How fast should I go with my spare tire?
Driving with a spare tire can be a stressful experience, especially if you're unsure about the limitations of your temporary replacement. At Kevin's Autos, we’ve seen countless cases where improper use of a spare tire led to further damage or safety risks. In this article, we’ll explain how fast you should drive with a spare tire and why adhering to these guidelines is crucial for your safety and your vehicle’s health.
Understanding the Types of Spare Tires
Before diving into speed recommendations, it’s important to understand the type of spare tire your vehicle is equipped with. Most vehicles come with one of the following:
- Full-Size Spare: This is a regular tire that matches the size and specifications of your other tires. It can be used like a normal tire but may not always match the wear of your existing tires.
- Compact Spare (Donut): These are smaller, lightweight tires designed for temporary use. They are not built for long distances or high speeds.
- Run-Flat Tires: These are specialized tires that allow you to drive for a limited distance even after a puncture. They don’t require immediate replacement but still have speed and distance limitations.
Speed Recommendations for Spare Tires
The speed you should maintain depends on the type of spare tire you’re using. Here’s a breakdown:
- Full-Size Spare: If you have a full-size spare, you can generally drive at normal speeds. However, it’s still a good idea to check the tire pressure and ensure it matches the other tires before driving long distances.
- Compact Spare (Donut): For compact spares, the recommended maximum speed is typically 50 mph (80 km/h). These tires are not designed for high speeds or extended use, so exceeding this limit can lead to tire failure.
- Run-Flat Tires: Run-flat tires usually allow you to drive up to 50 mph (80 km/h) for a distance of about 50 miles (80 kilometers). Always refer to your vehicle’s manual for specific guidelines.
Why Speed Matters
Driving too fast on a spare tire can lead to several issues, including:
- Reduced Stability: Spare tires, especially compact ones, don’t provide the same level of traction and stability as regular tires.
- Increased Wear: Compact spares are made from less durable materials and can wear out quickly if driven at high speeds.
- Risk of Blowout: Exceeding the speed limit for your spare tire increases the risk of a blowout, which can be dangerous and costly.
Tips for Driving Safely with a Spare Tire
To ensure your safety and minimize the risk of damage to your vehicle, follow these tips when driving with a spare tire:
- Check the tire pressure of your spare before driving.
- Stick to the recommended speed limit for your spare tire.
- Avoid sudden braking or sharp turns, as spare tires may not handle these well.
- Replace the spare tire with a regular tire as soon as possible.
Conclusion
Driving with a spare tire is a temporary solution, not a permanent fix. Whether you’re using a full-size spare, a compact spare, or a run-flat tire, it’s crucial to follow the manufacturer’s guidelines for speed and distance.

Frequently Asked Questions
Can I drive on a spare tire for 2 days?
Temporary spare tires have limited tread life. Keeping it on your car for a day or two until your first opportunity to get to the tire store might be OK, but only if you limit driving to less than 50 miles during that time. Do not let the tread wear down to the tread wear indicators built into the spare.
What happens if you go over 50 mph with a spare tire?
Do not exceed more than 50 miles per hour speed on a spare tire. Driving too fast on a spare tire is very dangerous and can lead to very expensive (and unnecessary) repairs – this is one of the reasons why many states actually have laws governing max speeds for vehicles using spare tires.
How long will a spare tire last if not used?
It may be hidden away, but it should not be forgotten. In fact, you should check and adjust its tire pressure at least seasonally. And know that, like bread, tires do expire. “Unless specified, you should get a new spare tire at 10 years to ensure it is safe to use,” says Ryan Pszczolkowski, CR's tire program manager.
Can a spare tire last 200 miles?
You should drive no more than 50 miles on a temporary or donut spare tire if possible. If you absolutely must go longer than 50 miles, avoid driving on it longer than 70 miles. A spare tire isn't meant to completely replace a tire, rather, its purpose is to tide you over until you can properly replace it.
Is it better to have a spare tire or donut?
So which one is best for you? It's more common to find donuts in sedans or smaller vehicles. Larger vehicles such as trucks or SUVs are more likely to come equipped with a full-size spare. Because donuts are so much smaller, they would be mostly ineffective for heavier vehicles but can do the trick for a light sedan.
How long will a donut tire last?
You should drive no more than 50 miles on a temporary or donut spare tire if possible. If you absolutely must go longer than 50 miles, avoid driving on it longer than 70 miles.
