What are the best products you've used to put a stop to flat tires?

About 55 years ago, when I was a kid, we would take an old tube and cut it to make our own home made tire liner. Of course, that was not nearly as tough as these expensive tire liners, but back then the modern tire liners were not available. I still use the home made tire liners with Slime in the tube.

For those wondering for a tire less than 3 inches the dosage of flat out is only 8 oz. Their fat tire required 16oz

I think you should have had the wheels on a spindle or a bike and spun them more with the Slime and Flat-out. The way you did it certainly shows Flat-out is a good product but if the Slime had been evenly distributed in the tire it might have done better.

I have Tannus Armour liners on my Warthog fatbike and Tannus instructs to use a smaller tube with them. They also said to inflate to 1/2 of what you would normally use in your tires so if you were normally running 20PSI you would then go down to 10PSI after installing the liners. It also makes sense to use a good quality tire which will also help prevent flats. I like the idea of using FlatOut with the tubes just make sure the tubes you use have removable valves as some Presta valves are not removable ( I learned that the hard way☺).

That was such an informative video. I just purchased an E-Bike 2 days ago and road it the first day and woke up to a flat the next day. Definitely will be investing in "Flat Out". I watched the videos on Amazon and it shows it will fix and actually plug holes up to a 1/2" and last for 10 years in your inner tube. Thank you again for sharing and damaging your tires so we could actually see what would happen. Great Video!!!

I think the 'liquid fixes' would also benefit from the centrifugal force of riding. The continuous spinning of the wheel would force the hole to be filled more quickly and effectively I think.

This video was so timely as your video seem to be. Got a flat on my fat tire bike two weeks ago. Finally, got all the needed tools, supplies and time to repair. I did the old school. Rubber cement and vulcanized rubber patch to fix the leak. Based on your video review, for preventing flat in future, i used tuffy liners (tannus review we so so) and most important flatout sealant. Keep these type videos coming.

You guys didn't even give these a proper test. With the slime and liquids you have to let the tire spin so the liquid/slime is over the hole and will leak out it. Also you need to reflate to 20psi to see will it hold. Also you put a screw into it when the psi was like 0 so the liquid wont work. if you are going to test a screw put it at 20 PSI again and test to see it works

Im SO GLAD you made this video! Im interested in what really works and is a waste of money!

Very impressive! Was considering one one these products, and the liquid ones were always considered messy when the the tube had to come out of the tire for whatever reason. I think this test definitely shows it’s worth it for the money!

I've always used slime in my tires. Where I used to live (montana), goatheads are a real problem. Just the other day I rode to the store, (a half mile each way) and could feel my rear end squirming around. When I got home my rear tire was half flat with a bright gold tack stuck in it. I pulled out the tack and pumped the tire back up to 40 psi (I have 27.5 x 2.40 tires) and after four days I checked the pressure again and it remained at 40 psi. So I'm happy with that. Though I will be switching to Flat out when and if I ever replace the tubes.

I was looking for advice on the best solution for preventing flats on my e-bike. This video was absolutely perfect. Thank you for making my decision a no brainer!

Thanks for performing the test. You did a great consumer reports imitation! The results were clear and the procedure you used was fair. I appreciate the time and effort from both of you to conduct the experiment.

I used Flat Out....this test makes me happy and secure. I have a patch kit for each of my bikes both pedal and e.

You didnt consider a couple critical variables. First, rotation would be spinning the wheel at 10+ mph, not just "a roll" to simulate. And, taking that one more step, the rotation continues after the hole plugs. Some sealers - seal, but then with more use, they let UNseal...and the tire goes flat. You must RIDE the tire, after the hole to know if the sealer holds. If youd have done that, the video would be complete. This oversight does not take away from your channel; I discovered on your channel yesterday that there is a cable/hydrolic break caliper. I didnt know that! I knew the brakes on my ebike were below acceptable. Was going to replace the whole break system, but the kill switch is a thing ive never dealt with before, so i hesitated. Then found your video! What a GREAT idea...to move he capiper down to the breakhead! Who knew? YOU did! Thank you for that insight!

Thank you so much for this video. I got an ebike in May of 2022 and commute with it to work. Since that time I have put on over 3,700 miles and got 4 flat tires all in the rear. Last Saturday I installed the Tannus tire armour and flatout and coming home from work tonight (Tuesday) I knew something was in the tire, but I couldn't tell what it was because it was very dark out. Anyway, when I got back home, I noticed a metal object in the tire. At first I thought it was a staple, but upon closer inspection it's a nail that is bent. I am so elated and thrilled that it stopped the flat. Thank you very much.

I use Slime in my tires and occasionally notice small green spots on the treads and that shows me it works. BTW: 70 lb. Ebike, 200 lb. rider, 26" x 2.30" tires, 100 + miles per week. My point is, it works. As always, thanks for the information Kyle and Ms. Tire killer.

Thank you! I was gonna do the slime, but now I'm going to get the Flatout.

