Yumin Ultralight Bike Inner Tube 700 X 18-32C Road Bicycle TPU Tire 700C 65mm Length French Valve Super Light Tube

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 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.
