That's a great, practical question - what to do with the flat. I'm thinking since it's an emergency, that the solution doesn't have to be pretty. Do you think the deflated wheel/tire would fit in the open hatch with the hatch door roped down? If that would work, as inelegant as it may be, it would be preferable to being stuck. What do ya'll think? I don't want to have to deflate and try to stuff a wheel/tire just to find out. Thanks.
