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.
