If you want the least amount of hassle you need tubeless ready tyres. I have used Maxxis Aspen and Ardent non tubeless and they work really well once you have them setup initially, which can be a bit of a chore.
However, I just fitted some Hutchinson Toro 29er’s which are tubeless ready and they inflated first time with a track pump. Bontrager also do really good tubeless ready tyres.
