I am old school and use common sense. I examine my tires before the trip, during every stop and after trip. I use the IR for bearing check as well. I stop every 1 1/2 hrs on the road to stretch and check, but mainly to stretch. I usually have my dogs and they need attention as well. If you are properly inflated for the load, and you have maintained your tire's age etc, no issues. Now if they are **** tires, all bets are off. Had my GY Marathon tire on my cargo trailer lay down on me but enough said about them here before.
