2012 Jeep Grand Cherokee Spare Tire

The Jeep Grand Cherokee comes equipped with a temporary compact spare tire that's specifically designed for emergency use in case of a flat tire. This spare tire, often called a "donut," is smaller than the vehicle's standard tires, typically 18 inches in size, but can vary depending on the model and year of the Grand Cherokee. While it's not designed for long-term or high-speed use, the temporary spare should keep the vehicle operational until the primary tire can be repaired or replaced, ensuring drivers aren't stranded with a flat. It ' s important to note that the spare tire size should match the size recommended in the owner's manual or the information placard located on the driver's side door jamb to prevent any potential damage to the vehicle's differential. It ' s also crucial to maintain appropriate tire pressure in the spare tire, as outlined in the vehicle's manual.
