How would you deflate or better yet shrink a space saver spare.I'm talking about the spare that came with the Bertone Coupe.Originally it came uninflated and it would fit in the tire well.The coupe did not have the deep well to fit a full size spare,talk about poor engineering.The spare with this coupe was inflated because the original air compressor went missing.I'm trying to get ideas on how to "squeeze" this thing back to or close to original.I know if I remove the shrader valve all the air will come out but then what?Thanks for any ideas.
