Do the 2008 KK wheels have the same 5 on 4 1/2 bolt pattern as the KJ's?

Anyone know the backspacing on the '08 wheels?

Will the tire pressure sensors from any year KJ or KK wheel work on a 2007 KJ?

The reason I ask is I'm pretty well set on using two sets of tires for my KJ. One set will be for road trips and summertime. During the winter, when we do our off-roading around these parts, I'd like to run a second, more agressive set of tires, probably the new BFG KM2 (245/70/17). I'd like to find a second set of factory wheels for the second set. The new KK has some nice looking 16 and 17 inch rims.
