New Rubicon

Does anyone know the rationale for the Rubicon having smaller tires than the Sahara? I thought big tires were the end all, be all for off road?

Rubi is 32(more like 31.5) rim size its better to have less rim MORE tire.

They are nominally the same size. If they are larger it is because the wheel itself is larger and you need some sidewall to protect the wheels and provide a reasonable ride.

the Rubicon has 32" mud tires (BFG KM) on a 17" wheel. The Sahara has street tires on an 18" wheel. It's not the size it is the type of tire.

A 30" MTR/K will out preform a 32" highway terrain any day off road.

Rubicon has smaller tires than the Sahara? News to me. The Sahara has 18" wheels, while the Rubicon has smaller 17" wheels. I thought the tires were pretty close to the same diameter though?

I think the Sahara comes with 265 width and the Rubicon with 255s. Very similar diameter, and the MTs are obviously better off road

Mathematically, they are the same outer diameter.

Size
255/75-17 (Rubicon)
255/70-18 (Sahara)

Sidewall
7.5"
7.0"

Radius
16.0"
16.0"

Diameter
32.1"
32.1"

Circumference
100.7"
100.7"

Revolutions / Mile
629
629

They're close enough that you wouldn't need to reprogram your speedo for accuracy if switching between the two (putting Rubi take-offs on a Sahara).

Only thing to remember is that not all tires are the same, and two different tire models the same size could / do measure differently.

Another Uconnect Question

Everytime I sell a Wrangler I miss it. The wife approves and I should be picking up a 2014 this week.

As it sits right now I will be getting the NAV radio but not the connectivity package. I could care less about the info center but I do want to be able to make calls and hook up the iphone for music.

Does anyone have experience with the kit to do this? It looks like an easy install, but does the dealer need to get involved?

Get the Connectivity Group and forgo the navigation system. The navigation units Chrysler puts in Jeeps are antiquated garbage. The Connectivity Group is what gives you the UConnect features you're looking for. You can easily plug your iPod into the radio (via the inside of the center console) or stream BT audio such as Pandora and you'll save a good $500, if not more. Need a nav? Use your phone. It'll be 10x better, more accurate, and less expensive in the long run anyway.

I came to the same conclusion after researching the available options.
