Those tires are 60tpi and weigh 890g each.
Almost anything will weigh less and feel more lively.
A Panaracer Pasela PT 26x1.75" in folding bead is 460g.
You would have a wider tire for more comfort, a protection layer for flats, and save 1.9 pounds.
Or a rene herse Naches pass 26x1.8" tire in the standard casing weighs 350g. So that would save you 2.4#.
Thats crazy- drop 1.9-2.4# off a bike with just a change of tires and you get wider better rolling tires too.
Itll definitely make for a more fun riding bike!
