I did 35000 km with XZL -with tubes inside- in West Africa (Mauritania, Mali, Burkina, Niger, Benin, Togo), 50% on tarmac, 50% on other surfaces, sometimes very rough.
I only had 1 puncture in l'Aïr. They are very good, but becareful on wet tarmac.
f you choose to stay on main roads, you don't need this sort of tyres.
They need to be deflated quite low on sand,because they are narrow and so you need a good compressor.
I have a EMS compressor. No problem.
