CAUTION: We highly recommend that the LED Smart Cap TPMS sensors be installed on metal valve stems. Metal valve stems are recommended because rubber valve stems can flex more, become brittle, or fatigue and crack over time. If you chose to use a rubber valve stem instead of a metal valve stem, you bear any and all responsibility should your rubber valve stem crack or fail. We as the manufacturer bear no responsibility. After installation, rotate the tire to make sure that the LED Smart Cap TPMS does not come in contact with any brake or suspension components (flex valve stem side to side and allow a minimum of ¼" clearance). The valve stem and LED Smart Cap should NOT protrude beyond the tire where they may come in contact with curbs or other objects.
