Review: Fixed a Bead Sealing Issue - For traction in snow, I recently installed new "agricultural" style lugged front tires on a Simplicity garden tractor from around 1980. The tractor looks like it's survived a war, evidently having had a hard life as a workhorse owned by a school district. The front rims are rusty, and I naively thought the beads of these thick tires would seal properly anyway. They didn't. The jug of sealant ships with a valve core removal tool. Removing and reinstalling the cores is a piece of cake if you've never done it. I pumped a generous amount of the product into each tire and then did a few fast laps in a grassy paddock. It's a Kohler 19HP twin and it's a bit of a rocket. 😎 One tire sealed, the other didn't, and there was still a faint hiss. I added more product to that side and repeated the process. It seemed to hold. The next day that side was flat again, so I added more sealant and this time it held. Based on this experience, I'd say that instead of strictly following what the instructions recommended as an amount per tire, keep adding product in increments until the tire holds air. It's good stuff and it works. Will the tire self-heal if I puncture it? I don't know yet. It saved me the headache of having to remount these small tires or install tubes.
Review: This stuff is like magic in a bottle - OK, I bought this for my dad who is a farmer and his tractor tire has been leaking air for 10 years. He has taken it to different shops to try to get it repaired with no luck just would constantly put air in it every few days with the air compressor parked right next to the tractor so I bought this for a present for him after watching our review on YouTube about it and boy was he happy and couldn’t believe that it worked. He doesn’t have to put any air in at all whatsoever now also uses it on the four wheelers side-by-side three wheelers and lawn mowers Lives in Ohio, where the weather is hard and cold winters so the stuff is proven you’ll be super happy you got it. Life will be much better with it.

## Questions & Answers

**Q: This may be a dumb question, but will this product seal sidewall leaks?**
A: We have had good success with sidewall issues. You may need to manipulate the tire to ensure that the sealant makes contact with the leak. Feel free to call us if you have any additional questions, 1-800-577-3353.

**Q: How much is required for a 26X12-12 tire?**
A: For your tire size the recommended dosage is 72oz per tire.  Please feel free to call or office if you have any additional questions. 800-577-3353

**Q: Will this work on construction equipment such as backhoes?**
A: Unsure, probably depends on the size of the equipment and the size of the hole. It works is mowers, tractors, and 1/4 trucks.

**Q: Compressed air in can?**
A: No, this is not compressed air in a can. This product is a liquid tire sealant that is squeezed into a tire or tube, and then the tire or tube is reinflated with a tire pump or compressed air. It prevents or repairs flat tires.

### ⭐⭐⭐⭐⭐ Object causing puncture needs to be removed.
*by E***. on July 30, 2025*

Works well, easy to use. Only seals an open puncture. Object causing the puncture should be removed to seal properly. Cleans up easily with water.
