X-tra-Seal Bead Sealer (32 oz.)

During tire mounting, a proper seal between the tire bead and the rim is what keeps air inside. When rims are corroded, pitted, or have surface irregularities, standard mounting alone may not achieve that seal. Xtra Seal Bead Sealer solves that problem with a thick, high-adhesion formula that clings to tire beads during installation and cures to form an airtight barrier.

The 32-ounce can comes with a built-in brush applicator, which makes it easy to coat the bead area evenly without creating a mess. The thick consistency is intentional; it stays where you put it instead of running off before the tire is mounted. Once cured, it bonds to irregular and pitted rim surfaces where a bare bead-to-rim fit would leak. This makes it especially useful for alloy wheels that have seen a few winters or steel rims that have developed surface corrosion.

The 32 oz size is a practical quantity for home mechanics working on a set of tires or for smaller shops that mount tires regularly. Apply it to the bead area before mounting, seat the tire, and inflate as normal.
