GMC S15 Spare Tire
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.
GMC S15 models manufactured in 1990 have tires with overall diameter ranging from 25.5" to 26.1", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific GMC S15 years and trims.
Listed below are compact spare tire sizes that can fit some GMC S15 vehicles based on acceptable tire diameter range of 24.7" to 26.9". Some S15 models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct GMC S15 spare tire size designated by vehicle's manufacturer.
