Selection Criteria

ATV tire sealant

The ATV tire sealant market is dominated by a handful of companies that have different sealant formulas. In addition, ATV manufacturers like Honda or Polaris produce their in-house tire sealants that are both affordable and highly effective.

Brand recognition was just one of the parameters I utilized while selecting ATV tire sealants for this article. Let’s take a closer look at the selection criteria I used to choose the best ATV tire sealants.

Package Size

A gallon of tire sealant can repair up to four flat tires, but carrying a 1-gallon canister on every ATV ride can be difficult. That’s why I used this parameter to provide you with options that won’t take too much storage space in your vehicle.

Puncture Diameter

ATV tire sealants cannot treat punctures of all sizes, so whether or not a particular product can help you fix a flat ATV tire depends on the extent of the damage. Products featured in this article can treat ¼-inch, 3/8-inch, and ½-inch punctures.

Sealant’s Components

All models I selected for this article are non-flammable, biodegradable, non-corrosive, and water-soluble. I advise against using products that can facilitate the corrosion of aluminum wheels or contain hazardous materials.

What is an ATV Tire Sealant?

ATV Tire Sealant

A tire sealant is a liquid designed to stop an air leak quickly. The product is injected through the tire’s valve system, and it utilizes the air pressure to fill the hole that caused the leak. ATV tire sealants are usually used with ATV tire repair kits that contain the tools you need to fix a flat tire.

It is worth noting that these products aren’t powerful enough to repair blown tires, so you can only use them if the tire damage is relatively small. Also, you cannot use the same tire sealants on the tube and tubeless tires.

Most ATVs have tubeless tires, and you need to check the ATV tire sealant you want to get is suitable for use with this type of tire. These products don’t fix a flat tire permanently, as they’re only a temporary solution until you get your ATV to safety.

ATV Tire Sealant Types

Brands develop unique ATV tire sealant formulas that create a protective coating inside the tire. Hence, the components and the visual appearance of an ATV tire sealant depend on the brand you choose.

An ATV tire sealant can come in the form of spray or gel, but most ATV riders prefer the gel version because it creates a strong bond with a tire, and it is easier to apply.

Aerosol Cans

This type of ATV tire sealant is largely available as you can find it at gas stations and convenience stores. These cans utilize flammable materials to propel the sealant into the tire, and you shouldn’t use them near heat sources. This type of sealant is not water-soluble, which makes it difficult to clean, and it can only be used to treat punctures smaller than ¼-inch.

Gel ATV Tire Sealants

Most gel ATV tire sealants are polymer-based, although some manufacturers add rubber particles to supplement the polymer fibers. These tire sealants are not pressurized, and they don’t contain flammable materials. In addition, they don’t facilitate the corrosion of steel or aluminum wheels, and they can stop an air leak in less than two minutes.

Applying an ATV Tire Sealant

ATV Tire Sealant

Most ATV riders use tire sealants as an emergency solution that helps them avoid replacing a flat tire. These products don’t seal a tire permanently, and relying on them for too long can cause balancing issues.

Adding a sealant to a tire that isn’t damaged won’t accomplish much as sharp objects can still puncture it. That’s why the best time to apply ATV tire sealant is after you detect an air leak. The application process depends on the product, but you’ll have to go through the following steps in most cases.

Connect the Sealant to the Valve Stem

Remove the tire’s valve stem cap and then use the dispensing cap to attach the sealant to the tire. You don’t necessarily have to take the tire off the ATV before adding sealant to it.

Make Sure That the Sealant is Applied Correctly

You should move the tire after applying the sealant to ensure it covers the puncture completely. Sealants usually need several minutes to solidify, so check the product’s recommended waiting time before proceeding to inflate the tire.

It is worth noting that the amount of ATV tire sealant you should add depends on the type and the size of tires you’re using. Go through our to the best ATV gear to learn more about accessories that can make your rides more comfortable.

