Saturn Ion Spare Tire

The Saturn Ion, a compact car sold by Saturn from 2002 to 2007, typically comes equipped with a compact temporary spare tire, also known as a "donut" spare. This spare tire, designed to be used in emergencies and not for extended driving, is typically smaller in size than the vehicle's regular tires. The exact size can vary based on the model and year of the Saturn Ion, so it's advised to check within your vehicle's owner manual for the precise dimensions. However, generally the Saturn Ion's spare tire is usually a T115/70D14, meaning it's meant for temporary use (T), has a section width of 115mm, an aspect ratio of 70%, is a radial tire (R), and fits 14-inch rims (14). This spare is stored in the trunk of the vehicle, often under the floorboard, and it is important to regularly check its condition and inflation to ensure it is ready for use in case of a tire emergency.

Saturn Ion models manufactured from 2003 to 2007 have tires with overall diameter ranging from 24.2" to 24.9", 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 Saturn Ion years and trims.

Listed below are compact spare tire sizes that can fit some Saturn Ion vehicles based on acceptable tire diameter range of 23.5" to 25.6". Some Ion 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 Saturn Ion spare tire size designated by vehicle's manufacturer.
