20 Best Lawn Mower Tire Sealant (2023 Updated)

I’ve been using TireJect for several years and that’s why I put it in my new John Deere riding lawnmower. It is simple to use. I suggest using some nitrile gloves should you get some on you like I did.

So simple, remove the core from the valve stem with the core remover. Install the amount of TireJect you want per tire. Reinstall the valve core back in the stem. Air up the tires and then I take the mower for a spin to get a coat on the inside of the tires.

I’ll drive in tight circles to slosh the mixture all around in the tires. I do the two front tires and then the two rear tires. Doesn’t take long at at. Great stuff. I originally started using TireJect because I had two tires leaking at the beads.

Fixed it completely in about 10 minutes.

This is my second gallon of tireject. I put most of my first gallon in a large tire with a slow bead leak and I think it fixed that one. I put some in small mower deck tires and it’s helped a lot. But haven’t had good luck with 4 wheeler tires.

The first one I was disappointed with was a plug in the sidewall of a tire that leaked. It would keep leaking, and I did add extra tireject because I wasn’t sure how much it had lost. I didn’t see much come out, just a little.

The second one that didn’t work was on a 4 wheeler tire with a small hole that it didn’t seal. It leaked slowly so took air out and put tireject in and ran it that way. Today I noticed the tire extremely low on air and put air in it.

This hole was in the tread area and when I put it down tireject does come out. I will put a plug in.

I had slow leaks on tires on my Sears 42 inch riding lawnmower. They go flat in about a week. Soapy water on the small front tire shows bubbles from invisible cracks. The rear tire has a hairline scrape on the side where I must have scraped against something.

It also goes flat in about a week. Both innertubes would have cost about $30 but would have required me to remove the tires. So I spent almost $50 for this stuff. According to direction and tire size, I should have needed 5 oz.

in the front tire and 10 oz. in the rear tire. I did exactly what the directions said and was surprised and disappointed that neither flat completely sealed. Still got bubbles with soapy water. So I used the rest of what I bought and put a total of 10 oz in the small front tire, and 20 oz in the larger rear tire.

Neither tire completely stopped leaking. I put the tires on their sides with leak at the most dependent portion of the tire. Still no improvement. I hear the stuff slosh around inside. Overall there is about a 40% improvement so the tires now go flat in about 12 days instead of 7.

Next time, I will simply buy the cheaper inner tubes and go to the bother of removing the tires from the wheels. I would not recommend this product despite what is seen on youtube. Both tire leaks were well within what this company claimed would be stopped.

This is a great product for use around the home! One of the features I like is that it cleans up with water because I usually make a mess with anything that is liquid. I used it to seal the pneumatic tires on the dolly at the place where I work.

The tires were always losing air. Now, this is no longer a problem! I also like the visual and the printed instructions. They are very easy to follow and understand making use of the sealant a snap. Related to the ease of understanding the instructions, I like the 4oz.

and 8oz. marks on the 16 oz. plastic container which make measurement easy for the appropriate quantities that need to be added per tire. Note: This sealant is not packaged in an aerosol can so it will not inflate a flat tire at the same time it is injected.

In fact, to inject it into the tire it is necessary to deflate the tire first and then reinflate the tire once the sealant is injected.

We just moved into a new construction home and have construction going around us. So it’s normal for us to see nails and screws on the asphalt. So when my sons bike tire had a hole in it I knew where it came from.

This sealant worked so fast and so quickly my son didn’t even have enough time to cry because he was missing out on riding. I’m honestly blown away. It’s very thick and the bright green color is so easy to see so you can see where it goes.

I just put some in his tire and it instantly plugged the hole. I will replace the tire eventually, but at least he’ll be able to ride his bike. The quality and packaging is great! I love the tube and that it’s clear! I can see exactly how much product is left and I can squeeze it in.

It worked so well that my neighbors have all purchased some for their bikes and golf carts. This really works!.

I heard good things about it and i used it when i had a slow leak in my 24 x 4″ fat tire bike tube. It stopped the slow leak instantly. However, i later rode over some glass and my tire was bald and i got about four regular flats as the wheel rolled over the glass, and my tire deflated in about thirty seconds.

