The GMC S15, a compact pickup truck produced by General Motors, typically comes with a spare tire designed as a temporary solution for a flat tire and should be replaced as soon as possible. The compact spare tire, also known as a "donut," is designed to fit neatly in the allocated space within your vehicle, usually located in the trunk, under the cargo area, or hanging beneath the back of the vehicle. The exact size of the spare tire varies depending on the model year of the GMC S15. However, the typical size is likely to be slightly smaller than the regular tires and could possibly be a different width. It's important to note that the GMC S15 spare tire should only be used for emergencies and should be driven at lower speeds due to its smaller size and different construction.
