It is vital to maintain proper tire inflation pressures for Porsche tires. Low tire pressure will result in tire underinflation while high tire pressure will result in tire overinflation, which can reduce fuel efficiency, lead to uneven tire tread wear and decrease tire life, compromise tire safety and cause tire blowout. Check Porsche tire pressure regularly, and monitor Porsche tire inflation pressures to avoid driving with overinflated or underinflated tires.
Tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not the recommended tire pressure for Porsche. Use Porsche recommended tire pressure settings listed on the tire pressure chart found in Porsche owner's manual, on a tire placard on driver's door or door jam, inner trunk lid, in the console or on the fuel door. Recommended tire pressure for your Porsche tire sizes will be listed in one of the following pressure units: psi (pounds per square inch), bar or kPa (kiloPascals). Pay attention as your Porsche may have different recommended tire inflation pressures for front and rear tires, especially if equipped with staggered tires. Keep your Porsche tires inflated at recommended tire inflation pressures at all times for your driving comfort and safety.
If you replace Porsche original equipment tires or switch to plus size tires, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for your new Porsche tires. Porsche tires with the same load index, regardless of tire size, may carry the same load, but may require substantially different inflation pressures. Tire load index may not be used independently to determine replacement tire acceptability for load capacity. An equal or greater load index does not always correspond to equal or greater load capacity at all inflation pressure settings. Porsche replacement tires must have equal or greater speed rating compared to the original equipment tires if your Porsche speed capability is to be maintained. It is recommended that tire installers refer to the Porsche owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your Porsche replacement tires have a lower speed rating than the original equipment tires, your vehicle’s speed must be restricted to that of the replacement tires. Original equipment tires that come on your Porsche will have the proper tire load index, so use same or higher load index when choosing replacement tires. Tire load index tells you how much weight your tire can carry. Putting too much weight on your tires will overload them, and can cause premature tire wear, tire damage or even tire blowout. Refer to your Porsche manual to find its original equipment tire sizes and load ratings. Always refer to the Porsche owner’s manual for any specific safety advice regarding the application of Porsche replacement tires.
Porsche tire pressure may fluctuate with ambient temperatures, so check Porsche tire pressure when ambient temperatures change. In winter when temperatures drop, Porsche tires may deflate by approximately 1 psi for each 10 degree Fahrenheit decrease in temperature. Maintain proper Porsche winter tire pressure by adding air to your tires as needed to the recommended tire inflation levels.
Porsche tire pressure should be checked when tires are cold, after your vehicle has not been driven for at least three hours. It is best to check your tire inflation pressure in the morning, after the vehicle has been parked overnight, using a reliable tire pressure gauge.
If your Porsche is equipped with tire pressure monitoring system (TPMS), pay attention to low tire pressure warning light being on. Ensure Porsche tire pressure sensors are working properly to stay alert and enjoy a safe ride. If your tire pressure warning light is on, check front and rear tires to make sure they are properly inflated.
What is the recommended tire pressure for Porsche?
Recommended tire pressure for Porsche is determined by the manufacturer based on your vehicle's characteristics and original equipment tire sizes. Select your Porsche year or model to get recommended tire inflation pressures for Porsche tires.
Where do I find recommended tire inflation pressures for Porsche?
You can find your Porsche recommended tire pressure in Porsche owner's manual, on a tire placard on driver's door or door jam, inner trunk lid, in the console or on the fuel door. Recommended tire pressure for Porsche will be listed in psi, bar or kPa.
How to check Porsche tire pressure?
Proper Porsche tire inflation is essential to the overall tire performance and safety. To check tire pressure for Porsche you will need to know its recommended tire pressure and a tire pressure gauge. Check cold inflation pressures in Porsche tires with tire pressure gauge and adjust to Porsche recommended tire inflation pressures as needed by adding or releasing air. Make sure to check tire inflation for your Porsche regularly to ensure safe and comfortable drive.
Is my Porsche equipped with a tire pressure monitoring system (TPMS)?
If your Porsche is made after 2007, it should be equipped with tire pressure monitoring system. To confirm if your Porsche has TPMS, turn on the ignition without starting the engine. If a tire icon with an exclamation sign lights up on your dashboard, your Porsche is equipped with TPMS. You can also check Porsche owner's manual for more information.
Why is Porsche tire pressure warning light on?
If your Porsche is equipped with Tire Pressure Monitoring System (TPMS) it will alert you when tire pressure is too low and your tires could be underinflated, which can lead to uneven tire wear or can cause tire failure. If Porsche low tire pressure warning light is on, check all Porsche tires for low air pressure and inflate tires to the recommended tire inflation pressures. Keep in mind that Tire Pressure Monitoring System does not replace routine tire pressure check and maintenance.
How do I reset Porsche tire pressure monitoring system?
To reset tire pressure monitoring system for Porsche, make sure front and rear tires are inflated to the recommended levels. Refer to your owner's manual on how to reset Porsche TPMS.
What is recommended winter tire pressure for Porsche?
Recommended tire pressure for Porsche is the same for any season, but you may inflate your Porsche tires 3 to 5 psi above the recommended tire pressure set by the manufacturer to compensate for lower temperatures during winter. Make sure to check your Porsche tire pressure more often in the winter to keep tires properly inflated for a safe ride on snow and icy roads.
