name Don
age 40s

Question - I am a Weight Reduction Engineer at Lockheed
Aircraft. One of my fellow worker suggested using helium in the tires as
a 3 lb savings. After I finished laughing I realized he was serious. I
have included his original E-mail to me. Questions Will the helium stay
in the tires and how much weight do you see this saving.

Don,

I was teasing you a little when I suggested using Helium in the tires.

A little closer but still dirty look seems to indicate that over three
pounds is possible per ship set. Dirty because I do not have all the
numbers exactly and made some guesses...

One way to tell for sure is weigh a tire empty, then pump it up with air. See what the difference is. Probably not worth it, or everyone would already be on it. Since I had to add so much weight to my car, it definitely would never help.
