Mopar Lift/Tire Size Recommendations to Fit Hard Rock JKU Wheels with no Spacers

With the 2" Mopar lift you still need spacers to mount the 315/70/17 Duratracs on stock Rubicon wheels? Trying to avoid spacers, but keep the same factory Rubicon rims with 35" or 33" tires, thoughts? Perhaps 285/70/17 would work better on stock rims with no spacers on the 2" lift? Is the Stage 3 3" Mopar lift even a consideration with stock Rubicon wheels? Best tire/lift size recommendations appreciated. Thanks for reading!

Forget 35s - you will need spacers. I think 34s with 11.0" SW will work without spacers.

Measure twice, cut once..

Just remember that you are dealing with a 3 dimensional issue. There are approximately 4,359,232 Facebook discussions, forum threads, and google hits that will answer this question for you in almost as many different ways. 315, 35, 12.5 wide...WHATEVER way you look at it, on stock wheels they'll rub under the Jeep if you turn the steering wheel or flex. A 2-4" lift will move the flares and body UP, but you've still added about 2 1/2" of tire width and overall volume due to increased tire height.

Quit stressing about it and drive your Jeep for a while, then decide what you want to do. You want wider tires? Then get new wheels or use spacers.

Re: Mopar Lift/Tire Size Recommendations to Fit Hard Rock JKU Wheels with no Spacers

Thank you! That's the best advice and that's actually what I've been doing. I already switched out with a generous trade in of our stock KMs to same size 255/75/17 Duratracs, with forum advice I lowered the psi to within a 37-40 range and already I'm feeling the improved performance and comfort both on and off the beaten path. I've enjoyed seeing those 285 versions of this tire with stock Rubi wheels, and friends checking out our new Jeep keep asking when we're going to fatten up our toy truck lol. The tire vendors like to ignite the fear in spacer installations, but we owners know what fun we're in store for. I'm actually stressing more now between 1.25 and 1.5 Spidertax just to get the right look without too much tread showing beyond the stock fenders. But as you've so eloquently expressed there's no rush. Even with 285's I can stall the lift for now. I know I should be happy with what I have, but as many here I'm sure will attest, this Wrangler updating can sure be addictive and in its own way a fun destressor from the real world. I already made one mistake.

I trusted a great recommendation here for purchasing the well reviewed AEV rear backup system, but without noticing any disclaimer by the factory, the vendor seemed to feel that the stock Rubi Tirerack would fit the camera just right, when in actuality without purchasing the matching AEV tire rack, the camera is set too far into the Rubi wheel well resulting in a reduced visability scalloped display appearing at the bottom of our 430n factory screen. So am now in the process of removing this new camera system and hopefully will find a buyer here in the forum, as it is a great product just not meant for our stock tire rack and rims. Pac-Audio has a newly introduced rear camera display system with wide angle and full screen viewing I'm presently looking into. Will let everyone know how I make out with this new camera.

Happy Turkey Day!!
