The temps you see from the TPMS and the IR thermometer should be in the same 'ballpark' but I doubt that they would ever totally agree. The main thing that you are looking for with either system is drastic differences in in temps on one wheel/tire. A variation on 10-15 degrees could be normal. Too many variables, sunnyside, shade, pavement temp, rain, day, night, ambient temps....... .
If your checking sidewalls, do ALL sidewall, if checking tread, do ALL treads. Also check hub temps when you have the IR out. A neighbour at one campground said that a combination of the TPMS and IR thermometer saved his bacon on one trip. The TMPS showed one front tire getting hotter than the others, but still not alarming the TPMS. When he stopped to check it out, the hub was over 700 degrees, Workhouse brake problems.
The main thing with either systems is to make sure that they stay within the same range (maybe 10-15 degrees). If you worry about keeping them identical, you will go crazy.