As i was riding, i was(waiting to see if the Slime would work). It didn’t work. I had to push my heavy e-bike home. When i got home and removed the tube, all the inside of the tire and around the tube was full of Slime.

Very greasy and messy The holes were not that big, but still, the Slime squirted all over the inside of the tire. Before i could patch the holes with a glue and patch kit, i had to degrease the inner tube.

Now, if i was on the road,. far from anywhere, and this happened, and i relied solely on the Slime, i would be in trouble. In addition, if this happened and i had a patch kit on hand, i would have to bring along some cleaning agent to clean away all the slime because as i applied the patches, Slime was oozing out as i pressed on the patches to hold them in place after gluing.

So, i had to try to squeeze the tube and move as much Slime as possible away from the hole so that when i applied the patch, no Slime would ooze out and interfere with the glue under the patch. What a headache.

The Slime is still not doing the job and when i get a flat now, i have all this extra cleaning job to do just to apply a patch. I won’t buy or use this Slime anymore. I wish i could get it out of my tube.

Since then, one of the patches sprung a leak and again the tire went flat, and again Slime was everywhere. Same cleaning job, again. I think i have to buy a new inner tube. I’ve been “SLIMED”! (think of Ghostbusters).

Sealed up all the holes we got in our ATV tire from thorns! I bought this slime as well as a patch kit. On an ice fishing trip we got a flat tire on our ATV. I patched 2 noticeable holes with the patch kit and didn’t hear any more air leaking out of the tire.

The next morning it was still flat again though so I used the slime. It worked great! Sealed it right up for the rest of the weekend. Id recommend buying this and just having it on your in case of emergencys.

Very nice people to talk to and I’m optimistic the product will prove itself over time to be good value but right now I give it a score of “average”. Should have tested it first before taking their word that it cleans up with water.

It does. but on porous concrete it will take a heavy nylon or steel brush and some serious elbow grease. I’ll do the next 32 tires in the grass. Bought 3 gallons to do every tire I’ve got – so far have only used it on 28 of 60 tires but the results are a little underwhelming.

Bought for a miscellany of tires around the farm – farm truck, golf cart, multiple trailers, hand truck, pull carts, mower, tractor and therefore based upon the age, condition (dry rot, prior patches and plugs) I foresaw a variety of results.

So far nothing has held close to 100% of the pressure when aired up the first time and I’m now a couple of days in and I’m topping up tires for the 2nd time. Hopefully they all hold now. It can be a messy job pouring from the gallon jugs and the measuring markings could be a little easier to see and/or marked on both sides of the syringe.

Some tips that are either not clearly specified in the instructions or not at all: (1) The best way to do a lot of vehicles is with a floor jack since you want the valves at the bottom when injecting the tires and with the valve @ 6:00 it is easier to pinch off the clear tubing by holding the syringe so the tubing squeezes shut in a “V” when you push the tubing down and the syringe towards the tire.

Otherwise, without a jack you will have to move the vehicle to get each valve positioned correctly. Once you’ve removed the core, install the black adapter tightly to the valve stem but at this point don’t attach it to the clear tubing/syringe.

Now attach the tubing to the black adapter and turn the syringe’s measuring index (by spinning the tubing where it attaches to the adapter) to face you before you begin pouring. Be sure you have pinched off the line before you start.

There may be some residual pressure in the tire created by you squeezing the syringe and it may prevent the last little bit from getting out of the syringe and this is where it can get messy. (2) Another reason for using a jack or at least supporting the wheel (if you are not removing them completely) is to prevent the bead from breaking or doing damage to an older tire before you can fill it and air it back up.

(3) After doing a few tires you may want to stop and wash the syringe and adapter. They will quickly get a build up that makes them much harder to clean later. I don’t have hot water in my shop and hot water may help in the clean up.

