Can you put air in run-flat tires? Yes, you can and should put air in run-flat tires. Although these tires are designed to allow you to continue driving temporarily after a puncture, they still require proper air pressure for optimal performance, handling, and safety.
Run-flat tires are a remarkable innovation in the world of automotive technology. They are designed to provide continued mobility even after they have been punctured or have lost air pressure. This unique feature allows drivers to continue driving for a limited distance (usually up to 50 miles) at reduced speeds, even after a blowout. While this can be extremely beneficial in emergency situations, many drivers mistakenly believe that run-flat tires don’t need air or that they can function without regular maintenance.
However, while run-flat tires are designed to support the vehicle’s weight temporarily without air, they still require proper air pressure to perform at their best. A well-inflated run-flat tire ensures optimal safety, handling, and longevity. Neglecting to maintain the correct tire pressure can lead to poor handling, increased tire wear, and even the potential for serious damage to the tire’s structure.
This guide will discuss everything you need to know about putting air in run-flat tires, how to maintain proper tire pressure, and the common misconceptions about their maintenance.

Technology Behind Run-Flat Tires
Run-flat tires are built with a reinforced sidewall that allows them to continue supporting the vehicle’s weight even after a puncture or loss of air. Unlike conventional tires, which lose their structural integrity once deflated, run-flat tires can carry a load without air pressure for a limited distance.
There are two types of run-flat tire technology:
- Self-Supporting: These tires have thick, reinforced sidewalls that can bear the weight of the car even when the tire is deflated.
- Support Ring: These tires use a rigid ring inside the tire, often made from rubber or plastic, that supports the weight of the vehicle when the tire loses air.
Both types of run-flat tires offer the ability to continue driving without air, but they do not eliminate the need for regular maintenance, especially when it comes to air pressure.
Importance of Maintaining Air Pressure in Run-Flat Tires
Maintaining the correct air pressure in run-flat tires is essential for their safety and performance. In this section, we’ll explore why proper inflation is important for maximizing the benefits of run-flat tires and ensuring your vehicle’s safety.
1. Ensuring Optimal Performance
Despite their ability to function without air temporarily, run-flat tires still require proper air pressure to perform optimally. Proper tire inflation ensures that the tires maintain their grip on the road, provide stability, and offer the best fuel efficiency. Running a tire with insufficient air pressure can lead to poor handling and braking performance, putting you at risk in dangerous driving conditions.
2. Safety Considerations
Maintaining proper air pressure in your run-flat tires is important for the safety. While these tires are designed to allow you to continue driving after a puncture, driving with low air pressure can cause the tires to overheat. This overheating can lead to further damage to the tire structure, potentially causing the tire to fail. Additionally, improper inflation can cause the vehicle to handle poorly, especially during sharp turns or emergency maneuvers.
3. Preventing Further Damage
Even if your run-flat tire has been driven on after losing air, it still needs to be properly inflated and inspected regularly. Driving with a deflated tire for extended periods can damage the tire’s internal structure, making it impossible to repair and necessitating a replacement. This can lead to unnecessary costs and delays when it comes to getting the vehicle back on the road.
How to Check and Inflate Run-Flat Tires
Checking and inflating the run-flat tires is a simple yet important task to ensure they perform optimally. The necessary steps to check the tire pressure and properly inflate the run-flat tires.
1. Checking the Tire Pressure
The first step to maintaining your run-flat tires is to regularly check their air pressure. Here’s How to Check Tire Pressure.
2. Inflating the Run-Flat Tires
- Attach an Air Compressor: Once you’ve checked the PSI, if the air pressure is low, use an air compressor to inflate the tire to the correct PSI.
- Recheck the Pressure: After inflating the tire, recheck the pressure to make sure it matches the recommended PSI.
- Replace the Valve Cap: Once the correct air pressure has been achieved, replace the valve cap to prevent dirt or moisture from entering the valve stem.
Common Myths About Run-Flat Tires
There are several misconceptions about run-flat tires that can lead to confusion and improper maintenance. In this section, we will debunk some of the most common myths and provide you with the correct information to ensure the run-flat tires perform as intended.
1. “Run-Flat Tires Don’t Need Air”
While it’s true that run-flat tires can temporarily function without air, they still need to be properly inflated to perform at their best. Running them with low air pressure can cause the tires to overheat and lead to failure, which could put you at risk of an accident.
2. “You Can Drive Indefinitely on a Deflated Run-Flat Tire”
Many people mistakenly believe they can drive forever on a run-flat tire without air. While these tires are designed to support the vehicle’s weight for a limited distance (usually 50 miles), continuing to drive beyond that limit can cause internal damage to the tire. This may render the tire unrepairable and require replacement.
Frequently Asked Questions
Here are some FAQs about putting air in run-flat tires –
1: How often should I check the air pressure in my run-flat tires?
It is recommended to check your run-flat tires’ air pressure at least once a month and before long trips to ensure proper inflation.
2: Can I repair a punctured run-flat tire?
If the puncture is within the tread area and hasn’t caused significant internal damage, the tire can often be repaired. However, if the tire has been driven without air for too long or the damage is on the sidewall, it may need to be replaced.
3. Can I use a regular air compressor to inflate my run-flat tires?
Yes, you can use a regular air compressor, as long as it is capable of inflating the tire to the required PSI.
4: Are run-flat tires more expensive than regular tires?
Yes, run-flat tires are generally more expensive due to their advanced technology and construction, which allows them to function without air temporarily.
5: Can I mix run-flat tires with regular tires on my vehicle?
It is not recommended to mix run-flat and regular tires on the same vehicle. This can affect vehicle handling, especially in an emergency situation, and cause safety issues.
Conclusion
While run-flat tires offer the convenience of continued driving after a puncture, they still require regular maintenance, including proper air inflation. Maintaining the correct air pressure in your run-flat tires is essential for optimal performance, handling, and safety.
Regularly check the tire pressure, inflate as needed, and ensure that the tires are always ready when you need them most. With the right care, your run-flat tires will continue to provide the reliability and convenience they were designed for.
