Nearly 1.5 kg of tire per wheel (and tubeless at that). Sacre
avoirdupois, Batman! That mass is partially offset by wallet lightening
at $120-225 per tire. Shoot, my Compass tires suddenly seem like a
bargain. Maybe one can forego the formerly de rigeur boinger fork with
big marshmallows like these; that would be a decent tradeoff and would
further offset the increased mass.

Now, just because I have zero use for tires like this doesn't mean no
one does, I suppose. But yeek! The mass and the cost!

Now now, you're ignoring the advantage of "momentum"! How old-fashioned
to disparage it and talk about mere "mass."

Anyway, I've thought about this a lot, and I'm sure they haven't figured
out the optimum wheel+tire size yet. It's actually 28.15" also known as
715. I'm not buying another mountain bike until they start selling
"seven-fifteens."

(Notice the last two digits are the same in inches or metric. That
proves it's cosmic, man.)
