Oki I have pretty much given up on adding a TPMS system. I keep reading horror stories about them detecting an issue long after a tire failed (typically a blowout) or not at all. I think I would rather check them every stop with a good gauge. That brings me to a question. How often do you test? We typically stay within 3.5 hours of home with at 1 stop for nature somewhere in that time. With longer trips how often should you check your tires ?
