Porsche Boxster Tire Pressure

Porsche Boxster tire inflation pressures range around 29 to 37 psi based on the production year, trim and original equipment tire sizes.

It is vital to maintain proper tire inflation pressures for Porsche Boxster tires. Low tire pressure and underinflated tires can lead to uneven and excessive tire wear, poor handling and reduced fuel economy. High tire pressure and overinflated tires can result in reduced traction, poor braking and can even be a cause of a tire blowout. Check tire pressure regularly and maintain correct tire inflation for Porsche Boxster to enjoy a safe and comfortable drive, save money on gas and keep auto insurance premiums low.

Recommended tire pressure for Porsche Boxster is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find Porsche Boxster recommended tire pressure in owner's manual or on a tire placard on the side of driver's door or door jam. Porsche Boxster tire inflation will be listed in psi (pounds per square inch), bar or kPa (kilopascals). Keep in mind that tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not necessarily the recommended tire pressure for Porsche Boxster. Porsche Boxster may have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.

To check Porsche Boxster tire pressure you will need to know its recommended tire inflation and a tire pressure gauge. Check tire inflation when tires are "cold" and have not been driven for at least 3 hours. Adjust Porsche Boxster tire inflation to the recommended tire pressure levels as needed by adding air with a tire inflator.

If you replace Porsche Boxster original equipment tires with optional or plus tire sizes, make sure to follow guidelines on how to apply tire load inflation tables when replacing Porsche Boxster tires to find proper tire pressure for new tires. Always refer to the Porsche Boxster owner’s manual for any specific safety advice regarding the application of replacement tires.

Porsche Boxster tire pressure fluctuates with ambient temperatures, so when temperatures drop tires may lose approximately 1 psi of air pressure for every 10 degree Fahrenheit decrease in temperature. During winter Porsche Boxster tires can be inflated 3 to 5 psi above the recommended tire pressure settings to compensate for lower temperatures. Never overinflate above psi 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. Consult owner's manual for recommended winter tire pressure for Porsche Boxster.

If your Porsche Boxster is made after 2007, it should be equipped with tire pressure monitoring system (TPMS) that uses tire pressure sensors to alert the driver when tire pressure is low. When Porsche Boxster low tire pressure warning light is on, check all tires for low air pressure and inflate as needed. Refer to owner's manual on how to reset Porsche Boxster tire pressure monitoring system.

Select model year between 1997 and 2016 to find recommended tire pressure for Porsche Boxster tires to improve fuel efficiency, extend tire life and drive safely.
