.......I read somewhere that the tire pressure recommended by the manufacture of all German cars are made for the event of high speed Autobahn driving. It was re comended to lower the tire pressure by two or three ponds for our more sedate cruising considering our speed limits.
Hm...,
If I understand that correctly it is the other way around.
Recommended sticker tire pressure numbers indicate the pressure you should use everyday.
For fast autobahn (& highway) touring the pressure should be increased by ... 0.2 bar (= x PSi) or so. This info is on the sticker.
But the real question I do not understand is the following:
Why (the heck) should the pressure in the front tires be lower than in the rear tires, by 0.4 bar (see Naj's sticker)??
I am not aware of any modern tire pressure recommendation that reflects the same as on these old MB stickers; neither for front wheel drive nor for rear wheel drive.
My factory original 114015 stroke eight tire sticker recommends the same pressure for front and back tires and the car is only half a year younger than the latest 280SL/8.
I myself keep the tire pressure identical, front & back. Mostly a bit more than recommended (2.4 bar(s) each) and it is a good ride with that. I do not have problems with any accelerated tire wear.
