Great back-up tubes for my on-road bikes with 700 x 28 & 30c tires. Their price is way much better compared from other sellers.

This inner tube cannot be inflated a lot when it is not installed in the outer tire, otherwise it will cause irreversible damage!

Please 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/72PSI When using rims with a no-ring-lip system according to ISO/TC 31.

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

If you inflate the tires in a cool garage in the morning (18°C / 65°F) and ride later at higher ambient temperatures (35°C / 95°F),it may result in an increase in inner tube pressure (e.g. 0.5 bar/8 PSI).

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

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