Personally I would run at least 4.10's if you were staying with 35's and did any wheeling, however if there were a possiblilty of 37's in the future I would definitely lean towards the 4.56's or 4.88's so no future gear changes would be needed.
Speaking for the 2012 and 2013 models only.

Default 35" Hankook tires
I've been having problems with "death wobble". We added a double damp, found a bolt that needed tightening, and had the tires rotated and balanced by a truck tire dealer so they'd have the right equipment. Now I have more of a shimmy than the "wobble" in the steering wheel.
I took it to the dealer, without really looking they said tires. " These tires are for off road (really?) and if I'd just buy new tires it'd go away" (these are new)
Any thoughts or experience with this issue.

There are lots of threads for the death wobble on here and jk forum and jk freaks. Search for those threads. I haven't had this issue but i know that new tires, steering stabilizers etc wonto fix it.

Also search for service bulletins for you jeeps vin!

Good luck

Wow! Never go to that dealer again. You can't blame the tires without taking a look at everything else. Something is loose/worn in the steering or control arms. I'd check that. Could be as simple as one of the tie rod ends being worn. Look at these 2 youtube videos, they'll shed some light:

Great Thread!

I had no idea gas mileage would drop so much with bigger tires!
Im planning to go with a 2.5 lift with 35 inch tires. From the forum, I think I'm leaning towards 4.10 gearing. Where can I buy them? Also, whats a good price for the gears + install?

Thanks for all the help!

I Juat don't know what to believe and i would kill.myself (not literally) if I spent 1200-1500 ish on tires only to be sluggish or wreck my tranny, transfercase or other things
FOr a 2012 with 35's you don't need to go higher than 4:56. I've studied the crap out of this. Trust me.

Do you know anyone near you with an 07-11 that has 35's with 4:88? If so drive it. If you like it then 4:56 will produce the same feel for a 2012 or later.

I do, and even they say that its 3.6L with 35s and 4.88s are sluggish and wish they'd gone with 5.13s!

Yes, you can run 35's. You have 3.6L motor. You don't even need to regear it that low, or regear it at all.
