A target pressure specifier is configured to specify a target pressure for a tire and generate a target pressure signal indicative of the target pressure. A pressure monitor is configured to receive the target pressure signal, a current pressure signal indicative of a current pressure of the tire, and an indicator of a deliberate change in the current pressure and compare the current pressure signal with the target pressure signal responsive to the indicator. A status signal is generated indicative of a status of the current pressure signal relative to the target pressure signal. An audio generator is configured to receive the status signal and to generate a sound audible outside of the passenger compartment of the vehicle that is indicative of the status signal.

Methods and systems are provided for estimating a temperature of a tire. The method includes: receiving tire pressure data; and estimating a temperature of a tread of the tire based on the tire pressure data.

An apparatus, method and computer program product are provided for providing a tire pressure analysis. In one example, the apparatus receives first sensor data indicating a first tire pressure change associated with a first vehicle and causes a prediction model to generate a predicted cause of the first tire pressure change based on the first sensor data. The prediction model is trained based on historical data, the historical data defining a plurality of tire pressure signatures. Each of the plurality of tire pressure signatures correlates a cause of a second tire pressure change associated with a second vehicle to second sensor data indicating one or more tire pressure levels of the second vehicle over a period in which a wheel of the second vehicle completes a revolution. The apparatus further causes a notification of the predicted cause at a user interface associated with the first vehicle.
