Hey guys, I just wanted to alert you all to a tire black-vinyl treatment this is pretty darned good! I have no affiliation with Yamaha whatsoever, I actually stumbled across the product to use on my boat's vinyl. I gave it a shot on my tires and was very surprised. It makes them a deep black, without the great oily look, and it lasts! I just heard that it may be discontinued. Maybe if you guys give it shot, and like it. They will reconsider.
