I just put 205/55/16 tires on my 1980 300cd. What would be the best air pressure for these tires. I have 32 in front and 34 in the rear right now. I just don't want to damage my tires. thanks andy.

For routine and normal loads, this would be fine.

I have a 225/45-17" on my 300E-24. I am still using the recommended tire pressure 35 Front 36 rear. OEM was 195/65-15. Is this ok?

SH - Logically it follows that the pressure ought to correspond to the original specs for optimum spec. It should be fine unless others have a different opinion.

32 front 34 rear is what I run on my 81 Sd with Michilen
