268 Definitions for tires and loading accessories, the maximum load and the weight of the optional equipment installed at the factory. PSI (pounds per square inch) Standard unit of measurement for tire pressure. Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa is the equivalent of 1 psi. Another unit for tire pressure is bar. 100 kilopascal (kPa) is the equivalent of 1 bar. Aspect ratio Relationship between tire height and tire width in percent. Tire pressure Load index In addition to the load bearing index, the load index may also be imprinted on the sidewall of the tire. This specifies the load bearing capacity more precisely. This is pressure inside the tire applying an outward force to every square inch of the tire's surface. The tire pressure is specified in pounds per square inch (psi), in kilopascal (kPa) or in bar. The tire pressure should only be corrected when the tires are cold. For this, the vehicle must have been stationary for at least 3 hours or not have traveled more than 1.6 km (1 mile) in this time. Wheels and tires Curb weight The weight of a vehicle with standard equipment, including the maximum capacity of fuel, oil and coolant and also includes the air-conditioning system and optional equipment if these are installed on the vehicle, but does not include passengers or luggage. Tire tread The part of the tire that comes into contact with the road. Tire bead Maximum tire load The maximum tire load is the maximum permissible weight in kilograms or lbs for which a tire is approved. The tire bead ensures that the tire sits securely on the wheel. There are several steel wires in the bead to prevent the tire from coming loose from the wheel rim. Maximum permissible tire pressure Maximum permissible tire pressure for one tire. Sidewall The part of the tire between the tread and the tire bead. Maximum load on one tire Maximum load on one tire. This is calculated by dividing the maximum axle load of one axle by two. Weight of optional extras The combined weight of those optional extras that weigh more than the replaced standard part and more than 2.3 kg (5 lbs). These optional extras, such as high-performance
