It is often difficult to elude unforeseen obstacles, especially when driving at high speeds. Most unsuspecting objects are small and blend in well with the pavement, so seeing them and avoiding them can be next to impossible. Screws, nails, broken glass, and sharp rocks are just some examples of items commonly found on the road that can easily puncture your vehicle’s tire, causing it to slowly lose air. 

No longer can you continue on towards your desired destination. Instead, you need to safely pull your vehicle over to the side of the road. Once in a safer area, it would seem like the tire should be a quick fix, but it’s not always as simple as you may think. 

Depending on your automobile, location, and other factors, it is at this point in your journey where you may start to encounter larger obstacles. Much like the smaller unforeseen items, these challenges are ones you also did not anticipate. These include problematic situations like not having a spare tire, being stranded on a deserted highway, or finding out that the mechanic shop is closed. The only logical next step is to call a friend to bring you a new tire or contact a tow truck to take your vehicle away. 

Instead of stressing out trying to figure out a workable solution, you could be putting on a tire sealant and already driving away. Tire sealant is a smart solution that you should keep in the trunk of your vehicle. Next time, be ready for all sizes of obstacles with the very best sealant to help prevent any tire from going completely flat.

Best Tire Sealants: Repair Damaged Tires with Ease

Benefits of Tire Sealant

  • Get back on the road quicker. Preparation is key for all parts of life, and traveling is no exception. No matter where you are going, there may be twists and turns along the way. Overcoming challenges that you may have to face on the open road, can be part of the adventure, yet not always. When your tire starts to lose air due to damage, it is vital to repair it as soon as you can. Tire sealant is a quick and easy way to patch the hole to prevent more air from leaking out, getting you back on the road quicker.
  • Prevent further damage. Tires can be costly, which is why most people avoid replacing them until it is a must. If your tire gets punctured by an object while driving, you will want to prevent the tire from receiving any further damage. When you inspect the tire and pull out the object, the hole must be filled. With a tire sealant, you can quickly patch up the tire to prevent it from losing more air and becoming even more damaged.
  • Save time. Stranded at the side of the road is so much fun, said no one ever. Having to wait for a friend or tow truck to get back on the road can feel like forever. Since nobody likes to waste time, having tire sealant on hand can be a great help. In no time, you can put on the sealant to create a tire patch and quickly get to a tire shop or gas station.
  • Extend the tire life. Although a tire sealant is not a permanent solution, it can help extend the life of your tire. Driving on a punctured tire that is losing air is not only unsafe, but can cause a lot of damage to the tire. It is best to cover the hole with tire sealant before operating the vehicle again. Even for short distances, tire damage is still  possible. Use a tire sealant to ensure you can go from point A to point B without experiencing further problems.

Aerosol Tire Sealant

An aerosol tire sealant is one of only two types. A single-use product, aerosol sealants are 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.

Gel Tire Sealant

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.

Top Brands

Stan’s NoTubes

Stan’s NoTubes started in 2001 in New York by a man named Stan Koziatek. Originally, the company began working on mountain bikes with its tire repair kit, until eventually, it developed tubeless tires. It makes the NoTubes Tire Sealant


Slime was founded in 1989 in California when the first bottles of the product were created in a garage. Its sealants were originally built for mountain bikers, but today span all sorts of vehicles. It makes the Slime Emergency Tire Repair Sealant.

Multi Seal

Since 1981, Multi Seal has focused on creating high-quality tire sealant products. It is based out of Spring, Texas and has made sealants to aid the military, fleets of delivery trucks, and consumer vehicles. One of the top sealants it makes is the Multi Seal Tire Sealant with Kevlar.

Tire Sealant Pricing

  • $10-$20: This price range has bottles and containers starting at 16 ounces that offer more solution for more applications or larger tires. 
  • $20-$60: Here, you can find anything from 64 ounces to one gallon or more for a large supply of tire sealant.

