What Are Run-Flat Tires and How Do They Work?

What Are Run-Flat Tires and How Do They Work?

Run-flat tires, also known as zero-pressure tires, are tires that are reinforced to support the weight of a vehicle even after losing air pressure. They have extra-strong sidewalls that allow you to continue driving for 50-150 miles at reduced speeds after a puncture.

These tires contain a support ring inside that holds the shape of the tire even when all the air has escaped. The reinforced sidewall is made of a polyamide material that provides extra support and prevents the tire from collapsing. So if you get a flat, you can safely drive to a repair shop instead of being stranded roadside.

Run-flats do come with some downsides though. They tend to be more expensive, reduce ride quality, and may wear out faster. They can also be difficult to repair or replace since not all tire shops service them. However, the added safety, security and convenience they provide could be worth it for many drivers.

To get the most out of your run-flat tires, be sure to properly maintain them. Keep them inflated to the recommended pressure, rotate them regularly, and replace them once the tread depth reaches 1/16 of an inch. Driving on run-flats once severely damaged can be dangerous, so follow the guidelines in your owner’s manual.

While run-flat tires may not suit every driver’s needs, they give you an extra measure of assurance that a flat tire won’t ruin your day. For many, that peace of mind is priceless.

The Pros and Cons of Run-Flat Tires

Run-flat tires offer some nice benefits, but also some downsides you’ll want to consider before switching.

The Pros

Run-flats allow you to continue driving up to 50 miles at 50 mph even after a puncture. No need to stop and change the tire on the side of the road. They’re also more durable and less prone to damage from potholes or debris.

The Cons

Run-flats tend to cost significantly more upfront, often a few hundred dollars per tire. They also typically need to be replaced sooner, usually within 3-5 years. Run-flats can also give a slightly rougher ride and louder road noise compared to regular tires.

Some drivers complain that run-flats don’t handle as well in snow and ice. The stiffer sidewalls don’t conform to the road surface as well. Run-flats may also be more difficult to repair or patch if damaged. Many tire shops don’t have the proper equipment or training to service run-flats.


It’s critical to keep run-flat tires properly inflated to maximize performance, handling, safety, and tire life. Run-flats lose air faster than regular tires, so check pressure at least once a month. Under-inflation severely reduces the run-flat capability and can damage the tire.

While run-flats have significant benefits for emergency roadside situations, weigh the pros and cons carefully based on your driving needs and budget. When used and maintained properly, run-flat tires can provide years of safe and dependable service.

Maintaining and Replacing Run-Flat Tires

Run-flat tires require some additional maintenance to keep them functioning properly. While the reinforced sidewalls allow you to continue driving after a puncture, the tires can still become damaged. It’s important to check your run-flat tires regularly and follow the recommended replacement schedule.

Tire pressure

Check your run-flat tire pressure at least once a month and inflate to the recommended PSI listed in your owner’s manual or on the tire placard. Under-inflated tires wear out faster, reduce fuel economy and handling. Over-inflated tires can affect braking and make the ride uncomfortable. Use a quality tire pressure gage to get an accurate reading.

Tread wear

Examine your run-flat tires for uneven tread wear which can indicate alignment or balance issues. Have your tires rotated according to the pattern recommended in your owner’s manual. This helps them wear more evenly and last longer. Most manufacturers recommend rotating every 5,000 to 10,000 miles.


Run-flat tires typically need to be replaced after 6 years regardless of tread wear due to aging and weathering. The reinforced sidewalls become more prone to damage and failure over time. Check the 4-digit date code on your tires to determine their age. The first two digits represent the week, and the last two digits represent the year they were manufactured.

It’s best to replace all run-flat tires at once to maintain even handling and braking. Mixing significantly worn run-flats with new tires can be unsafe.

While run-flat tires offer convenience in an emergency, diligent maintenance and replacement according to the recommendations will help ensure safe, reliable performance and maximize their lifespan. Regular inspections, pressure checks, rotations, and timely replacement are the keys to demystifying run-flat tire care.


So there you have it, the inside scoop on run-flat tires. While the appeal of never changing a flat tire on the side of the road is huge, run-flats do require a bit more maintenance and cost to keep them running safely. For many drivers, the pros outweigh the cons and the peace of mind is worth it.

If you do opt for run-flats, be diligent about regular tire rotations, balancing, and pressure checks to maximize performance and tread life. And if a puncture does occur, get it repaired promptly to avoid permanent damage. Run-flats can be a great choice, you just have to go in with realistic expectations about their quirks. Now you’re armed with the facts to decide if run-flat tires will give you a smoother ride down the road ahead!
