Can You Drive on a Flat Tire?
No. You should not drive on a flat tire. Doing so can be extremely dangerous for several reasons.
A flat tire significantly impacts your vehicle’s handling and control, making it difficult to maneuver and increasing the risk of losing control, especially at higher speeds. The compromised handling significantly increases the risk of an accident, putting you, your passengers, and other drivers at risk. In addition, driving on a flat tire can cause severe damage to your wheel rim, suspension, and other vehicle components, leading to costly repairs beyond the flat tire itself.
If you suspect a flat tire, pull over to a safe location as soon as possible. Turn on your hazard lights to warn other drivers of your situation and replace the flat tire with your spare tire, also known as a donut.
The only exception to this rule is run-flat tires. These tires are specially designed tires that allow you to drive for a short distance (typically 50 miles at a maximum speed of 50 mph) even after a puncture. This feature is intended to get you to a safe location or a nearby repair shop, not for regular use.

How Long Can You Drive on a Spare Tire?
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.
How Many Times Can You Use a Spare Tire?
Another important question to ask is: how many times can you use a spare tire? While there’s not an exact number of times it can be used, you’ll want to be sure to properly maintain your spare so it lasts as long as possible. Just because you’re driving with a spare tire does not mean it’s the proper replacement. Using it sparsely will ensure it lasts around 8 years as spare tires should.
How Fast Can You Drive on a Spare Tire?
Additionally, you shouldn’t drive faster than 50 mph on a temporary or donut spare tire, as they have far less traction and durability than a standard tire. You probably wouldn’t want to drive longer or faster on a spare anyway, as the typical spare can make your vehicle feel more like an airplane ambling down a runway than a car driving down a highway.
While using a spare tire allows you to get back on the road, it’s crucial to remember that they are temporary solutions. Regardless of whether your vehicle comes equipped with a compact spare or a full-size one, both have limitations and should be replaced with a proper tire as soon as possible to ensure optimal safety and performance.

How to Drive Safely on a Spare Tire
Regardless of whether your spare is a donut or a full-size spare, you’ll want to be careful while driving on it. To drive safely on your spare tire, follow these best practices:
- Check your spare tire’s pressure regularly when it isn’t in use. Spare tires often have different inflation pressure needs than your regular tires, so it’s wise to check them for proper inflation. Plus, a spare tire isn’t much help if it has low pressure.
- Give yourself extra space and time to brake. Using a spare tire can cause your vehicle’s anti-lock brake system (ABS) light to turn on, or for your ABS to not function properly. Additionally, a donut spare can lead to inaccuracies in some vehicles’ speedometers. Braking early and with extra space between you and other vehicles can ensure you’re not in for surprises.
- Be extra careful when driving in inclement weather. Spare tires don’t have advanced treads, so they aren’t able to provide the traction your regular tires would. Spares are therefore more susceptible to slipping or hydroplaning (sliding across the surface of puddles).
- Replace your spare when necessary. Replacement will depend on the type of spare you have; check your vehicle’s owner manual, or inspect the spare for more information on how frequently you should replace it. Many spare tires have a lifetime of about eight years.

Driving on a Spare Tire – The Recommendations
Driving on a spare tire is a temporary solution, allowing you to get to a repair shop after a flat tire. However, it’s essential to understand the limits of your spare tire to avoid further damage to your vehicle or risking your safety.
While some spare tires may look like regular ones, they’re typically smaller and less durable, meaning you can’t drive on them like a standard tire.
Knowing the distance and speed limits for your spare can prevent accidents and save you costly repairs.
1. Manufacturer Recommendations
Car manufacturers provide specific guidelines for how long and how fast you can drive on a spare tire, usually found in the vehicle’s owner’s manual.
Generally, compact spare tires, often called “donut” tires, are designed for short trips, often only 80 to 160 kilometers (about 50 to 100 miles).
Manufacturers also recommend driving slower speeds, usually 80 km/h (50 mph).
Ignoring these limits can cause the spare tire to wear out quickly, damage your vehicle’s suspension, or even lead to a blowout.

2. Typical Distance Limits
Most temporary spare tires are designed to last for about 50 miles (80 kilometers). This is just enough distance to get you to a repair shop or tire store.
However, if you need to push it, some spares can stretch up to 70 miles (112 kilometers), but that’s generally not advisable.
Beyond this, you risk damaging your car’s alignment, suspension, and other parts. It’s always better to replace the spare with a regular tire as soon as possible.
3. Speed Limits
When driving on a spare tire, it’s critical to stick to the manufacturer’s speed limit recommendations, typically around 80 km/h (50 mph).
Driving faster than this puts unnecessary strain on the spare tire, which is smaller and less sturdy than a regular tire.
The increased speed can lead to reduced traction, longer stopping distances and the risk of the tire failing altogether.
Staying within the recommended speed extends the spare’s life and keeps you safer.
What to Do If You Have a Flat Tire?

1. Pull Over Safely
When you realize you have a flat tire, the first step is to pull over to a safe location. Look for a spot away from traffic, such as a parking lot or the shoulder of the road.
If you’re on a highway, try to find a wide, flat area where you can stop without risking your safety. Avoid stopping on narrow shoulders or areas with heavy traffic, as these can be hazardous.
Once you’ve safely pulled over, turn on your hazard lights to alert other drivers to your situation and ensure your safety while you assess the flat tire.
2. Inspect the Tire
After you’ve stopped, carefully inspect the flat tire for visible damage or punctures. Look for objects that may have caused the flat, such as nails or glass.
If you have a spare tire and are comfortable changing it yourself, you can begin replacing the flat tire.
Ensure you have the necessary tools, such as a jack and lug wrench, and follow proper procedures to install the spare securely.
If you need more clarification about changing the tire or if the flat tire shows signs of extensive damage, it’s best to seek professional help.

3. Call for Assistance
If you cannot change the tire yourself or the situation poses safety concerns, don’t hesitate to call roadside assistance.
Many insurance policies or car warranty plans include roadside assistance services for flat tires. To expedite the process, provide the operator with your location and details about your vehicle.
Roadside assistance professionals are equipped to handle tire changes safely and efficiently, ensuring you’re back on the road as quickly as possible.
Calling for help is a good option if you need clarification on the condition of the spare tire or if you prefer not to handle the situation on your own.
