There are 2 different valve stem hole sizes on all rims. The most common size is found on all passenger cars. (Its i believe 2 1/4). There is a larger size that is found on a majority of farm/tractor trailer rims and some older trailer rims. (I believe its a 2 5/8 hole). as far as the ford tpsm system, most fords have band sensors. they take an basic valve stem. I understand that this forum is almost a year old, but if you still looking for more information, i'd be more than happy to help the best i can. i would need a little more information tho.
