Slime 10207 2-in-1 Tire & Tube Sealant Puncture Repair Sealant, 2-in-1, Premium, Prevent and Repair, suitable for all off-highway Tires and Tubes, Non-Toxic, Eco-Friendly, 1 Gallon jug

I’ve been using Slime tire sealant for my fat tire e-bike, and I can say with confidence that this product delivers exactly what it promises. The application is simple, the results are consistent, and the peace of mind it provides is invaluable. For anyone who rides regularly — whether for commuting, recreation, or deliveries — this is a product that pays for itself many times over.The first thing I appreciate about Slime is how easy it is to install. The bottle is well-designed, the instructions are clear, and the process takes just a few minutes. You simply deflate the tire, remove the valve core, squeeze in the recommended amount, reinstall the valve core, inflate, and spin the wheel to distribute the sealant evenly. No special tools, no mess, and no guesswork — just a straightforward, user-friendly process.Performance-wise, Slime does exactly what it’s supposed to do: seal punctures quickly and effectively. I’ve had nails, thorns, and sharp debris puncture my tires while riding, and in every case where the leak was within the tread area, Slime sealed it instantly. There’s something incredibly reassuring about hearing that faint hiss of air for a second, then watching it stop as the sealant does its job. It’s a real-time reminder that this product is actively protecting you from being stranded.What sets Slime apart from other sealants I’ve tried is its durability. Once applied, it stays active inside the tube for months, ready to respond to new punctures as they happen. It doesn’t dry out quickly, it doesn’t clump up, and it doesn’t cause balance issues with the tires. For someone who rides almost daily, that reliability is a huge plus.Another thing I respect about this product is that it’s non-toxic and environmentally friendly. If a bit of sealant escapes during a repair, I don’t have to worry about it harming the environment. It’s also water-soluble, making cleanup easy if I ever need to replace a tube or tire. That attention to safety and sustainability shows that the company isn’t just making a great product — they’re doing it responsibly.The value for the price is excellent. One bottle goes a long way, and when you factor in the cost of replacing tubes, paying for roadside repairs, or even the inconvenience of being late because of a flat, Slime is an investment in both savings and peace of mind. For delivery riders like me, it’s especially valuable — every flat avoided means another day of work uninterrupted.In short, Slime is one of those rare products that I can recommend without hesitation. It’s easy to use, effective, long-lasting, and backed by a company that clearly understands the needs of cyclists and e-bike riders. It has already saved me from countless headaches, and I plan to keep a bottle on hand at all times. If you ride regularly and haven’t tried it yet, you’re taking an unnecessary risk — this is one of the best preventative tools you can add to your maintenance kit.Verdict: Five stars for performance, ease of use, and overall value. Slime is a must-have for any serious rider who values reliability and wants to keep rolling no matter what’s on the road.

Bought this two years ago and put it in my bike tires. Flash forward 10,000 miles and I just got my first flat, but was saved because I had this in the tubes. I noticed my rear tire was soft while working on the bike, so I refilled it to 105 PSI. The next day while riding I heard a hissing noise, stopped and looked at my rear tire and saw slime leaking through a pin hole in the tire. After a few seconds the leak stopped and I continued on my ride for another 20 miles. Next day I went out again but this time the tire went flat. I should have changed the tube after seeing this stuff leaking out a hole.Bottom line is this saved me on multiple occasions from having a flat. That being said it won't stop huge holes and is not a long term solution if you get a leak. But, it will save you from flats you won't ever know about and flats you will know about.If you see it leaking out and then stop leaking, you'll probably be able to continue your ride, but should change the tube to be safe.

This stuff does exactly what it says it will. We have a lawn tractor that had a persistent issue with one of the front tires quickly going flat no matter how often or full I pumped it back up. We have a lot of small paddle cactus plants growing on the property and they have very stiff and very sharp spines. There were probably numerous punctures in the tire from those and this stuff fully sealed it off such that I haven't ever had to pump up that tire again. I'm gonna squirt the remainder in one of my bicycle tires that keeps going flat. I definitely recommend this stuff!

Excellent!!! Efficient, easy to install. Valve stem remover breaks constantly so minus 1 star.for that. Otherwise excellent product.

I use this is tractor tires and it works great. If the Slime won't stop the air leak, you should go to a new tire.

Excellent repairability results with my favorite basketball, which is prone to leaking air from the vent valve. Good value for money.

We live in an area with mesquite trees that shed limbs with 1" - 2" thorns. We've spent time tearing down tires and repairing inner-tubes on the cart and lawn tractor. Then we tried the green Slime. Very pleased with the outcome. Easy to apply, and so far its been very effective. In fact, on one occasion I pulled thorns out of a tire before I used the Slime, so I clearly saw the source of the air leak. After applying Slime the tire has held air and hasn't needed anymore attention. Suggestion: the stem removal tool that comes on the lid of the bottle is not effective on all tires, I suggest that you order a stem removal tool. They're inexpensive and if you need it, it'll pay for itself in one use.

Worked great. Fixed the leak in my Quad tire. After installing make sure you drive on it for a while.
