Car tires, anyone? - Page 8

Yes, a radial *car* tire is definitely built differently from a
*motorcycle* radial.

The motorcycle radial has stiff rubber "flippers" to support the
sidewalls and the car tire doesn't have flippers.

Motorcycle tire engineers use the stiffness of the triangular-shaped
flippers as rubber springs...

It's OK for a car's wheel to move a little sideways in relation to the
tread during hard cornering.

Autocross racers adjust their tire pressure so the sidewalls will rub
the pavement just a tiny bit. If the sidewall doesn't rub a bit,
there's too much air in the tire.

I was talking to Doug Bingham about car tires on sidecar rigs after
looking at a Dutch EZ-S rig on a 1200 Bandit.

It had car wheels and car tires.

Doug builds and sells sidecars for a living and organizes the Griffith
Park Sidecar Rally every year.

He said that he'd tried radial car tires on solo bikes and that they
were squirrelly.

And, *nobody* in here has even mentioned *bias-ply* car tires on
motorcycles.

I don't know if you can even *buy* low-profile bias-ply tires.

 



You're as full of shit as a Christmas goose. I'm the only person I
know who has ever seen an X-15, other than the one in the Smithsonian.

I've actually *smelled* the X-15. I could tell it was in the hangar
from the moment I walked in the front door, the whole facility smelled
of ammonia.

I worked on the B-52 mother ships and actually saw some of the first
X-15
flights with the smaller 8-barrel engines. It was not as fast as an
F-104 fighter with the small engine.

I even went on an X-15 support flight to a dry lake near Hawthorne,
NV, which was one of the recovery sites if the rocket engine failed to
start.

Nevada to Edwards AFB was the limit of the X-15's range.

 



Um, yes, but they weren't going for range, and the X-15's peak
altitude of 67 miles was well beyond all but 0.00003% of the Earth's
atmosphere, making it the first real spacecraft; and it still beats
SpaceShipOne's record of 62.2 miles that was set some 40 years later.
It also still holds the all-time speed record for winged aircraft at
Mach 6.72.

Pretty impressive for a little rocket ship that was built clear back
in the 1950s.

 



SpaceShipOne's achievement was damned impressive, when you consider
that was a private company doing it, not a government-financed
project.


The space shuttle isn't an aircraft? Right...


Little? Chuck Yeager's X-1 was little, the X-15 was about twice as
long and four times as big.

 



Look it up, doofus.


And speaking of big, your ego seems to be doing just fine. And for
very little reason that the rest of us can see.
