1990 Pontiac Sunbird Spare Tire
The Pontiac Sunbird, a small car manufactured by Pontiac from 1975 to 1994, typically comes equipped with a compact spare tire, also known as a "donut" spare, stowed away in the trunk. This type of tire is smaller and lighter than regular tires, designed mainly for short term and emergency use, as it doesn't have the same durability and longevity. The key purpose of such a tire is to get you to a safe place or a nearby mechanic for a permanent tire replacement. The size of the spare tire, similar to the original tires, typically depends on the model and manufacturing year of the Pontiac Sunbird. As a good practice, one should look at the tire's sidewall for specifications like width, aspect ratio, and diameter, usually marked as P225/60R16, for instance. However, always refer to your vehicle's user manual or consult a professional to ensure you have the correct spare tire size for safety and optimal car performance.
1990 Pontiac Sunbird comes with 3 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Pontiac dealership to confirm the correct 1990 Pontiac Sunbird spare tire size.
