### What is the correct tire pressure for Porsche Boxster?

Recommended tire pressure for Porsche Boxster tires is 29 psi to 37 psi, set by Porsche manufacturer and based on model's original equipment tire size to optimize vehicle performance, fuel efficiency and safety.

### Where do I find the recommended tire pressure for Porsche Boxster?

Porsche Boxster recommended tire pressure can be found in owner's manual, on a tire placard on the side of driver's door or door jam, on the trunk lid, in the console or on the fuel door. Tire inflation will be listed in psi (pounds per square inch), bar or kPa (kilopascals).

### How to check Porsche Boxster tire pressure?

To check Porsche Boxster tire pressure you will first need to determine its recommended tire pressure for the front and rear tires. Take off tire valve caps and use a tire pressure gauge to check tire inflation in every tire. Adjust Porsche Boxster tire pressure to its recommended levels. If overinflated, let some air out by pressing down the center plunger in the valve stem. If underinflated, add air with tire inflator. Recheck tire pressure to make sure all tires are properly inflated. Replace the valve stem caps. Make sure to check tire pressure when tires are "cold" and have not been driven for at least 3 hours. Remember that the front and rear tire pressures may differ.

### What is proper tire pressure for Porsche Boxster replacement tires?

If you replace Porsche Boxster original equipment tires with non-stock tires that have different size or load capacity, new tires may require substantially different inflation pressures. Use our Replacement Tire Pressure Calculator to find proper tire inflation when switching to a different tire size.

### What is optimal winter tire pressure for Porsche Boxster?

Tire pressure fluctuates with ambient temperatures. When temperatures drop, Porsche Boxster tires may lose approximately 1 psi of air pressure for every 10 degree Fahrenheit decrease. During winter Porsche Boxster tires can be inflated 3 to 5 psi above the recommended tire pressure settings to compensate for lower temperatures. Do not overinflate above the maximum tire inflation pressure value indicated on tire sidewall. Make sure to check tire pressure regularly in the winter to keep tires properly inflated for a safe ride on snow and icy roads.

### Is my Porsche Boxster equipped with Tire Pressure Monitoring System (TPMS)?

If your Porsche Boxster is built after 2007, it is most likely equipped with a Tire Pressure Monitoring System. Check owner's manual to see if your model has TPMS.

### Why is my Porsche Boxster TPMS warning light on?

If Porsche Boxster TPMS warning light comes on and stays on, it means at least one of the tires is underinflated. If TPMS warning light goes on and off, fluctuating ambient temperatures may be the reason. If Porsche Boxster TPMS warning light flashes for 90 seconds when you start the vehicle and then remains illuminated, the TPMS is not functioning properly and you should have it serviced.

### How to reset Porsche Boxster Tire Pressure Monitoring System?

To reset TPMS on Porsche Boxster, follow the instructions in owner's manual. If TPMS will not reset, there may be a problem with tire pressure sensors.
