Dear Sir/Madam Thanks for writing us in forum, The bike manufacturer recommended tire pressure is “cold pressure”. When you ride your bike to the gas station, the friction on the road will heat up your bike tires within a few minutes. Typically there will 1 psi (~7kPa) increase in air pressure for every 10 deg F (5.6 deg C) rise in temperature, and vice versa for decrease in air pressure. It is advisable to inflate the tire pressure with this compensated pressure above the recommended pressure. Should you have any issue arise, you may revert to us by writing an email to "cx@my-fobo.com" for further assistance, Best Regards Amir Bayati Customer Experience | Salutica Allied Solutions Sdn.
