I ran over a large piece of wood shaped like a thorn. The TPMS warned me the tire was rapidly loosing air. I stopped and confirmed it. As I was less than 1/4m from the house I went on home and in less than 5 min the tire was flat. If I had been on the freeway I wouldn't have known about it until it was destroyed and probably damaged the trailer.
Do you check the tire pressure before each trip? I do. I turn on the TPMS receiver and when I get finished hooking up I know the tire pressure in all 4 tires without touching a gauge. Peace of mind and convenience.
