Flat tires are one of the most common car issues drivers face, but there are steps you can take to minimize the risk. Knowing what to do in the event of a flat tire and how to prevent it will keep you, your passengers, and other drivers safer on the road. Below, we’ll cover everything from the most important flat tire facts to practical steps for dealing with a flat.

What Causes a Flat Tire?

Flat tires can happen for a variety of reasons, even if you maintain your vehicle properly. Some of the most common causes of flat tires include:

  • Road debris: Sharp objects like nails or glass on the road are one of the most frequent causes of flat tires. This kind of damage can cause an instant tire blowout, but it can also cause slower, harder-to-detect leaks that get worse over time.
  • Weather conditions: Extreme heat or cold can damage your tires. Cold weather may cause tires to contract and leak air, while heat causes tires to expand, leading to leaks, or even tire bursts.
  • Damaged valves: Valves damaged during tire installation or while refilling can cause air loss, resulting in a flat.
  • General wear and tear: As tires age, they become more susceptible to damage. Regularly checking tread wear can help you know when it’s time to replace your tires.
  • Overinflated tires: Too much air pressure can cause tires to leak or become damaged internally. Always check your tire pressure with a gauge and follow the recommended PSI.

Ways to Prepare for and Prevent a Flat Tire

Taking steps to prevent flat tires can save you time, money, and stress. Here are some ways to reduce the likelihood of encountering a flat:

Have the Right Equipment and Practice Tire Repair

Knowing how to change a tire and practicing the process will make you more confident when the time comes. Making mistakes like leaving the lug nuts too loose, crawling under the car or placing your jack on the plastic part of your car frame can all lead to unnecessary injuries and damages.

If you’re unsure where to place your jack or other car-specific information, consult your owner’s manual.

Get Roadside Assistance

You can sign up for roadside assistance with your own insurance company, a third-party provider or your credit card company. Roadside assistance companies offer a number of benefits and services, including:

  • Emergency medical assistance
  • Flat tire replacement
  • Fuel refills
  • Jump starts
  • Towing
  • Winching

Some of the biggest roadside service companies include AAA, AARP, Motor Club of America and the Allstate Motor Club Membership.

DID YOU KNOW?

If you have a Visa, Mastercard or Chase card, you can sign up for roadside assistance with rates starting at around $60 per service.

Maintain Your Tires

You can reduce your risk of getting a flat by having proper tire maintenance and safe driving habits, like driving slowly through construction zones. Some of the biggest things you can do to keep your tires safe include:

  1. Check your tire pressure: The NHTSA suggests using a pressure gauge once a month to ensure proper tire pressure. The recommended pressure is usually located on the driver’s side door or along the door jamb. 
  2. Rotate your tires: Switch the front tires to the back and vice versa. You can have a mechanic do it for you, but Edmunds recommends rotating tires every 5,000 to 8,000 miles to give the front tires a break from the regular wear and tear they endure, especially for front-wheel-drive cars.
  3. Avoid driving over road hazards: If you can, avoid road hazards, such as potholes, metal, glass, nails and other road debris. 
  4. Avoid overloading your vehicle: If you have to carry a heavy load when moving or going camping, you may want to increase your tire pressure to the maximum recommended number.
  5. Check your tires for recalls: You can use this NHTSA tool to check for key recall dates on your vehicle. Most tires have a recommended manufacturer lifetime before they become a hazard to drive on and some manufacturers will offer a replacement for free if you can verify your tire is defective. 

What to Do if You Have a Flat Tire

It’s important to have a plan if you encounter a flat tire on the road. Following the steps below will ensure you maneuver your vehicle in the safest manner and do as little damage as possible to your car:

  1. Don’t slam the breaks: Your instinct might be to slam the breaks when you feel/hear the thumping sound of a flat tire. But if you slam your brakes, you could lose control or damage your vehicle. Instead, turn on your hazards, slow down to about 20 miles per hour (mph), and find a safe spot to pull off on the side of the road.

