if the max recommend PSI for my car is 35 psi on 205/55/15 tires

car comes stock with 205/55/15 tires and I got new tires. Shop didn't have 205/55/15 so I went with falken ze912 205/60/15. Recommended max PSI on the door jam says 35psi for 205/55/15. Considering I have more sidewall with 205/60/15 how much can I increase the psi?

Reason i ask is because I used to ride at 30psi for a softer ride but when gas started going up I went with 35psi and I noticed a significant gain in mpg and my tires didn't wear out as fast. Now I try to set the tires towards the upper psi range for maximum mpg. BTW the max psi on the falkens are about 50psi but that is over the top and I would think it would be very bad for my shocks and struts.
 
you odometer will be off cause of the diffrent sized tires thats for sure. but to answer your questions stick with what you were running. normal sized tires should be 32psi roughly give or take 5 psi pending a lot of things.

The number on the sidewall is a structural limit for the tire, not a recommendation for actual use.

Use the number on the car's sticker to start with, then adjust the pressure within a +/- 5 PSI range to achieve the desired ride and handling characteristics.

Actuall you be off by 3.4%, so when your speedo reads 60 you will be going 62. The +/- sizes for your original tires would be either 215/50/15 or 195/60/15 but that's a moot point. If gas mileage is your concern I would only add 3-5 lbs more than stated on the sticker. Remember however, that the sticker pressure was recommended for the OEM tires only, not replacements.
