How To Set Porsche Tire Pressure

Checking and setting your tire pressure is easy but often overlooked. However, they are crucial to maintaining your vehicle as low tire pressure can cause excessive tire wear, and use up more fuel while high tire pressure can result in poor braking, less traction, and risk of tire blowouts. By checking your tires and maintaining the right tire pressure, you can keep your Porsche driving as efficiently and safely as possible. To set your tire pressure, you would first need to check your tire pressure, here’s how.

How to Check Your Porsche’s Tire Pressure

You can check your Porsche’s tire pressure at home using a pressure gauge. The best time to check your tire pressure is in the morning before it has been driven as driving can heat the tires, producing an inaccurate reading. It is also essential to ensure that your Porsche is not exposed to direct sunlight before the check as it will appear overinflated as a result of the heat absorbed from the sun. Allow your tires to stabilize in the shade before checking for an accurate reading.

The typical tire pressure of a car should be 34 PSI and 39 PSI for the front and rear tires respectively. However, depending on the model of your car, the numbers can differ slightly. Check your owner’s manual for the exact PSI needed.

Simply remove the valve cap from one of your tires then press the pressure gauge on the valve stem so that the hissing sound cannot be heard anymore. The gauge will provide a reading. Write down the reading and repeat for all four tires.

How to Set Porsche Tire Pressure

Now that you’ve established the pressure of your tires, you can accurately set your tire pressure to accommodate different variables.

For Indoor to Outdoor Temperature Differences

During the winter you might need to change your tire pressures as there are significant differences between the conditions in which the pressures are set and in which they will be driven. The pressure must therefore be set 1 PSI higher for every 10 F difference in temperature.

For the Increase in Temperature in the Afternoon

Set your Porsche tires 2 PSI above the cold inflation recommendations.

For Driving at Speeds of 45mph or Less

When driving at speeds of 45mphs or less, the tire heat generated from driving will need to be considered in the setting of tire pressure. For such conditions, the tire pressure should be set to 4 PSI above the cold inflation recommendations as stated in the owner’s manual.

For Driving Extensively at Speeds Greater than 45mph

Likewise, the tire heat generated needs to be taken into consideration and the pressure of the tires will have to be set 6 PSi above the recommended cold inflation for the vehicle.
