Can a spare tire expire? Yes, spare tires can expire due to age, even if they have never been used. Over time, the rubber compounds in tires degrade, affecting their safety and performance. It’s crucial to regularly check the condition of your spare tire to ensure it is safe for use when needed.
How Long Do Spare Tires Last?
Spare tire lifespan varies, but most manufacturers recommend replacing them every six to ten years, regardless of use. Factors such as storage conditions and exposure to elements can accelerate deterioration.
- Age: Tires degrade over time, even when not in use.
- Storage: Exposure to sunlight, heat, and moisture can shorten lifespan.
- Material: Rubber compounds break down, affecting integrity.
Signs Your Spare Tire Needs Replacement
Recognizing when a spare tire is no longer safe is essential for your safety. Here are some indicators:
- Cracks and Dry Rot: Check for visible cracks in the sidewall or tread.
- Bulges or Blisters: Any deformities suggest internal damage.
- Tread Wear: Even unused, tread can degrade or become uneven.
- Date Code: Tires have a DOT code indicating the week and year of manufacture.
How to Check Your Spare Tire’s Age
To determine your spare tire’s age, locate the DOT code on the sidewall. The last four digits represent the week and year of manufacture. For example, "2318" means the tire was made in the 23rd week of 2018.

Regular maintenance ensures your spare tire is ready when you need it. Here are some tips:
