Tire Inflation Requirement
The California Air Resources Board (ARB) enforces regulations to reduce greenhouse gas emissions from vehicles operating inefficiently with under inflated tires. These regulations apply to vehicles with a gross vehicle weight rating of 10,000 pounds (lbs.) or less. Automotive service providers performing or offering to perform automotive maintenance or repair services in the state must:
- Check and inflate vehicle tires to the manufacturer recommended tire pressure rating, with air or nitrogen as appropriate, using a tire pressure gauge with a total permissible error of no more than plus/minus two lbs. per square inch, when performing maintenance or repair;
- Indicate on the vehicle service invoice that a tire inflation service was completed and specify the resulting pressure measurements;
- Have access to a tire inflation reference published within the last three years; and
- Keep a copy of the service invoice for at least three years and make the invoice available to ARB or an authorized representative upon request.
