I totally agree. This is why I had to get the spare wheel. Regarding the wheel wrench, the one that came with the jazz worked fine so can confirm that no extra tools are necessary.
depends who tightened the nuts last, and how long ago. I always carry a telescopic wrench, opens out from 300 to 600mm long, use short length to tighten and long length to remove nuts - don't cost much and come with reversible 17 and 19mm full hexagon socket (picture attached).
no good having a spare wheel if you can't get the old one off, I broke an OEM wrench once trying to get nuts off that had been put on by a bloke with tattoos and an air wrench at tyre fitters.
