FLEX SEAL: Can it Fix FLAT Tire? Let’s Find Out!

Can Flex Seal fix a flat tire, trying FLEX SEAL as a Fix a flat, I will drill a hole and fill it with Flex Seal.

[@misterd717]

I can personally attest to *flex tape* patching the inside of a punctured tire. 2 layers worked like a charm. Used bonding cement on the edges of the tape to help keep it secured. Going on a year now, no issues.

[@MotivatedMetalworks]

You know a tire patch would've been about 100x cheaper, and you already said you prepped the tire with cement.

[@sashajohnson812]

And would your tire pressure light ever come on?

[@legendaryscrub]

Tires are vulcanized rubber, so it would make sense that the rubber would be softer. An interesting thought for sure, however I'm not sure even I could cheap out and feel comfortable riding on a tire like that, but I'm glad you tried the proof of concept.

[@GK7GARAGE]

Just an experiment that did not succeed. Thanks

[@junkjunk2493]

thx for your work , this helps us all , bless u too

[@YurtFerguson]

Probably would be a better idea to try it from the inside where the air pressure will work with you.

[@GK7GARAGE]

S0thernman true, maybe next video

[@YurtFerguson]

@@GK7GARAGE I've got a few flex brand products and have wondered about using one for this sort of thing. Perhaps using a circle of flex tape as a patch then spray it down with the seal

This video made absolutely no sense at all to see if Flex Seal could fix a car tire. I had a new set of 4 tires on my 98 Lincoln Navigator ( size 22 Low profile ) and the side of one was split some how after sitting in my garage on a flat over winter. Well, I took it off the rim and cleaned it from the inside as he did with the 70% rubbing alcohol. Sprayed a Few layers of the flexseal in between the split from the inside and then let it sit flat and did it over that. Worked perfect 👍🏾

[@oldschooledgarage9476]

Love this stuff for counter tops!

[@robertknight3354]

[@DeWente69]

It works fine if you pull out whatever made the hole, spray it or put the flex glue on it and the hole, and stick it back in there. Permanent repair.

[@pwolfpapaw8474]

Well, I started watching your video and every finished it today so where I took my tractor tire and put a plug in it. That didn't work so I put fix a flat in it and then sprayed it with Flex Seal so far for coats I'm going to play it tomorrow and see how that works

[@Andres707cristiano]

I think will seal but through the inside bit the outside. But dismount tire and mount back will cost you some bucks .

[@GK7GARAGE]

Yeah true

[@Ferkle871]

It's better to patch it from the inside with glue. Either way an interesting test

[@samlindblom6579]

Should have let it dry longer

[@Covert_Op]

Fill the whole inside of the tire with the can of flex seal from the inside like through the valve.

[@WhiterLiar]

It’s not a fair test to drill a hole in a tire. Most punctures come from nails and screws. They don’t actually create gaps in a tire like drilling does. It just doesn’t seem likely to have such a large hole in a tire.

[@josephmelcher1312]

What would work is if you pop the bead open and use the flex tape as a patch on the inside.

[@tenzackyogi1742]

You should do it from inside. Which will be more effective...

[@wylapache5362]

Either your car is dropped or you have negative camber, that wears out tires faster from the inside towards the frame of the car. I had that happen on my G3 Integra, dropped on all 4s and it ate through all the tires same way as yours.

[@wylapache5362]

If you really wanted to isolate the spray you should have masked off the spray area with masking tape to prevent overspray on the tread

[@eazytazz]

I've only done what I'm explaining on my weather checked atv tire but flex seal will seal a tire my tire deflated overnight so I took it off rim got the flex seal you put on we with a brush and coated the inside of the tire and let dry overnight tired it up and hasn't went flat since

[@jeannettegonzalez7370]

What about for the side wall

[@edwardprice140]

It didn't work because you patched the outside of a pressurized tire. Try it on the inside so the pressure will help the seal. And nobody runs over a spinning drill, try a small nail.

[@annagraham6204]

I thought that was the point of trying to fix without taking tire off. Do you know what a pita that is without a bead breaker. I bet a slow leak could be fixed from the outside.

[@paul07291983]

Was considering for lawnmower tire as the tires for it are $94.95 each at Farm and Fleet

[@user-um4dx5oo6g]

I can't wait I'm stranded now with and told my tire and need to get home

[@thunderquacxstaynchill3834]

You are using it on the wrong side, remove tire and spray inside it works perfectly.

[@user-um4dx5oo6g]

What if you left it alone and didn't wipe off the excess and then you went down the tire a little bit further and maybe even use the flex tape on top of that to see if it would help to seal it I am an emergency so I had to get flex tape brought to me but not the tape I'm getting the spray I hope it works for me to get

[@ShawnaCostonPhD]

Interesting.

[@lukelogan8539]

You should not have so much negative camber on your car and the tire won’t wear like that and you wouldn’t have this problem but thank you so much for the video always wanted to see this be done

[@vansmalley1709]

What was the bit size used for this experiment? That seems like an awfully large hole to expect the Flex Seal to work on, given the pressure put on it after re-inflating. Plus, 24 hrs was probably not long enough time for curing. Directions say, 24-48 hrs...and maximum strength in 7 days. I have SUPER SMALL puncture, on 1 car tire, with NO VISIBLE evidence of the object that's in the tire. It took 2 (looong) visits to repair shop before they finally found it! It was so small they couldn't find it after doing soap/water test AND even after OVER inflating tire...2.5 times its rsted PSI level. The leak is VERY SLOW, losing 6 to 8 PSI in 3-4 days after correct inflation. I'm going to try the Flex Glue & see if it helps slow the leak more or (hopefully) stops it... completely. I will try & do the Flex Tape on inside, too. But may have to remove the object, if it's poking through enough.

