  RS – Standard auto or light truck tires, for injuries up to 1/8”
  RT – Over-the-road truck tires
  RHE – Agricultural and construction equipment. Not for high-speed use. Multiple inserts may be used.

• Is a plugged tire considered a permanent repair?
  No. A patch or a plug alone is not considered a permanent repair.

• Is a plug with liquid patch considered a permanent repair?
  The Rubber Manufacturers Association considered it permanent in the 1990s. Not sure today, current standards may vary.

• What does “Self-Vulcanizing”/ “Self-Vulcanized” mean?
  These terms refer to rubber compounds that cure (vulcanize) on their own, without requiring external heat. “Self-Vulcanizing” was the term originally used by the inventors.
  
  Key benefits on vulcanized rubber:
  Increased strength: More resistant to stress and deformation
  Enhanced elasticity: Vulcanized rubber retains its shape and returns to its original form after stretching or compression.
  Improved heat resistance: It can withstand higher temperatures without softening or degrading as easily as unvulcanized rubber.
  Better solvent resistance: Vulcanized rubber swells less when exposed to solvents.
  Improved abrasion resistance: It is more resistant to wear and tear from friction.
