My thoughts on The Best ATV Tire Sealant – Dump The Slime

Getting a flat tire in the middle of nowhere can be a really dangerous situation to find yourself in, especially if you’re by yourself or don’t have any reliable communication to call for help.  If you ride enough, you know there are so many different ways to get punctures in your tires and its really only a matter of time before it happens to you.

Quads don’t come with spare tires, which is why it’s a good reason to always have some kind of an emergency kit on you for these types of predicaments.  Even then, there is one extremely important thing you should do to prevent flat tires from ever happening in the first place.

In fact, this works so well that it will last the entire life of your tire and even works on tires that you thought were unusable from dry rot.  It’s a tire sealant for your ATV and the one I recommend most is TireJect Tire Sealant. Keep reading below to get my take on it or you can simply head over to Amazon to see what it is currently selling for.

Who Are The Top 3 Competitors?

#3 Slime

Slime is likely the biggest competitor in this space and probably the most widely available for purchase.  You can find this product in your big box auto supply stores such as Advance Auto Supply or Auto Zone, but in my opinion, you should save yourself the trip.

This green goo is made out of liquid fibers, rubber particles and other sealing agents to create the sealing effect, and yet it’s only able to handle punctures up to ¼” in diameter.  In addition, the amount required to be injected in an ATV tire is up to 32 ounces of product, not only does that slime tend to build up and coat the inside of the tire, but there is concern that it also creates an uneven balance in the tire since the slime can tend to collect in certain areas of the tire.

Imagine how your tires would be thrown off balance if you were somehow able to glue a weight to the inside of your tire in one particular spot, the balance is now thrown off-center, and Slime has the same effect to your tires since there is so much product that has to be applied inside the tire to create the seal.

The company does, however, state that the product is a non-toxic, water soluble mixture that won’t corrode your tires or wheels, but should you ever get a flat then it would only seal the flat for a maximum of 2 years.

As far as the price goes, this product is the cheapest of the three and a gallon of product will run you $35.99.  Considering that you need up to 32 ounces of product, that translates to $9 worth of Slime per tire. Four tires will run you about $36.

Again, think of the amount of Slime that is slopping around in your tire ever time it goes through a full cycle – it’s a lot!

  • Non-toxic
  • Water soluble
  • Cheapest Price
  • Most widely available
  • Only patches holes up to ¼” in diameter
  • Only seals punctures for a maximum of 2 years then the tire needs to be replaced
  • Requires the most amount of product to be injected into your tire
  • Creates 4 unbalanced tires wearing your tires out even quicker
  • Creates build up along tire walls

#2 Quadboss

Quadboss has a tighter distribution channel than Slime does and you likely won’t find it at a local automotive retail shop, instead you’ll have to source it online.  That being said, it doesn’t have as big of a name to it, but Quadboss still offers one of the most popular tire sealant product in the market.

This product claims to seal punctures up to ½” in diameter on the tread and up to ¼” diameter along the tire walls and it will last the entire life of the tire.  It also won’t freeze and won’t stick to tire walls or rims. The owners of the product state it is non-toxic, non-corrosive on aluminum wheels and won’t rust steel and is environmentally benign.  

My issue with this product is that it also takes a large amount of product to coat an entire wheel.  In fact, it takes about 32 ounces of product per tire or almost an entire gallons worth of Quadboss product for all 4 tires combined.  That’s a ton of product and will cause tire balancing issues to a degree.

From a pricing perspective, every 32 ounce bottle of quadboss will run you about $17.99 or if you purchase a gallon of their product, it comes out to $63.99.  It’s close to double the price of the Slime and although the product might be marginally better than Slime, in my opinion it’s not worth double the price. It’s a tough sell for me.

  • Seals punctures up to ½” in diameter on the tread and up to ¼” diameter along the tire walls
  • Seals last the lifetime of the tire
  • Non toxic, non corrosive
  • Tight distribution channel
  • Takes a lot of product to cover one wheel – causes balancing issues
  • Product costs almost twice as much as Slime

#1 Tireject:

From the research I have done, TireJect is the best ATV tire sealant available on the market by a wide margin.

