Gobi roof rack with spare

[Racer-X]

You know, all you need to do is put a moving blanket on the roof and let it hang over the rear glass. You should be able to lift the tire up enough to slide it up on the rear edge. Thats how I did it. Too bad that lift wasn't always available though.

I also keep one of those puncture repair kits in the back as a first option.
