I like the heat gun because I can shoot it into areas of the hubs and disc brakes that I could not reach with my hand. Most wheels on an RV have a center piece that covers the actual hub. I can also shoot the back side of the assembly. Whatever method you use you are looking for abnormalities.

I’d be very surprised if the majority of people could get within 20 degrees of the actual temperature when using there hand. The majority of IR guns are very accurate and reliable! They are used in many industrial facilities where they are used on equipment costing hundreds of thousands of $. If they were unreliable or inaccurate....I don’t think that they would be used a tool by plant/industrial employees/operators! I used them for many years monitoring compressor valve temperatures, pipe temperatures, electric motor housing and bearing temperatures. They are considered indispensable by many in the industrial field. It is completely illogical to someone “not” to take advantage of inexpensive technology to save themselves money and aggravation! memtb

Not to mention, when I check my truck rear differential temperature.....I don’t have to crawl under the truck! memtb

That's one of the reasons I have one.

It's not the actual temperature they're after when using their hands, it's whether the warmth feels all about the same.

Since I have one it's hard to argue the benefits one might argue by not having one. But, mine takes pictures and allows you to see where the heat is. I can tell you from experience, that the tire heat is on the tread, but the bearing heat is not on an area you can touch from the outside of the tire or hub, it's on the inside. You can't touch that area and some bearings can be over 200 degrees. Good luck with your hand. Also, heat is relative, so you are looking for all to be about the same, not an absolute number. In addition, a failed brake has no heat. You're not going to feel that with your hand.

I’ll buy that to a point! But, I want to know the temperature differential between tires/hubs/ brake drums(if applicable) for each side of the unit.....example , all should be similar on the same side of the unit. Yes....anyone can determine “if” one component is significantly hotter than it’s counterparts...But, by that time it’s likely too likely too late for preventive maintenance!

An example being.... with the IR gun I can determine not only if one component is “warmer” than it’s counterparts.... but determine within a degree or two, the difference from side to side of the unit, caused by loading, road crown, sunlight exposure, etc.! Maybe I am “overreacting” to the importance of this little tool.....but, I’m forming an intense displeasure for roadside or campground work performed in single digit or triple digit temperatures! If this can save me a tire, bearing/hub failure, a dragging brake, or as mentioned a failing truck differential.....it’s a monetary win and some piece of mind! memtb

My TPMS will show me that the wheels on the sunny side will be 10° warmer than the other. Now, whether bearing heat will show at the edge of the rim.. I don't know.

2oldman, the TPSS system is great......but, the IR gun, is just another tool in your arsenal! memtb

thats not true, if you put your hand on the centre hub cover you will feel if the brakes or berrings are running hot. if it warm your good, if you pull your hand back you may have an issue. you said your self it is over 200 degrees, its all metal and the hub cover will give a bit of air space so you dont instantly melt skin. now you wont know if it is brakes or a berring with out a little more investagation but your not trying to do that on a quick stop, just checking to make sure tires and centre hubs are running at simular temps, this tells you everything is good. if I feel a hot one I will start looking deeper which may mean gettin gout my gun and trying to find the hotest part of the hub from the back.
