Using a tire minder, or any other tire pressure/temp monitor, what is too hot for a temp reading. Not looking for reason, low pressure sunny side or near exhaust etc. just what be considered too hot...
I use a IR temp gun on the side of my tires near the tread… easiest place to temp the inside dual and highest temp I’ve seen is 140. Not sure of the relationship of the temp at a valve stem and the side of the tire. Have read that you should start worrying at 180 but 150 would worry me based on many years of checking.
