Will No-Flat, Seal seal bead or rim leaks?
Answer Yes. It may take a few days for it to seek out all the areas. The rim may be leaking from so much air pressure you may need to add air a few more times until the leak is permanently sealed. The more the tire is rotated the less time it will take for a bead leak to seal. Also some Aluminum rims, are very porous, and can leak air. You may think it is the tire that has a very slow leak, it could be the rim. No-Flat will Fix that !
