PSI For 2007 Ford Taurus SEL?

Question

Just picked this car up. Door panel says 30psi front and rear which has to be a joke for a car 3400lb car with 215s. What can I safely inflate them to? 34Psi? I know the 30psi is for cushioning but I'll take the better gas mileage and handling with a higher psi. Just don't know how high to go. Thanks.

Answer 1

Look at the tire itself it will have a max inflation stamped on it and go several pounds under for best mileage

Answer 2

Over-inflating your tires above what is recommended on the door sticker may give you better gas mileage, but your tires will wear faster and you will not get as good of a ride. The tire pressure on that sticker is based on the stock tire size and type for that vehicle and set by the engineers at Ford based on all kinds of information and calcs. NEVER runs your tires at max (based on what is stated on the side of the tire). That is the max pressure the tires can handle under "normal" driving conditions. One pothole and your tires are toast.



So in short....just follow what the manufacturer recommends and be done with it. And another good rule of thumb is to have the tires rotated at least every other oil change (5,000-10,000 miles)

Answer 3

It seems you know more than the engineers and tire experts and technicians that designed this vehicle and tested the design over and over and over. Using data gathered the recommendations and instructions were approved and installed on the vehicle. Since the recommended tire pressure is for cold tire temperatures you are not educated enough to know that normal operating temperatures of a tire is about 200 degrees F. That temperature brings the pressure in the tire to the best tire pressure for the chassis and suspension system. The operating PSI is several degrees higher perhaps in the five plus degree range. To overinflate a tire actually decreases handling and control and causes early wear on the tires. Please Google your heart"s content to locate information from experts using accredited automobile websites. The parameters studied were maximum g forces during high speed turns, stopping distances, wet and dry, cornering and aerodynamic stresses on the body at cruising speeds. Are you aware of all of these scientific testing parameters and results? I suggest you learn as the "tire contact patch" and kinetic energy and the right way to stop the car in a panic stop situation. In fact, to learn all of these items correctly you need to take an advanced driving course. Google "teen driving courses" for locations and prices in your area. I also suggest you read the owner's manual, cover to cover.

Answer 4

The tire pressure for your car is on a sticker located either on the driver's door jam or in the glove box. The maximum tire pressure on the tire is just that, the maximum pressure for that tire, depending on what vehicle it is on.

Answer 5

I usually go a few pounds under the design pressure of the tires, unless the vehicle is going to be used hard, and then I will go with the maximum pressure for the tires.

Answer 6

40 psi

Answer 7

Go with what the sticker says.

The number isn't for "cushioning".

It's actually for best handling and mileage combined.
