Product Review: Slime Tire Sealant

Slime Tire Sealant

There is nothing worse than a flat tire, or a leaking tire. For years I have used Fix-A-Flat to seal up problem tires, but recently had a tire Fix-A-Flatcouldn't handle. Someone suggested I try Slime, the green tire sealant. I wondered if Slime could perform where Fix-A-Flat could not.

Real World Testing

I was skeptical that Slime Tire Sealant would work for this blown out tire. Unlike Fix-A-Flat that uses a propellant in the can to push the sealant into the tire, Slime used just the pressure of squeezing the bottle by hand. But then I looked closer and realized the folks at Slime came up with a better way to get the sealant into the tire. They provide a tool to get the center of the valve stem out so the Slime flows uninterrupted into the tire. You squeeze the whole bottle in and ever so often rotate the tire to get even distribution of the Slime. According to their website Slime relies on a "state-of-the-art blend of environmentally friendly fibers, binders, polymers and proprietary congealing agents which intertwine and clot within the puncture." Basically, they made the Slime with plenty of good stuff for fixing problem tires. The real question is did it work in this case -- where Fix-A-Flat failed -- and the answer is yes, the Slime outperformed the competition. This is now my new go-to tire sealant, I bought four bottles yesterday!

Slime Tire Sealant, Member socom45

This stuff works great. I had a lawnmower tire that had a slow leak, it sealed it and that was it. For the others that rated this product keep in mind that Slime does not inflate tires. Slime also will not seal or repair a leak in a valve stem or a puncture in a sidewall of a tire. Slime works on punctures in the tread portion of the tire, the part that touches the road. For the lady who's husband tried to fix a valve stem leak this would not work because of physics (the force of the rotating tire kept the Slime along the outer part of the tire and not by the valve stem) also Slime is not a permanent fix for on road tires. If those little lead weights can throw a tire in and out of balence imagine what 30oz of Slime will do in a road tire. I liked Slime so much I put it in the tires of my Polaris Ranger, but it is for off road only.
