Ya know, I heard people talking about having Slime in their tires and preventing flats.
Well, I tried it and it just wasn't "all that".
I put in an full bottle just like the instructions said.
First, it is messy and difficult to get into the tire. A couple of times it would plug in the valve stem and I had to use a pin to open it up again.
Then, I noticed that it affected the balance of my tire- especially the front tire seemed to wobble.
Finally, the moment I was waiting for came today when I got a thorn puncture. My tire went as flat as a three week old road kill. "Hmm...", I thought, "maybe it will hold air if I re-inflate it." Nope, it didn't work at all. The air just hissed out.
At least with my experience, Slime was money down the (inner) tube.
