• Reduces flat tire rates due to tread punctures by 90%. Ceramic  fiber techonology is the key!

  • Protects rims against corrosion

  • Reduces air loss and helps to maintain tire pressure, resulting in extended tire life

  • Protects the environment. Our sealants contain only environmentally non-toxic propylene glycol

  • Increases retreadability

Simoniz® Sealtite™ Off-Road reduces flats by instantly and permanently sealing punctures up to 1/2" in diameter within the tread area.

Ceramic fibers hold the penetrating object in place to prevent further tire damage.

Through centrifugal force, Sealtite® Tire Sealant forms a protective layer over the entire interior of the tread

When a puncture occurs, ceramic fibers of lengths varying between 2mm and 20mm instantly  build a plug. The vehicle  weight  causes the puncture to expand when it is on the road’s flattened  surface,thereby allowing fibers to enter the puncture and cross-hatch, forming a fiber plug. Sealtite™  seals with or without  the puncturing object in the tread, however it is recommended that the penetrating  object be removed.

SIMONIZ® Sealtite™ OFF-ROAD is specially designed to prevent flats by sealing punctures in the tires of heavy-duty, slow-moving vehicles. This unique, environmentally friendly, wheel safe* formulation instantly and permanently seals tire punctures in tube and tubeless tires.

When a puncture occurs, air pressure forces the fibers into the opening. The ceramic fibers latch onto the rubber at the puncture site,  while additional fibers of varying lengths form a cross hatched plug.  These  ceramic plugs remain flexible,  and can stretch with the tire during diverse conditions (i.e., low inflation, full load, empty load).

SIMONIZ® Sealtite™ OFF-ROAD will seal punctures up to 1/2” in diameter in slow moving OTR vehicles. Larger punctures, beads, and sidewalls are often sealed as well.

Specially formulated for the OTR industry, this wheel safe*
formulation will last the life of the tire.

All Simoniz® Sealtite™ tire sealants and conditioners contain a  proprietary formulation of corrosion inhibitors that will keep wheels and fittings  protected and clean.
