Does Pressure Affect Tyre Mass?

[captainjack2000]

Homework Statement

Just a quick question: does a fully inflated tyre have the same mass as a tyre that is punctured or uninflated?

Homework Equations

The Attempt at a Solution

The one that is fully inflated will have a greater pressure but I am not sure what this will mean in terms of the mass...

No, but not much more. The pressure is, of course, because of air in the tire. The fully inflated tire has more air inside it and so has the mass of that air added to the mass of the tire itself. Since air does not have a great deal of mass compared to the tire, the increase in mass is not very much.
