Centrifugal force
6 Answers
Is it true or falce? A tyre on a racing bike or car which doesn't have a valve cap fitted will lose pressure during a race due to centrifugal force acting on the valve. If true how does it overcome the pressure contained in the tyre?

i have been involved in the lower end of the racing scene, ie rally , saloon car..not heard of that one before. Cant answer for the likes of F1/F3/GT, the valve cap is a dust cap not a seal to prevent air leakage.
I have a 640bhp American super car capable 200+ mph in the workshop next to me and thats got standard valves

To start with, "Centrifugal Force" is a fictitious force that doesn't exist and is used to supplement Newton's 2nd Law of Motion.
However, the force generated by the rotation of the wheel great enough to overcome the tyre pressure holding the valve closed would also cause the tyre to move away from the rim. Such a force could be generated but it would require a rotational speed far greater than that which is achieved by a moving vehicle.
In other words, false.
