Tire wear classification table (Discovery 1)

Wear	Cause
Rapid wear of the outer tracks	Insufficient tire pressure Wear of suspension components such as ball joints, tie rod bushings or steering shock absorbers Increased cornering speed
Rapid wear of the central tracks	Overinflation of tires
Wear of one outer track	Incorrect adjustment of the steering rod Bent Panhard rod
Wear spots	The wheel is not balanced Increased radial runout of the disc Shock absorber defect Frequent abrupt braking
Scalping	Incorrect adjustment of the steering rod (wheel alignment) Wear of suspension parts Increased cornering speed

Check your tires weekly, more often if you drive regularly in off-road conditions. The tire tread has wear indicators:





When the tread depth decreases below the permissible value (1.6 mm), the wear indicator becomes a bridge between the tread pattern blocks:



Checking tire pressure is only done when the tires are cold, i.e. no earlier than three hours after the end of the trip. Check the pressure in all tires, including the spare.
