TPM is standard in the USA as it is mandatory in all new cars over there, and has been since September 2007.

I beleive the Canadian cars come with the FTM not the TPM.I know 100% that my wifes 335 w 19's came with FTM and I am thankfull for that as I did not have to bother with sensors on her snow tire package and as I have a track setup coming for the M at least I do not have to bother with the sensors.
