13. Maximum Permissible Inflation Pressure: Tire manufacturer's
maximum permissible pressure and/or the pressure at which the
maximum load can be carried by the tire. This pressure is normally
higher than the manufacturer's recommended cold inflation pressure
which can be found on either the tire label or certification label which is
located B-Pillar or the edge of the driver's door. The cold inflation
pressure should never be set lower than the recommended pressure on
the vehicle label.
The tire suppliers may have additional markings, notes or warnings such
as standard load, radial tubeless, etc.
