The tire gauge is compensated. If it wasn't, it would read 14.7 psi at rest.

Any gauge that reads zero at rest is called compensated. It compensated for whatever pressure is in the atmospehere that day.It's actually reading in PSIG, which stands for PSI gauge. There is also PSIA, which means PSI absolute, or not compensated. A PSIA gauge will read atmospheric pressure at rest.
