A method for detecting a leaking vehicle tire (e.g. from a puncture) by determining the vehicle is tilted. First and second image sensors on the vehicle respectively capture images of first and second reference features on opposite sides of the vehicle, for example indentations in the car body 372a, 372b or door handles (382a, 382b; fig. 3C). The reference points are located at substantially the same height on the vehicle body, meaning misalignment indicates a tire may be leaking. The images are aligned and compared to determine if the reference features are aligned. If misaligned, actions are taken, for example outputting a warning to the driver, modifying braking or steering control, or disabling an autonomous mode. Tire leaking may be verified by repeatedly comparing images of reference features. Tire pressures, height of the tires above the ground, height of a vehicle body part above the ground and/or a safe travel distance for the tires may also be calculated. The image sensors may be wide angle fish-eye cameras which are part of a 360 degree surround view system (see figures 2 and 3A), with the images transformed to a common perspective view for comparison (as in figures 3B, 3C).
