I did not see any information about tubeless or not ..
Royal Enfield has just described them as CEAT dual purpose tyres and no details about their tubeless nature has been given till date. The bike uses spoke wheels and chances are more that the tyres will be tubeless. RE may also offer Pirelli off-road tyres as an option for the new Himalayan. it is powered by a 411 cc long stroke engine producing 24.5 बीएचपी और 32 टोक़ के एनएम.
