A full-sized spare wheel

If you ever got into a situation where you needed to change a tire, the chances were big that it was a short standing without major delays. Have you tried it on a new car? Slim and pathetic “space saver” restricts you to drive slower, but it is still a better response than spray for filling a punctured tire. (Good luck with that!)

Older cars do not suffer from similar problems, because the “attempt of the wheel” was not yet in use. The good old foot pump, and set for tire replacement, plus the wheel with the spare tire, which is always ready in the trunk, simplified the whole process.
