I like TPMS. Sure, maybe its not 100% reliable, but neither is a tire gauge. Sure, we all always check our tire pressure... before every trip. Even when required to do a pre-trip, we all actually do it before checking the box, right
I do know TPMS is more accurate than "doesn't look low to me" gauge.
On everything ive got/use, there is no down side to the Tpms. Even if its broken, so what, it gives you a red or yellow tire light, but it's not like it puts it in limp mode or locks the transmission. Now, if there are vehicles that do that, that would probably change my mind.
