Design features

In fact, it will also not damage the environment as its made with a biodegradable formula. Once drivers want to remove it from their tires, they can do so with water and a hose.

Convenient features

Using the sealant is straightforward and it doesn’t require following too many steps which would already limit what drivers can do with punctures out on the road. As with most sealants, the valve should be positioned in the upper region of the wheel, so that the formula would evenly coat the wheel downwards. The cap from the spout is inserted into the valve. Before pushing the sealant into the tire, it is recommended to fully extend the fill tube to allow an even flow. Once the filler has been squeezed into the tire, any excess mixture is wiped with a cloth. Once these steps are followed, drivers can re-inflate the tire as they would in normal circumstances.

The result of all of these steps is that the fluid actually seals all punctures. It can be left on the wheel for up to a few days although some drivers report it is in the wheel even for longer. Since the liquid can be in the tire for longer periods of time, it is important to know that it will not corrode the rubber, leaving it intact.

With a manufacturing history of almost 100 years, Berryman has VOC-licensed the sealant in all 50 states. Since it is safe to use under all conditions, it can also be transferred from the car’s tires to any other tires facing punctures, such as those on kids’ bikes.

Design features

Fixing any puncture is easy. First of all, drivers need to ensure the wheels are in the correct position. The manufacturer recommends moving the valve at the 6 o’clock position. Before applying the sealant, it should be shaken for up to 30 seconds for even distribution. Shaking the can while the hose is attached is not recommended. Drivers can then proceed to connect the hose to the tire’s valve. Pushing the activator will release the product. Drivers then release the button when the mixture is not moving through the hose. When the rim is off the ground, drivers can continue their journey.

But Fix-A-Flat also recommends drivers to drive at a slower speed for up to 4 miles to allow the product to evenly coat the wheel. When it has properly spread, the car can be on its way. The manufacturer also states that adding air to the wheel can also be needed to make it reach its normal running parameters. However, leaving the mixture in the wheel is not advisable. All drivers should actually take care of the wheel and take it into a professional within 3 days. If this is not possible, the car should not travel more than 100 miles with the mixture inside the wheel.

Made with a safe formulation, the mixture will not damage the tires or the rims of the car. It is made with a safe formulation which does not impact the environment. Drivers can rely on it for the best results with no side effects.

Even punctures which deflate tires in a matter of days can be dealt with by the sealant. In fact, keeping the tires properly inflated will not actually increase fuel consumption as it happens in all situations with air leaks.

Editor’s Rating:

Design features

Packed in a convenient tube, the sealant is among the most interesting options in its class. It manages to offer plenty of support for those seeking to limit damages done by a puncture by actually trapping the air inside the tire.

Its application is straightforward and apart from locking the air at the point of a puncture, it also works with rim and bead leaks. Representing a more viable option when it comes to sealing punctures while on the road, the sealant is recommended for longer tire life. This actually works by limiting the damages done to the tire by driving with a puncture and with low PSI pressure. Doing so can irremediably damage the tire. This is why most drivers need to use the sealant as soon as they detect a puncture.

Convenient features

Offering permanent seal, the tire sealant stands out with its constant air pressure ensured after application. The product doesn’t actually apply directly over the puncture. In some cases, the puncture is not even visible. But in other cases, objects such as screws or nails can still be found in the tire. In this case, drivers are prompted to remove the obstruction before applying the sealant.

The sealant applies through the tire’s valve, offering a direct response from the inside of the tire, actually locking the air inside it. In some cases, air can be released through the valve during the application as well as through the actual puncture.

Can I use a tire sealant myself?

A tire sealant is not complicated to use. Until a professional can attend the tire and its puncture, the driver can apply the sealant with no extra help and no special tools.

My car has expensive tires, is a sealant safe?

The best tire sealants can be used on all types of tires. Winter tire and summer tires are not damaged by tire sealants if these products are made with the right formula.

How long can I drive for after applying a tire sealant?

Driving away with sealant in the tires might come with limited mileage. Most products allow drivers to drive between 100 and 500 miles before the tire would need to be attended by a professional. Tire sealant is mainly made as a temporary solution to a tire puncture.

