"Too Much Stuff"
One thing to consider when using a donut is the fact that it should not be used on the drive axle with a full sized tire on the other side, at least not for very far. It is better to swap tires around; so the donut is opposite a full size tire on a straight axle. About a year ago I had two flats within a two day span that turned out to be due to the valve stems separating. I took the car in to have the remaining two valves to be replaced. It is costly, but having AAA is a big help when problems arise.
