Many new cars have “run-flats,” which can be used even if they get a puncture/go flat.
However, they are more expensive, they don’t function under certain kinds of flats (e.g., sidewall damage), they have limited range, and limited speed.
The tiny “donut” spares on some cars are also not intended for high speeds, but I’d much prefer that to a punctured run-flat. (You should probably place the donut on the rear of your car is front wheel drive, though.)

I read somewhere that you should always replace a back wheel with a donut spare, even if that means swapping a punctured front wheel with an original back wheel.
The donut spares are so flimsy that they can’t be trusted to reliably handle the side loads a front wheel experiences when your car is turning.
