Signs of tire failure (Defender 2007+)

• Check the tire pressure. For more information, refer to the chapter: Specifications (204-04 Wheels and Tyres, Specifications).
• Check the condition of the tires.
• Check the front wheel alignment angles. For more information, refer to the chapter: Front Wheel Alignment (204-00 Suspension - General Information, General Procedures).
• Check wheel balancing.

NOTE: When any obvious vibration is not eliminated at this stage.

NOTE: When any obvious vibration is not eliminated at this stage, go to the section " Diagnostics of steering malfunctions, Signs of malfunction (vibration in steering, angular oscillation of steering wheels)".

For more information, refer to the chapter: Steering system (211-00 Steering system - General information, Diagnostics and tests).

NOTE: Radial tires have elastic sidewalls that bulge, causing the tire to appear underinflated. This is a normal condition for radial tires. Do not attempt to reduce this bulge by inflating the tire to higher pressures.

Pos.	Spare part number	Name
1.	-	Correct tire pressure.
2.	-	Insufficient tire pressure
3.	-	Excessive tire pressure.
4.	-	Contact of the tread with the road.

Tire Tread Wear Chart

CAUTION: This chart is intended as a general guide only and does not necessarily include all causes of abnormal tread wear.

Malfunction	Cause	Method of elimination
Rapid wear of tire shoulders	Insufficient tire pressure	Inflate the tire to the correct pressure
	Worn suspension components such as ball joints, diagonal rod bushings, steering damper	Replace worn out parts
Rapid wear in the center of the tread	High tire pressure	Inflate the tire to the correct pressure
Wear of one shoulder of the tire	The track alignment is broken	Adjust the track to normal.
	The diagonal bar is deformed (panhard bar)	Check and replace worn or damaged components
"Bald" spots or "cupping" of the tire	Wheel imbalance	Balance the wheel and tire assembly
	Increased radial runout	Check the runout and replace the tire if necessary
	The shock absorber is worn out	Replace the shock absorber
	Excessive braking
Protruding areas on the tire profile	The track alignment is out of adjustment	Adjust the track to normal.
	Wear of suspension components	Check and replace worn or damaged parts and replace the tire
	High speed cornering
