Land Rover Defender: Replacement tires

Make sure the following warnings and notices have been read and fully understood. Failure to comply with the safety instructions could result in damage to the vehicle, or an accident, leading to serious injury or death.

Always fit replacement tires of the same type and, wherever possible, of the same make and tread pattern as the original. Failure to comply may reduce vehicle stability, efficiency, and range.

The load index and speed ratings on all replacement tires must be at least the same specification as the vehicle's original equipment. If in doubt, consult a retailer/authorized repairer.

If the use of tires not recommended by the vehicle manufacturer is unavoidable make sure to read and fully comply with, the tire manufacturer's instructions.

Failure to do so may lead to tire failure due to incorrect fitting or use.

Drive within the speed limitations for the tires if lower speed-rated tires are fitted, e.g., winter tires, off-road, or Professional Off-Road (POR) tires. In markets that require a tire's maximum speed label to be fitted, the label should be placed within the driver's field of vision. Tire maximum speed labels can be obtained from the tire retailer.

Consult a retailer/authorized repairer for further information.

Tire removal and fitting should only be carried out by a retailer/authorized repairer.

Make sure that the Tire Pressure Monitoring System (TPMS) sensor is not damaged during a tire change.

When the tread has worn down to approximately 0.07 in (2 mm), wear indicators start to appear at the surface of the tread pattern. Wear indicators produce a continuous band of rubber across the tread, as a visual reminder.

It is recommended that tires should be replaced in sets of four. If this is not possible, replace the tires in pairs, both front or both rear. When tires are replaced, the wheels should always be re-balanced and the alignment checked.

Use the correct tire specification and pressures. Alternatively, contact a retailer/ authorized repairer for advice.

PRESSURE COMPENSATION FOR AMBIENT TEMPERATURE CHANGES

Daily ambient temperature variations may cause intermittent, minor tire pressure changes, which is normal and should not indicate a tire failure.

To mitigate this condition, check and adjust the tire pressures to the recommended cold inflation pressures before vehicle use.

Note: Make sure that the correct tire pressures are maintained when moving to areas of differing ambient temperature.

AVOIDING FLAT SPOTS

In areas of extended high ambient temperature, vehicle tires can be affected by a softening of the tire's sidewall. If the vehicle is stationary for long periods, the tire deforms at the point where the standing surface meets the tire.

The tire deformation described is known as a flat spot and is normal tire behavior.

When the vehicle is subsequently driven, a vibration may be experienced from the flat spot. The condition steadily improves with extra mileage.

In order to minimize flat spotting, increase the tire pressures to the maximum, as stated on the tire's sidewall. The tires must be returned to the specified running pressures before driving.

TIRE DEGRADATION

Tires degrade over time, due to the effects of ultraviolet light, extreme temperatures, high loads, and environmental conditions.

It is recommended that all tires, including the spare, are replaced at least every 6 years from the date of manufacture.

However, the tires may require replacement more frequently.
