Method and apparatus are disclosed to facilitate TPMS broadcast mode selection. An example vehicle comprises sensors, a processor, and memory. The sensor are to generate vehicle dynamics information (VDI). The processor is in communication with the memory and with the sensors. The processor is configured to: estimate relative pitch and roll angles using the VDI, estimate a tire normal force using the relative pitch and roll angles and the VDI, estimate a tire rolling resistance using the tire normal force, and estimate a tire longitudinal force and a tire lateral force based on the tire rolling resistance and the VDI.
