Land Rover Defender: Tire glossary
lbf/in² or psi: Pounds per square inch, an imperial unit of measure for pressure.
kPa: Kilopascal, a metric unit of measure for pressure.
Cold tire pressure: The air pressure in a tire which has been standing in excess of 3 hours, or driven for less than 1 mile.
Maximum permissible inflation pressure: The maximum pressure to which the tire should be inflated. The pressure is given on the tire's sidewall in lbf/in² (psi) and kPa.
Note: The pressure is the maximum allowed by the tire manufacturer, not the pressure recommended for use.
Curb weight: The weight of a standard vehicle, including:
- A full tank of fuel, if applicable.
- Any optional equipment fitted.
- The correct level of coolant and oils.
Accessory weight: The combined weight, in excess of those items replaced, of items available as factory fitted equipment.
Production options weight: The combined weight of options fitted which weigh in excess of 5 lbs (2.3 kg) more than the standard items that they replaced.
Note: Not to include items already considered in curb or accessory weights.
Such items include: heavy duty brakes, high capacity battery, special trim, etc.
Vehicle capacity weight: The number of seats multiplied by 150 lbs (68 kg), plus the rated amount of load and luggage.
Maximum loaded vehicle weight: The sum of the curb weight, accessory weight, vehicle capacity weight, plus any production option weights.
Rim: The metal support for a tire, or tire and tube, upon which the tire beads are seated.
Bead: The inner edge of a tire that is shaped to fit to the rim and form an airtight seal. The bead is constructed of steel wires which are wrapped, or reinforced, by the ply cords.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
The Tire Pressure Monitoring System
(TPMS) provides a low pressure warning
and does not re-inflate the tires. Tire
pressures should be checked regularly,

The vehicle's current tire pressures can be
displayed via the Vehicle and Tire
information menus.
When selected, the instrument panel
displays two tire pressure values for each
tire. One value shows t
