How many of you guys have or do not have a TPMS?

I don't think ANY TPMS will solve all tire problems, but the goal is to keep an eye on tire pressures all the time. tire failure can usually be associated with low tire pressures, which result in higher tire temperatures, which break down the rubber even faster. Keep an eye on tire age - on our rigs tires usually "age out" (about 7 years) before they ever wear out. Even without visible sidewall cracking, tires can and do fail from the inside! TPMS simply add another level of protection. ST
