The 349-version however runs as well as chewing gum at low pressure and is very sensitive to punctures (ordinary ones as well as snakebites) and you are even in danger of damaging your rim at that low pressure. At or above 100 PSI it runs like hell and suffers far less from punctures, judging from my experience.
