20/10/2015 To what pressure should I inflate an air tire? The maximum pressure is always indicated on the tire itself. The BMXie’s and Jack&Josie’s included tires each have a pressure limit of 32 psi, which is equivalent to 2.2 bar. However, we recommend to always check the tire for the correct pressure indication and to never inflate your tires above this maximum pressure. Over-inflating your tires can lead to dangerous situations. If you are unsure about the inflation of your tires, please contact our team for additional information.
