What is a spare tire?
A vehicle’s spare tire is an extra tire that can be used in an emergency if you experience a flat or damaged tire on the road. Spare tires are commonly stored in a vehicle’s cargo area or on the undercarriage of a vehicle, and they’ll typically have a tool kit available that you can use to install it.
Your owner’s manual should outline where your spare tire is located and what specifications you should know when it’s time to replace it.
If you use your spare tire, remember that it’s only a temporary fix until you can get to an auto shop for a more permanent replacement.
When should I replace the spare tire on my car?
Spare tires can degrade over time—even if they haven’t left their storage areas. This makes it important to periodically check their condition. If it’s time to replace your vehicle’s spare tire, here are some signs you might notice:
Visible damage: If your spare tire has visible damage, such as cracks, bulges, holes, or excessive wear, it’s not going to be a good replacement for the damaged tire currently on your vehicle.
Tire won’t hold air: You may periodically need to add air to a spare tire that’s not in use—but if it seems to be frequently losing air shortly after you’ve filled it to the recommended psi range, you may want to inspect the tire for leaks or other signs of damage.
You put your spare tire to use: Spare tires are designed to be temporary use items. After you’ve used a spare tire, it’s a good idea to equip your vehicle with a new spare tire in case you need to use one again.
How often should a spare tire be replaced?
Any time you use your spare tire, it’s a good idea to have a replacement on hand in case you’re in the unfortunate situation of having a damaged tire again.
Even if you don’t use them, spare tires don’t last forever: Spare tires can degrade over time, just like any other auto part. Experts commonly recommend replacing your vehicle’s spare tire every six to 10 years.
Remember to periodically check your spare tire: You can do so whenever you check the rest of your vehicle’s tires. Look for signs of cracking, wear, or other types of damage, and verify that its air pressure remains within the recommended range (which will often be different from the rest of your vehicle’s tires).
Can I replace my spare tire myself?
Many drivers are able to replace a spare tire themselves, while others may find this job to be more difficult. Since installing a spare tire involves using a jack, you’ll want to keep best safety practices in mind as you do so.
If you’re not comfortable taking care of this job yourself, a certified mechanic can install your spare tire for you.
