Officially, the tire manufacturers will tell you to use the figures on the inside of the door (29 psi, in your case). The figure on the tire is the maximum cold pressure for the tire.
However, you can adjust a bit up and down between these numbers to find the handling and ride best for you. Most of us driving 4th generation models run higher than the door says (32 psi in our case) but well below the tires (depends on the tire -- mine say 51 psi maximum).
Underinflating will cause heat build up and lower tire life. Overinflating will cause the tire to wear early, too.
