My car tires are found to be over inflated by the dealer by 3 psi after my first service. I mean 3 units above the posted value on the door.

Is it ok to run like that?

Nothing to worry about. The 3 extra lbs will perhaps stiffen your ride very mildly but beyond that you will not have an issue. FYI, anything more than 3 lbs might be a concern but a couple of pounds over recommended is not a problem.

3 psi is nothing to worry about.

There is nothing to worry about.3 extra lbs is not any concern...

yes it ok ,if they told you and let you leave like that . yes it's okay, with humidity and air temp. tire pressure will fluctuate. If it bothers you take it to a tire shop they can check and adjust for you.
