You are NOT over the TOP on this one. Actually you are very smart in doing it that way. First off the TPMS cannot give you accurate temps of your wheel hubs and rubber tires. It just ain't going to happen.
I do the very same thing. I let the TPMS do its thing which it is BEST at doing and that is to monitor the air pressure in each tire. Then I use a good IR gun to measure both the tire temp and wheel hub temp while walking around the coach and trailer. That allows me to get some the stiffness out of my bones at the same time.
You should measure the tire temp about 2-3 inches or so below where the tread meets the sidewall. For the hubs and wheels just pick a point that is close to the center and easy to get to.
One important point in using an IR gun is to get it close to your target so it doesn't measure a very broad area of the surface. Most guns will tell you what the ratio is for distance to target area for each gun.
