Has anyone ever used this product. I have a friend who used it on his Goldwing and swears by it. He took out the air from his tire , put the Ride-On in and then put the air back in. He said that the tires lasted longer with no weights on them, absolutely no vibration, and it protected against blow outs. Anyone else here aver try this product. If this be the case, changing one's own tires would be a breeze.
