Yes, we definitely have the TPMS - it alerted me to a slow leak from a screw embedded in my drivers side rear on Friday. I guess it's possible your tyre place could have transplanted the monitors for you - I discussed it with Bob Jane while they were doing the puncture repair for me, we were talking about Yokohamas when the Hankooks are slicks, $289 for 215/40/18 in A-drive R01's, and the potential to change rims and end up with a less expensive size... If they put new rims on a car with TPMS they keep the TPMS operative.
