I disagree. I've been running Nu-tecks for over 8000 total commuting miles and haven't flatted once. If the OP switches to Nu-Tecks @ 130 psi for 28mm+ and 115 psi for 20mm I'll GUARANTEE he wont get a flat and wont be 'slowed down'(much
) by airless tires either. But, GET THE MOUNTING TOOL! You wont be sorry.
Schwalbe Marathon Plus, puncture resistant tubes, Spinskinz tire liners and a street sweeper ahead of you on your route everyday and eventually you're going to have a flat. THAT I can guarantee, too.
