Put some old cotton gardening gloves in with the spare! When you have to change a tire, the wheel will have nasty brake dust all over the inside no matter how carefully you've cleaned the outside. It's impossible to keep from getting this stuff all over your hands, and from there spreading it to your clothes, the inside of the car, and all the crap you touch while changing your flat. I happened to have a pair with me last month, and it saved a lot of cleaning the day after.
