and the tire pressure is according to the weight of the driver
or the ignorance of the owner manual

 

I run mine at 40psi and have never had a problem, my tires wear just fine....and no issues with the car in wet or dry weather.....haven't had the car long enough to try it out in the snow......probably drop it down to 37, maybe lower depending on the conditions...I've always run my pressures pretty high with no ill effects.....oh well to each his own

 

I have 17" Pirelli Euforia runflat tires. I saw 38 psi on the door jamb sticker and set mine to that. Very soon afterwards, my front tires were worn out in the middle of the tread. I dropped to 32 psi and have had nice even tire wear ever since.

38 is kinda high 32 is kind of low. how about 34?

 

My dealer actually told me to inflate to 35 psi also, even though the door says 32 psi... So that is what i do!

 

I usually set mine at 33. Why... I don't know, it sounded like a good number.

 

Could it be the caffine fix to bipolar disorder in action? Works like this, ---consume enough coffee to remain in a perpetual state of manic excitement. Sentence structure invariably suffers as a result.
