Drivers side door says 30lbs/front and 35lbs/rear for my stock 17's. The front seems a bit low to me. I think I'm going to run 32lbs in the front and 35lbs in the rear.

Just curious as to what others are running.

I just put the recommened tired pressure. Cant go wrong with that

C300Sport

I have always run a couple PSI above recommended and have never had an issue. I figure a couple extra PSI will insure a solid feel and good economy.

35 all around .... i'm thinking of running @ 37 .. for improved gas mileage..

I think it is supposed to be 32 or 35... check the door on the fuel flap to be sure.

It specifically states less for the front, more for the rear, and +5 if going over 100+ mph, so add 5.

I actually take the time to check my pressures monthly despite my nice nails
but according to the door jamb is says 30 front and 35 rear respectively so i usually go a little more at 31 and 36/37 !!

I learned to do this when the MB caps i got off ebay got stuck on the TPMS valve stems due to the crud and road salt soo now it forces me to twist these open monthly and won't get stuck

So...I picked up my 2009 C300 Sport on Friday and by the time I got home, I had the "check tire pressure" warning. Saturday morning I checked the tires and the fronts were at the "correct" pressure of 33 and the rears were at the "correct" pressure of 38. I upped the rears to 40 and the fronts to 38. No warning today!

P.S. I have the 18" AMG dual spoke rims.
