My dealer set the tire pressure of all 4 tires on my 2009 smart to the same number...any idea what this will do to the car since the recommended pressure for the front and back has a bigger gap?

Is the recommended tire pressure on the car the best possible MPG?

Are you currently running the stock wheels and tires? 

The factory settings are 29psi front and 36psi rear. 

Hope this helps a little!
