Abstract:
1. A method for regulating tire air pressure, the tire having shoulders, a tread with a ground contacting portion, and defining lateral and longitudinal directions, the lateral direction being parallel to an axis of rotation of the tire, the longitudinal direction being perpendicular to the axis of rotation of the tire, the method comprising the steps of: dividing the ground contacting portion of the tread along the lateral direction into multiple zones positioned adjacent to each other along the lateral direction, the multiple zones including shoulder zone with each shoulder zone positioned along a respective shoulder of the tire, the multiple zones including one or more intermediate zones between the shoulder zones; selecting a range of tire air pressures and a range of tire loads; determining, for a load L identifying, from the selected range of tire air pressures, a preferred air pressure P repeating, over the selected range of tire loads L ascertaining an actual or anticipated tire load L adjusting tire air pressure during vehicle use to the preferred air pressure P