[@sanad9193]

It might be the puncture though

[@vansmalley1709]

?? I understand the relevance of your statement. "What", might be the puncture?

[@markmitchezee2728]

Dude... Not even the cheapest tire repair kit just sits on the outside. I think Flex Seal would work Great !But, the correct way to test it would be to put one of those small red straws ( WD - 40 type ) onto the spray nozzle and insert it into the tire a little bit to completely clog the hole. Maybe put it inside so it has a slight build up from the inside similar to an internal patch. Then it would work. No Doubt ! But you have to have the entire hole filled with rubber and connected to a larger blob of Flex Seal sitting on the surface of the inside that is unable to be pushed through by the inevitable pressure. Bevause the main point is to keep this patch from Blowing while on the road under increased stress, pressure & heat. But it will work if done right.

[@cognizantray6069]

U have to use the flex seal caulk super thick version

[@OhioBoii330]

Sooo, u just patched my friends tire that had a screw in it. I used that "Slime Tire Patch and Repair Plug" stuff that has those rubber plugs. It did not come with any rubber cement tho. But, I plugged the tire and it did hold air. But, I was skeptical to put it back on the car because it didn't come with any rubber cement. Soo, I did spray some of this "Flex Seal Liquid Rubber" over the plug. It says to let dry for 24 hours. Soo, I left the donut on her car for now because I didn't wanna put the tire back on and it end up leaking once she drove it. I'm gunna go back tomorrow and see if the Flex Seal Liquid Rubber will act like a rubber cement and keep the plug in the tire without it leaking air, or just completely ripping out of the hole when she drives it. I know all these videos say it doesn't work, but considering I did use a plug and stopped the leak, I'm curious to see if the Flex Seal will work that way.. Does anyone have any experience doing this? Or do you guys think it will work?

[@laserfalcon]

I would think flex seal would work awesome as a inside the tire sealant

[@jordskiiez111]

I can say it does work he just didn't do it very well

[@kevinhofferth6097]

Im going to try multiple layers on my balding trailer tire for extra life see how it goes🩹

[@DJJAZZYREAVES]

It would make more sense to put flex seal inside the tire to have the pressure forcing against the hard service rather than off a hard surface. SMH

[@jeremiahvasuqez6453]

Fr😂

[@randallmarsh446]

you should put the flex seal from the inside of the tire with a small webbed material ilike used for plaster ,fiberglass matting ect. 2 layers would probably b e more than enough.. the air pressure will keep the seal on the flex seal with matting ..

[@randallmarsh446]

i worked out away in extreme remote locations .. the neatest tire sealer i have ever seen was completly out of this norm of my scope of quick fix schemas.. plain old cotton from the plant mixed with a little flour and elmers glue will plug a hole in a farm tractor front tire half inch!! the operator wa s from mexico and he said if you dont have cotton go find a pillow with the feathers will work just as well but u have to throw a couple of wash rags inside the tire first and let them start to plug the hole and just let it sit until the rag dries on the inside then throw the rest of the cocncotion in the tire and air it up past the norm pressure by 20 pnds then spinn the tire till it quits leaking then get to worlkkk! lo it works

[@bryanmckinney5366]

You should take the tire off the rim and use flex tape and try to patch it from the inside to see if that works

[@annagraham6204]

He doesn’t even have an air compressor I doubt he’s got what it would take to break the bead.

[@profdleeucc]

Now you almost had the right idea fundamentally; all one simply has to do is use the rubber flex seal in conjunction with a conventional latex rubber tire plug; simply coat the entire exterior of the latex rubber tire plug with the spray on rubber flex seal; and then insert the freshly coated rubber flex seal tire plug using the hand tire plug insertion tool half way into the tire carcass; then simply let it cure for about twenty hours or so and it should now not be leaking air hopefully.

[@joshuarodriguez8142]

It might be possible if you sprayed it in the inside of the tire 3 to 4 coats

[@GK7GARAGE]

True that may work

[@spitfirelast8761]

Damn i ordered them when you were spraying it onto the tire.

You should plug it from the inside no one could ever expect it to hold from the outside.

Can Car Vacuum Tire Tubeless Tyre Puncture Repair Rubber Screw Nails Kit??try please

[@BarryObaminable]

It would probably work. You are going to get a bunch of "company says not to do this" because of liability lawyers....etc. from the company. why not spray it on the inside? That will work far better. I bet you could take a piece of screen from damaged window and spray it. I wouldnt expect it to balance at 65 mph. but you could probably spray a bit on the opposite side. to balance.

Anyone ever try to use two or three different flex seal products to plug a hole? Like the glue to fill in the the hole then flex seal tape over the top then seal?

Interesting experiment. I tested Flex Seal against other products on my channel, but not on a tire. I wonder if on a lower pressure tire, like lawnmower, bicycle, or similar, would have better results.

[@Danielson1818]

I'm wondering the same thing. I have a fat 8" tire for my wheelbarrow that has a small pinhole in the inner tube. I think I have a chance with flex seal, but I have the clear kind. Wonder if that will make a difference?

[@Danielson1818]

@@Surteronarto Thanks for reminding me. I would NOT recommend flex seal by itself (Because of the air pressure). But, I did find an easy fix from another channel. Apparently, just super glue and a little bit of paper will fix small pinholes on inner tubes, and then I put 3 coats of flex seal over the paper patch, and it's been perfect over the last week... Hope that helps, because I watched a few videos to come up with a solution that works.