FYI:

Although a simple tire patch-up can cost $30 to $60, driving on a flat tire could lead to other vehicle damages, such as structural wheel damage, brake damage or alignment issues, which cost thousands of dollars.3

  1. Don’t drive on a flat: Unless you have a flat-run tire, you should not drive on a flat tire. You could cause further damage to your car or get into an accident.
  2. Change the Tire (If You Can): If you feel confident and have the right equipment, follow these steps to replace your tire:
    • Ensure the car is in a safe spot and turn on your hazard lights.
    • Grab your spare tire and car jack (usually located in your trunk). You’ll need this to elevate your car high enough for you to remove the old tire and replace it with a new one.
    • If you have safety reflectors to alert other drivers to your presence on the road, place these in appropriate locations.
    • Loosen the lug nuts with a lug wrench, but don’t remove them completely yet.
    • Lift the car using the jack, ensuring it’s at least six inches off the ground.
    • Remove the lug nuts and the flat tire, then mount the spare tire.
    • Hand-tighten the lug nuts onto the spare tire, lower the car back to the ground, and finish tightening the nuts securely.
    • Once your new tire is installed, check its PSI using a pressure gauge. The recommended PSI should be indicated on the spare tire or on your car’s inside door frame.
  3. Call for help: If you don’t know how to change a flat, call for help! Reach out to family, friends or your roadside assistance provider if you have one. More on roadside assistance options below.

DID YOU KNOW?

According to Consumer Reports, only 10 percent of new cars since 2020 come equipped with a spare tire. Around 50 percent are fitted with a temporary, space-saver tire, and the rest are not fitted with anything at all.4

Flat Tire Facts and Figures

Flat tires lead to hundreds of fatalities per year. The numbers below underscore just how important tire safety, maintenance and preventative measures are in the United States:

  • According to the National Highway Traffic Safety Administration (NHTSA), tire blowouts and tire-related issues cause about 11,000 to 33,000 accidents every year in the U.S.
  • In 2022, there were over 560 traffic fatalities from tire-related car crashes.5
  • 26 percent of drivers do not know how to change a flat tire. Of those who do 57 percent have changed a tire themselves, and 22 percent called roadside assistance for help.6
  • You can drive about 50 miles on a run-flat tire, which are tires designed to run for short distances after being punctured. According to Edmunds, run-flat tires are standard on only 15 percent of vehicles.7
  • AAA responds to over 3.5 million flat tire calls each year.

Recap

Flat tires can be unpredictable, stressful and dangerous situations to navigate. However, with a bit of preparation and planning, you can easily acquire the tools and knowledge to manage a flat tire. Regular tire maintenance, knowing how to change a tire, having roadside assistance, and taking proactive measures will keep you safer on the road and can save you money in the long run.

Frequently Asked Questions

How do run-flat tires work?

Run-flat tires are reinforced with a sidewall design that keeps the tire running even after it’s been punctured. The additional support allows you to drive for about 50 miles on a flat tire.

Why do my tires keep going flat?

Here are some of the most common reasons why you might be experiencing a recurring flat tire:

  • Loose valve stems
  • Tire puncture from glass, nails or another sharp object
  • Poor tire damage repair
  • Dry rot
  • Old tires
  • Wear and tear
  • Temperature fluctuation (usually when it gets hot)

How much do run-flat tires cost?

According to CARFAX, a run-flat tire can cost anywhere from $150 to $500. Rates for regular tires start at about $50.

How can I tell if my tires are run-flat?

Run-flat tires can usually be identified by markings on the sidewall. Depending on the brand, you can determine if your tire is a run-flat based on whether you can see the following markings on the tire:

  • Bridgestone: RFT
  • Continental: SSR
  • Dunlop: ROF
  • Goodyear: ROF or EMT
  • Michelin: ZP
  • Pirelli: RSC

What Should I Look for in A Flat Tire?

Flat tires typically run closer to the ground than other tires. The tire wall may have cuts or punctures. When driving, you may feel the car vibrate or pull to one side. Your TPMS (Tire Pressure Monitoring System) may come on. Some tires may have small, slow leaks that are harder to detect. If you are unsure if your tire is flat, we recommend checking the air pressure using a pressure gauge.
