An update on my use of Halo Courier Berlin tyres.
To date, I've have three deflations. NONE were punctures. The first blowout was due to an ill-fitting tube. Bang! Yesterday was due to a pinchflat. I hadn't inflated it for a while, and I guess the pressure dropped to maybe 90psi, which under me, is fatal. Bang, she went. And the third was also yesterday. After fixing the tube, and refitting the tyre, I overinflated the tyre up to 140psi. Bang! Again.
It seems that my Rennkompressor pump and my portable WidPipe, may have a slight difference in the readings. I pumped to 140psi on the WindPipe, and she exploded like a balloon. Maybe the Rennkompressor's guage reads a few psi less at the same pressure as the Windpipe. At least I've learnt, to only overinflate to 130psi.
On checking my back tyre, I noticed that it was all cut to hell, with some deep and nasty looking gouges. I've now glued those all up. But I've used the tyres for quite a while now, and have never bothered even to take the bits of broken glass out. So far, its not punctured from any intrusions.
