Temp guns work great, no other way to tell the temp, I'm sure not going to put my fingers on the hubs to see if they are hot. After you come down a grade like 6 to 9 % I always pull over to shoot the break hubs. If they are hotter then my TV hubs, I wait awhile and let them cool down. That heat will transfer to your tires and that's when you can get a blowout. Been doing it this way for years, also I found out 1 time that 1 break was dragging making that wheel hotter. Stopped and had to readjust it. You will not know that feeling it with your finger. It's cheap protection, can be bought on Amazon or ebay.
