No, I mean biggest wheel you can fit without getting wheel spacers or offset wheels to prevent sidewall rub on full turns.
Ok cool, thanks. I'm trying to decide between 275/70R18 and 285/65R18 on stock Sahara wheels and no lift. I've read 285/70/18 might work as well but I haven't seen any pics of that yet. Seen pics of the first two sizes on stock Sahara.

I have 275/70R18 but I have Rubicon suspension swap. So no, completely stock wouldn’t work.

If I recall from doing this research, 275/70/18 will give you a lot larger tire selection than anything larger. Not saying there aren't larger but the selection starts to get limited.

There are a few 275/70/18 Saharas running around with stock suspension and it does in fact work - I want to say I saw someone go 295/70/18 but I probably wouldn't go any bigger than what you did on stock suspension.

FWIW, I'm stock and will likely go 275/70/18 when the time comes.

At the tire place right now getting my new wheels and tires mounted. Went with black rhino barstows with 315/70/17, only mods are rubicon fender flares. We'll see how it goes....

if you stick with stock suspension you can always swap to rubi fenders for more clearance.

That looks outstanding. I have been eyeing those wheels. Are they the 17x8 30 offset or the 17x9.5 -18 offset? Do you have a shot down the side to show how far the tires stick out?

These are the 17x9.5 -18 offset, Ill take a picture down the side. They do stick out but it isn't as bad as I expected. I much rather would have -12 offset or so to get them to tuck better.

Do you have any issues with the spare tire rubbing on the stock bumper?
Actually I didn’t change the spare tire. I just purchased a rigid spare tire cover and put that on instead which I think looks pretty decent. Btw I just ordered 285/75R18 Duratracs today and will get them installed in a few days.

I just put 285/65/18 BFG KO2’s E load on 18x9 ATX Lege Rims. The tires are considerably more aggressive looking than stock and no rubbing issues at all. I cannot tell the difference in ride quality so no downside there. Here’s a few pics for your research. Good luck!
This looks really good. No lift correct? Did you have to recalculate speedo? Does it look like you could you have went any bigger in tire size with no rub? THANKS MUCH

Installed 275/70R18 BFG K02's on my 2018 JLUS's stock 18"x7.5" rims. No rub, no spacing, no lift. Fit great. Anything in 18" rims is forced into load type E as a LT tire is required (Lite Truck) but the K02's don't feel much different from the stock duelers and they look awesome. No difference in noise, bit bouncier ride which is fine. Only issue is the speedometer is slightly off and could be recalibrated but dealers are saying that's like $300 so we'll see on that one. I've attached a chart to show the speedometer difference when upgrading to this size tire from stock. Thanks to everyone in this thread helping a newb out! Your input has been much appreciated.

Rubbing on the inside of the wheel well ? Really want to do a 305/70/18 on the stock wheel it is slightly taller and wider.
