I had a front tire unexpectedly go down on me the other day. I couldn't find anyone to fix it on a Sunday so I waited. I did a bit of research on this forum and found it interesting that Slime is kind of an accepted thing. Growing up I remember "fix a flat" and my dad saying that they will never work on your tire again if you use it. I figured this was the same.

Anyway....I used it today and the tire is good as new. I was very pleased. Good thing too. I had to dig a trench to have electrical run from my new garage to my shed.

I have used it by the gallons.... works well. I am sure those that fix tires may not like the mess it creates after the fact.

I've used it a couple of times.... after a while one tire kept loosing air and I brought it to the tire guy, he was busy so I took the time to clean the rim for him (he really appreciated it...) and since I put the slime in there, I felt obligated to do the dirty work....

Another tire, front tire on my lawn mower (I've told this story here before)... Mid afternoon I noticed it was over pressurized and showing it's aging cracks in the side wall. Decided I'll deal with this later since I had guest staying overnight (one in our old camper).

Next morning at breakfast, he ask WTF was the big explosion last night. No one in the house heard a thing. Later I walked down to the lawn mower and that front tire did indeed explode!!! Looked like a movie set from Ghostbusters, green slime all over the place....

I got slime in two out of 4 tires on my tractor. What was interesting was the rear tire had popped off the bead when it lost air. So I first had to get the tire to take air and get it back on the bead first. The pull the valve stem.

While I was pumping slime into the tire, It popped off the bead again 🤪🤪🤪🤪

It made pumping the slime into the tire much easier 😂🤣😂🤣😂🤣

I put about 3/4 of a bottle in the back tire. Got it back on the bead again, and taking air. Aired up the tire and then worked the tractor for a while.

It was a fight, but once aired up, it's held good for over a year now 😎😎😎

I use Slime but only in the tires on my ATV and side by side. Seems like every plant in the desert has thorns sticking out and those thorns are stiff enough to penetrate the thin ATV/UTV tires and cause slow leaks. Slime does a great job of stopping the leaks.

Not a fan for multiple reasons except in specific circumstances.

I've used FlatOut Off-Road because the rubber chunks in it will plug a hole in a non-tubed tire pretty quickly. I've also used on-road, which also works great.

What a friggin' mess when pulling a tire though, which has to be done if you're going to plug the tire because the FlatOut or Slime or whatever will interfere with the vulcanization of the plug goop. Cleanup with a garden hose or pressure washer is definitely doable, but man did I get wet (in the cold) cleaning that mess up (rims and tires).

With that experience I have lawn (the front have tubes added), industrial, and agriculture tires for the BX and run the appropriate tire for the job. If I were running over spines and puncturing tires (like some members here) then I'd probably use FlatOut Offroad to extend tire life.

The "self-balancing" of on-road Slime or FlatOut does work to a point, but for me I had to go 85 to get it to spread out and balance on multiple vehicles when dosed properly according to their instructions per each tire/wheel size, at which point it was clear it spread out and worked well. As a note, if the imbalance is beyond a certain point the wheel might not balance at all speeds, so "35 MPH and below" and "65 MPH and above" might be great but 45-55 not so good.

Once the tire wears to the point the additive can no longer balance it the additive has to be removed in order to spin the wheel on a tire balancer. For something like a Polaris Slingshot where there's no spare tire additive makes sense, but if you can carry a spare it's probably best to not use Slime or FlatOut.
