I'm way past tired of airing up ATV tires, and Slime doesn't seem to seal much. What are you guys using? We're in Jim Hogg County.

This what I use. My Polaris using this and with Kevlar tires has not had a flat in over 10 years. Webb county.


I'll add that I understand that slime actually helps deteriorate tires from the inside but I know for a fact that it freezes. Nothing like walking out on a freezing morning only to find four flat tires from frozen slime.

Or FlatOut

All the farmers and ranchers up here in the Ozarks use this. We have honey locust trees that have thorns that are wicked.
It is permanent and does not corrode your wheels etc. Sold in every farm and ranch store up here.
I converted all my stuff to using it and have been happy.

Liquitube is what I use now. But I also have used TireSeal for decades in the Texas Mesquite. Mostly I used this because it is available at my ag supplier and they can put it in when I mount new tires. This is the product: https://www.texasrefinery.com/products/specialty-products/tireseal/

Liquitube is not available anywhere and I have to have it shipped.

Honestly, I don't know if either is 'better' than the other. I feel like these all work about the same, but I will say the Liquitube has better specs in terms of remaining liquid in colder temps.

When I say both work, I mean I my tires regularly hit mesquite thorns and random square nails on our ranch and they all seal up fine.

All quality sealants should have corrosion inhibitors, but I would give the nod to Liquitube if you have no preferences.

UltraSeal comes in several flavors, and it's about the same price as Liquitube. It's also available on Amazon which is handy as hell. Having read up on it, I'd say UltraSeal and Liquitube should be your main options here and probably getting whichever is available to you is the way to go.

Both are water soluble, glycol based, they won't freeze, they have corrosion inhibitors, and both are good as preventative maintenance and good for the life of the tire.

I've been trying to read and compare/contrast the two and I just don't see any serious difference between them.

Another vote for liquitube.

I have multi seal 2500 in my front tractor tires-pleased with how it's performed so far.

This is for 4 bottles (1 gallon) of Flat Out, from Tractor Supply. These go in easier/work better than their 1 gallon pump jug, which often clogs.

This stuff is made in Texas. It is Multi Seal's "consumer" product, vs. their large 5 gallon pails they sell labeled as Multi Seal. Good deal for $45 (will do all 4 tires on a UTV). Rated to seal 1/2" punctures, and ethylene gycol based, not water (Slime is water-based, will freeze/corrode).

I've used FlatOut when living in Texas and it was a great product but would not close up large punctures like stubs or dear antlers. It's good for up to 1/2" they say. Changed to Liquidtube because it's rated as non corrosive to your wheels or tires, lifetime rated product that won't freeze up here in the cold winters, and will seal larger punctures up to 3/4" according to them…but it's a bunch more expensive than Flat Out for sure. Depending on your needs and budget of which one is best I guess. Both better than the other stuff seems like.

Yeah, in something heavy (10k lb tractor), I could see how deer antlers/etc would be a concern. I've never had something that big poke through a 1200-1500 lb utv tire, just bunches of mesquite thorns, but the Liquitube or Multiseal 2500 (posted by others, above)might be a definite consideration, if that's a concern.

Good point.
Our main culprit up here is we have to constantly bush hog trails, pastures because damn little saplings grow back in a few months. When we bush hog them the stubs stick up 3-4" and are like bungee sticks.
I've ruined a couple of my can am 6 place tires this way.
Lots of guys foam fill their UTV tires up here cause of it … but then you feel like you are riding in a skid steer all the time and your fillings fall out of your teeth.

Used quadboss on two sets of atv tires. Lots of time in honey locust and never had to add air.

For sure foam fill will prevent flats but beat you to death. I had front tractor tires foam filled and funny but rubber finally wore off leaving only the foam. Ran that until I found airplane tires .

A lot of tractor tire discussion. OP asked about ATV tires. All/any on the above work, in addition to the green slime.

Well they were basically a warning of what others have tried to prevent flats or down time due to flats.
Another suggestion is Kevlar tires. I use these and still add sealant to the tires and have great success.

Yeah it's a good discussion. Lots of different products listed that people like.

I just think OP can't go wrong with any of them.

Slime specifically says to not leave it in your wheels for more than two years. They also say in some conditions it will corrode wheels, especially aluminum. Slime won't seal large punctures well.
ATV use or tractor tires, jeep tires, etc. withstanding, there are better products available for long term use better than Slime type of products is what some folks were saying on here I think.

Gempler's Ultra Seal

I've been using this for several years now, and it eliminated my mesquite thorn problem. It's good stuff (not cheap), and works much, much better than Slime.

I imagine some of the other brands mentioned here use a similar chemical formulation and so in the year 2026 one is probably just as good as another.

I think the Ultra Seal grade I use is good for up to 1/2" punctures. The one mentioned above that does 3/4" -- now that sounds impressive. That's a big damn hole.

Thanks for the replies! This group is great about sharing knowledge and experiences. Will get on the www and get something ordered!
