changing tires yourself

Seems to me from regular reading of this forum that Badbob is the only one who changes his own tires on a regular basis (I could be wrong, of course). That makes me think it's something I should not do, but I'll ask anyway as I'm thinking of taking some long trips on the gz250 in some pretty isolated Michigan country.

Even if you could master the technique, what, for instance, is the biggest risk? Breaking some spokes? Bending the rim? Other risks?

Thanks,

Keith
