According to a notice from SEMA, California automobile service providers can no longer use a tire’s age as an excuse for not checking a customer’s tire inflation pressure.
By law (signed in September 2010) all "automobile service providers" – including tire dealers – are required to check tire pressures for every vehicle being repaired at their facility. Under the law, service providers are required to inflate the tires to the recommended tire pressure rating using a gauge that is accurate within 2 psi.
The provider must note on the invoice that the tire inflation service was completed and then keep a copy of the service invoice for at least three years. The customer may decline the check if the customer affirms that a check had already been done within the last 30 days, or they will have it checked within the next seven days.
The law applies to auto maintenance/repair providers but not to auto parts distributers/retailers, auto body/paint facilities, auto glass installers or wreckers/dismantlers.
Recently, California Gov. Jerry Brown signed into law a bill that removes tire age as a reason to deny checking a vehicle’s tire pressure. The law recognizes that there is no national tire aging standard and, therefore, referencing tire age in a California regulation creates liability exposure to the service and repair industry.
Vehicle service providers still have the right to refuse to check the pressure if the tire is “unsafe” (excessive tread wear, for example) or damaged (cracking, bulges or ply separation).
