Most car owners will find themselves by the side of the road with a tire failure at some point due to a screw, nail, or other sharp objects.

You can easily store this product in the trunk or other area of your vehicle for emergencies. The best tire sealants are affordable and easy to use, but they're not all created equally.

I took several factors into consideration when choosing the best tire sealants. First, I focused on well-known brands that have a reputation for producing high-quality products. I also looked at the effectiveness of each item. Using user testimonials as a reference, I compared how each sealant performed in real-world conditions in order to determine how well they functioned overall.
I included products that are both solutions to a puncture and I made sure to pick products that can be used on a variety of different tires, from passenger cars to larger pickup trucks. I also included items in a wide range of prices to suit a variety of budgets. For more information on our methodology, go here.
Slime Emergency Tire Repair Sealant
SEE IT
While the name may be gross, Slime tire sealant is one of the most effective sealants on the market.
It is capable of filling punctures up to 1/4-inch, which is around the size of a normal screw or nail. It’s a great preventative measure to help fight against the possibility of full tire blowouts.
This small and powerful formula is fit for cars, trucks, SUVs, ATVs, trailers, and RVs. Plus, it’s compact enough to take with you, no matter where you plan on driving. One of the best features we found is that the bottle comes with its own valve core removal tool, giving you easy access to prevent leaks in your tires.
However, if you are using it for a car or trailer, there is a restriction on how fast you should drive. It’s only effective at speeds up to 65 mph, and should only be used as a quick fix if you tend to drive at speeds around this mark.
Fix-A-Flat Tire Sealant and Car/SUV Tire Inflator
SEE IT
This simple small yet effective tire sealant is capable of making sure a large tire holds its air until you get it properly taken care of.
Its compact bottle means you can take it with you and quickly use it in case you have a tire emergency. You can easily check what tires Fix-A-Flat fits by checking out the guide on their website.
It is able to fully block a puncture up to 1/4-inch. While it isn’t a permanent fix, it will last long enough for you to drive it to the shop or back home. It’s easy to attach to your tire nozzles as well, giving you more time to get back on the road and less time worrying about how much air you’ve lost. It’s nontoxic, noncorrosive, and nonflammable as well, making it safe for the environment. It’s also safe to use on cars with a TPMS monitoring system.
While it may be fast-acting, you will have to move the car to the right position in order for the compound to take hold effectively. That means you have to make sure to park where the puncture is at the six o’clock angle, which can be difficult to do by yourself.
TireJect Tire Sealant Kit
SEE IT
When ordering this tire sealant, you have the option of choosing 10, 20, or 40 ounces.
You can also choose to order a one-gallon container. The sealant is a liquid rubber mixture that contains tire particles and Dupont Kevlar fibers. Every 10 ounces of sealant comes with one bladder bag and one injector tool. You can use this repair kit to repair punctures in your tires from screws, nails, thorns, or anything else. The sealant only works on punctures that are up to 3/8-inch.
You’ll find this sealant system is easy to use, thanks to the included injector tool. You connect it to your valve stem for a mess-free installation. You can even install this sealant on all four of your tires and prevent future flats for the next year.
Ride-On Motorcycle Tire Balancer & Sealant
SEE IT
This tire sealant is meant for use with motorcycle tires.
It will balance and seal your tire by evenly coating the inside surface of your tire. If your tire suffers a puncture while you’re riding, the centrifugal force of your rotating tire and the internal air pressure will move the Ride-On sealant into the hole. This will instantly seal it. This will work on punctures that are up to 1/4-inch in tubeless tires and 1/8-inch in tube tires.
You’ll like that this sealant turns your tires into self-sealing tires. They’ll also eliminate the need for ugly wheel weights. This sealant is specifically designed for use in high-speed tires. It’ll improve the performance of your motorcycle tires by dampening road vibration and noise.
Berryman Products Seal R Tire Sealing Compound
SEE IT
This tire sealant comes in a variety of sizes based on your needs: 8, 16, or 32 ounces or a one-gallon container.
It will instantly seal your pneumatic tires and tubes. It protects against thorns, screws, and any other sharp objects. To use, extend the included hose and attach it to your tire valve. Then use the reliable pump action nozzle to dispense the sealant into your tire.
What’s nice about this sealant is that it specifically states that it’s safe for use with a variety of metals. This includes chrome, steel, and alloys used in wheel making. You can confidently use this sealant without worrying that it will ruin your wheels. It also stays liquid and won’t corrode or cause rust.
Slime Smart Spair Emergency Tire Repair Kit
SEE IT
The Slime 50107 Kit contains two distinct elements: a powerful tire inflator and the emergency tire repair sealant.
Instead of having to use a jack to change out the punctured tire, leave that hassle behind. The sealant is tire sensor safe and works well with standard car tires. The Slime tire sealant repairs tread area punctures up to 1/4-inch in diameter. Along with the kit’s included inflator, you can repair and inflate the tire within 15 minutes. Simply plug the tire inflator into your vehicle’s 12-volt accessory power outlet to get it started. It features a quick connect air hose and a built-in tire pressure dial gauge. The 16-ounce bottle of the emergency non-toxic tire sealant instantly seals punctures. The process is simple and hassle-free.
However, some users have experienced issues with the product going dead and not working when they needed it. Some actually lost more air after using this sealant.
STP Car Tire Fix Sealant and Tire Inflator
SEE IT
Whether you drive a car or truck or ride a motorcycle, STP Tire Fix Sealant and Inflator works well without any tools required.
The non-flammable formula seals punctures that are up to 1/4-inch in diameter, it is easy to clean up with water, and it will hold air for as long as three days.
The product is also safe to use with tire pressure monitoring sensors. We like that this product is so easy to use: just fill up the tire to seal and inflate it, and go. Sixteen ounces fills a standard-sized tire, while 20 ounces fills larger tires. Overall, it's great for emergencies and is a short-term solution. The company recommends going to a repair shop for inspection and a permanent fix within a couple of days after application.
Slime Emergency Tire Repair Sealant is well-known in the industry and can repair screw or nail punctures up to 1/4-inch long. It can be used on cars, trucks, SUVs, ATVs, RVs, and more. It includes a valve core removal tool to make the process easier.
For a slightly more budget-friendly option, consider the equally effective Fix-A-Flat Tire Sealant and Car/SUV Tire Inflator.
Aerosol tire sealant is one of only two types. A single-use product, aerosol sealant is for emergency repairs that will allow you to drive short distances on a punctured tire. It comes in a bottle that sprays, allowing a simple application to fill holes in the tire with great accuracy. When you spray the product into the valve, the punctured tire will inflate. The formula coats the inside of the tire to plug any leaks or holes.
The second type of sealant for a punctured tire comes in the form of a thick gel.
Using the gel option can be a bit more difficult than the aerosol tire sealant, as it is harder to put in place. Plus, it can be messier due to its slimy substance. To use the gel sealant, you will usually need tools or equipment to make sure the tire is properly sealed and no longer leaking air.
Many tire sealants are very affordable and cost between $10 and $20. These products are often at least 16 ounces in size and work as promised. They are no-frills, but they get the job done. If you spend upwards of $60, you will often find much larger sealant containers or those that are part of a kit, which can include items such as tire inflators. If you have room in your vehicle for a kit, it may be worth storing one in your trunk due to the added features, such as accessories for inflatable and carrying bags.
You’ve got questions.
The Drive has answers.
Tire sealants are for temporary use and not a permanent solution. The tire sealant’s purpose is to get you to the nearest gas station, automotive shop, or dealership to fix the tire. Depending on the amount of damage to the tire, you may need to get a brand-new tire put on the vehicle.
Tubeless tire sealant should last an average of two-six months. However, the life span depends on several factors, such as temperature, humidity, driving frequency, tire casing thickness, and the number of punctures.
This depends on the type of tire sealant and the brand. Each product should state how long they last, but generally they can last up to two years before needing to replace the tires.
A: This varies on the size of the tire you are trying to fill the puncture in.
A lawn mower tire is smaller and therefore doesn’t need that much product. However, a Jeep tire is larger and will typically need an entire bottle of tire sealant.
A: You inject the tire sealant through the valve or tire nozzle. After completing that step, you then fill the tire with air until it is at the required amount.

