Tire sealants that come with a kit containing a portable 12-volt air compressor are generally better than those that only contain an aerosol can. While the initial expense for the compressor kit is more, owners can replace the sealant once they use it.
Regardless of the type of sealant a driver uses, the fix is temporary. Drivers should take the vehicle to a tire repair shop and have the flat fixed properly. There is a tendency for consumers to overuse these products, which can make repairs more expensive. The repair facility must clean the sticky residue from the tire before making a repair. Drivers of vehicles with larger tires should purchase sealants the manufacturer designates for such special use.
