FlatOut Tire Sealant (Sportsman Formula): Perfect for ATVs, UTVs/Side-by-Sides, Golf Carts, and Dirt Bikes

Beth: I had a leak in my zero-turn tire and was constantly adding air. This was easy to use and the tire hasn’t lost any pressure for the rest of the mowing season.

Noshin Rahman: I got a flat tire on my e scooter. The puncture must've been really small because I couldn't see the hole on the tire, and the inner tube would still hold air for a few KMs. I decided to use FlatOut to see if it could fix whatever hole there was.

There are plenty of installation videos online that show how to use it, and it's pretty straight forward. It already comes with the valve stem remover tool, so you don't need to spend extra for the option that comes with a separate tool like I did (unless your valve stem is a different size). Anywho, after filling it up (a bit too much - it was seeping out) I spun it for a couple of times and filled it with air, and behold, no more flats!

I've used it for 20km now. Still hasn't lost any air. I did notice the tire being a little heavier, but it's not that big of a deal. I would strongly recommend putting this in your tubes if you ever get a flat. You won't have another one again!!!!!

Orange Park Paul: I haven't used this yet, but I have it when I decide to put it inside the inner tube.
If this is the same sealant the US Army uses, it HAS to be good...!

drybear: This stuff works great - I had previously added some FlatOut to my rear e-Bike tire, and did have a flat, but was able to add air (fortuantely I also carry a portable air pump) and the tire held up. When I got home, and inspected the tire, there was a nice big staple/brad that had pierced my tire, but the tube still held air. I did replace the tube, but added FlatOut again to the new tube for the insurance.

I do like the new bag design, as it makes it much easier to add the stuff to the tire+tube vs trying to squeeze the stiff bottle that FlatOut used to use.

Alfredo Avila: Hasta ahorita todo bien, lo apliqué a las llantas de mi bicicleta eléctrica, y no se me han ponchado y ya tuve alguna circunstancia en donde creí que se poncharía, pues reventé algo con la llanta en el camino, pero todo muy bien

Jay Allison: Old Timers at 75+ years may not be able to change a tire as easily as they did at 55. So why not take precaution and stop flats before they stop you?
I ride an XT-225 dual sport, my Shopper, (with an S rather than a C). While changing the poorly manufactured replacement rear tire, I accidentally pinched holes in two tubes with the tire irons. Good grief, if you like that sort of stuff. Rather than try a third time or give up, I tried FlatOut. No . . . the hole was near the spoke side of the tube, I could tell from looking at the first tube I damaged. I added more FlatOut, WAH LAH. I rode Shopper to the supermarket, rather than my bicycle. The tire lost air on the way home, but I made it without having to get off.
Another day I played around an hour or so with spinning the tire to lower the holes after adding more air. It held air again. I added air a few times during the next month, and it has held air for about a year now without needing to add more. So, I bought another gallon of FlatOut for the next time I get a 4 tire vehicle registered. I recommended it to a neighbor, so he knows how to stop the two rear tires on his light truck from going flat every month, but he...

Bam~Bam: Bought this for a flat rear tire on my zero-turn, tire replacement seemed pretty expensive. It was easy to use, there’s instruction videos on YouTube for you to watch. The stem removal tool is great, it even comes with an extra stem. I think why it worked so well for me was, I installed-it and proceeded to cut my lawn and my neighbors yard too. This gave it plenty of time for it to do what it does I guess. I think if you just install-it and put whatever wheeled item you use it on back right away, it won’t work properly. That’s just my opinion, take-it or leave-it…

Kevin George Miller: Used about 1/3rd of the bottle one 20" 3.3 fat tire for an ebike. Test rode it. Everything seemed fine. Next day tire pressure was down big. APPLIED IT IN SEMI COLD WEATHER -7°C. So that might be the issue with the sealant being to thick and cold to properly coat the inner tube.

(UPDATE: After running my ebike upside down on a low speed for about a few hrs, in the tire I put the flat out in; it now has seemed to work. Have to make sure you properly rotate the tires that you fill with the flat out sealant and try not to do in cold temperatures.

WARNING !!!! DO NOT pull the clear plastic tube out without bracing the plastic piece it's coming out of. The plastic piece pulled out and came out of place and the tire sealant gushed out a bit. Had to hold in place while squeezing liquid into the tire which is super cumbersome. Also the valve removal tool comes in the lid on the bottle no need for the extra metal one that didn't even fit my fat bike tire 20" rim.
