Air leaking from a tire is caused by many factors such as particles getting in between the tire and the wheel where the bead seats. Another factor for leaking tires is corrosion on the wheel itself which is causing surface imperfections allowing air to be leaking.

Start diagnosis by inspecting the fluid level in the power steering reservoir, inspect components where the fluids have accumulated, clean off any fluid from the components, apply to trace powder to components, start the vehicle and allow it to reach normal temperatures, turn the steering wheel the stops each direction 3-4 times creating maximum steering system pressure and determine the source of the leak.

This noise may be caused by the front strut jounce experiencing a slip/stick condition during cold temperatures.
