How to Tell If a Tire is a Run Flat
To determine if a tire is a run-flat, look for “RFT” or “Run Flat” markings on the sidewall. Check your car’s manual for run-flat tire specifications.
Ensuring your vehicle is equipped with run-flat tires is important for your safety on the road. Run-flat tires are designed to allow you to continue driving even after a puncture, reducing the risk of sudden tire failure. By following a few simple steps, you can easily identify if your tires are run-flats and enjoy the added peace of mind while driving.
Let’s explore some key indicators to help you recognize run-flat tires and understand their benefits for your vehicle.

How Run Flat Tires Work
Self-supporting Design
One of the key features of run flat tires is their self-supporting design. Unlike traditional tires that rely solely on air pressure to support the weight of the vehicle, run flat tires are constructed to have reinforced sidewalls that can provide temporary support even if the tire loses air pressure.
These reinforced sidewalls are made of strong, durable materials such as rubber and synthetic compounds. They are designed to withstand the weight of the vehicle, allowing it to continue to be driven for a certain distance even with a complete loss of air pressure.
By having this self-supporting design, run flat tires offer drivers the advantage of not being completely stranded in the event of a puncture or blowout. Instead of immediately losing control of the vehicle, the reinforced sidewalls provide enough support to allow the driver to safely navigate their way to a service station or home.
Reinforced Sidewalls
The presence of reinforced sidewalls is the fundamental characteristic that distinguishes run flat tires from regular tires. These sidewalls are specially designed to be thicker and stronger, providing the necessary support to the tire when it loses air pressure.
Typically, run flat tires have multiple layers of reinforced materials incorporated into their sidewalls. This added strength allows the tire to maintain its shape and stability even after a loss of air pressure. The reinforced sidewalls act like a cradle, providing support to the weight of the vehicle and preventing the tire from collapsing.
It is important to note that run flat tires are not invincible and have limitations. They are designed to support the vehicle for a limited distance and speed after a puncture or loss of air pressure, usually ranging from 50 to 100 miles. It is crucial for drivers to be aware of these limitations and not exceed the recommended distance or speed, as this could compromise their safety.

Identifying Run Flat Tires
Ensuring your vehicle is equipped with run flat tires is crucial for safety and peace of mind. Here are simple ways to identify run flat tires:
Look For Rft Markings
Run flat tires are typically marked with RFT on the sidewall. Check for these distinctive markings to quickly determine if your tires are designed to run flat.
Check Vehicle Manual Or Manufacturer’s Specifications
Refer to your vehicle’s manual or the manufacturer’s specifications to confirm whether it is equipped with run flat tires. This information is essential for proper tire maintenance.
Visual Inspection
When identifying a run-flat tire, conducting a visual inspection is crucial. To determine if a tire is a run-flat, look for specific markings and check the sidewalls for reinforcements.
Check For Supportive ‘ssr’ Or ‘zp’ Markings
Inspect the tire sidewalls for ‘SSR’ or ‘ZP’ markings which indicate run-flat technology. These markings denote the tire’s ability to run at a reduced speed for a limited distance even after a puncture.
Inspect Tire Sidewalls For Additional Reinforcement
Examine the sidewalls closely for additional reinforcement such as thicker rubber or support structures. Run-flat tires have sturdier sidewalls to ensure stability and performance in case of loss of air pressure.
Consultation With A Professional
When it comes to determining whether a tire is a run flat, consulting with a professional is always a wise decision. Tire specialists and certified auto mechanics have the knowledge and expertise to accurately determine if your tire is a run flat. Seeking their advice can help you make informed decisions about your tires and ensure your safety on the road.
Seek Advice From Tire Specialists
Tire specialists are trained professionals who understand the intricacies of different tire types, including run flat tires. Consulting with a tire specialist is a great starting point when you’re unsure if your tire is a run flat. These experts can examine your tires and provide you with valuable insights.
During a consultation with a tire specialist, they may check for certain visual indicators. Run flat tires often have sidewall reinforcements or reinforced beads that strengthen the tire’s overall structure. These features help the tire maintain its shape and functionality, even when it’s deflated or punctured.
In addition to visual inspections, tire specialists have access to specialized tools that can assist in identifying run flat tires. These tools can measure the thickness of the sidewalls and determine if they are within the manufacturer’s specifications.
Visit A Certified Auto Mechanic
In addition to consulting with tire specialists, visiting a certified auto mechanic is another effective way to determine if your tire is a run flat. Auto mechanics can inspect your tires and provide a thorough assessment based on their extensive knowledge and expertise.
During your visit, the certified auto mechanic may inspect the tire’s construction and look for specific attributes that distinguish a run flat tire. They might examine the tire’s inner lining, which is often made of reinforced rubber, designed to provide additional support in case of a puncture.
Utilizing specialized diagnostic tools, certified auto mechanics can also check for features such as tire pressure monitoring systems (TPMS). Run flat tires often come equipped with these systems, which can help alert you when the tire is deflating or experiencing a loss of pressure.
By seeking advice from tire specialists and visiting certified auto mechanics, you can rely on their expertise to determine whether your tire is a run flat. Their examinations and assessments will give you the confidence and peace of mind needed to make informed decisions about your tires and ensure your safety on the road.
Testing Run Flat Functionality
Ensuring that your tires are run flat capable is crucial for your safety on the road. Properly testing this functionality can provide peace of mind and ensure preparedness for any unexpected tire-related incidents. Here are some steps to assess the run flat ability of your tires.
Test Drive To Assess Run Flat Ability
Take your vehicle for a test drive on different road surfaces to observe the performance of the run flat tires in real-world conditions. Pay attention to the steering responsiveness and overall stability of the car. Note any unusual vibrations or noises that may indicate a lack of run flat functionality.
Consult Manufacturer’s Guidelines For Testing
Refer to the manufacturer’s specifications and guidelines for testing the run flat capability of your tires. Follow their recommendations for conducting specific tests, such as driving at reduced air pressure or assessing the tire’s performance under varying load conditions. Adhering to the manufacturer’s guidelines ensures a comprehensive evaluation of the tire’s run flat functionality.
