Used in London city commuting for 3 weeks before having a puncture.

I had used it few years back with a inner tube in it and i didn't had a puncture in the whole trip in New Zealand i was very happy back then however this time i had to spend a whole morning trying to get it on my rims fitted as tubeless , really really hard to put it on. I end up trying to get it into shape with a inner tube as it wouldn't go up in pressure. Another couple of days and try take them off and put sealant in and try again, i don't have a compressor but my state of the art floor pump always worked on tubeless, in this occasion i failed. keep in mind its an absolute stubborn tyre to put on otherwise its just perfect and frankly it looks like a stunner with tan sidewalls
