255/80/r17 is a true 33" Pizza Cutter Tire that will fit a stock JK with no further mods required. Plenty of clearance inside the wheel well with no rubbing. BFG Mud Terrain KM2 is what I have been running for 60K. You're Welcome.
I'm running no lift, 17x8 wheels with -6 offset and 4.75 backspacing with 33"x12.5" tires and have zero rub. Jeep looks great man, although please get the matching spare tire one day :)
Geat video man. Seriously ive been look for weeks on a video that actually talks about stock height and the DAMN WHEEL SIZE . They always talk about the tire yadyada but never the wheel size. Thank you!
I have been searching for days (like, not dedicated 8 hours a day but here and there the last few days) trying to figure out what I can run on my 2013 Wrangler JK Unlimited. I will be going offroad but more through mud, over volcanic rock, and old coral. I will be hitting big potholes but no extreme offroading like in Canada or the State. Anywhoo, it's been a nightmare trying to figure out what I need. This video helped a lot. I think you need to start calling your videos Jeeps for dummies or something because you broke it down so I could understand it. Thanks :) I'm going to try a 16" wheel 32/12.5R16 or 318/64R16
There's only 7/10 of an inch difference in overall diameter between the 255/70/18 (32.1" diameter) tire that came on that Jeep and the 285/70/17 (32.8" diameter) tire that you put on the Jeep. Only half off that difference is to be considered in terms of clearance. That means there's only 3.5/10 of an inch (just over a 1/3") difference from the stock tire and the new tire in terms of clearance. When you add the negative offset from the new wheel's backspacing then you should have pretty much the exact same clearance as when the Jeep was stock.
I just upgraded my non-lifted JK to 285/75R16 BFG KO2 and mine rub the sway bar on full turn, so I'll be adding some spacers soon. I also had to reprogram my speedometer to adjust for the change, and notice more play in my steering wheel than before. I'm running 3.73 gears, but will also likely upgrade those in the future because it's definitely not as punchy as it used to be, and my brakes feel softer with the larger and heavier tires.
If you get at least a 0 offset there would be no need to run spacers! Make sure you get the correct width and offset rim the next go around. I hate spacers so much. Lol. My speedo was off by about 4 MPH on average. I never adjusted it. You'll get more or less play in the wheel depending on your tire pressure, especially with a taller sidewall.
Interesting, while I do want 33s and a JL Jeep because they are perfect not too big, not too small, it 35s do look a little better but I still value my traction and grip when turning. I’m not sure if I want a lift since I’m 5’4 and the first one I ever test drove, it had 35s, a big lift and it was a 4 door rubicon, and for me it was a little too much since I’m not used to the height, since I drive a fort escape for now, and the steering wheels was so loose it was scary. Another Jeep owner said it might have just been that one when it came to the steering wheel and she had a 2 door jk. She says her’s turns on a dime which I love but I want a 4 door. And I didn’t even think about rubbing when it came to tire size, I was more worried about the grip/traction, and somewhat how will parking go, since I forgot that the bumper and the spare tire are first things to hit something if I’m parking somewhere or almost run into someone, so that will be something to get used too but the escape was the perfect test dummy since they are both the same width.
Great video and explanation! Debating going the same route with my 2008 JKU Sahara. Bone stock, but looking at some JL Rubi Take Offs with 33 KO2s on them. I feel like this will be my gateway drug into a leveling kit (which WILL limit my up travel) and then a more conventional lift shortly after. ;)
I did this exact thing. Got a little rub on the drivers side swaybar at full lock but I'm going to get a set of spidertrax spacers to solve it. I'm gonna level eventually too
I just tried doing 285/70/17 tires on stock JK Sport S wheels not very fun. Way too much rub especially when doing full 90 degree turns. I got some new American racing Baja wheels and it fixed all the rub issues
Wait a minute guys, the tire may fit but without a lift kit that jeep can't do much without ripping the body up. He would have done better leaving the original tires on because they allowed more body clearance when bouncing one the shocks. You have to lift it for those tires, I just did the Mopar 2.5 inch lift with 33's. 2014 JK
good video. Thanks. The 33s are surprisingly close in size to the stock wheels. Are the new wheels measured in metric or imperial? I'm in Canada and have a hard time figuring it out. They look like 285/70/17 I'm I correct?