(4) Shaking the product to get the particles in suspension creates air bubbles and if you don’t wait until the bubbles settle out in the syringe you may end up under filling your tires. (5) I was worried that after doing a lot of tires the pressure from the constant syringe use might affect the clear tubing and cause it to leak under pressure and sure enough, after more than 20 tires on a hot Florida day, the syringe pressure did cause the sealant to leak out a little from the attachment point at the adapter.

I cut off 1″ of tubing and re-attached it. If you are only doing 1 or 2 tires you may not run into any of these issues.

Have had flats in my lawn tractors at my 3. 5 ac. Property in Tucson frequently due to mesquite and other desert thorns puncturing the soft compound tires. Used to take them for free fixes at local furriers we did hundreds of dollars of business with each year but they changed management and policy and said all fixes would cost$25 a pop.

We ended business with them and going back to our dealerships for service. But I had to find reliable way to keep my tires up. TireJect has done the trick. Slow leaks had to be reinflated every morning-no more.

I bought the gallon size since it was such a better value than buying a couple of the smaller sizes. I had 5 bikes to slime. The regular schrader valves were easy to fill. Everything you need (valve remover, hose) is included.

The problems began when I tried to slime the tubes with presta valves (Cannondale). I found a YouTube video showing how to do this. I would suggest you watch a video to see if you would be comfortable with this before buying the product (involves forcing the little nut off of the valve and allowing the valve to drop into the tube).

Other than that I am happy thinking that now when we go on family bike rides the likelihood of getting stopped by a flat is nil. I hope my expectations are right but have not testing the product yet buy running over anything that would have normally caused a flat.

I have a two wheel dolly which the inflatable tires are more expensive to replace, than the entire dolly. I am presently doing construction in an elementary school. THUMB TACKS ARE EVERYWHERE! My tube found one which suspended my material move for the day.

I purchased Slime Tube Sealant with some doubt. I was wrong. I slimed the inner tube, added air and spun the tire. When I removed the tack, a little green dot appeared without any air escaping. This product saved me a lot of time and money.

I also slimed the other tube as prevention. AWSOME PRODUCT!!!!!!!.

Slime itself works great at plugging leaks. My low rating is for the pump on the gallon bottle. The label on it says 1 oz per pump. After going by this for a while with hit and miss results, I came to find it’s only pumping 1/3 of an ounce.

Explains a lot of problems. Test your pump before hand with some water. If it’s really 1oz, 8 pumps will fill 1 cup. Slime seems to be water soluable.

I’ve tried quite a few different sealants over the last several years, and after a couple thousand miles, I’ve concluded Orange Seal Regular is the best overall seal on the market. How well? Since putting it in my tires eight months ago, riding hundreds of miles over varying terrain, in a few different regions of the country, I haven’t had a single flat.

Granted, some of that is due to quality tire casing, and I’m not a super endurance rider going hard 100 miles a week, or endlessly bombing rock gardens. But as I look closely at the tire, I’ve had dozens and dozens of tiny punctures, and a few small punctures, that the sealant simply, quickly, efficiently and completely sealed.

Orange says this Regular is capable of sealing punctures up to 1/4-inch as well as slices up to 3/4-inch. I think my biggest puncture is maybe half of that, and the sealant worked so well I may have lost as little as 1psi.

This may be due to my riding style (old school XC guy), but I have ridden over my share of rocks in New England, Arizona. Here’s another key. Orange says the Regular has an average sealant life of 30-45 days.

Then, you need to at least top it off, if not pull the tire, get rid of the old seal, and put new sealant in. The very experienced mechanic that sold me on this said that was too conservative, and it lasted longer.

As a test I thought I’d try to just ride until I got a true, complete flat. Well, about 200 days later, I still haven’t crossed that threshold. A good 5+ times longer than Orange says it will hold up.

I wouldn’t recommend this for everyone, but my point is it holds up very well, and you can likely last a few hundred miles over a couple months before it truly needs to be topped off of changed. Impressive stuff!.

I’ve been riding on Orange Seal Endurance for about a year now. My favorite thing about this sealant so far is this: when I replaced my old tubeless tires last month for a new set of tubeless tires, instead of dumping out the old Orange Seal Endurance and throwing it away, I just scooped the old sealant out of the old tires, poured it into the new tires, added a little more to get it to the right depth, pumped them up, and they were good to go.