Tire sealants are nifty products to have around in case of a flat tire or slow leak and should be part of an emergency tool kit for mountain bikers, ATVs, or any vehicle with off-road tires.
Keep in mind that the centrifugal force can become off balance when the sealer is added to the tire until it's evenly distributed. To do this, simply allow the wheel to turn for several minutes slowly.

Most sealers are not intended for highway use, although some brands can be used as soon as the sealer is properly distributed inside the tire to reduce any wobble. Certain factors such as location, which affect surface temperature and the tire quality of the vehicle, also affect intended usage. If unsure exactly how to distribute the sealer inside the tire, search the web for videos explaining this critical step.
Most car tire sealers are designed for emergency use and will last long enough to get drivers to the nearest mechanic. Keeping a sealer and air compressor handy in your car to plug a hole can save time spent changing a spare tire.
On the other hand, bike sealers can be used as a shield to help prevent thorns or other sharp items from puncturing tires. Below is a list of different sealers and their specific uses.
Intended as a short-term solution for a slow leak to get you to the nearest gas station, aerosols are not as durable as other sealants. These sealants are highly flammable and also should not be stored in areas that have a temperature of over 120°F. Most have carcinogens and ingredients that deplete the ozone layer and are recommended only for a quick fix to a punctured tire.
Any sealer that comes in liquid form is a liquid sealer. Some common materials used in liquid sealers are latex or rubber, aramid, or kevlar fibers. They are inserted into the tire using an injector and special valves.
This is one of the most commonly used sealers for bike wheels due to its quality and performance.
This sealant is injected into a wheel in liquid form to fill holes and punctures. Once the holes are sealed, the liquid plugs the space between the tire and the rim.
A type of liquid sealer, latex simply refers to the primary material used in the sealant. People who are allergic to rubber should either avoid this type of sealer or use gloves to prevent skin contact.
Secure a hole in a car, truck, or bike tire with one of these tried and true tire sealers.

Instantly seal leaks with this Slime repair quality sealant. One bottle should work as a tire patch for 20 bicycle tires. It can be used on cars or small SUVs for up to 100 miles before needing repair. It also has effectiveness in cold weather. Some customers noted that the included valve core removal tool wasn’t the best, but the sealant itself was excellent value for money.
“This sealed a nail hole in my tire,” explained one shopper. “This is the first time in decades of experience, and through countless flat tires, I have ever seen an over-the-counter tire repair sealant work.”
At the first sign of a puncture or low pressure, this bottle of Stan’s sealer liquid works on contact. Injected into bike tires ahead of time, it works very well for tires that go over sharp objects like rocks or cacti when off-road. Additional features include working on high or low-pressure tires, on the highway, or even in cold weather.
If in doubt about exact tire specs, be sure to check Stan’s website. “Love Stan’s no tubes sealant,” raved one buyer. “I have been using it with my tubeless application for two years with no flats to report.”
Designed for use in cars or smaller SUVs, this TireJect sealer will come in handy in an emergency and can be used for drills that are ¼-inch or smaller. The manufacturer suggests that customers connect the valve stem to the bottom of the tire and gently inject the product into the tire for best results.
All tools needed to remove the tire valve are included with the package. One purchaser described, “TireJect worked fantastic on three cars that [had] leaking tires. After insertion of TireJect into each, [there were] no air leaks whatsoever.”
Intended for emergency use, this spray from Fix-A-Flat works on contact with holes that are less than ¼-inch long. The ecological formula is less toxic than the standard aerosol tire sealants, which is good news for both you and the environment. This sealer lasts up to 100 miles after application.
Be sure to check the company’s website to see which of the four sizes is appropriate for specific car sizes. “It really works,” expressed one consumer. “I keep one in my car and one in my wife’s car at all times. This will get you off the side of the road and to a service station. Super easy to use.”
Suitable for a truck with thicker tires, this liquid rubber TireJect sealer can replace the need to install a spare tire in emergency conditions. Tools included are a dispensing cap, metal valve remover, and stem cap. Use only the recommended amount to cover small beads or tread punctures to ensure the correct pressure.
One happy customer reported, “I knew it worked great in my UTVs, and it worked equally as well in my ½-ton truck tire. One pouch sealed up the leak, and it hasn't budged since, through both hot and cold weather.”
Useful to plug nails or other punctures in tires, this Slime sealant was one of the highest-rated sealers for its ability to seal tires for up to two years.
It even works well on alloys or rust, whether in a hot or cold area that reaches -35°F. If in doubt about how to connect the valve, Youtube has several helpful video instructions.
One shopper who mows over the thorns of water locust trees and has used many other unsuccessful sealers on their mowers, explained, “Since putting this stuff in all my mowing and bush-hog equipment, I have not had to even add air to any of their tires, and that has been two years now.”
Customers who live in areas that experience extreme cold or hot temperatures and drive over rough terrain will appreciate the usefulness of this Truckerco sealer. The cream formula won’t freeze in temperatures of up to 10°F and won’t dry out either.
It can be used for smaller tires such as those on bicycles, UTVs, ATVs, or lawnmowers.
One customer expressed, “The cool thing is that it has a ton of latex in the solution, so when punctures occur, it has quickly sealed what would be considered ride-ending punctures if using other brands.”
Over 96% of Amazon customers loved the performance and endurance of this Orange Seal tubeless sealer. Available in three different sizes, from four to 16 ounces, this rubber-based formula works quickly to plug holes and lasts for 120 days.
Their website has a complete listing of correct dosages for different tire sizes and how to connect valves properly. One cyclist reviewed, “What I like best about Orange Seal is the bond at the bead which is so solid, it makes re-inflation simple. I find that invaluable on the trail.”
This Berryman sealer is top-notch for pneumatic tires and tubes that regularly ride over rough terrain full of sharp objects.
Even in extreme weather conditions, it remains liquid and works on even sensitive aluminum wheels.
Simply connect the included pump to the tire and pour the liquid slowly into the tube. One reviewer who had a steady leak on their ATV used this and, six months later, wrote, “Amazing! I still have not had to put air in tires that I sealed with this.”
The performance of this kevlar enforced formula from FlatOut is highly rated and easy to use, even for larger holes. It can seal punctures up to ½-inch wide and should only be used for off-road applications. It is suitable for smaller vehicles like bikes, ATV/UTVs, dirt bikes, riding lawn mowers, golf carts, and boat trailers, and not for cars or trucks.
Able to work in temperatures of -30°F and over 104°F, this is a versatile and robust rubber-free sealer.
One reviewer commented, “This stuff seals up some pretty large holes and stops slow leaks instantly. Better than tire liners, better than the ‘other’ slimy stuff, and maybe even better than the super-expensive tire ‘armor’ products.”
Slime’s non-toxic tire sealer (US$8.97, Amazon) received consistently high reviews for cars or small trucks and works well in emergencies. For bikes, ATVs, or other off-road only applications, the kevlar enforced FlatOut tire sealer that is also rubber-free was the most versatile in extreme temperatures and is incredibly long-lasting (US$14.97, Amazon).

