Ever had a flat tire and wondered if your spare can take you all the way? Most drivers never consider their spare tire until the moment something goes wrong and they require it, but if you know how far it can get you, that can make or break your road trip and your safety. In this blog, we will be discussing what all drivers should know: the different types of spare tires, how long a spare tire lasts, the spare tire age limit, the most important factors that influence durability, and advice for examining and replacing your spare before it leaves you stranded.
Types of Spare Tires
Do you know that not all of the spare tires are created equal? Yes, that is right. You just need to know a few of them that are given below:
Temporary (Donut) Spare:
These are compact and lightweight tires that are designed specifically for emergency use. These spare tires are only meant for short distances and low speeds.
Full-Size Spare:
Full-size spare tires match the original tires on your car, which provides reliable performance and safety over longer distances. It takes up more trunk space but can be used as a regular tire for more extended periods.
Run-Flat Tires:
These days some newer cars omit the spare and have run-flat tires instead. Even if they get punctured, these allow you to continue driving for 50 miles at decreased speed.

Factors That Affect Spare Tire Lifespan
A question that always keeps moving inside the heads of car owners is, how long does a spare tire last? It has many factors involved, and it does not matter how much (or little) your spare gets used:
- Tire Age: The “spare tire age limit” is typically 6–10 years. Actually, the rubber that is not used can degrade over time.
- Storage Conditions: If it is exposed to conditions like heat, sunlight, or wetness in the trunk or undercarriage, then it will cause it to age faster.
- Air Pressure: All types of spares need frequent air checks, and it is to be noticed that compact spares use up to 60 psi.
- Driving Conditions: It is a key point to be taken into consideration that the weight that you are carrying and the roads that you are driving on, like gravel, highway, etc., all come into play.
Signs a Spare Tire Needs Replacement
It is the time to replace the spare tire, but you are not aware of it, and this can cost you heavily. For this awareness and knowledge is the key. Here’s what to look for:
- Cracks/Dry Rot: Check the sidewalls and tread for cracks or rotting rubber.
- Tread Depth: For full-size spares, low tread means replacement time.
- Air Leaks or Deformities: Any air loss or visible bulges are warning signs.
- Expiry Date: Look for the manufacturing date on the sidewall. If it is past the age limit, even if unused, then it is time for replacement.
Tips for Maintaining Your Spare Tire
Some of the helpful tips that would help you to maintain your spare tire are:
- Check the tire pressure of the tire regularly, and if you do it monthly, it is best.
- Store the spare tire in a cool and dry place like a trunk or dedicated mount.
- Rotate a full-size spare with your regular tires during routine maintenance.
- Replace any old or unused spare tire after 6–10 years, even if it looks fine from the outside.
How to Use a Spare Tire Safely
- Only make quick trips on a donut and get your main tire serviced as soon as you can.
- Steer clear of highways and keep your speed down with run-flat and temporary spares.
- When using a spare, especially a small one, don’t overburden your car.
FAQs
1. How long does a spare tire last if never used?

Yes, you should replace an unused spare tire if it is over the spare tire age limit or shows any damage.
3. How often should I check my spare tire?
You should check your car’s spare tire every month when you check your other tires or before any long road trip.
4. Can I drive normally on a full-size spare?
