Tires and wheels data shown in the following illustration. Refer to Tire and Loading Information placard on vehicle for actual data specific to your vehicle. 235 The Tire and Loading Information placard lists the recommended cold tire inflation pressures : for maximum loaded vehicle weight. The tire inflation pressures listed apply to the tires installed as original equipment. Important notes on tire inflation pressure G Warning! If the tire inflation pressure drops repeatedly, check the tires for punctures from foreign objects and/or whether air is leaking from the valves or from around the rim. i Driving comfort may be reduced when the tire inflation pressure is adjusted to the value for speeds above 100 mph (160 km/h) as specified on the tire inflation pressure label located on the inside of the fuel filler flap. Make sure to readjust the tire inflation pressure for normal driving speeds. Supplemental tire inflation pressure information for different loading conditions of the vehicle can be found on the tire inflation pressure label. The tire inflation pressure label is located on the inside of the fuel filler flap. For the tire inflation pressure for spare wheels such as Minispare wheels or spare wheels with collapsible tire refer to Rthe yellow label on the spare wheel rim Rthe "Technical data" section of this Operator's Manual (Y page 368) Rthe Tire and Loading Information placard on the driver's door B-pillar Unless specified otherwise, the tire inflation pressures on the tire inflation pressure label are valid for all approved, factory-equipped tires. i Data shown on tire inflation pressure label examples are for illustration purposes only. Tire inflation pressure data are specific to each vehicle and may vary from data shown in the following illustrations. Refer to the tire inflation pressure label on vehicle for actual data specific to your vehicle. Tire temperature and tire inflation pressure are also increased while driving, depending on the driving speed and the tire load. If you will be driving your vehicle at high speeds of 100 mph (160 km/h) or higher, where it is legal and conditions allow, consult the tire inflation pressure label on the inside of the fuel filler flap on how to adjust the cold tire inflation pressure. If you do not adjust the tire inflation pressure, excessive heat can build up and result in sudden tire failure. If you are not sure about the proper tire inflation pressure, contact an authorized Mercedes-Benz Center. Z Operation
