Tyre pressures - what are you running?
Spurred on by my car moaning that the front tyre was low I checked my pressures.
2 bar in the front, and 2.1 in the back. That'll be a bit low then.
So, I dug out the manual (or rather open the app) and found the basic is 2.3 bar front and rear, or 2.7 front and 3.3 rear for fully loaded.
I compromised on 2.7 front and rear and reset the tyre pressure monitor to that. Ride doesn't seem to be any worse (thanks run-flats!) and I guess it'll save a couple of pennies on the fuel consumption but just wondered what others have set seeing as though, going by the manual, you can take these values and +/- 0.3 bar to them which is quite a range.

34 psi all around. Gas mileage is not impacted, handling is about the same, and the "thunk" over harsh pavement is less pronounced.

Just posted this in another thread about tire pressures and my experience.
My C300 came with 18 inch staggered runflats and has the same sticker under the gas flap. I ran the higher pressures although I rarely had a maximum load. Toward the end of the tires usable life, just under 20K miles, I noticed that the rears showed more wear in the center of the tires indicating the pressure was higher than it should be. I am now running non runflats and have lowered the rear pressures to 39-40 psi. Front tires did well at 39 psi.
