Does Altitude Make Bike Tires Lose Air Pressure?
Does Altitude Make Bike Tires Lose Air Pressure? Altitude (ft.) Air Pressure (psi) 10,000 10.1 How does altitude affect air pressure and temperature? As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.
