All E9x M3s use sensors in each wheel. The wheel sensor changed slightly for the 2010 model year so there are two different PNs (make sure you get the original one if replacing them for your car.) Euro, Canadian (?) and other markets still use sensors on the car that detect changes in rotational speed to determine pressure and whether a tire is going down (no wheel sensors). This is the way it was on the E46 M3 even in the US.
