I have a HF IR gun and love it for checking tire temps on all of my vehicles
Check after airing up for the trip and that is the base line for the trip. Log that so wonโt have too remember.
At each stop, whether bladder relief or fuel, check all the tires and log it. After a few trips know how my setup behaves...more so since I no longer own a trailer and borrow from church member/buddies/etc.
Of course, if a tire picks up a nail/etc during the trip...it either blows, or at the next stop will be higher temp than the others (how nails/etc and low PSI kills tires...increased flexing at high speed)
Ditto the radiator/hoses/etc of the engine bay...base line and can see changes during the trip
VERY useful and economical compared to what can happen if it is going south and donโt know it...
