Spare Tire Question
Can you use a stock rubicon tire as a spare if you have 33's or even 35's?
The reason I ask is I have 2 brand new rubi tires and am getting 33's or 35's so I thought maybe I could save $300 by using one of them as the spare. Plus I wouldnt have to get a tire carrier.
This would only be used at lower speeds and as an emergency, get me outta trouble type of deal.
Or am I just stupid?

You really don't want to run a stock tire as a spare when you have over sized tires on your rig especially when you have lockers. a large on one side and a small tire on the other side of an axle will make your differential work overtime do to the small tire spinning at a faster rate than the large tire.
If you loose a tire on the trail and need your locker to get you out you can pretty much assume your going to break something with 2 different sized tires locked together.
I hope I have made sense.
There is no such thing as a dumb question.
Good luck!

I have a question. What causes the break in the transfer case I have seen on the project-jk videos?
Not trying to jack the thread, just curious.

Vibrations that harmonize without absorbsion is udually the case (No Punn). Things like shaft balance , shaft speed from regearing , improper pinion angle from lift installs.
Harmonic dampeners used to be commonplace on transfer cases (Usually heavy rubber discs with a heavy rubber plate fastened to them) that absorbed harmonic vibrations. With new oem aplications getting very close tolerances from the factory reducing vibrations they started to not have the need for them.
However, once outside the factory specs (Hence regear , lift and pinion angles) introduction of vibrations is a very easy thing to incur as the factory spec is now no longer in play.

Meh yes that too. If you are spinning free in the front pretty good as you are cresting a rock and go from spinning to traction and rear goes free (Like seesaw action) then yes expect a shattered case. OR if stuck THEN shifting into 4wd and wheelspin is allowed before engagement actually happens that will do it too.
