LifeLine Inner Tube - 20 x 2.1-2.35

This LifeLine inner tube is designed for 20-inch rims and fits tire widths between 40mm and 62mm (approximately 1.5 to 2.35 inches).

It features a standard 48mm Schrader valve, which is commonly found on many bicycles and compatible with most standard bike pumps.

It is recommended to use this tube within the specified width range of 40-62mm (1.5-2.35 inches) for optimal performance and to prevent damage or rapid deflation.

This tube is suitable for 20-inch wheels used on various types of bicycles, including BMX, folding bikes, and some children's bikes, making it versatile for both road and trail use within its size specifications.

Store spare inner tubes in a cool, dry place away from direct sunlight and extreme temperatures. Avoid folding them tightly for extended periods.

The inner diameter specified for this tube is 406mm, which is standard for 20-inch rims compatible with this tire width range.

Ensure the valve stem is seated correctly in the rim and that the tube is not pinched between the tire bead and rim. Check for any punctures on the new tube before full inflation.

Ensure the tube is only lightly inflated to give it shape. Work the tire bead onto the rim systematically, using tire levers only as a last resort to avoid pinching the tube.

Check and maintain correct tire pressure as recommended on the tire sidewall. Ensure the tire is not worn and that no sharp objects are embedded in the tire tread.
