The use of tire sealants is not recommended for vehicles equipped with the Tire Pressure Monitoring system. Tire sealants may clog tire pressure sensors.Tire pressure sensor valve stem caps and cores are specially designed for the sensors. Due to risk of corrosion, do not use a standard valve stem cap or core in a tire pressure sensor in place of the original equipment style sensor cap and core.It is not recommended to install a tire pressure sensor in an aftermarket wheel. Use tire pressure sensors in original style factory wheels only.Any time a sensor is to be reinstalled in a wheel, a new seal, cap and valve core must be installed on the stem to ensure air tight sealing.TPM thresholds have been established for the original tire size equipped on the vehicle. Use original size tires only to maintain system accuracy.
