Hhmmm...not so sure about using Slime. Bought some tires with it already in it, inflated to proper specs and used them for a few weeks almost daily. We had a few days below freezing, went out to the shed where I keep the bikes and found one of the tires had exploded...all over the bike(s), the walls, the ceiling, etc. Went out a few days later, the other tire had exploded. But YMMV. :wink:
