If I was riding your bike and really getting out there and riding solo, I'd probably find the lightest tire I could run and lash it to my seatbag, though.
vik makes a very valid point about a spare tire being dead weight and mostly useless. I suppose that I could damage a tire enough to make it unusable but I've only ever had one tire damaged in roughly 10,000 miles of loaded touring including about 1000 miles of mountain bike touring. I can't say that I've even damaged a tire enough to be unridable in 40 years of riding and that includes a whole lot more mountain biking. I carry spare tubes, a patch kit and a large piece of Tyvek but I haven't ever needed the Tyvek.
On a side note to vik, if you are worried about weight why are you carrying around a battery powered flasher?
