Safety Warning Warning: For use in high speed (over 65 mph) application only as a repair (exception: Trailer tires). May cause excessive vibration when installed on front tires or all four tires. To ensure safety, have tried and tested tires inspected by a tire professional occurs as soon as possible after punctures. Slime will not seal sidewall punctures or bead leaks, and should not be used with defective or damaged valve rims. Protective eyes must be used during installation. Slime tire sealant prevents flats and repairs on tubeless tires caused by punctures up to a quarter-inch. Non-flammable, non-toxic and non-aerosol, this sealant installs easily through the valve, and between the rim and the tire bead. Slime works repeatedly -- when a puncture occurs, the Escaping Air forces slime with anti-puncture fibroseal technology into the wound to seal the puncture. This product is virtually mess-free, cleans up with water, and lasts for up to two years.
