You will be better served with a good tire plug repair kit.
I guess in an emergency, the goo will save the day, but you may need to buy a new tire to replace an otherwise repairable tire.
From slime.com, regarding tire and TPMS:
Currently, there are two types of TPMS devices available: Direct and Indirect. SLiME Tire Sealant’s TPMS formulation is compatible with all TPMS systems. However, it is important to note that once installed, Slime Tire Sealant may come in contact with the sensor in a way that renders the sensor TEMPORARILY inoperable until it is properly cleaned, inspected and re-installed by a tire care professional.
Because SLiME is a water soluble flat repair treatment, it is easily removed from the tire with water. At the time the affected tire is inspected by a tire care professional, they should clean the sealant from the tire, prepare the area and repair with a Rubber Manufacturer’s Association (RMA) approved patch/plug. The TPMS device should also be cleaned off with water to remove any sealant which may have come into contact with the device. Do not use any fine objects to ream and clean the small pressure sensor opening as it may damage the electronics. After the repaired tire is replaced and inflated the TPMS system will resume operating as normal.
