Safety Seal NS10007 Replacement Truck String Refills Model RT, Price/EA

I use these for my skid steer (tractor) the best. Other brands pop right off or just no good material. This brand top of the line they hold on for dear life.

These things have sealed holes I was sure would need a patch and they have held the life of the tire.

When plugging a tire, they do a good job of holding air in the tire.

These are the only ones we use. Don't mess with the rest. Perfect.

This is on a 2015 Toyota Prius VSo the material I think just having used it is mighty fine. Yep, had a screw imbed its self right between the tread and sidewall, second worst possible place to get a nail or screw besides the definite sidewall.So I've been experimenting for the past 3 months having this issue, gone through probably 2 other brands of of O'Reilley's and Auto zone brand tire plugs. The first time I just used a plug and some whatever rubber cement. Held probably for about 2-3 weeks, kept coming out slowly but surely, needing to cut off the excess. I decided to do it a different way, brand new ones from O'Reilley's, plus their cement. Same thing happens.I go to another O'Reilley's and get some rubber cement but this time researched and found you need Self-Vulcanizing cement, which pretty much every plug pack you find says self vulcanizing anyways. I also got myself some tire / innertube patch kit, for the thin strips of rubber it had, and some specifically noting Vulcanizing Rubber Cement. Thought, maybe I could cut some strips off and basically massage and rework some fresh rubber onto the surrounding plug to make it stay there like a rubber diaper, using a lighter to candle burn it for a bit to let it cure into the tire somehow afterwards.That's what worked for a long while.Every time I put a plug in though, it got much easier to push in because the hole was getting.. Bigger. So that was concerning having a bigger hold each time, contemplated even doing two of them in one go, tried putting two in the same eye of an insert tool, no way will that work..That trick worked for about 2 1/2 months maybe longer, quite a while, then today my low air sensor goes off of course, can you guess how much length I had left, 1/2 left inside. Pretty dangerous.But, I have the eyes of a hawk dealing with overheating and electrical failures for years with 3 cars so, I get it on time with 20 lbs of air still left, and by the way the tire is on the side next to the curb, a very steep curb the car is basically sideways every time I park right against that tire, doesn't help at all.So today with only 20 lbs of air left I go find a station with an air pump, pretty hard in San Bruno ish Cow Palace area, take the old one out with slip joint pliers, the surrounding vulcanized rubber was very well done, stayed on pretty well only the plug just couldn't stay adhered to the inner tire and hole. The rubber diaper I guess you could call it, wasn't strong enough to hold the plug in, the plug being in a tight space allowed it to un-adhere its self to the surrounding rubber so it protruded a little bit more over time, and started leaking.So I bring out the Trucker's plugs here I ordered a month ago just in case, and I'll tell you what the adhesion of these strips makes the other brands look like honey or water. The vulcanizing I'm not sure what they use but they definitely mix it differently, because the grip of this adhesion is so good that it was attaching its self to the metal insert tool I was using, I needed to use my pliars as a wall to force the plug off, that is how good this vulcanizing mix is they have on the plugs.The crap store bought plugs, comes off the tools like water, like honey compared to these plugs.Some morons out there may think that's a good thing for the crap plugs coming off so easily but they'd be wrong, see because you want this stuff as adhered to your tire rubber as possible.Something I would suggest to the future plugger, is if at all possible to cut yourself a small section of it and adhere that small piece to the center of your plug, massaging it in, that way if a plug were to start coming out every so often, the small bit will stop the plug from coming out almost like a nail head. That's actually what just happened to me by accident, some old part of the old plugs got onto these trucker plugs just by coincidence, and I feel like it will definitely stay in there if there were any reason for it to fall out anyways.I don't recommend that definitely, I suggest just plugging it in normally, no small piece.As for why I didn't go get another tire, all my tires are 80 worn, they charge you $120 for a new one, you get an uneven tread wear which screws up cars in so many ways, and I'm basically macgyver.One other thing I should mention I noticed is these trucker plugs when you light them on fire for a minute after pluggin them in and snipping the ends off (Plug trick I learned), that the goo actually adhered around the surrounding tire, other plugs don't do that they kind of kink back to straight.My idea is that over time when dirt gets into plugs they get into the slivers of the fabric or whatever they use, rots out the gooey vulcanization and air can get past that after a bit, so massaging the burnt rubber around.These worked with the average insert tool's eye, almost exactly the same size as the others.When you rip it out of its double layer of plastic for the first time you feel the quality in the grip of the adhesion.When several months go by I'll create a new post telling how it's going
