Is a car tire that is partly deflated more dence, less dense, or of the same density as a totally inflated tire? Why?

A partly-deflated tire is more dense than a full-inflated one. The lost air reduces the volume of the tire but hardly changes the mass at all, so you have about the same mass occupying a smaller volume.

The air pressure is what gives the tire its form and pressure. It takes Billions of particles to make any diffrence at all. So Partialy deflated means that there is less pressure. Less pressure means less air. The ratio of molicues diffrence to volume diffrence is huge so the more inflated the more dense the air while more deflated the LESS dense the air. Your first responder was way off. I am an engineer. Trust me
