Mein Auto:
I'm very curious to hear myself, mine are 300 miles new and I've been experimenting but only on my commute miles. Soon as I hit 400 miles, I'll take it on the twisties and report back.

MAX PSI is 40.

At 38R 35F:
Stiff, quiet, super grip (compared to the stock Conti's) and some tramlining (new tires usually will)

At 32.5R 32.5F (this is what the tire tech set them at)
Quiet, not as much tramlining, slightly less responsive.

I'm going to set them to 35 and 33 for a compromise tonight.

I have 235/40/17 all around. I run 38 psi cold all around and am happy. At 35 all around tramlining was worse, and the sidewall didn't seem as stiff. Only two data points thus far.

Hey guys! The Tire Rack recommends using factory inflation pressure when running stock sizes for standard street driving, but a few have had better luck with a couple psi higher. Just be aware that these pressures should be taken when the tire is 'cold', preferably in the morning.

Gary,
When you say "factory inflation pressure" are you referring to the placard stating recommended tire pressures on car? I have Yokohma AVS ES 100s 235/45-17s all around on my 530i sport; this is the stock size for the car. The recommeded pressures for my car when not maximally loaded are 29/33, which seems somewhat low from what I have been reading. Any suggestions/comments?

Thanks, Kevin

Yes, its strictly based on load and maintaining even wear. As most of you know, you can use more pressure for more responsiveness, just be aware the center of the tire will tend to wear more quickly. I run my tires about 3/4psi higher, I feel its worth the tradeoff in wear for a little better handling
