Try this link below for the instruction manual pdf. The parts list on the front page illustrates a wheel with no tire but all the photos in the sheet show the complete temp spare (both tire and wheel) so I'm sure the illustration is wrong. Otherwise it shows you everything that is included in the kit.
I think I will end up buying the kit when my roadster is delivered as long as the spare and tools fit completely in the well and I don't lose any trunk space.
