    Best Tire Sealant Reviews & Recommendations 2020

    Best Overall

    This tire sealant, made by Multi Seal, 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.


    It does come with a valve stem removal tool, but it is on the flimsy side. You may want to buy a stronger one just in case. Another drawback is if you have larger tires, it suggests using the entire bottle on one tire. So, if you plan on patching up multiple tires, you will need to spend buy in bulk.

    Best Value

    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 ¼ inch in size, 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 on driving at this speeds around this mark. Also, if you use too much on one tire it could lead to rusting inside the rim.

    Honorable Mention

    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. 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 ¼  inch in size. 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.


    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. The plastic tube may also leak formula, so be cautious when using it and try to conserve it.

    Honorable Mention

    This tire sealant is meant for use on your compact car, full-size car, SUV, or minivan. The container is 450 ml or about 15.2 ounces. This sealant uses Active Seal Technology to create a long-lasting seal on your tire. The sealant comes in a container that looks like a tub and then has a bright red hose attached to the top. You connect the hose to the valve on your tire and pump the sealant into your tire.


    What’s nice about this tire sealant is that it’s approved by most of the major OEM manufacturers and is TPMS-safe. This formula is unique and patented. It’s water based, eco-friendly, non-toxic, non-corrosive, and rinses easily, which makes it safe to use anywhere.


    Unfortunately, you may struggle to have the sealant move through the air line. You may also find that the system works in the wrong direction, and the bottom of the container might burst. To make things more confusing, the instructions aren’t very clear, and there’s no troubleshooting guidance.

    Honorable Mention

    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. The sealant is a liquid rubber mixture that contains tire particles and Dupont Kevlar fibers. Every ten 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.


    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.


    Unfortunately, this sealant only works on punctures that are up to ⅜ inch. You may also find it challenging to get the sealant to move through the injector tube. The sealant tends to not last on certain types of tires, such as farm equipment and off-roading vehicles.

    Honorable Mention

    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 ¼ inch in tubeless tires and ⅛ 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.


    Unfortunately, this sealant is meant for motorcycle tires, so it isn’t the best choice for automotive, off-roading, or farm equipment tires. It’s also likely that you’ll need multiple bottles for a single motorcycle, based on the manufacturer’s recommendations.

    Honorable Mention

    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.


    Unfortunately, this sealant has a very strong odor, which requires you to only use it in a well-ventilated area. The brush that’s attached to the underside of the cap is also messy, which means you’ll get black goop everywhere during use.

    Honorable Mention

    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 worries that it will ruin your wheels. It also stays liquid and won’t corrode or cause rust.


    Unfortunately, this tire sealant will ruin your tire sensors, which will render them useless and be an expensive mess to fix. This sealant will also not stop your wheels from getting punctured or immediately seal your tire if it does get punctured, so it isn’t as protective as other sealants on this list.

    Honorable Mention

    This gallon jug of tire sealant is a unique blend of adhesion agents, fibers, and rubber particles. It will work to quickly coat the inside of your tires. This will help fix any current leaks and prevent future leaks from happening. This sealant is meant for use with your ATV, wheelbarrow, off-road vehicle, or any other low-speed tire. It can effectively fill holes that are up to ⅛ inch in size.


    You’ll find that this tire sealant is very durable, which makes it perfect for use on off-roading tires and more extreme driving conditions. The formula is also safe for use around your wheels because it's non-corrosive and won’t cause rust.


    Unfortunately, this is not a tire sealant for use in road vehicles, mainly because they are driven at higher speeds than this sealant is meant to work at. Given this, you may find that a gallon of sealant is way more than you’ll ever need for the low-speed tires you have.

    Honorable Mention

    You can order this tire sealant by the bottle. You can choose from one 16-ounce bottle or order up to 12 bottles at a time. This sealant can be used on bicycle, lawnmower, motorcycle, ATV, trailer, truck, car, motor home, and heavy truck tires. Follow the guide on the bottle to know how much sealant you need for the size of your tire.


    This sealant has a wide variety of applications, which makes it more versatile than other tire sealants on this list. It’s strong enough to seal punctures that are up to ¼ inch in the tread area. You can use this sealant on punctures, flat tires, slow leaks, and leaks in the bead.


    Unfortunately, for many applications, one bottle won’t be enough. This means you’ll want to check the usage requirements before you buy the sealant so that you’ll have enough.

    Benefits of Tire Sealant

    • Keep you on the road. Being prepared with a good tire sealant can keep you on the road longer. You can quickly use the sealant to patch a hole to prevent more air from leaking out.
    • Prevent further damage. Driving on a tire that is losing air due to a puncture can damage it further. Having tire sealant is a quick way to make sure you patch up the hole once the object is removed.
    • Save your time. Having tire sealant can save you time by keeping you out of the shop. It may not be a permanent fix, but using tire sealant to fix a hole or tire puncture can lengthen the amount of time you can drive on your tires. While it isn’t recommended to drive on a tire that has sealant for very long, it gives you more time to decide when is best for you to get to the shop or find a replacement tire.
    • Extend the tire life. As mentioned before, a tire sealant may not be a permanent solution, but using it will extend the amount of time you can use the tire or tires until you have to get a new tire or have access to a spare tire.

    Types of Tire Sealant

    Gel

    A gel type tire sealant is thick and can be more difficult to put in place. These sealants have a slimy substance and typically need other tools or equipment to make sure the tire is properly sealed.

    Aerosol

    Many tire sealants come in an aerosol bottle for a simple application. These tire sealants allow the product to fill holes with pinpoint accuracy. However, the repair they provide may not be as strong.

    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

    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 FlatOut 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.

    Key Features

    Air Compressor

    You can have the best tire sealant on the market, but you will still need a way to fill your tire back up with air. This can be difficult while on the road. To help make sure you don’t drive on a tire with an insufficient amount of air pressure and risk damaging it further, you should consider purchasing an air compressor or pump to act as an inflator. If not, you could always visit a gas station and use the free air pump outside on your car’s tire.

    Other Considerations

    • 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.

    Tips

    • Consider buying an air compressor or 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 a ¼ 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. 

    FAQs

    Q: How long do tire sealants last?

    A: 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?

    A: This varies on the size of the tire you are trying to fill the puncture in. A lawnmower 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?

    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. 

    Final Thoughts

    If you need to quickly patch a puncture in your tire, consider the high-quality power and effectiveness of the Multi Seal Tire Sealant with Kevlar.