I have a puncture on the highway, can I drive away after using the tire sealant?

Given that attending a tire on the highway is legal, drivers can still continue their journey with the best sealants as they are actually made for higher speeds with certain formulations.

My tire sealant has no applicator, how can I use it?

If there is no applicator, the tire sealant can still be squeezed in with a small tube or hose, which is often provided by the product’s manufacturer.

Can I use a tire sealant on my kids’ bikes?

Since car tire sealants are generally versatile, they can be used on other vehicles. Used on bikes, they are easy to apply. But the same application process is followed on commercial or agricultural vehicles as well.

How long can I leave the sealant in the tire?

The sealant is in the tire for a maximum of three days or a number of miles with most products. While there are drivers who live it in for longer periods, it is considered a good practice to find the closest tire specialist to deal with the puncture.

Guide to Buying the Best Tire Sealants

Since there are only a handful of reliable tire sealants to consider, drivers might have a hard time deciding on the right action to take. This is why most drivers should actually have the ability to find the right product from the start, as the last thing they need is to find their sealant is not usable when they have a flat tire. The following criteria and advice is a good place to start an informed purchase.

Application procedure

The application procedure is generally similar on most tires. As a general rule, drivers should apply the sealant until the tire is filled or until the container empties. At this point, additional air may need to be blown in to inflate the tires to their normal PSI levels. Furthermore, some tire sealants come with an included inflation kit, where the sealant is replaced as it empties but which allows tires to be inflated when a sealant is inflated.

If the application procedure is somewhat similar, not the same can be said about the type of mixture and how it reacts in time. This is why reading the full instructions is recommended, even if drivers have already used tire sealants before.

Toxicity problems

The problem of toxic car products is an important one. All drivers should strive to purchase non-toxic tire sealants as much as possible. This serves their own health and even the health of their kids as some of these products are often used on family bikes. Luckily, there are a number of manufacturers who offer non-toxic and biodegradable tire sealants.

Suitability for the type of tire

While tire sealants can offer a solution against punctures in most cases, they can also have specific formulations which recommend them for performance in certain situations. For example, a formulation can be suited for driving at higher speeds while another can be suited for driving in off-road conditions. This is why finding a suitable product is recommended. For the average driver, a general sealant can work well.

Adding air to the tire

Adding air to the tires may or may not be recommended. In most cases, drivers can find their own way towards reliable PSI pressure. But most products actually state drivers should consider adding air, especially if a tire deflates completely. Apart from carrying a tire sealant, drivers are recommended to keep an inflation system in their cars at all times as a result.

Adding air to the tire is no different with a tire sealant. The idea is that the sealant stops the air leak and that the tire can get back to its normal PSI range. This range is often printed on the side of the wheel itself, so drivers always know the pressure to strive for. If a tire is not sufficiently inflated, even with the added sealant, it might actually be damaged after a short number of miles.
This is why most tire sealant manufacturers recommend all drivers to inflate the tire sufficiently to lift the rim of the ground as soon as possible in order to avoid permanent damage. In some cases, no inflation is needed, especially with smaller punctures.

Mileage after application

The mileage which is allowed after applying the sealant is generally limited. This limit needs to be abided by as most drivers need to know driving with a sealant can be unsafe after a longer number of miles. There are stories of drivers recalling using tire sealants which forced them to drive at slower speeds, so it is primordial to actually fixe the tire at a specialist above everything else.


The best tire sealants are those which allow users to have their own comfortable experience, especially when having to deal with a puncture, which is never pleasant. This includes characteristics such as having a sealant which acts in seconds, which is easy to apply and which is non-toxic.

Some of the best tire sealants are also made with sustainable formulations. This means that when their job is done, they are actually easily removed with water and disposed of as they are biodegradable. So without impacting the environment, tire sealants can be considered as reliable products for future use. In the conditions in which most new cars come with no spare wheel, these sustainability issues become even more important. An anti-corrosive formulation is also important as drivers have the ability to use the sealant without damaging the tire or other surfaces such as the rims. At the same time, drivers should need no gloves performing the operation as the chosen products should not be harmful to the skin. In most cases, their top formulations are often lab-tested for various certifications.
