All TPMS sensors are swappable as well once you get a couple rotations on them the computer automatically recognizes them.
Awesome - that's all I wanted to know, thanks!
I asked because I am thinking of the option of getting a Summit with the offroad-package to get all the offroad-stuff factory-installed. However, I prefer the appearance of the 20" wheels over those 18" wheels. That would also give me the option to get some higher grade tires than those OEM ones.
Still a while 'til I'm in the market but it's good to know the options and potential obstacles.
