  • Method for detecting an underinflated tire by monitoring a work vehicle suspension
    Patent number: 4866419
    Abstract: In the field of off-highway trucks, tires represent a significant portion of operating expenses. Underinflated tires wear more quickly than properly inflated tires. This invention pertains to an apparatus for detecting an underinflated tire of a work vehicle (12) and displaying the information to the operator or service personnel. The apparatus senses internal pressures of preselected struts (16,18), and converts these signals into an indication of relative inflation pressures of the associated tires (32). When a tire is underinflated relative to another tire by a preselected amount, an underinflation signal is transmitted to a display. The display indicates to the operator that a tire is underinflated.
