• 20 x 2.125 means:

  • 20 inches = outer diameter

  • 2.125 inches = tire width

• ISO 406 = fits rims marked 20 x 1.50–2.125

• Ensure rim tape is in good condition before mounting.

• Inflate gradually to 40 PSI, checking bead seating evenly around the rim.

• Avoid overinflation; this can damage sidewalls or pop the bead.
