Tread

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.

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…

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…

POSSIBLE CAUSES When rubber gauge in the tread groove is thin, the reinforcing fabric pattern may become visible at the base of the groove. Tires with this condition are airworthy.…

POSSIBLE CAUSES Rib tearing occurs when a tire is subjected to an extraordinary side force during landing or taxiing. RECOMMENDATION If cords are exposed, remove the tire from the aircraft.

PHENOMENON Relatively smaller “gauges” occur on tread surface. Small amount of tread rubber is missing. POSSIBLE CAUSES Quite strong Lateral-Force is applied on the tread surface during operation. Typical maneuver…

POSSIBLE CAUSES Denotes a tire defect where the tread joint or splice separates in a radial direction during operation. RECOMMENDATION Tires having this defect must be removed from the aircraft.

POSSIBLE CAUSES Brake oil, fuel, tar oil, solvent, chemicals and hydrocarbons deteriorate tire rubber. RECOMMENDATION Clean the tire quickly with commercially available denatured alcohol to remove such substances, then wash…

POSSIBLE CAUSES Groove cracking may result from environmental aggression of the rubber (ozone attack for example) or from an excessive mechanical solicitation, insufficient inflation of the tire. These cracks occur…

POSSIBLE CAUSES Severe operating conditions may cause local reinforcing fabric nylon cord to rupture. When such tires are deflated, small bulges (i.e. surface swelling) may appear on the tread surface.…

POSSIBLE CAUSES This condition occurs when a tread rib partially or totally peels off in a circumferential direction. Usually beginning with a cut in the tread, it results in a…

PHENOMENON Superficial rubber cuts happen on the tread. The cuts are shaped as “v” and extend across the tread. POSSIBLE CAUSES This phenomenon usually occurs on grooved runways at aircraft…
