Slime, Fix-a-Flat, or any other tire sealant can potentially block the airflow to a tire sensor or lead to incorrect tire pressure readings, therefore we do not recommended using these products with your TireMinder TPMS.
This is not to be confused with tire balancing products like Equal, which is safe to use with your TireMinder TPMS.
