Space Saver Spare Audi

[SH20]

There have been a lot of comments about space savers or lack of them but Audi have developed a space saver for their large SUV type hybrid cars which has a conventional space saver steel wheel rim with a collapsible tyre.   It inflates like a conventional tyre and expands to twice it's size so the tyre wall depth doubles in height and when you have used it you let the air out and the tyre shrinks back to the original size which then fits back under the dummy floor.    A full size space saver for this Audi would not fit under the dummy floor but the shrinkable tyre makes it possible to have one.    The video is on YouTube