Repairing ATV Tires After Applying Tire Sealant

Although some brands claim that their ATV tire sealants can last up to ten years, you should take this information with a grain of salt. It is impossible to know if or when a punctured tire will start to leak again, and you should find a more permanent solution as soon as you get a chance.

You should replace a damaged tire to avoid potential accidents while you’re on a trial or place a patch over the punctured portion of the tire. Read our guide to the best GPS for ATV trail riding to find out how to use these accessories to navigate an ATV trail.

The Most Important Factors to Consider While Choosing an ATV Tire Sealant

ATV Tire Sealant

Riding an ATV without having a tire sealant with you can leave you in uncomfortable position miles away from the nearest mechanic who could help you fix a flat tire. These products can buy you enough time to get home safely where you can determine the extent of the damage and search for the best solution.

It is difficult to know how effective an ATV tire sealant is going to be before you apply it, so you need to try several options to find the one that works best for you. I’ve shortlisted several factors that can make your search for an ATV tire sealant simpler, so let’s take a quick look at them.

Sealant Formula

Each brand uses a different formula to create tire sealants for ATVs. Going through the product’s specifications and learning more about the materials it contains will make it easier to understand how effective and durable a tire sealant is.

Most models contain polymer fibers such as Kevlar, and they need around two minutes to seal a hole. Keep in mind that sealants designed for highway tires don’t work well on off-road tires.

Recommended Puncture Diameter

You won’t be able to repair a flat ATV tire if the diameter of the puncture is larger than ½-inch. These products work best on holes created by nails, screws, glass shards, and similar sharp objects with relatively small diameters.

You can also use an ATV tire sealant to repair bead leaks and sidewall punctures caused by sharp rocks or bent rims.

Bottle Size

ATVs don’t offer a lot of storage space, so taking a spare tire or enough sealant to repair all four tires is usually not an option. That’s why you should search for ATV sealants packaged in 32oz, 20oz, or 10oz bottles.

Manufacturers recommend adding up to 32oz of sealant per tire, so 20oz or 10oz bottles may not contain enough sealant to stop the air leakage. However, the exact amount of sealant you’ll need to add to seal a puncture depends on the tire’s size.

Application Method

Avoid ATV tire sealants stored in pressurized cans because they contain noxious materials. Moreover, a single can isn’t enough to repair an ATV tire, and cleaning the sealant is difficult.

Gel ATV tire sealants are added to tires through the valve stem, and they come with a dispensing cap that allows you to connect them to a tire. Polymer-based sealants solidify within minutes, so you won’t have to spend a lot of time waiting for them to seal a hole in a tire.

Durability and Price

ATV tire sealant is a temporary solution that enables you to fix a flat tire quickly, but most manufacturers claim that their products can hold for years. Relying on a sealant to keep your tires from leaking air is unsafe, and you shouldn’t ride too long with a tire that’s been punctured.

A gallon of an ATV tire sealant cost between $50 and $140, while you can purchase a 32oz bottle for approximately $30.

The Advantages of ATV Tire Sealants

Emergency Solution for Flat ATV Tires

Although they’re designed for use on rough terrains, ATV tires are punctured easily. ATV tire sealants allow you to repair a damaged tire quickly so that you don’t have to leave your vehicle unattended in the middle of nowhere.

Simple Application Process

Adding a sealant to an ATV tire is easy, and it takes just a few moments of your time. Moreover, some models are water-soluble, and cleaning them doesn’t require a lot of effort.

Suitable for Large Punctures

ATV tire sealants are powerful enough to seal holes with diameters up to ½-inch. Hence, you can use them to repair punctures caused by rocks or different types of sharp objects you can encounter on an ATV trail.

The Disadvantages of ATV Tire Sealants

ATV Tire Sealant Can Disrupt Tire Balance

Applying 32oz of sealant to an ATV tire will create balancing issues because the sealant accumulates in one segment of the tire and adds weight to it. As a result, you might struggle to keep control of the vehicle, especially at high speeds.
