Why would you want to notch it up (or down) against manufacturer pressure recommendation? And how do you know it'll save you gas?I know that the recommended tire pressure for the Sport Sedan is 33 front and 32 back, but is it ok to notch it up by 1 on all 4s? I know it will help with the fuel economy.
What do you guys normally put in?
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.so if I pump them up a few psi I will ruin my tires? What have you based this conclusion on?
You are wrong.
