Well, for about a year now I have had a very slow leak in one of my tires. It appears that I have had a few Thorn holes leaking air and I didn't want to enlarge them with a plug. This weekend myself , Son and Grandson went to the Deer Lease and I ran over many Thorny bushes to beat down many paths for future shooting lanes. Knowing that I would probably experience many more leaks, I decided to put slime in all tires to prevent more leaking tires. I purchased a Gallon Pump container and after removing all valve stem cores I pumped the recommended Slime to each tire which was 28 ounces per tire. That seems a little bit too much but I did it anyway. For those of you that have used this product, what are your thoughts? I plan to change my tires myself as I have a Harbor Freight changer that I have used many times. I have changed quite a few motorcycle tires using it. I am concerned of the mess to cleanup when I do change tires. What has been your experience changing tires with this product? By the way, the tires run very smooth afterwards! I used Dyna Beads in all Motorcycle tires and was very impressed with the balancing abilities of those!
