Its certainly something to think about. Just goes to show you live and learn all the time 8)
Just do it man, you will never look back.
That is good to know and seems a great way to ride a bike and avoid the hassle of punctures....
It will probably seal. You may not even know about it. When I change my tyres over, theres normally thorns and all sorts stuck in there. I had no idea. I once was on a long ride and my tyre was cut by glass, this is the worst one I have had as it was two big cuts in two places. I first realised something was up when I felt water spraying on me and thought some little sod was spraying me with something, before I saw the back wheel like a catherine wheel. It sealed, and I ran it low pressure (about 20) home. That tyre I had on for another 6 months. If it slashes too much to seal, then you can just pour out the sealant and stick a spare inner tube in. I have been running Stans for 5 years. The first time i did the Liverpool to Leeds canal, I had 6 punctures. Since i went tubeless, I'v never had a puncture that has stopped me. Im also tubeless on the road bike now.
So what happens if you get a nail in a tubeless tire - does it not go down ?
