Q. Does it fit any car in the world ?

A. Yes, if your vehicle has regular valve caps (Schrader).

Q. Can I custom my PSI pressure afterwards or show an universal pressure ?

A. No, these caps are set to a specific tire pressure, with a number of preset pressures, which cannot be adjusted.

Be sure to choose the correct cap to match the pressure as recommended by your vehicle manufacturer.

Q. What if the pressure I need is not on your list ? For example a 35 PSI ?

A. You may take the pressure up a bit, and use a 36 PSI to fit in this case.
