Not, since there's a rubber valve.
TPMS uses metal valve like this:
BTW, if you're in Ontario, Canada, and have a canadian BMW X5, you don't need TPMS, since the canadian system's like in Europe, where they use ABS sensors as TPMS replacement.
Since ABS sensor "counts" the wheel rotation when braking, the same system's used when driving.
A wheel completing a rotation more rapidly than the other's deemed as deflated.
