Anti-Puncture Tyres At-a-glance

It is not the thicker rubber but the tread that gives the lateral movements. The Twin Rail design is asking for trouble.

I have used Continental Travel Contacts for the last year and they are fine (smooth contact patch but knobbly sides as I ride 60/40 off/on road with them)

Put mine back on after winter. Calculated the exact PSI I needed frant and back, and realised they actually do ride well on tarmac. The pattern seems to be useless for any off-road surface, too hard for the central slick section to sink into though. Wet grass is a bit too much fun with them.

Still they do ride well for such a multi purpose, well protected tyre.
