I was looking for new tires recently & was surprised to see some nice touring tires available in tubeless-ready. The bike already has tubeless-ready rims so I'm thinking why not try the Schwalbe G-One Speed tire with tubeless. Actually I've never had a flat with Schwalbe tires incl light Supremes but tubeless could be nice insurance against a flat at an inconvenient time. The sealant & valves are not that expensive. I'm not good at patching tubes anyway so it's possible tubeless could be cheaper in the long run.
Riders who use a heavier tire to avoid flats can save a lot of rotating weight by switching to a lighter tubeless tire. Schwalbe says tubeless is the future, & they don't seem like the types to make idle inflated claims (pun intended).
