A tire pressure monitoring system (10) and method is disclosed. The system comprises: a first tire (12a, 12b, 12c, 12d) mounted on a first end of an axle (88, 90) and a second tire (12a, 12b, 12c, 12d) mounted on a second end of the axle (88, 90), wherein the first and second tires and the axle support a vehicle (14); a first sensor (30) mounted on the first tire for measuring a pressure of the first tire; a second sensor (30) mounted on the second tire for measuring a pressure of the second tire;means (36) for transmitting measured pressure data from the first sensor and the second sensor to a processor (38); and a tire pressure model (54) configured for being executed on the processor (38), the tire pressure model (54) including: an aggregator (58) that accumulates the measured pressure data (60) from the first sensor and the second sensor; a noise filter (70) that is configured to filter sensor noise and to generate filtered pressure data (72) from the measured tire pressure data (60); a detection module (76) configured for receiving the filtered pressure data (72) and for determining when an air pressure leak occurs in at least one of the first tire and the second tire; and a leak notification (104) which can be generated by the tire pressure model (54) when the air pressure leak occurs.
