Great vid!
Very good explanations covering both sides of the
of the topic.
A fellow I ride with was pretty neggo about darksiding as well. I found a vid of some type of bagger on a race track draggin in the corners and sent it to him. Darksiding is no longer an issue between us.

I went to the dark side on my 98 Valkerie. It took me a couple blocks to get used to it. By far it outlasted my motorcycle rear tire.
The negative= My wife and I road on concrete and had to drive on a dirt/gravel road with some pot holes. I was strong then. I had her get off the bike and walk. Another 100 feet and I parked it and walked the rest of the way. I nearly dropped it a few times. My arms were 18's back then and could press 305. Week as a kitten these days and I'll keep my MC rear tire on my, new to me, 94 GL1500.
Bottom line, if you remain on concrete or blacktop, go for the darkside and enjoy 3 or 4 times the life of your tire. I think I was running a dunlop and I had to grind off a wire holder ( Squirrel Cage?) on the fender so it would fit. Shiney side up!

Excellent presentation -
You looked at all the available facts AND much of the science (as we appreciate from you)
One thing you did mention but perhaps gets discounted a bit is there are SOME people (like me) -
Who did try it and not like it --

I tried a Darkside tire on my Goldwing for 30,000 miles -

it DID work -- it DID deliver more miles per Dollar -it DID stop & start well - it DID corner ok
it DID stick in the rain - it DID work in the dry - it DID give a good ride - it DID hold pressure

The CAR TIRE does a lot of things we wish motorcycle tires would do --

EXCEPT (for me) -
It felt kinda weird all the time -
I felt it push (think Nascar) often as it continued to drive me straight ahead
It wanted to stand UP straight rather than lean over - I had to consequently continue to steer in the corners all the time
while on a MT one can set the lean and ride through the turn.
I DID NOT check the final drive often cause the tire lasted so long (no damage but I wonder?)
I was NOT confident in a deep lean over although I could and did scrap the pegs at the Dragon while on a CT.

it DOES work - But (for me) it was a weird feeling and I returned to the sensation of a motorcycle tire
There is no such thing as a cheap motorcycle and buying tires is part of the equation -

I'm on my second car tire. I like it.
I watched Scott's video. Very good.
But I can simplify that whole video down to one line.

That's a bit like saying "Your keys are always in the last place you look."

Why would most people try something they would never recommend?

It very interesting to look at the comments on the YouTube video. Virtually all of the negative comments are claiming things that are debunked IN the video itself. It's very clear that the people writing those comments have not actually watched the video. They're commenting on the video's TITLE, not the content of the video itself.

Amazing even in the turn the rear didn't wallow.
Grip breaking torque didn't wrinkle the sidewalls.
SHAME something like a CT isn't readily available for our Touring Bikes.

Reading tnrough the comments its stated as a Michelin 195-55.
Watching the vid closely after he drills the second set of holes the winter mountian icon is visible.
Looking at images with that info I think it might be this run flat

Fred
The uploader responded to my query as to the make of the tire. Said it was a 8 year old Michelin that is no longer made. Runs a Bridgestone Driveguard now.

I dare say a CT that fits our touring bikes is probably more readily available than a MT.

I was kinda dreaming out loud saying Run-Flat and Long Lasting MT should easily be available for large & touring bikes.
The weight and mileage we put on them supersedes cost factors and install intervals when on extended road trips. I ride year round and easily ride 20k p-year, that's 2 rear MT's. Install 2 tires myself for about $450-ish & a shop $1200-ish.

So install a run flat CT and job done.

There *is* a company that makes a 'bead-retention' (not run-flat) tire for police use only - Dunlop.

Ask them *why* they don't make these available to the general public. :shock:

Bead retention is for extreme conditions, like cops cars in pursuit. We need RunFlats to minimally get somewhere safely.
I can't imagine our rims with probable holes drilled for said retention's IF that's how they work.

a regular MC tire, run on low pressure WILL loosen from the bead. you never know it until you high side at speed, or fall over at 5mph. bead detention is not something that should scare you.

Goldwings have their tires mounted VERY tightly - they are pretty tough to mount and de-mount. I've had challenges breaking the bead on them when changing tires. The last time I changed a MC tire on my bike, I had the (pneumatic) tire machine applying full force to the tire bead and it still took me beating on it with a dead blow hammer at the same time to get it to break free.

I don't worry about bead retention. :)

Nor do I. :mrgreen:

In fact, I should probably dig my spare rim out of storage, have the worn tire removed and disposed of, and get it powder coated. :lol:
