Sealed Leaky Beads on Beadlock wheels

Worked great on my slow leaking beadlock wheels

It works!

My brand new 2024 Polaris Sportsman 850 ultimate trail got a flat tire on the first ride! I didn't want to have to pull the wheel off and take it to a garage to get it plugged. I followed the instructions on how much to use and how. At first, it just spit out the tiny nail hole. I rode around the yard slowly for about 5 minutes. When I stopped, the leak was no more! It's still holding air 100% fine. I love this stuff for fixes out on the trail to keep me from being stranded. If you ride off trail away from home, this is a MUST have to take with you.

Fixed rose bush pin holes in side wall of garden tractor tires

Garden tractor had several pinhole slow leaks in side wall of two tires. They would leak down within a week, got to be a really hassle to put air in the tires every time I wanted to use it. In the past I would just put a tube in a tire like this, but figured I would give this product a try since it worked well in my automobile for several months now. Removed the two rear tires and added TireJect in both tires. Fixed the problem and it has been great never had to add any air and it has been over five months. Great product, A+++++++++
