I highly recommend purchasing a digital infrared thermometer to keep in your tow vehicle. It keeps the guess work out of it and will give an early warning of any problems with tire pressures, brakes or bearings.

The actual temp is not what is important as this will change with conditions and even with the sun hitting one side of the camper while traveling. What you are looking for is that one tire, wheel or hub that is substantially hotter than the others on the same side of camper.

The IR Thermometer has alerted me to several malfunctions before they became disasters on our campers and other equipment/utility trailers.