With all due respect when adding fluid you should the valve stem at either 3 or 9 position

decided to use flatout because of this video, got some on amazon right away. For those wondering the mfr says all formulas are the same. It's just marketing on the bottle.

Thank you. You did the exact comparison that I wanted. I ride mostly bike paths and a tiny bit of dirt roads. I'm going with flat out for mine and my sons 20 x 4" ebike tires, period. ❤

Great information! I wasn’t aware of Flat Out, have been using Slime along with puncture resistant tires for a couple of years and it works good against goat heads,

I have been watching your videos for a bit now but this was very helpful and I bought some flat out. You got a new subscriber today

That Young Lady is pretty strong and very helpful!!......Her facial expressions made my day....One always needs a Happy Helper Side Kick!!

I'm 75 doing research on buying an etrike. Your explanation on torque and cadence is perfect and now makes sense. Finally. Thank you. For me, cadence is the right choice. Probably will need the throttle.

This is a video that i have been wanting to see. Thanks for this

Thank you. I'm Flat Out about this review!

Love your shirt! (I"m more of a WWII warbird fan but love aeronautics!)

I'm now rocking the Tannus armor and Flat Out inside Schwalbe Moto X with GreenGuard. There's essentially zero air in the tire, which means I haven't had to pump them up in ~6 months and they feel like the perfect firm ness with my front fork. I'm still reaching close to the top 25 mph speed on flats, so I'd definitely recommend the set up if you want zero maintenance. (That said, when I need to replace them, I might just go with Tannus's totally wireless option which is a bit simpler.) Definitely piece of mind when riding home alone late at night!

thanks for videoing the tests. very helpful!

Great video Kyle thanks for all u do for the e bike community .

I appreciate this video, it rules out the guesswork.

I have used Flat Out for a few years on my riding mower, my property has locus trees on it with massive thorns, I was constantly filling the tires with air. The Flat out instantly solved that problem. I haven't had a issue in the last three years. I believe that the trouble with using the product on a bike or car tire is weight distribution . The product is quite a bit heavier than slime, and could be a balance issue at higher speeds🤔

11 punctures one year later and still holding air. Love this stuff. Take care and stay safe.

Thank you for this excellent service comparison. I will purchase from you because I trust you & want future comparisons.

Great video, thanks for creating and sharing. I will be buying FlatOut tire sealant for my bikes now.

Very helpful! I'm running slime but will definitely pick up Flat Out for the next tubes.

Get video. Glad someone took the time to do this. When I got a fat bike and moved to the country where goat heads are everywhere, by Armadillo tires and Mr. Tuffys no long did the trick. Got nearly a flat a month. 7 months ago I put Tannus liners in. Hurrah! No flats... until I got two 2" nails in a tire. Tannus is great for smaller stuff and glass, but nothing prevents a 2" nail/screw from entering. BTW, I discovered that my Tannus's , which started out over 1/2" thick, compressed to 1/4" over those 7 months. So I"m goin' for the Tannus plus Flat Out. If that doesn't work, I'm switching to wagon wheels.

Haven't run over a drill bit yet, but screws and roofing nails galore. I tell people, just like a car tire, practice changing before you need to. Patching is a good skill to learn- I keep a patch kit and a spare tube in my bag.

Another very helpful video. Thanks to both of you.

Watching from New Zealand....great channel.

I must insist you continue to have your lovely assistant in all your videos. She adds so much to your channel.

Thank you for this video I don't think a lot of people are testing thise stuff online, you might be the only one that took a science approach to it. I just got Mr. Tuffy and hope I can keep nails and screws out of my wheels because that seems to be my number one thing that's punching my tires twice a month. Thank you, you have earned my sub and thumbs up!

Very informative video. Thanks..! I just ordered a bottle of Flat-Out for my new E-bike

Nice demo guys. Now I might add Flat Out to My Tuffy's and be able to run a broken glass road hahaha !!! Thanks much.

Thanks for the informative video. I would suggest supporting bike and weight off the tire you fill with sealant and then re-inflate. The weight of the bike kept the tire bead from seating at the top. Simple solution to keep from having to do it twice.

Looks like a good product. I personally like Stan’s no tube . Well made video. Very informative.

Great info..like the way it was presented

Thanks for sharing your knowledge!! 👍

Love the video! Any idea when the upgraded rad power controllers are going to be in stock?

Incredible test!! Thank you very much....

Got my first flat on my Sur Ron and just ordered this product, they should sponsor you guys, there's even a top Amazon review citing this video!

What a great video 👍 thank you so much I am going to buy some flat out and install it in my tires

That flat-out was impressive! I use Ride-On for my motorcycle and wouldn't ride without it. They also have one for bicycles but I've never used it.

As always, informative and entertaining. Thank you.

Keep up the good work guys. I love your channel, it’s so real. These tests were awesome. I actually pulled a 2 inch screw out of my kenda tire once with the mr tuffy liners. I was able to get home from about a mile but I was pushing it, it was 112 degrees outside so I’m sure anyone understands

Ty for this, very informative i was wondering what to toss in my cyrusher tires an flatout seems legit. You saved me a bunch of 💰

You have a lovely assistant.

