Tire pressure for S550/W221 with 20" wheels
I have a 2008 S550 with AMG sports package. What should I keep my tire pressure at? Can't seem to get a good answer from the MB techs - each one seems to give me a different answer:
Front: 255/35 R20
Rear: 275/35 R20
Tires: Continental "SportContact2" Z-rated
Front: 255/35 R20
Rear: 275/35 R20
Tires: Continental "SportContact2" Z-rated

I looked at an S63 the other day it says that the front needs to be at 42 and the rear at 44!!
. The S63 comes with stock 20" wheels BTW....
I have mine at 35.
Also, does anbody know how quickly these tires lose air? Mine seems to lose about 2-3 PSI per month
