1) Send the wheel and tire assembly for an inspection to find the cause for the low tire pressure.
(b)
Replace the wheel and tire assembly installed on the opposite side of that axle. 1) Mark on the tire that it was on the same axle with a wheel
and tire assembly that was replaced because of low tire pressure. 2) Send the tire for inspection for damage.

Use the tire pressure gage to measure the nose landing gear tire pressures.
S 613-033
(11)
For the applicable airplane maximum taxi weight and tire, find the minimum nose tire service pressure.
S 613-034
(12)
Make sure both of the nose gear tires are above the minimum cold specified pressures for the airplane's maximum weight.
S 613-032
CAUTION: DO NOT DEFLATE A HOT TIRE TO LOWER THE PRESSURE TO THE AVERAGE
_______ PRESSURE VALUE. PRESSURE SHOULD NEVER BE BLED FROM A HOT TIRE TO ACHIEVE A SPECIFIED VALUE. DAMAGE TO EQUIPMENT CAN OCCUR.
(13) If the pressure of one tire is low 5% - 10% less than the other tire, inflate the tire with the low pressure to the pressure of the other tire.
WARNING:_______USE A REGULATED PRESSURE SOURCE TO SERVICE THE TIRES. AN UNREGULATED PRESSURE SOURCE CAN CAUSE INJURIES TO PERSONS AND DAMAGE TO EQUIPMEMNT.
