I have to agree over the thought that when you spend a lot of money on
something you tend to ignore what may not meet your expectations..However if
there were nothing else to evaluate...the ride comfort alone sells me on the
tubeless clincher tire..From what I understand about the specific
Shimano/Hutchinson technology, lower air pressure is designed in and not
necessarily the root/only cause for smoother ride experience.even at the
lower air pressure rolling resistance is claimed to be lower (I do not have
any way to test that so I have to depend on what Shimano & Hutchinson have
to say, after all, why would they lie?? Hey Look I know what you are going
to say.).All I really know is what my butt, hands and average ride speeds
tell me.they all have improved...Bonus?? No more pinch flats!!.....if I do
get a flat I can put a tube in as easily as a regular clincher, and be on my
way. I save a small about of weight (no tube), while the tires aren't cheap
they cost no more than any high end clincher and less that tubular...and I
get a great ride, they also seem to conform to the road better when in a
high speed corner...Like disc brakes on Mountain bikes.I don't think I will
be going back to the older technology..

Tubeless Road Tires are a new enough product that there isn't much
real-world data just yet. Nothing that the marketing department hasn't
tampered with, at any rate.
So all we have to go on at the present time is anecdotal reviews of people
who now swear by Tubeless tires. I suppose if I dropped $900-$1400 on a new
product, I'd want it to be everything I'd hoped for, too.
But on the issue of rolling resistance, the best info I've found comes from
