I put ride on in my tires. Does it work? I don't really know, but I haven't gotten a flat so maybe it is? It did seem to help with the balance, especially the front. I removed all the weights when I added it. I noticed right away on the first ride that the bars didn't vibrate as much from the front tire shimmy. I have a SR244 in 5.10 on the front, much bigger than stock.
