Tire Temperature

(1/7) > >>

We all know that a tire that is running hot can be a problem.  I often check mine at rest stops with a laser temperature gun.  If you spot one that is noticeably hotter than the rest, you need to pay special attention to it.  

Found this on Amazon, its a great deal ($16.88) and it has good ratings.

If all else fails, I got mine back in 2007 at Sears.  It works pretty well.

Some guy named Bentley gave me one of those Temperature guns for a present a few years back.  It has many uses.  Like checking the AC output vs intake,  Breaks or wheel temperature, refrigerator temperature.  Use your imagination.  The price Tim listed is good, and $5 less is even better.

What is the guidance on temperatures considered normal for our tires after driving the coach for a couple hours?

I have this laser, but had to pay $25 for it.  ??)

Bill Sprague:
I don't think you have a laser.  You might have an IR meter with a laser pointer.  

I bought one.  Mine is a Craftsman.  I learned they do not measure actual temperature.  The measure reflected energy and "translate" to degrees of temperature.  Try putting a white plate and a black plate in the oven.  Take them out and point the ray gun at them.  The reflected temperature will be different because black reflects energy differently than black.  

So, when it comes to tires, the idea is to look for differences.  It makes no difference what energy my tires reflect to my IR thermometer.   It matters only what yours is doing.  As you walk around the coach, see if the tires and hubs match.  

Perhaps the most interesting time to do this is after a long down hill run.  If tire or wheel is significantly hotter than the rest, it is doing more than it's share of the work.  If it is significantly colder, it is doing less than it should.

After you get used to the IR gun, try the same technique with your hand.  The surprise to me was that, for relative differences, my hand works as well as the $50 meter.  Apparently our hands are pretty well trained by using them to test for shower temperature each day!