Your recommendation to not get those tires on stock wheels is inaccurate. The stock wheels actually rub less than what you have there because you changed your offset. If you have a Rubicon/Willys and have removed the air dam, there is NO rubbing with 285/70/17’s. Sports and Saharas can get NO rubbing on stock wheels if you add a washer to the steering stop bolts.
Thanks for that information. I have been debating between 285/70/17's and 285/75/17's. What are your thoughts on running 285/75/17's? Will I need spacers? Will I need a lift kit or can I get away with a leveling kit? Ultimately, I plan on adding a TeraFlex 2.5 lift but that is a little further down the road.
kourgath007 I don’t think you can fit the 285/75 tires on there without a lift, and if you could it would probably look kinda silly. I like the look of the 285/70’s on stock setup or with a leveling kit. Once I’m ready for a lift I’m leaning towards the Mopar 2.5” which is supposedly closer to 3” up front, then just go with the 315/70/17 (35” equivalent) tires.
yes, adding wheel spacers or different than stock backspaced wheels actually does make it worse since they you will contract the lip of the fender due to the WIDTH. so NO spacer and no changre in stock backspace, and maybe a 1/8" washer and you are fine on paved roads. But you will rub like hell off road. essentially if you disconnect front sway you are toast off road on 285/70r17 unless you do a 2" lift
Was this video helpful to you? Give it a like! If you have any questions about my setup just ask in the comments. Going to do a simple leveling kit soon.
I'm getting the impression this is probably a bad idea if you push it pretty hard offroad. I think I'm going to just wait until I can lift it and get clearance the right way.
Really good video man !! question I have a set of wheels and tires from a Jeep rubicon 2020 and comes with sensors, tires are size 285/70/17 I’m trying to put it on my Jeep rubicon Unlimite 2017 You think sensors will work with my Jeep And do I need to lift it my Jeep Please let me know Thanks.
Hi Brother, I just installed 275/70/r18 on my rubicon recon. I needed new tires and they didnt have the size that I was using before , 265, so I went with this size, which is effectively a 33 i believe. It rubs, but besides from that, it all seems well. I have no idea what I just did lol, am I good to go? Ive been driving for like 2 days already....I dont do any hardcore offroad, just 4Low applications from time to time...but here in Costa Rica sway bar disconnection is very very rare even for hardcore offroaders....
it's more than likely just rubbing on that front lower water guard. That is plastic so just see where it is rubbing and cut a small section off. Usually the lower outside corner. Tire can hit it when turning and articulated.
how is it after u put the leveling kit on it? i already have a leveling kit on mine but was thinking about putting 33's on and hoping to get some lift out of them...do the 33's affect mpg much?
I have the stock 18 inch rims on my Jeep, want to go to the KO2 tires. The stock size is 255/70/R18 which KO2 comes in, but it’s a 8 ply tire not 10 ply from what I read. So was thinking about doing 265/70/R18 instead that does come in 10 ply. I’m guessing I shouldn’t get any rubbing going from 255 to 265
@@jasondevereaux3369 as long as you have the proper backspacing. Mine is 4.75 backspacing and you might only rub the front splash shield a tiny bit under extreme turning and angle.
Stock wheels rub less than these shown in the video, or not at all depending on if you have a Rubicon/Willys. On a Sport/Sahara most guys just add a washer to the steering stop bolt and have NO rubbing at all. IMO changing your offset is only a good idea if you jump up to 35’s.
JL's Jk I do and wheel harder than most... I came from TJs, a stock JK is equivalent to my modified TJ. A rubicon has all the mods I need for Colorado’s toughest trails (for the most part). Might go to 33s tho to be on the same playing field as the JL.
Are you running stock shocks too? I have the same setup and I don’t like how bumpy it is. It’s a daily any bumps in the road I can feel them. What’s you psi?
exactly, and exacerbating width issue with spacers which really bring the tire even further out under the fender lip which costs 2" right there compared to being in the fender cavity. put 1.5 of backspace with new wheels or spacers, and thetrire width also putting you further out and you will be smashing tire into fender lip on any novice trail
You need to buy a tripod. You have the shakes and it is really annoying. It is probably the reason you can't keep the camera focused. I can't watch it.
