Open driver door and look in the door well to your right....There is a label detailing tire pressure and weight limits for the vehicle.Mine it says 35lbs in front and 32 lbs in the rear though i have a AWD
a litle bit higher would probably get an improvement on gas mileage. mine arre set at 35. i drive 21 miles each way to work 6 days a week. my gas goes for 8 days @ 33mpg for the week.
