Update: Dominik informed us that the specs are not accurate and he will release official information next week. Stay tuned.
Did you know that Dominik designed a tire called XDomX? It's produced by company called Rubena. One of them weighs 1lbs (478g), the width is 1.6" and you can pump them up to 115PSI. A photo and details are available in the parts section: Rubena - XDomX
Hungarian pro rider Laszlo Tivadar is testing them at the moment and produced this promo video for his sponsor Velvart bike shop.
