No lift. Larger tires?

I have been searching and reading for a while. I can't find any specific info, or anyone who has done this.

If I get flat flares and short bumpers. What size tires can I run with no lift? Assuming of course my goal is no rubbing, even on the trail in extreme conditions.

Sorry for the noobish question. I just don't really want to lift it, but larger tires, and other mods won't really bother me too much.

why no lift? with even a short lift, say 2.5 inches you can fit a 35 inch tire without having to extend break lines or anything major.....not sure about the setup you're thinking of tho...goodluck!

trim your fenders up a good bit and you could probably run some 33s with out much of an issue

I'm thinking no lift because it is a daily driver, I want to keep my warranty intact, and just avoid any potential issues. I'm still learning, but it seems like there is at least some chance of having issues once you lift.

Also it seems like if you can run larger tires, without lifting the center of gravity, it would be better off road as well as on?

I was thinking about a 2" lift as a possibility. I was thinking more along the lines of the Old Man Emu 2" lift kit. Not sure what I'm doing yet.

Yeah I was thinking flat fenders would get me 33's.

putting on taller tires is still gona raise you COG. just not as much as tires and a lift would. 33s seem like a good bet, any taller and it seems like you have to get into other stuff as well. also think about what gears you have. 33s on 3.23 would probably be a bit of a dog driving on the street.

I was thinking of doing the same. Going to 33 on stock rubicon. Any suggestions on how to do that without any wheel rub? What width tires would i need.

Good point. But 35's on no lift = 1.5" net lift. 35's on a 4" lift = 5.5" net left. 35's might be a pipe dream with no lift, but the point is, less lift = lower CG.

Mike's right about about the COG. Hence even I'm looking for slightly bigger tires only..

OME is good but went with BDS,they were more common locally and they are a good product.If you have 33's on stock height it would work on the road but i just dont see that happening if you go wheeling.Correct backspacing is definitely needed or else you'll rub (sway bar) at full lock IF you go with 12.5 wide tires or you can get wheel spacer if you plan on keeping stock wheels.

Now if you plan on wheelin hard like rock crawling 2" will get you places but make sure you have protection underneath for you will be rubbing your belly depending on the trail rating.Ive done as much as 4 with my set up and i wish i have more clearance.

I did add flat fenders on mine to make room for 35's but still waiting to wear out my 33" MTZ.

Jeeps are like Democrats, every one is different and has different goals/purposes--here's mine

Lots and lots of mods, but just for the thread subject "largest tires"

"08 JK 4dr Rubi (3.8l/4:11 gears/auto)

Bushwacker "pocket" flares (or mod stocks)

RC 2.5" lift (spacers-steel)

Bumpstop extenders

RC9000XL adj shocks, for 2-3" lift

Spidertrax 1.5" adapters

Olympic "rockcrusher" bumpers (clears tires)

Now with the above, I can drive easy on the hiwy at 75 mph and tow trailer

Go off road, in sand/rocks/snow easy, no bumps/rubs/balks

Mike Honcho, I'm running Goodyear Dura Trac 285/70R 17 (32.8").They are a quite running,aggresive looking tire.My JK Wrangler (2010) has 3.21 gears and a 6 speed manual.I'm regearing to 4.56 so I can use ALL 6 gears.

Are you having any wheel rub.. Duratrack are what I'm looking into myself as my rig is a dd and need something for snow up here in Mi during winters..

^He must be. Anything wider than 265 WILL rub at full lock with stock wheels and no spacers. To run any wider than 265, you need either new wheels with less backspacing, or wheel spacers to push the OEM wheels out. My money is always on new wheels over spacers for the usual reasons, although I have run spacers before with zero problems- Mark W.

If you don't want any rubbing just go with a 32" tire. 33's hit just a little bit without the lift. 32's require no mods. However, flat fenders seem to be a trend, at least where I live. I see more and more liftless jeeps running 33"-35" tires with no lift, just by adding some flat fenders. Most extreme I've seen so far was a TJ on what I think were 35's, maybe a mild lift, with flat fenders. Lots of options are out there for you

I have 18" rims from a 2008 JK which replaced the stock 17" rims that came on my Rubicon and have 275 70 18 Wrangler Territory tires with only a very very mild rub at full wheel lock. They look awesome and no lift required.

With no lift, flat or no fenders, and proper BS, you can get anywhere from 38"-40" tires on an unlifted JK.

They look funny though. To make it look right IMO, you need at least a BB for 35" and up. There's a Mopar jeep around somewhere with I believe 2.5" lift and 38's.

For a DD though I'd say no lift with 33's. Why lift if it doesn't leave pavement? Waste of money. If it does go off-road, 2.5" lift with 33's or 35's. Keep in mind your MPG is going to suck even harder, and moving to 35's, and even mild lifts on JK's, MIGHT require additional axle and/or suspension mods.

You can go as big as 35" tires. I would like to do this my self. I hate living with a lifetd Wrangler again. But remember to get the right flat fender kit that you don't have to cut any thing. I think smittybilt offers something but, it isn't cheap. Good Luck

I'm only running a 2" spacer in front and BFG 285/70/17's KM2'S on rims with 4" backspacing. Gives me roughly 32+ in's .

No rubbing, no problems. Lots of off road time!
