yes, my 1LT came with the spare doughnut
I also have the trailering package but, it's still a doughnut.
Yes, I did not try it yet but it looks like it's the same concept as my Xterra.... you just lower the tire via a bolt located in the trunk storage compartment. In my X, it's chain that lowers the tire down.
I called the dealership and the guy that answered at the parts department said "well it's a new car so I'm not sure." huh?... the 2010s either are or will be on the lot soon.. come on!
I remember when I bought the car they showed me a list of all their machanics... and their years of experience ranging from 2 - 30 or 40

... you would think that my question was a simple one. I guess I can call again later & ask ... hopefully getting someone else.
