Land Rover Discovery Owners & Service Manuals

Land Rover Discovery: Replacement tyres

  • Always fit replacement tyres of the same type, and wherever possible, of the same make and tread pattern. Failure to fit the same type, make and tread pattern may reduce vehicle stability.
  • The load and speed index ratings on all replacement tyres must be, at least, the same specification as the vehicle's original equipment.

    If in doubt, consult a Retailer/ Authorised Repairer.

  • If lower speed rated specialist tyres are fitted (e.g., winter tyres or off-road tyres), the vehicle must be driven within the speed limitations of the tyres. Consult a Retailer/Authorised Repairer for further information. In markets that require a tyre's maximum speed label to be fitted, the tyre's maximum speed label should be placed within the driver's field of vision. These can be obtained from the tyre retailer.
  • Do not rotate the tyres around the vehicle.
  • If the use of tyres not recommended by the vehicle manufacturer is unavoidable, make sure you read, and fully comply with, the tyre manufacturer's instructions.

Tyre removal and fitting should be carried out by a Retailer/Authorised Repairer.

When removing a tyre from a wheel or fitting a tyre to a wheel, make sure the Tyre Pressure Monitoring System (TPMS) sensor is not damaged.

When the tread has worn down to approximately 2 mm, wear indicators start to appear at the surface of the tread pattern. This produces a continuous band of rubber across the tread, as a visual reminder.

Tyres should be renewed in sets of 4. If this is not possible, renew the tyres in pairs (both front or both rear). When tyres are replaced, the wheels should always be rebalanced and the alignment checked.

Alternatively, contact a Retailer/Authorised Repairer for advice.

Replacement TPMS sensor

If a new TPMS sensor is to be fitted to a standard size running wheel on the vehicle, it should be installed by a Retailer/ Authorised Repairer. The vehicle needs to be stationary for 15 minutes during the sensor fitment, before the system is ready to detect the new sensor. The vehicle must be driven for a minimum of 15 minutes after the sensor change, and then remain stationary for 15 minutes to activate full TPMS operation.

If the TPMS warning lamp does not extinguish, even after checking the tyre pressures and driving for more than ten minutes above 25 km/h (16 mph), seek qualified assistance as soon as possible.

AVOIDING FLAT SPOTS

In areas of extended high ambient temperature, vehicle tyres can be affected by a softening of the tyre's sidewall. If the vehicle is stationary for long periods, the effect is to slightly deform the tyre at the point where the tyre meets the standing surface. This is known as a flat spot.

This is normal tyre behaviour. However, when the vehicle is subsequently driven, vibration may be experienced from the flat spot. The condition will steadily improve with extra mileage.

In order to minimise flat spotting while the vehicle is stationary for a long period, tyre pressures can be increased to the maximum, as stated on the tyre's sidewall.

The tyres must be returned to the specified running pressures before driving.

TYRE DEGRADATION

Tyres will degrade over time, due to the effects of ultraviolet light, extreme temperatures, high loads, and environmental conditions. It is recommended that tyres are replaced at least every 6 years from the date of manufacture, but they may require replacement more frequently
