How Long (And How Far) Can You Drive on a Spare Tire? 🚗

Getting a flat tire is never convenient. Whether it happens on your morning commute or during a road trip, the first question most drivers ask is: how long can you drive on a spare tire? The short answer depends on the type of spare tire you’re using—but in all cases, spare tires are meant to be temporary solutions, not long-term fixes.

Below, we’ll break down how far you can drive on a spare tire, what factors affect that distance, and when you should replace it to avoid costly damage or safety risks.

How Long Can You Drive on a Spare Tire?

For most vehicles, the answer to how long can I drive on a spare tire is no more than 50–70 miles and no faster than 50 mph. This guideline applies specifically to temporary “donut” spare tires, which are the most common type found in modern cars and SUVs.

These spares are designed to get you safely to a tire repair shop, dealership, or trusted auto repair center. They are not designed for daily driving, highway speeds, or long-distance travel.

How Far Can You Drive on a Spare Tire? It Depends on the Type

Temporary (Donut) Spare Tire

This is the small, lightweight spare most vehicles come with.

• Maximum distance: 50–70 miles
• Maximum speed: 50 mph
• Purpose: Short-term emergency use only

Driving farther or faster than recommended can cause tire failure, poor handling and braking, and damage to your suspension or drivetrain.

Full-Size Spare Tire

Some trucks, SUVs, and older vehicles include a full-size spare.

• Maximum distance: Comparable to a regular tire if properly inflated
• Speed limits: Normal posted speeds
• Caution: If the spare is older or mismatched, it should still be replaced soon

Even with a full-size spare, it’s smart to have the damaged tire inspected and repaired as soon as possible.

Why You Shouldn’t Drive Too Long on a Spare Tire

Spare tires—especially donuts—are built differently than standard tires. They have less tread, reduced grip, and lower weight ratings.

Driving too long on a spare can lead to reduced braking performance, uneven tire wear, strain on your transmission or differential, and an increased risk of a blowout.

If your vehicle is all-wheel drive (AWD), extended driving on a mismatched spare can cause serious drivetrain damage.

What To Do After Installing a Spare Tire

If you’re wondering how long can you drive on a spare tire, the best mindset is only as long as it takes to fix the problem.

After installing a spare, drive cautiously and avoid highways if possible. Keep your speed under 50 mph, schedule tire repair or replacement immediately, and avoid heavy loads or aggressive driving.

If the tire can be repaired, great. If not, replacing it quickly will restore proper handling and safety.

Signs You Need to Stop Driving on a Spare Immediately

You should pull over and seek help right away if you notice vibration or wobbling, difficulty steering, warning lights related to traction or AWD, or the spare tire losing air. These are signs the spare is under stress or beginning to fail.

Key Takeaways for Driving on a Spare Tire

To recap, how long can you drive on a spare tire is typically no more than 50–70 miles. How far can you drive on a spare tire should be just far enough to reach a repair shop. And how long can I drive on a spare tire safely is always as little time as possible.

A spare tire is a temporary fix, not a permanent solution. Driving beyond its limits puts both your safety and your vehicle at risk.
