Went to the Darkside(car tire)today

Lets not forget about the guys running motorcycle tires till the cords are showing or not checking air pressure in them. Either one would also cause a car tire to fail prematurely.
Does this make a car tire safer?
Also if I do this search, is it going to point me to a study comparing motorcycle tire failures to car tire failures (installed on a motorcycle)?

I have looked at tire construction differences between ct and mt and mts are constructed differently then CTs are in the sidewall area. They are constructed this way because mt spend more time up on edge then a CT does. MTs have a stiffer sidewall then CTs do due to the way the sidwalls of MTs are constructed.
Also, I haven't seen any vid where the rider was really cornering much, scraping things as many of us do. The more centrifugal force, the more downpressure on the tire, and therefore the more flex.
Percentages - really? What about the percentage of riders on CT's or the percentage of their millions of miles without incident? Don't you think that if ANY CT's were failing (assuming having tread and air) on bikes, we'd be getting our ASSES handed to us in a basket???
Funny, that ain't happened. Just 2 Khumo runflats, run flat and bald.
First Darksiders to restart the idea are the Goldwingers, who've been doing it en masse for many years now. Those bikes are heavy, damn powerful and can outlean most Harleys. Go on THEIR websites and tell THEM it don't work. Be ready to have your *** handed back to you.
Personally, I have ZERO doubt that the CT on the back of a Cruiser is MUCH safer than a MT in all departments save one: the tendency to follow grooves slightly more than a bike tire will. (I75 around my house is raingrooved) And that isn't bothering anyone, since it still goes where ya point it.
And again...they ain't for everyone, so just don't if ya won't.

They'd better, or you'd be riding on the rim. CT's have that wonderful flex that they're built for that simply keeps half the tread on the deck for those of us who choose to ride them. Unfortunately, of all the videos I've seen, only 2 had a decent amount of flex - most are running far too much pressure, probably from the common suggestion to start at 40 lbs. One way some of us check a tire out to begin with is to get a buddy to ride behind and adjust pressure until it halves the tread in a corner.

No, Deuuce, it doesn't work that way. You lean a little more, the sidewall flexes a little more. This is why its so important to find the right pressure for your bike and riding style. It never goes into the sidewall or the edge of the tire shoulder, it doesn't fall of the shoulder, and it doesn't have an abrupt transition, like a worn out in the center D407.
And you're claiming the sidewall will flex further to accommodate that? And that isn't unstable? Because if you adjust the tire inflation high enough, it will be on its sidewall at that lean angle with a contact patch of seriously compromised quality.
A CT unstable? huh?
I was tempted to go find an empty parking lot and lay my bike down on the crash bar and take a picture of what the CT looks like leaning that far. But I got to reading your posts and its evident that you just keep making things up, like your assumption above, and if I took a picture or not it wouldn't make a difference, so you are on your own.
After reading your posts, I still can't understand how can you be arguing something that you don't know, simply drawing your own conclusions. But God bless America, we can all say what we want, hehe.

Key words: improved in the twisties.
Now leave the rear tire at that pressure and experiment with pressure in the front tire. Start with max pressure as stated in the sidewall and go down from there. Also check the steering bearings adjustment, this has a lot to do with stability. The dealer screwed the adjustment on mine, so I had to learn to do it myself, and once I got it right, the combination of this adjustment, tire pressures, and the CT, it became a very stable platform, at low or high speeds, rain or shine, sidewinds or headwinds, and its a delight in the street. Something simple like a short run to the supermarket is a treat, flicking my bike from side to side, the whole bike feels like it is one piece. It sure wasn't like that when I bought it.
In my case, I had a front end wobble and I raised the front tire pressure, I had a bad air pressure gauge when I started, and this was throwing me off, but once I raised the pressure, the wobble was almost gone. I had very light steering at high speeds and I tightened the front steering bearings and that was it. The last 10,000 miles have been trouble free, except for three flats.
I adjusted the steering bearings three times until I got it right, a little on the tight side. On the front I am running an 18" E3 radial at 38 PSI (41 on the sidewall) and the CT stays at 30 PSI solo or two-up.
Don't get discouraged. It might take a little work, until you get it right. Some bikes require a lot of experimenting to get it right, like mine, and some take no work, like my buddy's '07 Ultra on a Vredestein. He didn't have to do nothing, lol.

Naysayers, if you own a 2010-2012 HD go check your front mc tire. Dunlop 408's are known for cracked side walls and splits in the threads. These have been found in tires coming right off the truck with zero miles.
Dunlop may need to do a recall on these.
Car tires don't sound too bad now, huh.
The rest of us, keep an eye on those front Dunlops.

Oh, 18k now with 3mm to go to the CENTER wear bars.
I had to tighten up the softail shocks almost all the way to make this bike act right - which made it smoother. Then adding the CT made it even much more so. Nothing to the front end for problems, but I did thicken the fork oil and add a 5/8" PCV spacer over the springs to keep the head up in the twisties. Just can't afford ride valves.
