I need to replace a tire on my Bianchi Varsity hybrid city bike. The
original Panaracer Ridge Line 2 tires (700 x 35C) are light knobby
treads, but these tires no longer exist.

I have switched to Schwalbe now, they have an additional neoprene layer
which makes them broken-glass proof. About 50% more expensive than
normal ones, but better than constantly patching flat tires.
