I recently noticed my 550 has 32 psi written as normal tire pressure on the inside of the gas tank lid. My tires were always pumped to 38-40 psi, because that's how it originally came. Which is correct? Should I deflate to 32 psi?

I am using 39 for front and rear at moment.

was told to use the info on the gas tank door. normal load says 35 front and 36 rear. this is on my 2017 GLS550

I am using 39 PSI in my 450 GLS, mainly for the extra suspension "spring" of the higher inflation pressures (i.e., firmer).

I am also getting 20 MPG on moderate trips in the city....
