ripped off). Then you could run bigger tires and you should make it through ok if you take the easy lines.

2007 stock RUBICON ON 32'S
Before they closed the by pass to ellis creek My daughter drove and I and a friend guided.
We went from ellis creek down to Wentworth Springs, about 1 1/2 miles. WE went very slow picking the lines very carfully. The only damage was a dented oil Pan.
I wish you luck.

Yeah! Thanks for the pointers. I really appreciate the input.
I have argued the point of not airing down on the tough bouldered trails. My buddy says you HAVE to, but he's running 35x16's, plenty o' sidewall.

My current plan is to add a oil/tranny skid, cut the flenders to be just flares and maybe get some used 33's (35's if they'll fit, but I doubt it) on 16" wheels.

But aren't most BB just spacers in the springs, limiting your ability to get good traction? I always thought it was better to leave it loose and low than tight and high. I could be wrong.

Don't air down if you are running stock.....I ran the Ladder at Slick Rock which is a granite face and I walked right up it stock without touching the valve stems. My TJ with 35" MT/Rs aired down to 7lbs, had a harder time on that section then the JK (added wheelbase). Like I said, I watched the Jeep people run 25 JKs on the Rubicon and they didn't air down.

I would guess if you totally removed the fenders, trim a bit, and ran some 2 inch wheel spacers you could get some 35's under that thing. IF the lower40 could do it with raised fenders, you could do 35's with none.

a b/b has little to do with traction. for a simple low lift that has a minimal impact on the ride and handling, a b/b is the way to go. all you are really "limiting" yourself to is the factory coils. with some carefull measuring, you can fit a long travel shock on it, extended brake lines, appropriate swaybar discos or links... and the suspension will flex nicely. i currently have 12" travel shocks on the front and Poly Perf rear shock brackets.... havent had the money to get the new rear shocks yet.. or the brake lines.

i have run a b/b on a 98 ZJ (later with lift coils, b/b and LAs) and on this JK with no trouble in handling, traction or performance in general.

If you plan on running a stock front bumper, I'd recommend the Skid Row front skid plate to help you drag your nose a bit instead of bashing on rocks.
Also, a front diff cover would be a wise choice- Mark W.
Edit- as for the OP, 285/70/17's will fit, BUT, you'll want wheel spacers on OEM wheels, or you'll rub at full lock. Also, at full stuff, you MAY rub depending on the tire- Mark W.

I have a nice set of stock bumpers you can have, but I live 4 miles from Mickey and that is a long drive from Livermore. On the other hand you can pick up a TeraFlex 2.5" BB lift for under $300. Even with the Stock 32's that is still more lift. I got mine for $226.00. The Wife and I installed it in our driveway on a Saturday. We ran Cleghorn the next day to test it out. It's been that way for about 1-1/2 years now with no problems. I'm guessing that is less then you would pay for the 33 Inch tires.

Pick up the lift kit, come down to Fullerton for the weekend. I'll help you install it. You can take my stock bumpers back with you as spares.

That there is one nice offer. Don't see that kind of neighborly kindness much these days. Thanks very much and I 'll let you know. I didn't really consider a bb maybe because of the way my brothers and I did them... I'll look further. $226 isn't much, but a good set of skids is proving to be quite a bit more.
I've been thinking I might be able to make some of my own. I have not measured much, and the arms look to be a challenge. But I wonder if I can just weld some blocks on some plate so the bolts are recessed and bolt it on a few places..? I'll have to measure.

I have already cut the corners off the stock soda bottles. I was looking earlier to replace them, but then thought, Nah. I'll just end up crushing them again. I need to save up for a good set of stubbies. Thanks

I see online there's 3 choices - Basic.. With shock adaptors.. With new shocks.
Did you get longer shocks? Stick with the OEM's? Any potential issues with basic setup and OEM shocks (other than shocks too short). What about cuttting the rear shock mounts and moving those up a bit. They should be replaced with the Poly Perf adjustable shock mounts anyway. Tell me what you think about the TF bb !!

I still have my factory shocks with extensions on them. I have wheeled a lot this way and no shock problems yet. When the shocks wear out I'll get longer shocks. My total cost for the lift was $226.00 for the lift kit and I think about $17.52 in tax. 4WP drop shipped to my door at no charge. I got the lift at 4 Wheel parts (On-line) in early 2008.

buy the 2.5 teraflex BB with shock extenders. Find some used 35's and wheels. You will be able to wheel some really good trails with that setup and depending on the wheels and tires, you could probably come out well under $1000.00 I wheeled mine with that setup for 1.5 years and everyone was amazed at how well I went. If you were closer, I would give my 2.5 bb that i just replaced with an rk 3.5. The only downside i ever had was when i added smittybilt front bumper and winch. It dropped the front a full inch. for $115 I put on 4" springs and my steering went to hell on the road. Still did great offroad. I am still running the 2.5 bb on my wifes unlimited with stock 32s and even that is a huge difference. just my 2 cents

Yes I have steel bumpers front and rear. The stock springs do loose some hight with or with out the lift!
