Tire Wear-Deterioration Characteristics
NOTE:
(1)
(2)
This procedure is given for information only.
Under inflated:
If the tires are not inflated to the correct value:
The shoulders can wear too much.
-
The tires will bend too much and become hot.
-
The tires can move on the wheels and decrease the braking effect.
Over inflated:
If the tires are inflated with too much pressure:
Too much wear can occur in the center of the tire treads.
-
The braking effect can decrease.
-
There is an increased risk of Foreign Object Damage (FOD) to the tires.
(3)
Tread wear (worn more than the maximum limit):
When the tire is worn until the reinforced material (metal or fabric), it is worn more than the maxim
um limit.
(4)
Tread rubber reversion (hydroplaning on wet or frozen surfaces):
You can see this condition when there is an oval area of damage on the tire tread. It is almost the s
ame as the skid damage, but the rubber shows burns.
(5)
Thrown tread:
This condition occurs when a part or all of tires tread decreases to the tread fabric ply.
(6)
Peeled rib:
This condition can start with a cut in the tread. This causes the tread rib to delaminate on the circu
mference.
(7)
Fabric fraying:
The fraying of the tread or the breaks are on the ply at the base of the tread groove.
(8)
Open tread splice:
This is a cut or an opening where the tread joint or splice separates radially on the treads.
(9)
Cuts:
These are cuts which extend more than 50% of a rib and 50% of the remaining groove depth.
(10) Tread flaking and chipping:
You can see this condition when the rubber particles come out of the tread.
(11) Tread broken (rib tear):
You can see this condition when the tire has a large side force applied during landing or taxiing.
(12) Chevron cut:
Cross grooves on the runway surfaces can cause chevron shaped cuts on the tire tread.

(13) Blister or bulges:
This is a separation or a bulge on the tread or the sidewall.
(14) Groove crack:
This is a crack at the bottom of the tread groove.
(15) Rib undercut:
These are the cracks or the undercut that occur below the tread rib.
(16) Circumferential or radial cracks:
These are the cracks in the sidewall of the shoulder area of the tire.
(17) Ozone and weather cracks:
These are the cracks caused because of weathering and ozone exposure.
(18) Skid and flat spot damage:
This is an oval wear pattern on the tread area.
(19) Contamination:
This is caused because of the brake oil, tar oil, solvent, chemicals and products made with hydrocar
bon.
Clean the tires with the Non Aqueous Cleaner-- Isopropyl Alcohol - (Material Ref. 08BBD1) and the
Aqueous Cleaner-Aircraft Exterior Pressure Spraying - (Material Ref. 08ABC1). After cleaning, push t
he rubber in the contaminated area.
If the rubber is tacky, replace the wheel.
WARNING: DO NOT REMOVE OBJECTS FROM A PRESSURIZED TIRE. THE PRESSURE CAN EJECT
THE OBJECTS WITH MUCH FORCE AND THUS CAUSE INJURY.
(20) FOD:
If the tire has a foreign object in the tread or the sidewall:
(a)
Make a mark around the foreign object with the MARKER - CHALK, STICK.
(b)
Deflate the wheel and tire assembly.
(c)
Remove the wheel and tire assembly.
(d)
Send the wheel and tire assembly to the shop.
(21) Circular tire movement on the wheel:
(a)
Paint a continuous radial line on the tire and the wheel when the tire is installed.
(b)
If the circular tire movement is less than 20 degrees after the first flight cycle:
1
Keep the wheel on the aircraft.
2
Monitor the circular tire movement for the next five flight cycles.
NOTE:
(c)
The circular tire movement is the total tire movement during the five flight cy
cles.
If the circular tire movement is more than 20 degrees after the five flight cycles:
1
Replace the wheel.
2
Send the tire to the tire shop for inspection.
(22) For the tires used at the maximum speed:
(a)
After a take off or landing at more than the maximum speed limit of 235 mph (204 kts):
1
Do the readout procedure of the Digital Flight Data Recorder (DFDR) and download the
wheel speed data Ref. AMM TASK 31-33-00-710-807.
