Did a trip around lake Michigan about a week ago. Starting in Chicago,by the time I was in Mackinaw I had a flat. I was carrying a slime kit with me consisting of a bottle of slime, small compressor, and attachments. Pulled out the screw like instructions recommended and filled tire with slime, it held for short time and started leaking again. Did this about 3x's than put the screw back in that I took out and rode all the way back to Chicago. I will not be using slime again but the port. compressor was handy. I'll try the ride-on next time.