Other Considerations

  • Air compressor. Even if you have the best sealant for your tires, it is not a permanent solution. You still need to fill your tire back up with air, which is why you should have an air compressor. Consider keeping the compressor in the trunk, near the sealant, to ensure you have what you need to get back to driving. If you attempt to drive with an insufficient amount of air pressure (which we recommend you do not do), you run the risk of damaging the tire even further.
  • Frequency of Use: Before buying a particular tire sealant, it is important to consider how frequently you may need to use it. Keep in mind that tire sealant can be used multiple times before running out. This is a good thing to note if you have multiple tires you need to patch or if you plan on resealing the same puncture several times.
  • Bottle Size: If you continue to drive on the punctured tire and you’re unable to reach a mechanic for some time, opting for a larger bottle size or multiple bottles is a good solution. Tire sealants are not a permanent fix and will eventually start leaking again. This means you will use a lot of the sealant and may need more of the compound if you don’t plan on swapping out the tire for a while.
  • Vehicle Type: Not all tire sealants work on every vehicle. Some are specifically designed to seal the rubber on ATVs, dirt bikes, mountain bikes, or lawnmowers. Keep this in mind when you are purchasing a type of tire sealant.

Best Tire Sealant Reviews & Recommendations 2021

This tire sealant works hard to seal and repair puncture wounds in your tires. The addition of the Kevlar modifier enhances the compound, making for a thicker and more protective barrier. It eliminates slow leaks, keeping you on the road longer and saving you time and money by not having to bring it to the shop.

One of the best features we liked about this specific tire sealant is it can be used on punctures up to half an inch. While that may not seem like much, anything larger will have to be fixed by a professional. Multi Seal claims it can prevent up to 95 percent of flats when used as a quick repair on the side of the road. Another great feature is the sealant does not include latex or adhesives, and it is noncorrosive, nontoxic, and nonflammable.

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 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.

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 20-ounce bottle means you can take it with you and quickly use it in case you have a tire emergency.

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, non-corrosive, 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 in the six o’clock angle, which can be difficult to do by yourself.

This tire sealant is meant for use on your compact car, full-size car, SUV, or minivan and is suitable for all vehicle brands. The sealant comes in a 450 milliliter container that is attached to a high performance 12-volt compressor which is powered by your car’s cigarette lighter. This sealant uses Active Seal Technology to create a long-lasting seal on your tire. You simply connect the hose to the valve on your tire and pump the sealant into your tire. 

It’s got an integrated LED light for nighttime operation and for added visibility of yourself to oncoming drivers. The kit also features an ergonomic and comfortable handle for easy carrying. It comes with a carrying and storage bag and additional adapters for balls, inflatable toys, bike tires, and more.

When ordering this tire sealant, you have the option of choosing 10, 20, or 40 ounces. You can also choose to order a 1-gallon container.

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. 

This tire sealant is more of a bead sealer than an actual tire tread sealer. This sealant will help you create an airtight seal around the edge of your tire where it connects to your wheel’s edge. A single container is 32 ounces, which is plenty of sealant for use on several tires. 

You’ll like that this tire sealant comes with an application brush. This means you don’t need anything else to use it. You’ll find that it works well at sealing air leaks that happen along your tire bead. It’s durable enough to use on your off-road tires. When you’re ready to change your tires, just peel the remaining sealant off of your rims after you remove your old tires.

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.

There’s nothing worse than driving along and minding your own business when suddenly, you feel a shift in the car’s handling and start to hear a hissing sound. Straight away, you know that one of your vehicle’s tires has a hole that needs to be fixed. After stopping the vehicle to inspect the tire, you notice the puncture hole is much larger than you thought. If you store Stan’s NoTubes Tire Sealant in the trunk of your car, you will be good to go in no time. This sealant has twice the sealing crystals, and they are much larger than most standard sealants, allowing your large hole to seal quickly. This product comes with 32 ounces of liquid and is safe for the environment.

However, there are some precautions. When pouring the product, make sure it goes directly into the tire. This sealant is not compatible with injector or other valve install methods. Also, to ensure the best performance, inspect the sealant every two weeks.

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 ¼ 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.


  • Consider buying an air compressoror air pump to help prevent a puncture from spreading or getting worse. Tire sealant is effective by itself, but you will need something to put air back in the tires after applying it.
  • Make sure to check with the manufacturer if a specific tire sealant is effective for your vehicle.
  • If the puncture is larger than 1/4-inch, a tire sealant may not be able to fully prevent air from leaking out. You may need to bring it to a professional in this case. 


Q: Is tire sealant permanent?

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.

Q: How long does tubeless sealant last?

Tubeless tire sealant should last an average of 2-6 months. However, the life span depends on several factors, such as temperature, humidity, driving frequency, tire casing thickness, and the number of punctures.

Q: How long do tire sealants last?

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.

Q: How much sealant do I need to use on a tire?

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.

Q: How do I properly use tire sealant?

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. 

Final Thoughts
