Why only 33" tires on the Wrangler Rubicon 392?

Why would you want to spend more for junk factory wheels and tires? First thing almost everyone gets rid of,

35s would also make a JL handle like sh*t. Going from 33 to 35 would add at least 20 lbs of unstrung weight to each corner. That is significant.

One thing is to buy a new JL with 33” tires, go to Discount Tire, and after spending $2,500 on new 35s and wheels, be in denial about the fact that it handles like a tractor. Another, entirely, is to test drive a brand-new JL with 35s and realize then and there, before buying it, that it handles like tractor.

Also, 35s might have resulted in a Monroney showing an estimated EPA MPG of 13/18...making it a pill even more bitter to swallow.

Add to that a $70,000 MSRP, and the rest of the “Jeep experience”: dealer markups, crummy salespeople, etc., etc., and one could see why FCA wouldn’t want to take so many chances upfront.

Dude, just go buy a Kia already. Your disdain for Jeep is getting old.

destroyed axles being claimed under warranty

these are the reasons. If you’re thinking about romping on 37+ “ tires you better be budgeting for a D60 swap

OP, you're not alone in being puzzled by the 33's. It just feels unfinished and incomplete. 35's would have been a nice compromise. Sure, tires are easy to swap...but the warranty concerns on such an expensive, and powerful, rig would give me pause to do so.

If you went with 315 KO2s, you'd have actually a 34.5 inch tire that doesn't weigh much more than the 285s. Some 285s, like the Fakens, might weigh as much or more than the 315 KO2s, which are at about 64lbs. So on stock wheels, it wouldn't be a huge difference. I'm a little surprised they didn't go for that.

I think the photos look off with 33's. 2" lift is too much on 33s. What is the stock JLUR lift? 1"?

In the Intro video, play starting at 14:18. It clearly says Jeep Performance parts will have options for bigger wheels and tires and upgraded axles. I'm not sure how big of tire they will warranty with the stock axles, but I think they expect people will be going bigger than 33's. It may be like some other things, where if they sell you the parts, the warranty stays intact.

It would have been fine, but there would be more stress on the drivetrain, which will be pretty maxed out with the power coming from that V8 through the 33's, as is.
I wasn't worried about anything holding up. There would be less stress on the drivetrain with the 4.10 due to it being a lower ratio. I was asking how much quicker the 0-60 times would be with the 4.10s would be over the 3.73s.

35s will be an option
i had heard not until next (MY) year, along with the model refresh. But they will be offered.

if none of the other components change, it would seem hard for them to deny a warranty claim if you did the swap yourself, but they could
