Does anyone know what the correct winter tire PSI should be on the 2010 C350 4matic? My all season tires were 18", 35psi front, 38psi rear.

I installed the 17", 225 pirello sottozero winter tire set on my car from a MB dealer.

I am trying to determine the correct pressure for this set? Is it the same 35, 38? I've asked a few delears, but keep getting different answers.

Maybe even if someone has a c350 4matic (2008 or later) with 17inch wheels, the psi should be similar.

Thanks!!!

Hi Luke,

And this is for the C350 4matic w/ 17 inch winter tires?
Just want to make sure, because that seems low, to my uninformed mind..

Luke@tirerack

that's the pressure Mercedes recommends for your car with 17's. Personally I like higher pressures as well but, the standard pressure recommendation is based on vehicle weight. Higher pressure will offer better steering response and handling but, sacrifice some ride quality. You could easily go up to 36 on all four corners for a crisper feel

The pressue you mention seems to be for the C300 lux, but i have the c350 4matic. I tried the 29, 33 and felt way too soft...Is there any specific info for the 2010/2008 C350 or C350 4matic with 17", 225, non-staggared tires? In terms of the recommended PSI?

but, you don't have to do what Mercedes says .... set it to what is most comfortable to you
