W221 Wheel Air Pressure **WITH PICTURES**

[mbenz1]

Hi Guys

Car: W221 S320 CDI 2008 SWB (genuine MB 18" wheels - 255 front and 275 rear)

I have noticed that the air pressure on two wheels is slightly low... I had a look at the air pressure values on the inner side of the fuel filler cap and they don't make any sense. I have attached a picture of those values and also the rear tyre spec so you guys can have a look.

On average, there are around 2-4 passengers in the car with no luggage (let's keep it @ 4 passengers on average then), so which air pressure values do I follow? Why do all the air pressure values correspond to luggage in the car?

All advice is greatly appreciated.

Thanks.

Either/or possibly?

The higher air pressures figures are for when:

The car is fully loaded with occupants and/or luggage

The car is driven mostly on Motorways (whether fully ladden or not)

You want a firmer and more sporty ride (whether fully ladden or not)



In addition, the higher pressures will improve mpg and reduce tyre wear.

So on balance the higher pressure figures are best, with the only penalty being a slightly bouncy ride when driving an empty car (bar the driver) around town.


I would go for 33 at the front and 36 at the rear (ignoring the 'over 130mph' figures).

Thanks. Yes by looking at those values I guessed 33 and 36 would be the correct pressures but wasn't sure about the luggage issue.

What do you mean by 'the higher air pressure figures'?
