Pontiac Grand Prix Spare Tire

The Pontiac Grand Prix typically comes with a compact spare tire, also known as a ‘donut ' , which is designed for temporary use in the event of a flat tire, rather than as a permanent replacement. These spare tires are smaller and narrower than the regular tires on your vehicle, typically measuring 24.8 inches in diameter and 7 inches in width, with a bolt pattern of 5x115mm. However, size can vary depending on the year and model of the Grand Prix, so it's essential to consult your vehicle's owner manual or a tire professional to ensure you obtain the correct size.

Pontiac Grand Prix models manufactured from 1990 to 2008 have tires with overall diameter ranging from 25.2" to 27", 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 Pontiac Grand Prix years and trims.

Listed below are compact spare tire sizes that can fit some Pontiac Grand Prix vehicles based on acceptable tire diameter range of 24.4" to 27.8". Some Grand Prix 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 Pontiac Grand Prix spare tire size designated by vehicle's manufacturer.
