HEAT BURST
POSSIBLE CAUSES Abnormal heat generation may occur at the bead and shoulder areas. In the worst case, bursting may result.
Tire Damage
CHAFER DAMAGE
POSSIBLE CAUSES If the tire is mounted incorrectly on the rim or is mounted using a wrong tool, the tire beads may be damaged. Improper inflation of the tire and…
OVERHEATING FROM EXCESSIVE BRAKING
POSSIBLE CAUSES Excessive braking or maladjusted brakes are liable to create high heat build-up, which may lead to melting of the rubber at the bead seat or toe/heel areas. RECOMMENDATION…
CASING BREAK UP (CBU)
POSSIBLE CAUSES This phenomena are caused by under inflation and excessive taxi distances. RECOMMENDATION When swelling or bulges are detected at the lower sidewall, remove the tire and return to…
INNERLINER WRINKLING
POSSIBLE CAUSES Wrinkling of the innerliner typically occurs due to over deflection of the tire. This type of damage can also indicate that the tire has experienced low inflation pressure…
WEATHERING & RADIAL CRACKING
POSSIBLE CAUSES Weathering and radial cracking occur when tires are exposed to ozone or to direct sunlight (ultraviolet rays) for extended periods of time, and are accelerated by insufficient tire…
SIDEWALL CRACKING Circumferential cracks 2nd
POSSIBLE CAUSES Circumferential cracks are caused by load shear and stress combined with low tire inflation pressure. Cracking in the area where the tire touches the rim flange can occur…
SIDEWALL CRACKING Circumferential cracks
POSSIBLE CAUSES Circumferential cracks are caused by load shear and stress combined with low tire inflation pressure. Cracking in the area where the tire touches the rim flange can occur…
SIDEWALL CUTS
POSSIBLE CAUSES Sidewall cuts are often caused by foreign objects. RECOMMENDATION If sidewall cords are exposed or damaged, remove the tire from the aircraft.
BULGE/BLISTER
POSSIBLE CAUSES Bulges and blisters indicate a separation or damaged tire. RECOMMENDATION Mark the area and remove the tire immediately from the aircraft. Small bulge shall be also checked carefully.
SKID BURST
POSSIBLE CAUSES Skid bursts result from brake malfunctions or locking of the wheel, most often during landing. Without tire rotation, the rubber and carcass plies are quickly worn through leading…
IMPACT BREAK
POSSIBLE CAUSES For bias tires, FOD and shock bursts are typically identified by diamond or X-shaped ruptures of the tread and carcass sustained by rolling over foreign objects. The photograph…
