Did you know that there is a CA regulation that states garages must inflate tires to the recommended pressure every time they provide an automotive service on the car?


The California Air Resource’s Board, on September 1, 2010, issued the Tire Pressure Regulation in an effort to reduce greenhouse gas emissions.


The regulation requires that every time a vehicle under 10,000 lbs is brought in for an “automotive service”  they must:


  • Check and inflate each vehicle’s tires to the recommended tire pressure rating, with air or nitrogen, as appropriate, at the time of performing any automotive maintenance or repair service.
  • Indicate on the vehicle service invoice that a tire inflation service was completed and the tire pressure measurements after the service were performed.
  • Perform the tire pressure service using a tire pressure gauge with a total permissible error no greater than + two (2) pounds per square inch (psi).
  • Have access to a tire inflation reference that is current within three years of publication.
  • Keep a copy of the service invoice for a minimum of three years, and make the vehicle service invoice available to the ARB, or its authorized representative upon request.


I doubt a lot of this takes place, especially not the paperwork.  But it is nice to know because you can freely ask the mechanic next time to check the tire pressure and they’d have to do it for free.  Yes, it is a small item that you can do yourself at the gas station, but hey, it’s one less task to do!
