What is a Spare Tire?
A spare tire is a backup tire designed to temporarily replace a flat or damaged tire. It allows you to continue driving your vehicle to the nearest repair shop or safe location. Spare tires come in various types, each with specific characteristics and limitations.
Typically, spare tires are smaller and lighter than regular tires, which makes them easier to store in your vehicle. However, they are not intended for long-term use and may have speed and distance restrictions. Understanding what type of spare tire your vehicle has is crucial for its proper use.
Types of Spare Tires
There are mainly two types of spare tires:
- Full-Size Spare: These are identical to the regular tires on your vehicle. They provide the same performance but take up more storage space.
- Donut Spare: These are compact and lightweight options designed for temporary use. They are more common in modern vehicles due to their space-saving design.
Can You Drive on a Spare Tire?
Yes, you can drive on a spare tire, but only for a limited time and under specific conditions. Spare tires are not built for prolonged use. They are intended to get you to a repair shop or a safe location where you can replace your damaged tire.
Driving on a spare tire for an extended period can lead to safety risks, such as reduced traction, uneven wear, and potential damage to your vehicle's suspension system. Always prioritize getting your regular tire repaired or replaced as soon as possible.
How Long Can You Drive on a Donut Spare Tire?
The general guideline for donut spare tires is that you should not drive more than 50–70 miles. This limitation ensures that the spare tire does not experience excessive wear or compromise the safety of your vehicle.

It’s also important to consider the age of your spare tire. Even if unused, tires can degrade over time due to environmental factors. Check its condition before relying on it during an emergency.
How Fast Can You Drive on a Spare Tire?
Speed limits for spare tires vary depending on the type, but most donut spares are designed for speeds of up to 50 mph. Exceeding this speed can compromise the tire’s structural integrity and increase the risk of an accident.
Full-size spares, on the other hand, may allow for regular driving speeds. However, always consult your vehicle’s manual for specific recommendations to ensure safe driving.
What Happens if You Drive Too Long on a Spare Tire?
Driving too long on a spare tire can lead to several issues:
- Increased wear on the spare tire
- Damage to your vehicle's suspension system
- Reduced fuel efficiency
- Compromised braking and handling
Ignoring these risks can escalate into costly repairs or even accidents.
Steps to Safely Install a Spare Tire
Follow these steps to safely install a spare tire:
- Park your vehicle on a flat, stable surface.
- Engage the parking brake and turn on your hazard lights.
- Loosen the lug nuts on the damaged tire before using the jack.
- Lift the vehicle with the jack and remove the lug nuts completely.
- Replace the flat tire with the spare and tighten the lug nuts by hand.
- Lower the vehicle and tighten the lug nuts securely.
Maintaining Your Spare Tire
Regular maintenance of your spare tire ensures it is ready for use when needed. Here are some tips:
- Check the tire pressure monthly.
- Inspect for wear or damage periodically.
- Replace the spare tire if it shows signs of aging or deterioration.
When Should You Replace a Spare Tire?
Replace your spare tire if:
- It has visible cracks or damage.
- It is more than 7–10 years old.
- You have used it extensively and it shows signs of wear.
Does Using a Spare Tire Affect Your Vehicle?
Yes, using a spare tire can affect your vehicle’s performance. For instance:
- Donut spares can cause uneven weight distribution.
- Handling and braking may be less effective.
- Full-size spares may still lead to subtle performance changes if they are not identical to your regular tires.
How to Prevent Flat Tires
Preventing flat tires can save you from relying on your spare. Here’s how:
- Regularly check tire pressure.
- Inspect for wear and tear.
- Avoid driving over sharp objects or potholes.
- Rotate your tires as recommended by the manufacturer.
