Feature:
This inner tube cannot be inflated to a large amount when it is not installed in the outer tire, otherwise it will cause irreversible damage!
Please use a manual inflation pump and do not use high-speed inflation equipment such as air compressors or pumps.
Before inflating a RideNow tube, turn the valve inward (toward the center of the tire circle). Inflate slightly until the inner tube is rounded; the pressure should be less than 0.5 bar/8 PSI.
When using rims with ringless lip in accordance with ISO/TC 31, the tire inflation pressure must not exceed 5 bar/72PSI.
Tire pressure will increase approximately 1% for every 3° (5°F) increase in temperature.
If you inflate your tires in the morning in a cool garage (18°C / 65°F) and then ride in a warmer ambient temperature (35°C / 95°F), this may result in an increase in inner tube pressure (e.g. 0.5 bar /8 PSI).
Especially when riding on hot black asphalt roads with temperatures exceeding 65°C (150°F), tire pressures can easily exceed the maximum allowed. Additionally, excessive tire pressure may cause the tire to come off the rim while riding, resulting in a risk of injury.
If pneumatic tires are stored at temperatures of 60°C (140°F) or higher (such as in a car on a hot day), deflate the inner tube to 1 bar/15 PSI to avoid valve deformation.
