Seat a Tire Bead

A seated tire bead will promote a safe ride, maintain the integrity of the tire by protecting the inner tube, and help to prevent a flat tire while riding.

Step 1

Prepare the bike for maintenance. Turn off the bike, remove the battery, and press and hold the power button to discharge any residual charge.

Step 2

Check the tire bead around both sides of the rim. The tire bead should be fully seated on both sides of the rim with no gaps, the bead seat line should be evenly spaced from the rim around the wheel, and the inner tube should not be visible. Check both the front and rear tires.

If the tire bead is not fully seated proceed to the next step.

Step 3

Slowly release the air from the tube until the tire is mostly deflated. A hex key can be used to press down the valve to release the air.

Clean the entire tire bead with a paper towel and mild soapy water. The soap will help lubricate the tire as you seat the tire bead.

Press the tire bead into place until it is fully seated in the rim. Check that the inner tube does not get caught between the tire and rim. The bead seat line should align at an equal distance from the rim along the entire circumference of the tire. Check both sides of the tire to ensure that both sides remain seated.

Inflate the tire slightly to 10-15 PSI. Check that the tire bead is still seated securely.

If the tire bead is still fully seated continue to fill the tire until it is fully inflated. Inflate the tires to the PSI listed on the tire sidewall. Do not overinflate the tires.

The tire bead acts as the main support structure of the tire. The tire bead forms a wedge that grips the rim and keeps the tire secured in place once the inner tube is filled with air.  Check the tire during bike assembly, when changing an inner tube, when installing a new tire, after vigorous riding, and before every ride. The tire bead should always be seated on the rim with no visible gaps, indents, or damage.

You will need:

  • Water and mild liquid soap

  • Paper towel

  • Hex key

  • A bike pump with a Schrader valve and a pressure gauge
