Which Tire Pressure?

Help settle an argument.

I use 32psi in my standard 205/65 15 Toyo Spectrums in my 300SE. A friend, and M-B enthusiast, said that I should stick to the M-B recommended 26psi.

The tires just don't look right at the lower psi. Ride quality is just fine at 32psi.

Any opinions?

You will get as many answers as people. I run 35 myself. It does not really matter. Less pressure a softer ride but more wear. More pressure will be a harder ride but less wear. Then too soft is dangerous and too hard is dangerous. Anything in between is up to you.https://mbworld.org/forums/images/smilies/biggrin.gif

Stick to the pressures indicated on the inside of the fuel filler cap or in the car's handbook. Departing from manufacturer's specifications on a safety-critical component seems to me to be unwise. The appearance doesn't seem relevant.

26 psi is not what is specified for my 300SE.

On my 560SEC 26 is specified front and rear, then +9 PSI for high speed driving (which I usually do).