I’ve been riding them since without any problems. Endurance Orange is re-bicycle-able.

The sealant works well, and the endurance version lasts longer then the original formula. The injector cap with the hose makes setup super easy. I usually keep one or two small injector bottles on hand for setup, and buy the large bottles when I need to refresh my supply.

With 4 riders in the house, I go through plenty of this stuff. One nice thing is if you have to pull off and store a tire, the sealant is pretty easy to peel off the inside of the tire.

Outstanding safety measure everyone should get for any tire that holds air, be it a tubed or tubeless tire, I bought a bunch of bottles of the product called “slime” just to find out that this product is so much better! I am just pleased that I found this product before I used the Slime stuff.

If you own an electric bike and do not have this stuff installed then I, Highly, suggest you buy and carry a few tubes or patch kits as well as the tools needed do repairs, or you can just buy a bottle of this Flatout and place half the bottle in each tire, and watch how your life gets so much better.

This Product will save you a lot! I also am using it for my ,fast, Scooter (electric) as well as my lawn tractor. Get it you will not regret it.

Okay I’m going to keep this real. I believe it’s a really good product BUT, I am not able to use it the way I thought I could. Multiple times my smaller front zero turn wheel ketp going flat about every 3 months.

Anyway the tire guys were saying, the problem is with the tire bead losing air around the rim and this stuff would be useless to fix that. They put a glue on it and I hope it fixes it.

Been taking long ebike rides since buying my bike. Had a slow leak in the rear tire recently and limped the bike home. Found a smal staple had penetrated the tire. Found this product on YouTube and like the results people were having.

Stan’s is fantastic! I use the sealant in my MTB inner tubes, not tubeless. I live in an area with “goat heads” I was getting flats on every ride, then I put Stan’s in my 29ers x 2. 35 (40-50 mL). No flats since! I add about 5-10 mL every 3 months.

After 18 months no flats still on the same inner tubes and I rarely add air to my wheels. Great product if you are prone to getting thorn punctures. When you consider the cost of a flat (lost trail time), patches, and inner tubes, Stan’s ends up being pennies per mile and less frustration.

Definitely worth the cost of a 1 L bottle.

Excellent product that really works. Unfortunately had a bad puncture whilst out on a long ride. Rotated the puncture to the bottom of the wheel and it sealed itself in seconds. Added a bit of air and continued my journey for a further 30 miles.

Have not had to do any further work on the tyre, apart from adding a bit more sealant when I got home. No problems since. I’m really impressed with the product matching the hype, now converting my wife’s bike to tubeless and will definitely be using the Stans kit , also a great product and easy to fit.

Bought the Stan’s No Tubes to set up my Boardman Adv 9. 0 tubeless, which came with the tubeless ready tyres, valves and tapped rims. I bought the Stan’s injector to complete the tubeless setup thought the valve rather pour direct into the true when mounting, so I have ready for tubeless setup maintenance top up in a few months time.

Using the product was simple and I added 3oz to each 38c Panaracer GK tyres after seating through the valve, with a little soapy water on the tyre wall the tyres inflated no problem with a track pump with no visable signs of leaks, after ensuring the sealant was distributed on the inside of the tyre, job done in 30mins and it was the first time I have set up tyres tubeless.

Checking the tyre the next day, it showed no issues and the pressure in the tyres was fine, riding the bike I could the wheels seemingly feeling lighter with no tubes and rotating with more ease. Overall I am happy and it was easier than expected to complete a tubeless set with the Stan’s No Tubes sealant.

British Cycling Discount also made the purchase price even sweeter.

I think this is a real emporer and his new clothes type thing. !. it doesn’t work anywhere near as good as latex. B. it dries out, It’s like growing plants you have to keepit hydrated all the time. C?!? It does not work.

I am not a huge Stans Man, but Stans does work most of the time where this sealant has more name checks than a holiday village DJ. IT DOES NOT WORK!.

