Not sure if I posted this story on our site, so here goes: I installed Slime tubes on my old Dyno Taxi beach cruiser. Great beach cruiser set up for riding the ladies on the handlebars! One night I'm riding to the oceanfront for fun and drink. Next thing I know I hear a faint hiss sound and something wet. Its a clear, lovely night so its not the wind or rain. I stop and look. I got a puncture in my front tire and was not only loosing air but I had a neon green stripe from my crotch to my forehead! So I still got a pinhole flat tire and a nice green racing stripe. So when I got home I pulled both Slime tubes and tossed them in the trash! The Tuffy liners combined with the new Conti Contact Plus City Reflex Tires and 30% thicker Goodyear tubes will hopefully be enough.
