Why would you want to notch it up (or down) against manufacturer pressure recommendation? And how do you know it'll save you gas?

Noted. Sounds good! 35/34
Not really. Not sure why anyone play with tire pressure that was specifically designed for a specific car. Your gas savings are non-existing or minimal at best, but you'll shorten your tires' life and also compromise car stability and safety.
You won't "ruin" them per-se, but you will shorten their life. They are suppose to run with a calculated/designed pressure and if you over-inflate or under-infalte it shortens their life, it causes the car to be outside it's handling characteristics and you save no gas whatsoever.
That is, of course, assuming we are talking about normal road driving conditions, not off-road, extreme driving, racing, etc.
Yup, I never over or under inflate. I go by the book. Tires are your only contact with the road :thmsup:
Absolutely correct. It's proven. Did you see the PM link?
If it's incorrect, why would car manufacturer even bother posting tire pressure? Let the driver put whatever they want, right?

My coupe is 33/32! V6 auto. According to the sticker on the door anyway.
+1 for me also
You are wrong.
Over inflation decreases wear.
MPG savings when inflated higher can be significant, but could be at the expense of decreased traction, handling, and ride comfort- but not necessarily.
As others have stated, the manufacturer's recommendations are a balanced compromise between safety, ride comfort, handling, fuel economy, tire life, and traction. Over inflation or under inflation can change that balance based upon the driver's desires.
And even in each of the above categories(safety, handling, traction, tire life, mpg, ride comfort) changing pressure can have both negative and a positive factors in each category at the same time.
Additionally, the manufacturers recommendations are based on an averaged cargo load. Your tires and car will behave differently if you have, say, one small adult female driving the car with no passengers or cargo, vs 5 large adult males and a trunk full of luggage.
