Just make sure to post pics when their on
Haha fair enough. So overall: 3.21 + 285 33" duratracs + 2.5 lift + 2dr auto 3.6 engine = I'll be good to go with minimal performance issues, correct?

We have a 2013 JKU and at the 1000 mile mark replaced the factory 17" wheels and tires for 15" rims and 33" Duratracs which are about 32" tall when mounted and pressured to 25 PSI. The only thing we noticed was a better ride and handling although this now includes a 2.5" TF spring kit and Rancho 9000s. Power wise the 5 SP Auto driven by the 3.6 does a great job on or off road and I have towed a 1700 LB trailer about 350 Miles to the hill country several times. Granted when towing I do not go above 65 MPH by choice not because it wont. I have passed people with the trailer and went well above 75 MPH to do it. We also have had 0 issues with wobble or bump steer. Very very pleased with the 33s.

I will say when tires are due to be replaced next year I suppose, we will be going to 35" tires, and 456 gears front and back. Not sure we really need the 35s its just one of those things we may do and of course they do look good.

I am running a 2.5" TF spring lift with the Rancho 9000s for articulation on the trail.No rub and it looks good. Ran the 33s before getting the lift and did not have any rub on the road but did have some when flexed out.

Auto, 3.21, and 33" - Will I regret it?

I have a 2014 JKU with 3.21gears Automatic with 7x9 4.5" backspace BMF Novakane death metal Blake wheels with 315/70/r17 GY Durotracs and AEV procal set to the tire diameter and the jeep drives the same as with the stock 255/75/17 tires.
Shifts just the same.
I use the jeep for a daily driver and I researched before buying the larger tires.
I am glad I didn't listen to the people . That did not have the new 3.6 liter pentastar engine . I feel the motor has ample power and the 3.21 auto tran shifts just as good. I had to lower the tire pressure from original 40psi to 32 psi for better ride. The tires do stick out about 1.5" beyond the stock fenders.
If needed I can get some 2.0" Pacer fender extensions to cover the tires jc Whitney has it. Hope this will help someone else that is researching this.
Happy Jeeping

I have 3.21 with 1.5" leveling lift, 285/70R17 durtrac's on 17x9 rockstar rims and I have been perfectly happy with it both on and off road.
If I had it to do over I would have bought one with 3.73 gearing but I can't imagine wasting the money to re-gear what I already have.
And Welcome to the forum Relish

Not to be "that guy" but it sounds like the changes are entirely for cosmetic reasons. Your concerns are about how much worse it will perform.

I think the Jeep you have, with the wheels you have at the height you already have it at sitting in the driveway of your own, newly purchased home would make you the happiest.
