If you find yourself in a situation where your spare tire is smaller than your regular tires, it’s important to understand how to handle this safely. Smaller spare tires, often called "donut" spares, are designed for temporary use. Here’s what you should do:

1. Use the spare tire only for short distances. These tires are not meant for extended driving.
2. Limit your speed. Typically, you should not exceed 50 miles per hour.
3. Replace the spare with a regular tire as soon as possible. This ensures your vehicle remains safe and balanced.

Why Are Spare Tires Smaller?

Spare tires are often smaller for a few practical reasons. The compact design of a "donut" spare saves space in your car and reduces weight, which can improve fuel efficiency. However, this design comes with limitations.

How to Safely Use a Smaller Spare Tire

What Is the Maximum Distance You Can Drive on a Spare Tire?

While it’s tempting to push the limits, driving on a smaller spare tire should be restricted to a maximum distance of about 70 miles. This is to prevent excessive wear and potential damage to the spare, as well as to maintain the vehicle’s handling and safety.

Why Should You Limit Your Speed?

Driving at high speeds with a spare tire can be dangerous. The construction of these tires is not as robust as regular tires, and they can overheat and fail if driven too fast. Always adhere to the recommended speed limit of 50 mph.

How to Replace the Spare Tire Promptly

Once you have a spare tire installed, make it a priority to visit a tire shop. Here’s what you should do:

• Schedule an appointment with a tire service center.
• Ensure the replacement tire matches the size and specifications of your other tires.
• Have the alignment checked to ensure balanced handling.

Potential Risks of Driving on a Smaller Spare Tire

What Are the Risks of Prolonged Use?

Using a spare tire for too long can lead to:

• Increased strain on the drivetrain, especially in all-wheel-drive vehicles.
• Compromised braking performance due to the imbalance.

How Does a Smaller Spare Affect Vehicle Handling?

A smaller spare tire can alter your vehicle’s balance and handling. This can lead to:

• Reduced traction in adverse weather conditions.
• Increased stopping distance, especially if the spare is on a drive axle.

Practical Tips for Managing a Smaller Spare Tire

• Check your vehicle’s manual for specific guidance on using a spare tire.
• Regularly inspect your spare tire to ensure it is properly inflated and in good condition.
• Consider investing in a full-size spare if you frequently drive long distances or in remote areas.
