I picked up my new '05 Slingshot Yellow SSR two weeks ago. So far I really enjoy it - EXCEPT - for one nagging design omission that continues to bother me - the lack of a spare tire. The onboard fix-a-flat kit is not very comforting. I will be using this beauty as a daily driver, so odds are someday........ Anyway, someone at work recommended a product called Ride-On. (www.ride-on.com) With this stuff, you don't wait until you have a problem, you install this product in your tires and it supposedly helps to dynamically balance as well as "heal" up to 1/8" punctures. It also cleans up with water when the tire is removed and is does not damage the rim with any corrosive material. Has anyone had any experience with this product? Thanks!
