I cannot comment on how the Aero 8 sensors are set up; however, if it is anything like the Mustang, the sensors are attached to a band that is strapped around the inside drum of the wheel.
If the tyres gets changed, a common problem is that the band becomes loose (or the fitter knocks it off all together) and the sensors start malfunctioning as a result. I am not sure if this is how the Aero 8 was set up but it is worth considering.
