I have a flat tire on my 2006 g6 I don't have a doughnut what
type of vehicle has a doughnut that will fit my g6
probably easier to take the wheel that has the flat tire off and have a friend take you over to a used tire shop so they can installed the same size tire close to the tread pattern. Spares are not long term just to get you directly to a tire shop.
Following "Tom's" advice, the shop may even be able to plug the flat for you instead of replacing the tire. Once corrected, go out and buy a spare (doughnut) so you have it for the next time a tire fails.
