Operation Tires and wheels 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. 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 (if available) 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 your vehicle is not equipped with the tire inflation pressure label on the inside of the fuel filler flap, contact an authorized Mercedes-Benz Center for proper tire inflation pressure. (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. You should wait until the tires are cold before adjusting the tire inflation pressure. Some vehicles may have supplemental tire inflation pressure information for vehicle loads less than the maximum loaded vehicle condition. If such information is provided, it can be found on the tire inflation pressure label located on the inside of the fuel filler flap (Y page 221). Tire inflation pressure changes by approximately 1.5 psi (0.1 bar) per 18‡ (10†) of air temperature change. Keep this in mind when checking tire inflation pressure where the temperature is different from the outside temperature. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.