Not only does TireJect seal punctures up to ⅜” in the tread and sidewalls but it uses the air pressure within the tire to push the sealant into the puncture.  This means that as the tire is rotating, the sealant is constantly rotating around the tire wall searching for punctures to cover up and seal.

What’s more impressive is the amount of fluid that is needed to coat each tire.  Whereas both the other competitors needed approximately 32 ounces to coat the same amount of tire, TireJect only needs 8 ounces to do the same work.  

The reason you need such a small amount is because it’s a water soluble product and designed with dupont kevlar fiber and liquid rubber.  In fact, it works so well that it covers all parts of the tire including the rim and bead and even seals tires that currently have tire rot.

It should go without mentioning that the fibers and fillers within the sealant are also going to cover and seal any puncture (within ⅜” on both tread and sidewalls) your tire sees for a two year period.  It’s also not going to rust steel or corrode aluminum so it’s completely safe for use on tires with rims.

When it’s time for new tires, disposing of TireJect is safe and easy since it really just washes off your tires without any scrubbing or scraping.  Just point your hose directly into the tire and it washes right out.

Like anything else in life, there is a tradeoff when you have a great product.  TireJect has limited distribution and can be sourced mainly from Amazon or through their website, though I do prefer the prime shipping.  

Not only that, but TireJect is more expensive than the other two products.  A 10 ounce pouch will run you $19.99 and a 20 ounce pouch will run you about $32.99, but when you consider doing all 4 tires then it actually comes out to about the same price as the Quadboss at $66.

When you actually think about how reasonable that price is compared to having to buy a new tire or even go through the hassle of having to get a plug, i’d rather make the investment into some TireJect and know that my tires are constantly being looked after.

Last, since there is such a little amount of liquid that actually gets injected into each tire, it creates nearly no balancing issues at all and you won’t feel a pull when riding.  You’ll find that 8 ounces is very little when it’s rotating in your tires.

  • Requires very little product – only 8 ounces per tire
  • Does not create a tire balancing issue
  • Made of Dupont Kevlar fiber and liquid rubber
  • Seals punctures for two years
  • Simple injection process
  • Covers punctures up to ⅜” in size on both the tread and the tirewalls
  • Limited distribution
  • Pricing is higher although the price for 4 tires is very comparable to the price of Quadboss

One note worth mentioning on all of these products is that sealants do not fix slices in the tires – no sealant can do that because of the movement within the tire.  If a tire has been sliced, its almost a guaranteed replacement 🙁

How to Install TireJect tire sealant

TireJect is extremely simple to use and won’t require any special tools to insert into your tires.  The only thing I would say is that if you are currently working with a flat, it would be easier to remove the tire so that you could insert the TireJect sealant and then immediately inflate the tire with some air.  It’s easier to spread and distribute the product around when the tire has been removed.

  1. Determine how much TireJect you will need to get the job done.  A standard size ATV will need 8 ounces of TireJect Tire Sealant or one small pouch.  To fill all four tires you would need 2 larger pouches each one being a 20 ounce pouch.
  2. Each application of TireJect comes with a valve core remover so the next step is to use it to remove the valve stem.  Remove it from the pouch and insert it into the valve stem of the tire and turn counter clockwise, just like you would with a screwdriver.  
  3. Next, attach the sealant injector directly to the valve stem.  It will thread directly onto the stem for a nice tight application.
  4. Remove the plunger and pour 8 ounces of the TireJect sealant into the tube.  Just make sure to shake the contents well for the best application.
  5. You’ll notice that most of the contents will flow through the tube on its own, but if you want to make it go through quicker then you can use the plunger for extra assistance.
  6. Once you’ve poured the contents into the tire then you can remove the tube from the valve stem by unthreading it.
  7. Screw in the valve core that was previously removed back into the stem using the valve core remover tool.
  8. Reinflate the tire and make sure to give the tire several full rotations to make sure that the TireJect Tire Seal is making its way around the tire and sealing up and punctures that may exist.
  9. Mount the tire back onto your ATV and make one final check that the tire pressure is where it should be
