Bridgestone Blizzak winter tires do not require more or less inflation pressure than similar tires from other companies. Bridgestone recommends that Blizzak owners follow the inflation pressure guidelines included with their vehicles, but these guidelines are rarely specific to one brand of tire.
In addition to following the manufacturer's standard tire inflation pressure recommendations for a specific vehicle, Bridgestone recommends that owners of Blizzak tires regularly check the pressure of their tires to make sure pressure remains within optimal ranges. Bridgestone suggests that owners check tire pressure on cold tires. The company defines cold Blizzak tires as tires that have not been in use in the last three hours.
