** TPMS alternative ** This product is for monitoring tire pressure: if the pressure of tire is 10% less than required, the tire pressure indicator will show red, otherwise it will show normal which is green. Each monitor is calibrated to the specified PSI, if your tire is under inflated, it will not show green. For example, if your recommended tire pressure is 40psi, then you should purchase our PSI 40 monitor caps. If your current tire pressure is under-inflated, when you install our monitor cap onto your tire, the cap will not show full green. ** Save gas, save tires, safer drive. ** AFTER INSTALLATION, DRIVE YOUR VEHICLE FOR 10 MILES OR MORE. The tire rotation primes the pressure monitors to accurately display tire pressure status in the clear window. ** We offer full range of PSI from 26, 28, 30, 32, 34, 36, 38, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, and 130.
