Flat profing A tire,is not possible according to Murphys
law. I have the tires that came with the bike and A tire liner. I was going about
25 between traffic and parked cars I run over A car key. the key pushed
the tire liner aside and POW the tire blowed.The back of the bike was all over the
place.For years I used continentl town and country 26-1.9 with tire liners
the same thing the police use. In about five years I had one flat.
I ran over A allen wrench.There A little $$$$ but you get what you pay for.
I road to work and back 26 miles round trip so im talking thousands of miles (no motor)
