LiquTube 32 oz. Premium Tire Sealant

This kind of worked but I am still going to replace the tire.

First found some of this at my local hardware store,and was instantly hooked! This awesome sealant permanently seals even large holes, and lasts for a good long time in tubed or tubeless mountain bike tires. About 4oz per tire is enough to really stop leaks and punctures- I live in goathead central and have literally gotten 10 goatheads per tire without so much as a hiss. This sealant is also miles ahead of Slime which I've had limited success with, providing a good permanent seal (compared to Slime's non-permanent enough-to-limp-home compound). I use this on my downhill bike paired with thicker Kenda tubes, and have been flat-free in some pretty rough stuff.Highly recommended!

It was a good idea, I’ll give them that, but it just doesn’t work in practice. It’s a goop with fiberglass strands in it and you put it in through the valve stem (after removing the valve). Unfortunately, when you squeeze it in, it pressurizes and the fiberglass locks together, so your valve stem locks up solid. Then you have to try to drill out the fiberglass (don’t try to push it in, because it just balls up and will roll around in your tire after you’re done, ask me how I know) without scraping the valve stem or the valve stem will leak as well, compounding your problems. Save your money, take it to a tire shop.

Fixed flat right away and saved myself from having to purchase another trailer tire! Very pleased

Not as advertised similar but should work

Product was expensive. Did not hold air in my tires. Would not recommend.

If you get the actual Liquitube product, I hope your experience was as good as mine. After trying Slime and all the fix a flat products, this one worked on a slow/medium slow rim leak. This was after I had been to Discount Tire and another tire shop that said the age and chrome in my rim was causing the leak and the only answer was a new rim. Since the rim expensive and part of a set and fine otherwise, I tried this product. I added it a little differently than the directions. I knew where the leak was on the edge of the rim, so I positioned the tire valve on top so product would enter the tire at the top and roll down the internal sides. Then I backed the car up to move the valve position and did it again and went for a quick drive. That was the last of the leak and it's been over a year. I'm totally blown away that this product works as advertised.

Didn't work on my lawn mower
