If there are paint marks on the wheel/tire assembly, make sure that the position of the tire related to the wheel is the same.

B. Visual Inspection of the Tires
(1) Make sure that the aircraft tires are in the correct condition to continue to operate on the aircraft:
-
make sure that there are no air leaks,
-
make sure that there is no damage by friction,
-
make sure that they are worn equally,
-
make sure that there are no cuts and flat spots,
-remove the wheel when the tire is worn to the base of any groove in any location or if you can see any reinforcing material (metal or fabric).
NOTE : Refer to the limits for the use of the tires. They are related
____
to the type and make of the tire.
(2)
Make sure that the tire pressure is in the specified limits (Ref. TASK 32-41-00-210-003).
(3)
Obey the tire mixability precautions (Ref. TASK 32-41-00-910-001).

Remove the wheel when the tire shows signs of a tread bulge (make a mark on the bulge before you deflate the tire) (Ref. TASK 32-41-11-000-006) (Ref. TASK 32-41-11-400-006) or (Ref. TASK 32-41-12-000-001) (Ref. TASK 32-41-12-400-001).
(5)
If the tread is not worn equally, make sure that the wheels are aligned correctly (if it is necessary remove the wheel and put it on the opposite axle (Ref. TASK 32-41-11-000-006) (Ref. TASK 32-41-11-400-006) or (Ref. TASK 32-41-12-000-001) (Ref. TASK 32-41-12-400-001)). If you find tread wear on the shoulder of the tire, inflate the tire to the nominal inflation pressure plus 10 per cent.
NOTE : This 10 per cent increase gives the new maximum of the Normal
____ Operating Range (N.O.R.) and not a new Nominal Pressure (P.N.). Example: For a Nominal Pressure of 200 PSI, the maximum of the
N.O.R. becomes 220 PSI.

C. Tire Wear Deterioration Characteristics (Ref. Fig. 605/TASK 32-41-00-991-003, 606/TASK 32-41-00-991-007, 607/TASK
R 32-41-00-991-004, 608/TASK 32-41-00-991-008, 609/TASK 32-41-00-991-009, 610/TASK 32-41-00-991-036)
(1)
Under inflated.
See Pressure Table : (Ref. TASK 32-41-00-210-003)
If tires are not inflated sufficiently :
-their shoulders wear too much,
-too much flex heating can occur
(2)
Worn Beyond Limits If the tire is worn to the reinforcing material (metal or fabric), you must remove the tire and the retreader must inspect it.
(3)
Tread rubber reversion (usually caused by a wet or icy runway). You can see this condition when there is an oval area in the tread. It is almost the same as a skid but the rubber shows signs of burns. You must remove the tire if damage extends to or into the reinforcing material, of if the out-of-balance is not satisfactory.
