Puncture resistance and safe inflation tips

Important: This inner tube should not be inflated a lot when it is not installed inside the outer tire, otherwise it can be damaged.

Use a manual air pump instead of high-speed air filling equipment such as air compressors or pumps.

Before inflating the RideNow tube, turn the valve inward (towards the center of the tire circle). Inflate a small amount until the inner tube is round; this pressure should be less than 0.5 bar/8 PSI.

Tire inflation pressure must not exceed 5 bar/72 PSI when using rims with a no-ring-lip system according to ISO/TC 31.

Every 3° (5°F) increase in temperature can increase tire pressure by about 1%.

If you inflate tires in a cool garage in the morning (18°C / 65°F) and ride later at higher ambient temperatures (35°C / 95°F), inner tube pressure may rise, for example by 0.5 bar/8 PSI.

Especially when riding on high-temperature black asphalt pavement with temperatures exceeding 65°C (150°F), tire pressure may easily exceed the allowable maximum value. Too high tire pressure can cause the tire to break away from the rim during cycling, which can result in injury.

If pneumatic tires are stored at 60°C (140°F) or higher, for example in a car in hot weather, deflate the inner tube to 1 bar/15 PSI to avoid valve deformation.
