I didn't realize that it requires an unusual volume of "balls" to ask a question such as this
It's not like I asked if I can fit 33's with only a 4" lift
There has been allot of good feedback on this subject
I do agree that a smaller spare is not a good idea though we haven't heard from anyone that has actually tried it!
Turning off the control systems is probably the only way to do this without severe problems.
I understand that our Jeeps came with a spare tire of the same size as the other four though I would not call any of them "Full Sized"
My main reason for starting this topic is a road trip in July.
I have 5 new wheels waiting for tires and a re-gear to 4.88's.
My spare tire was stolen last week otherwise the tires and re-gear would wait until after the trip.
So my options are stock tires no spare, new tires 3.21 gears, new tires 4.88 gears with very little time for brake-in and very little $ left, or the worst option Ride in my buddies mini-van
I do have a ViAir system ready to be installed so that reduces the risk!
Thanks for all of your continued input