Anti-puncture sealants are quite densely settled in the trunks of motorists.
Their convenience is that in a matter of minutes this liquid from a can can solve a huge problem - to repair a puncture in a wheel without dismantling. But is “anti-puncture” so universal? The AutoView portal found out when magic does not help, and can even harm. nine0009
Efim Rozkin
"Thank you" for the appearance of a liquid for the quick repair of punctured wheels, as in most cases, with all sorts of useful technologies, I must say to the military. First of all, "anti-puncture" was invented to quickly repair the wheels of military equipment in combat conditions, when delay becomes unsafe. The magic liquid is poured into whole tires in advance, where it simply dangles, waiting in the wings. In the event of a breakdown of the wheel, the agent finds the puncture site, and, having fixed on its walls, hardens. In this way, damage up to 6 mm in diameter can be repaired. nine0009
In general, the military could not contain their joy, and, as in the case of WiFi, Bluetooth and other once-secret technologies, they shared an “anti-puncture” with civilians.
And now it is one of the most popular means of quickly repairing wounded tires. It got to the point that some automakers, in order to save money, began to equip their cars with an anti-puncture spray, instead of putting at least a “stowaway” in the trunk.
So, let's summarize: “anti-puncture” is a means of preventive protection. However, today there are liquids that can be filled not in advance, but immediately after the breakdown of the wheel. These are universal compositions from a series of two in one. But, be that as it may, they have the same goals and principle of operation - to effectively repair a punctured wheel. And here it is important to understand when the use of such liquids is justified, and when it can be harmful. nine0009
Photo from open sources
First, you need to understand that an excess of such sealant will introduce an imbalance in the wheel. There will be vibrations, hum. The lack of liquid will not bring any benefit or harm. You need to pour exactly as much as recommended by the manufacturer.
Then pump up the punctured wheel, and drive a couple of kilometers at speeds up to 80 km / h so that the sealant is evenly distributed over the inside of the wheel, detects a puncture and seals it. And here motorists make the second mistake. nine0009
It must be remembered that “anti-puncture” is a temporary measure. In other words, such sealants are designed for a short period of work, so that you have enough time to get to the nearest tire shop and carry out a full tire repair. Otherwise, the plug formed by the sealant will let you down at the most inopportune moment. And the consequences can be fatal. Therefore, after using the “anti-puncture”, you should visit the tire center as soon as possible, where it is necessary to clean the inner surface of the wheel from sealant residues, and repair the hole using traditional tire repair technologies. nine0009
It is also worth remembering that the anti-puncture sealant perfectly copes with wheel holes on the working surface - on the tire sole.
But it does not work at all with side breakdowns, and even more so with cuts.
It is best to carry a repair kit with a harness. This repair method is much more reliable, and takes about the same amount of time. Yes, and such a kit costs a mere penny.

4. Plug the compressor power plug into a DC12V accessory power outlet or vehicle cigarette lighter. nine0083 5. To avoid battery discharge, we recommend starting the engine.
6. Set the compressor switch to position "I". The tire will fill with sealant. Hold the sealant bottle upside down.
7. If the sealant in the tank runs out, the compressor pressure gauge shows a pressure of less than 6 bar for a short time (about 30 seconds). Then the pressure starts to drop.
8. This means that all the sealant has been pumped into the tire. The tire must then be inflated with air. nine0083 9. The operating pressure in the tire will be established after about 10 minutes. After reaching the desired pressure, turn off the compressor.
10. Continue driving immediately to allow the sealant to spread evenly over the tire.
