30 punctures in 3 wheels in one easy go. Thorns.
You can get em.
Even just getting one puncture in the rear tyre can be a pain.
Take off the rear panniers, then the trailer, let down the tyre to get it past the brake pads, take off the wheel, repair, then reassemble.
There are two preventative measures to avoid this situation.
Slime, or its liquid latex equivalents, works for a while. But once you get a bigger hole, it seems impossible to patch satisfactorily. The Slime seems incompatible with the patch glue, and after a short while, any patch leaks.
Thornproof tubes are a better bet. The tubes are about 4 times thicker than a standard tube. In conjunction with a decent tyre, they do a reasonable job in hindering thorn penetration. 5000 km without a puncture is pretty reasonable.
Most replacement tubes for 26” wheels in Australia come with a Schraeder, or car tyre, valve. You can generally pick up a no-name brand thornproof in any country town or Kmart.
A 700 tube is less available away from the major towns, thornproof or not.
Be prepared.
