If I recall correctly oem specs for the 205/55 16s is 30psi front and 28 rear unless you are carrying a full load and/or doing highspeed driving then its 30psi front and 32 rear.


On TDis I think its 36 and 36... or something like that. I guess for improved economy.

I run 35 and 35 on my 225/40 18s and 36 and 36 on my 205/55 16 snow tires...

Ohh, I have the same question. I have Turbo S so tire size is 17/225-45. I looked under the gas tank door but I don't undersand what it's saying, it seems that it shows same psi for all sizes. I just put 36 on all of them but I think that's a little too much.

Ok... according to www.tirerack.com 32psi for 225/45 17 and 225/40 18s should be pretty much an ideal compromise for handeling, longevity, fuel milage and rim protection (filled on a 70* day). That way you do not risk over inflation on 110* summer days and still have enough pressure for temps down to 30*

If you are running snow tires you should increase that by 5lbs due to the softer sidewalls and to compensate for the 1psi drop in pressure for every 10*F. So if you fill your tire at 60*F the tires will still have 30psi at -10*F and not be over inflated on those occasional 70* early spring and late fall days.
