1. 1. Be familiar with the following questions:
      1. How does altitude and air temperature affect landing performance of aircraft tires?
      2. How often should on-wing aircraft tire pressures be verified?
      3. How much is the pressure of an aircraft wheel/tire assembly allowed to decrease in 24 hours?
      4. What is the cause of Chevron Cutting?
      5. What is the purpose of the Sidewall Vents?
   2. Perform visual inspection of wheel/tire assembly per job card including tread depth.
   3. Record the following:
      1. Tire Part Number and Size including Ply, Load and Speed Rating
      2. Tire Serial Number
      3. Retread Level
      4. Remaining Tire Skid Depth
   4. Record any noted conditions and damages on inspection form.  Determine tire disposition and required actions.
   5. Perform Tire Pressure Check and record readings.  Determine tire disposition and required actions.