In my opinion this is the worst sealant I’ve tried so far. It can’t handle a tiny hole without losing pressure almost completely. Maybe because it happened in rainy conditions and they’re claiming that this sealant can be washed out easily just with water, but if the tyre sealant can’t seal a tiny hole (less than 1mm) and pressure is dropping from 5.

5 bar to 1bar than sorry. It is a fail for me. I’ve used different sealants like Stan’s no tubes, orange seal, schwalbe doc blue, giant and mavic sealants. All of them were better, and my number 1 is orange seal.

That staff seals everything without losing pressure at all. Finish line sealant is cleaner to work with, it won’t dry out and is easy to clean, but cannot do the most important thing. Sealing punctures without losing pressure.

I used Stan’s for many years back when I rode every chance I could. As long as you were going thru tires and fiddling with your bike it was okay for tubeless and puncture flats. It always dries out and leaves a mess inside the tire and is annoying to wonder if you should add more.

I decided to build up an Ebike and didn’t want to use Stan’s again so I researched to see if there was anything better on the market. This stuff is perfect in every way. I still had a half bottle of Stan’s left, but didn’t want to use it on a new build.

I never have to wonder if it’s dried out and no longer able to prevent a flat. You won’t regret buying this tire sealant over your current brand.

A few years ago I had a lawn mower that always had a flat rear tire every time I wanted to mow my lawn. A buddy of mine told me about Slime so I decided to give it a try. It worked like a charm. All you have to do is follow the simple instructions and it works.

The cap on the Slime container has a valve core remover. Here’s all you have to do. Remove the valve core, squeeze the Slime into the tire, replace the core, pump the tire up and ride for a few minutes to let Slime do its thing.

It could not be easier. This year I have a different rear tire that is flat every time I want to use my mower. I got another bottle of Slime and just like before it worked. Very easy fix and it does last.

I put the Slime in my tire five days ago and the tire is fully inflated today. Slime still works. The pictures show how Slime works.

The product seems to work well. But for me it was a bit hard to put in the tire. However I am used to other products that basically apply themselves into the tire using the propellant built into the can.

As a woman with a limited range of motion in my hands this isn’t a product I would purchase to apply myself. My son on the other hand found it to be very easy to apply and commented on it not having a horrible chemical smell like some others do.

All in all my family stated that they, husband, son, and daughter, would buy it and gave it a thumbs up with 5 star rating! That’s an excellent rating from my family!.

I’ve tried them all… Stan’s, Peaty’s, Muc off, finish line, E13, etc. Orange has great sealing properties, doesn’t dry out that quickly, cleans up easily and is ammonia free so it won’t corrode spokes and nipples over time.

What’s not to like?.

The best I’ve used. Has sealed on first try in many settings – used gravel tires going onto new rims. Brand new rim and tire combos in mountain bike and plus bike applications. Just. seems to work. Applicator bottle is easy af to use.

Orange is the best sealant I have used. I used Stans for years and even did some mixed batches of Stans and Slime, because Stans just wasnt doing the job. Then Orange came out and this stuff is amazing! Outlasts and outperforms Stans! I have been using Orange for a couple years now and it has never let me down.

It is the best!.

I’ve been using Stan’s sealant for 4 years and it works great for small diameter punctures from goatheads and cacti. Mesquite thorns usually still require a piece of rubber or bacon. I haven’t compared Stan’s to any other sealant.

Only flat in 4 years is from sealant drying out and a sidewall gash. Tubeless is far superior to using even thorn-resistant tubes.

Used these with my new WTB tires, never could get the tire to seal and hold air. Don’t use this unless you want a part time job as and air compressor. Replace Stans with Orange sealant and problem resolved.

Just the unused bottle in my truck to return it and even the container leaked with the cap screwed tight.

Works great. Did a test with an old tire: pinching a hole with a needle was closed within 30 seconds. Pinching a hole with a nail 3 mm closed within 2 minutes, leaving 3 bar left. Had a flat tire once that did not close.

Reason was a big piece of glass that was still present in the tire. After removing it, riding along and pumping 6 times, it closed in the end with the little bit of sealant that was left in the tire.
