Below is a link to NHTSA's Tire Pressure Survey:
https://www.nhtsa.gov/sites/nhtsa.go...repressure.pdf
In results Tables #4 and 5, pages 17 & 18, the survey lists "Tire Labeling"(tire sidewall) as the primary source used for determining proper inflation pressure.
Now while this survey is over twenty years old, it points to a habit or behavior that needs changing, at least at the time the survey was conducted.
So the purpose of this thread is actually less about tires and inflation, and more about brainstorming how to educate drivers and change habits regarding where to find proper inflation pressure information.
Why does John or Jane Doe driver go immediately to reading their tire sidewalls for inflation pressures?
And how do we change the habit of John or Jane Doe driver from doing so, to, looking elsewhere(on the vehicle itself, or in the vehicle's owners/operators manual)?
