It shuts off the fuel line in most cars, but also slows you down
something fierce!

Ahm *hopin* they were steel-belted radials! If the
60 psi
wasn't for show room flat spots, then I have no idea what the 60 psi
was
for. All four tires were 60, pretty much on the nose. Go figger.
The ride was "sporty" to say the least. But mebbe
I'll try
it again, for a few more mpg's!

My civic had the same 60 psi on all four tires. Called the dealer the
next day to complain. They said they forgot to check the tires and
that they were inflated to 60 for transportation. Chains that secure
the wheels on the truck are used and the tires must not flex.

Still max pressure is 44 psi, right on the tire.

air has to go somewhere. ive got a road bike that runs 130psi tires, and
they need topping off twice a week. so its either diffusing thru the
rubber, or thru a leak in the valve stem or something.

Most, if not all new practical cars have shut off. At 40 mpg you save
about 0.00625 gallon when decelerating from 75 mph. A drop in the
bucket but going in neutral waste throw bearing, brakes pads on a
decline or just ruins engine mounts for everyday driving.

A rule of thumb: speed up briskly but gently, stay in gear, and slow
down (fiercely) using engine braking then brake to stop.

No, what the sad part is, is that people are going to believe that 100%
nitrogen diffuses through the tire at a slower rate than plain old air that
a compressor sucks out of the atmosphere.

Plain old air is 78% nitrogen.

ok then... so why nitrogen? or why not?

are nitrogen molecules bigger than oxygen molecules?
would that make a difference?
why do shock absorbers use a nitrogen charge?
wouldnt a charge of regular air work 78% as well?

all my tires have plain old air in em. if given a choice between the
two, for no extra charge, why not choose nitrogen?

You are the first person to mention nitrogen diffusion! It's oxygen that I
said diffuses out.

And I have corrected your attributions as well.

Depending on the tranny. If you are in a slushy in OD there is hardly
any engine braking.

I once read an article where Jay Leno talks about these. He said that
racers use Nitrogen because it doesn't have as much pressure variance as
the tire heats up, which makes "set it and forget it" possible. Otherwise
the tire might pop like John Kerry's hopes for the presidency.

You'd have to be some kind of flaming idiot to buy one of these for a Honda
Civic though.

It might reduce your gas consumption, but I've heard it causes a sharp
spike in your ether consumption. Still, it is handy to have a supply of
ether available. In case you want to huff it. Or a lawnmower needs
starting.

If you want more power, just dump a bucket of gas into your throttle body.
This creates a super-rich mixture which is good for some reason. I
frequently bounce off the wheelie bars in my '95 TC using this approach.