Excellent video. Very informative. Well done. Thank you.

excellent review, once again

Great video. I never knew flatout was so good! They also have one that seals faster now called quickstrike i saw after seeing this. Its hard for me though. I sometimes ride in the winter. It takes more air when its cold. And if you store it in a warm area, you have to let some air out or the air expands and could cause damage to the tube.

Thankyou……very informative AND interesting!

Nice video. Great information and your helper makes the videos.

Awesome Vid. Great Info. 👊🏾👊🏾

pretty impressive...thanks for the video!

great job on this!

What a lovely assistant you have. She certainly added some fun to the video!

Excellent test, and I cringed at the wood screws! Ironically, I've never gotten a flat on my e-bike after 3000 miles, but I think that has more to do with the Kenda puncture resistant tires reinforced with ceramic, Kevlar, vibranium or whatever, lol. I've rolled right over broken glass at least a dozen times, and nothing made it through the tire casing. I still put in the Tannus Armour (just in case for group rides), but it should be noted that with a fat tire e-bike, you can't ride the bike because the liner is not enough to prevent the rim from being damaged on pavement. Also noteworthy is that Slime makes it almost impossible to patch any hole the sealant can't handle. Had a friend get stranded on her Super73 when a patch, installed at a professional shop, let go because the Slime attacked the adhesive and caused the patch to fail. The Tuffy Liner helps by being more difficult to penetrate, but you never know when someone is gonna stop you and use a drill on your tire! 😉 A couple more notes about the Tannus Armor is that it does increase rolling resistance a bit, and the more pressure in the tire, the more the liner will be compressed, and the thinner your layer of protection will be. I run mine at 16PSI. They will also abrade the inner casing of the tire due to friction, but it has not been a problem so far. A side benefit though, is that the Tannus Armour improves contact with the riding surface, giving you more control over uneven surfaces.

thank you for doing this!

I took the time to call FlatOut and spoke to the product manager for their Sportsman Formula. They tested it on a name brand of fat tire hunting ebike. I use it as a tubeless sealant as well and it works amazingly well. Much better than either Stans or Orange Seal.

wow - great testing. I see a video where a guy put that liner in his tire, then put the flat out in the inner tube.

Great test, thanks for doing it.

Amazing video im all over this flatout when I get my sur ron

Excellent video. More like that please.

Home Depot "Orbit UPC 2 in. x 50 ft. 20 Mil PVC Pipe Wrap" $5.24 a roll it is thin and fits perfect. Nails, Screws, Thorns glass and more. it's made to protect under ground pipes

Awesome, you have just saved a heap of people a lot of time and money Good for you guys 👍👍

I use Stans Tire Sealant. Its white and works just like slime but not green. I use to fill the leak until I get home to repair it. Alway keep an extra bottle in my backpack. Easy!

Useful and amusing video. I ordered Flat Out right after watching lol.

Thank you for the info. Flat out it will be

I’ll go with flatout, thanks for informative video

This is such a great buyers guide.

I didn't test my tannus armor against a drill bit, but I've extensively tested it against trails and it works great. Riding over a rock garden, you risk holes that are a lot bigger even if the penetration isn't as deep, and they're great for that, even protect sidewall. Also they claim run-flat capability and it's almost true, down to about 3.5 psi.

I'm glad the shirt fits and it is goood looking

Just the info I was looking for.

Great demo!

I think a lesson here is, if you get a screw or nail in your tire, don't remove it until you get home :)

Very cool...thank you for the post.

If I’m not mistaken, I believe you are supposed to go down to a 3” tube when installing the tanis armor

Awesome video and review! Thanks! 👍

Years ago I ran Mr. Tuffy on my road bike, with 115# Clinchers. It worked great, most of the time. After thousands of miles, I flatted twice. Once was a goathead, that worked it's way thru, after a week or so. The other time, I ran over the Head of a nail. It Flipped 180° and punctured my tire thru the sidewall. A definite 'Face Palm' moment.

When I lived in Redding CA, I used armor with slime. Never had an issue

Great video as always! I'm going to be using rhinodillo as the first layer, I will then put in the Tannus liner. I will then add slime to the tube. I will also put putting Velox rim tape on the rim, followed by a PVC inner tube cushion over the rim tape. All items are purchased and on the shelf to be used....as soon as the bike gets here that is. Fedex where you at? :) Will they all fit/work? I'm going to find out!

Great info, thanks!

Your video was very informative and your assistant made it fun, also think the odds of running over anything larger then the size of a roofing nail are pretty small

Skipped this video before but yesterday I got a flat.. so here I am.

THANK YOU! YOU ARE A MONEY SAVER!

I've been a huge fan of Flatout for years.

I use flat out myself after using slime cause flat out claims it seals bigger holes It seems like it works after your test.

You guys are Great.
