I still have the original, 25 year old donut spare in my Accord. I've never had to use it, but I would if I had to. The things are not made to be driven at high speeds or long distances anyway; they're just meant to get you home or to the nearest repair shop so you're not stranded in the middle of nowhere. If you drive the way you're supposed to when you have a donut wheel on, even if it did fail, you won't have a catastrophe.
