everybody talks bad about the TPMS sensors cause most guys put aftermarket wheels on and dont swap the sensors and get the dummy light. on a stock vehicle, the TPMS sensors will notify you if the tire is more than 20% out of threshold. this can save your tire in many instances. if you had a slow leak and it went un noticed for several weeks, you can severely wear a tire out running it low for a few weeks. by having the sensors and dummy light in the dash, you are notified if any tire is low.
i personally love mine, i have never had a low tire, or ever seen my dummy light come on, but having the peace of mind knowing i have 4 little aliens inside my wheel that do nothing but monitor my tire pressure gives me peace of mind. i went ahead and bought an extra set of sensors in case i ever do buy another set of wheels or if the local tire shop breaks one when mounting new tires, because that seems to be the problem most folks see.
