bear in mind that temps on one side might be up to 10 degrees or more different from the other side. Factors, 1 side of trl heavier then the other, i.e. refer side, also which side of the trl is the sun on while driving down the road. I've seen the sun side be up to 20 degrees higher then the shade side, so another way to figure is if both tires on the same side are within 5 degrees of each other your ok.



Agreed. Check for variance. Also use for hvac, ground temp for dogs pads and anything automotive that moves/rotates.

I noticed that on mine one HOT sunny day heading North to go camping. Funny thing was, going home, South, the other side was the warmer side (about 5 degrees).

I usually see about 110 degrees on the hubs with my little Harbor Freight tool. Don't know how acurate it is but as long as I get the same reading every time I know things are good.

I rented a tandem trailer once. I found after driving a long ways I found that one tire was 30* hotter than the other 3. Tire pressure was 65 lb. on 3 and 35 lb. one the hot one.

I have no idea but if I put my hand on the hub and it's very much more than the ambient temp I assume there is a problem.


I too use a palm sensor. Was taught if tire/hub is too hot to comfortably hold your hand on. Then it's in need of attention prior to running at highway speeds again. So I guess 120°f would be about the max.


Sorry if this post seems long, I lacked the time to make it shorter.

I use one from Sears of about 5 yrs ago. If tire temp is 20 degrees different on the same side I use a gauge. Right inside rear always seems to be 20 degrees warmer than others. Side in sunlight may be 20 degrees warmer than the other side or so it seems.

I use one of these, and like said, you are looking for a difference. I have actually found that difference and a problem. I had a bearing too tight and brake adjusted a little too tight. It was about 40 degrees out and my hubs were running around 110, except for one that was running, IIRC somewhere around 165. Three of the drums, IIRC were around 115. The one was running somewhere over 150. This also made the tire run about 15 degrees higher than the other 3.

Hi All.

Very well done and said RV'ers. We have had ours for quite few years now. And beside all of the answers that have already been given, you can keep finding uses for them. Here is just another one or two. You can check around your doors and windows, for heat loss or cold air entering by the Temp Readings. You can do this in your RV and in your Home also. Want to find drafts in your RV or Home, "NO Problem". The number of uses for one, is only limited to your own thinking. Its a Great Tool to have and to use for so many things, and they don't cost all that much either. When we installed the "Drak Limo Tinting" on our Motorhome Windows, it told us exactely how much Temp Differance there was between the Tinting on a Window, and a window wihtout the Tinting. I could just keep going on and on, about how many uses that you can get with one of these. We never travel without ours. And I use ours often in the houuse for projects that I do also. "Get One", they are for sure worth the price. Good Luck. Happy Travels. Dan & Jill
