They are very nice. You can get an inexpensive one at Radio Shack.

I use one to do a quick check on the wheel/tire temps when we stop at rest areas or other stops. All I'm looking for is a tire or wheel that is drastically different than the other three. This could indicate a problem such as a dragging brake pad or whatever. If all four are in the same temp range then I feel all is ok. After a few times of checking the tempuratures you get a feel for what should be normal for your rig. It only takes a minute or two to check the tire temps.

Yeah, I do what Pete Hanson does. I look for a significant difference. And like he says after a few times you get to know exactly what to look for. I really like these little devices. Gives me some real peace of mind.

I drove to the top of Pikes Peak late this summer and on the trip back down the mountain the forest rangers had a check point to check the temp of your brakes. If you overheated them they had you pull over and take a 15 min brake cooling stop. They were checking the temp with a infared didital gun.

Jay D.,
Did they say what temp was overheating? Wouldn't there be different temps for different brake systems? Just curious.

As I remember; if your brakes were 400% or more, you had to pull over and wait. They were getting the readings off of front only. Most autos built by mid 70's had front disc.

I don't know what temperature is a problem but it doesn't take long to learn what is normal for your rig. I look for how much variation between wheels, for example, while understanding some difference will exist just because the sun is hitting one side, for example. However, you will notice if there is a large difference.
I like to "hit", with the laser, the tires, the hubs (for wheel bearing heat) and sometimes the brake drums and discs. It's interesting on the trailer to note whether all brakes are sharing the load pretty much equally. If one axle's brakes are considerably lower temperature, then maybe that axle's brakes are not working or need adjusting.

Jay D.,
Did you mean to say 400 degrees?
