Tire pressure Make sure that the tire pressure for normal speeds is adopted again. Additional specifications of tire pressure values for loads can also be found on the tire pressure table on the inside of the fuel filler flap. Observe the following for the tire pressure on the spare wheel: Rthe 251 tire and loading information table on the B-pillar on the driver's side. Rthe tire pressure sticker on the inside of the fuel filler flap. Tire pressure table with tire sizes (example) Tire pressure too low or too high Underinflation G Warning Tire pressure table for all approved tires installed at the factory (example) If a tire size precedes a tire pressure, the tire pressure information following is only valid for that tire size. The load conditions "partially laden" and "fully laden" are defined in the table for different numbers of passengers and amounts of luggage. The actual number of seats may differ from this. Follow recommended tire inflation pressures. 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. Underinflated tires may: Rwear quickly and unevenly Rhave an adverse effect on fuel consumption Roverheat Rhave leading to tire defects an adverse effect on handling characteristics Z Wheels and tires i The specifications shown in the examples in the tire pressure tables are only examples. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. The tire pressure specifications that are valid for your vehicle can be found on your vehicle's tire pressure table. If no other data is stated, the tire pressures specified on the fuel filler flap apply for all tires approved for this vehicle. Some tire pressure tables only show the rim diameter instead of the complete tire size, e.g. R16. The rim diameter is part of the tire size and can be found on the tire sidewall (Y page 263).
