Tire pressure optimization system
View Patent ↗Aspects of the present disclosure are generally related to one or more systems, methods, and devices for providing an integrated tire inflation system, mounted on each tire, wheel, rim, axle, or structure of the vehicle, that communicates with a remote device (e.g., communication device located in the cab of the vehicle and/or a remote network entity) and obtains an optimal tire pressure from the network entity that is calculated to maximize fuel economy, tread life, load, or an environmental condition. In some examples, the integrated telematics system may periodically measure and transmit data associated with the tire to the communication device in the cab and/or to a network entity that may calculate the optimal tire pressure for each tire on the vehicle. The integrated telematics system may receive the optimal tire pressure information from the communication device and/or the network entity and automatically adjust the tire pressure accordingly.
