Porsche 911 Recommended Tire Pressure

Check Porsche 911 tire pressure charts with recommended tire inflation pressures for Porsche 911 tires to improve fuel efficiency, extend tire life and drive safely. Select your Porsche 911 year.

It is vital to maintain proper tire inflation pressures for Porsche 911 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 911 tire pressure regularly, and monitor Porsche 911 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 911. Use Porsche 911 recommended tire pressure settings listed on the tire pressure chart found in Porsche 911 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 911 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 911 may have different recommended tire inflation pressures for front and rear tires, especially if equipped with staggered tires. Keep your Porsche 911 tires inflated at recommended tire inflation pressures at all times for your driving comfort and safety.

If you replace Porsche 911 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 911 tires. Porsche 911 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 911 replacement tires must have equal or greater speed rating compared to the original equipment tires if your Porsche 911 speed capability is to be maintained. It is recommended that tire installers refer to the Porsche 911 owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your Porsche 911 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 911 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 911 manual to find its original equipment tire sizes and load ratings. Always refer to the Porsche 911 owner’s manual for any specific safety advice regarding the application of Porsche 911 replacement tires.

Porsche 911 tire pressure may fluctuate with ambient temperatures, so check Porsche 911 tire pressure when ambient temperatures change. In winter when temperatures drop, Porsche 911 tires may deflate by approximately 1 psi for each 10 degree Fahrenheit decrease in temperature. Maintain proper Porsche 911 winter tire pressure by adding air to your tires as needed to the recommended tire inflation levels.

Porsche 911 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 911 is equipped with tire pressure monitoring system (TPMS), pay attention to low tire pressure warning light being on. Ensure Porsche 911 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 911?
Recommended tire pressure for Porsche 911 is determined by the manufacturer based on your vehicle's characteristics and original equipment tire sizes. Select your Porsche 911 year to get recommended tire inflation pressures for Porsche 911 tires.

Where do I find recommended tire pressure settings for Porsche 911?
You can find your Porsche 911 recommended tire pressure in Porsche 911 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 911 will be listed in psi, bar or kPa.

How to check Porsche 911 tire pressure?
Proper Porsche 911 tire inflation is essential to the overall tire performance and safety. To check tire pressure for Porsche 911 you will need to know its recommended tire pressure and a tire pressure gauge. Check cold inflation pressures in Porsche 911 tires with tire pressure gauge and adjust to Porsche 911 recommended tire inflation pressures as needed by adding or releasing air. Make sure to check tire inflation for your Porsche 911 regularly to ensure safe and comfortable drive.

Why is Porsche 911 tire pressure warning light on?
If your Porsche 911 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 911 low tire pressure warning light is on, check all Porsche 911 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 911 tire pressure monitoring system?
To reset tire pressure monitoring system for Porsche 911, make sure front and rear tires are inflated to the recommended levels. Refer to your owner's manual on how to reset Porsche 911 TPMS.

What is recommended winter tire pressure for Porsche 911?
Recommended tire pressure for Porsche 911 is the same for any season, but you may inflate your Porsche 911 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 911 tire pressure more often in the winter to keep tires properly inflated for a safe ride on snow and icy roads.
