Checking whether a spare tire is suitable for use is crucial for safety and reliability on the road. To ensure your spare tire is ready when you need it, you should regularly inspect its condition, pressure, and compatibility with your vehicle.
How to Determine If a Spare Tire Is Suitable for Use
What Is the Condition of the Spare Tire?
Begin by examining the physical condition of your spare tire. Look for any visible damage, such as cracks, punctures, or bulges. A damaged tire can be unsafe and should not be used. Check the tread depth using a tread depth gauge or the penny test: insert a penny into the tread with Lincoln’s head upside down. If you can see the top of Lincoln’s head, the tread is too worn, and the tire should be replaced.
Is the Spare Tire Properly Inflated?
Tire pressure is essential for the safe operation of any tire, including spares. Use a tire pressure gauge to check the inflation level. Most spare tires require a higher pressure than regular tires, typically around 60 psi, but always refer to your vehicle’s manual for the recommended level. An under-inflated tire can lead to poor handling and increased risk of a blowout.
Is the Spare Tire Compatible with Your Vehicle?
Ensure your spare tire is the correct size and type for your vehicle. Some cars come with a full-size spare, while others have a compact or "donut" spare. A full-size spare can be used like a regular tire, but a compact spare is only meant for temporary use, usually limited to speeds of 50 mph and distances of 70 miles. Check your vehicle’s manual for specific guidelines.
How to Maintain Your Spare Tire
Regular maintenance of your spare tire can prevent unwelcome surprises. Here are some tips:
- Inspect monthly: Check the tire pressure and physical condition at least once a month.
- Rotate if necessary: If you have a full-size spare, include it in your regular tire rotation schedule.
- Replace after use: Compact spares should be replaced after use, even if they appear undamaged.

How often should I check my spare tire?
It’s advisable to check your spare tire every month. Regular inspections ensure that the tire is in good condition and properly inflated, which is crucial for safety.
Can I use any spare tire for my car?
No, you should use a spare tire that is specifically designed for your vehicle. Using an incorrect size or type can affect vehicle handling and safety. Always refer to your vehicle’s manual for the right specifications.
What should I do if my spare tire is flat?
If your spare tire is flat, inflate it to the recommended pressure. If it does not hold air, it may need to be repaired or replaced. Never use a flat or damaged spare tire.
How long can I drive on a spare tire?
The duration you can drive on a spare tire depends on its type. A compact spare is typically limited to 50 mph and 70 miles. Full-size spares can be used like regular tires but should be replaced or repaired as soon as possible.
Is it safe to drive with a spare tire in winter?
While a spare tire can be used in winter, it may not provide the same level of traction as winter tires. If you live in an area with harsh winter conditions, consider having a full-size spare with appropriate tread for winter driving.
Conclusion
