Flat Out Off Road Tire Sealant, Sportsman Formula, Prevents Flat Tires, Fix a Flat Tire, Seals Leaks, Contains Kevlar, 32 Ounce Bag, 4-Pack

The real deal to preventing bicycle flats. Better than Slime. The Gallon-size is excellent value. I add Flat-Out to all my ebikes

Used this on a tire for our Kawasaki Mule. Easy to use and worked great. Tire had a large puncture that a tire repair kit did not fully fix. No more slow leaks!

I've got a big, fat tire electric bike that weighs about 80 pounds unloaded.I Started getting flat tires. Having to walk my bike home 5 miles with a flat is not fun.Fixing a big fat tire flat is a slow and time consuming process.Regular bike levers usually won't do the job. I have to use motorcycle tire spoon levers to fix a flat.Its not something I'd want to do on a hot summer day, or in the middle of a downpour, or with sleet and snow hitting me in the face, my hands freezing barely able to hold the tire levers. Changing a flat on a electric bike, the power cable connector has to be disconnected, zip ties holding the power cable have to be cut, or electrical tape holding the cable in place has to be cut.Doing all this in a rain storm could be a very electrifying experience in a bad way.I started looking for a better way, a better solution to prevent flat tires.After watching several YouTube videos about different solutions.I tried the Tannus Armour foam liner, right away I got a flat with that and I still had to walk five miles home with a flat tire. It made rolling my bike on a flat even more difficult.Once home, I had to cut the tire liner with a pair of scissors, just so I could remove the tire liner and pull out the bad inner tube. The tire liners are expensive, and didn’t work for me.I went back to YouTube, watched more videos on how to prevent flat tires.I stumbled upon some YouTube videos about flatout tire sealant.One of the Youtube videos shows a guy using flatout and then putting nails and drilling holes into his bike tire, and the FlatOut sealed the nail punctures and the drill holes.I was so impressed, I bought a couple gallons of flatout. There are different grades of flatout specific to the kind of tire. They have a grade for motorcycle tires that I use on my fat tire bike and a grade for regular sized bikes that I bought for my other bikes.The flatout really works. I'd go through nails, screws, big staples, and glass, get all kinds of punctures, and the flatout sealant would squirt out the holes and I'd just keep my bike going at a nice and steady speed, and the tire would seal.It's important to keep the bike rolling when you're experiencing a flat. It helps the tires seal properly. If you were just to pull over and stop your bike the sealant wont seal as well. So keep on rolling when you get that flat.Sometimes the sealant will get on the fender or the side of the bike. The sealant is non-toxic and is easy to wipe off.I had nine or ten punctures in the tire before I finally decided to put in a fresh inner tube and more flatout.Since using FlatOut, I haven't had to walk my bike home.I wish I had known about this product years ago.

Bought to use in my two electric scooters/bikes (both have smaller tires, 10" and 12"). Not too difficult to use the product. For the step of removing the valve stem, the included plastic stem remover actually broke on me after the first stem. I ended up making my own by grinding a slot in an extra allen wrench I had.Definitely helps with the natural air loss. One of my bikes would need to have air added every month. Now it's been over 2 months without issue. I did notice my scooter had gone flat. Tire inspection revealed a broken nail. I removed it, put more air in, and its been holding up for about a month, also without issue.Aside from the stem remover, great product. Use as directed, and in the appropriate application, and you'll be good.

I used this in the front tire of my riding mower that I had to pump up every time I used it. It holds air just fine now.

Been using this product for a few years now works great.Had a snag recently thought I would share, maybe help someone else.Have this in my fat tire electric bike, LOTS of goat head/thorns where I live, recently I replaced my worn-out rear tire and new tube I put flat-out in for obvious reasons.After a ride or two I got a goat head in the tire and it went flat, no problem just pull out the thorn, pump it up and all will be good, not so fast.Flat out did not do its job, what I discovered is that it is cold here now and I guess the flat out perhaps does not move as well in the tube. I was about to give up and take out the tube to patch.I put the bike in my warm shop overnight and then in the morning I thought to give flat out another shot, so I again aired up the tire and it worked as Flat out should.No way to know for certain but I think the warm environment (wood stove) softened the flat out so that it could fill the hole.Hope this helps someone.

I read all the great reviews on here and bought this 💩. A few months after putting this in my ebike tires, when I really need it to work because it's my only vehicle, I got a flat. Don't even see anything stuck in the tire, but I could feel air coming out the tire when I aired it back up. You can see slime everywhere from this leaking out but failing to seal the tube. This wasn't a huge puncture; I don't see why it didn't work.
