Took my Polaris rim and tire to a tire shop because the bead wouldn't seal, they said I needed a new rim. Jumped online looking for a cheaper solution, came across a redneck in youtube doing a live demo of inflating the tire with this stuff so I ordered enough to do all 4 tires. 21 days later, it hasnt lost an ounce of air! Not sure exactly what it does when it goes in the tire, but it made me a believer! Will order enough to do my Honda and my Gravely! ORDER IT AND FOLLOW THE DIRECTIONS, YOU WON'T REGRET IT!
