Tire Pressure Tips
  • Recommended tire pressure for 2014 Porsche 911 Targa 4S tires can be found in vehicle owner’s manual, on sticker placard on driver's door jam, inside glove box compartment or fuel door.
  • It is important to use tire pressure recommended by Porsche manufacturer, not tire pressure listed on tire sidewall.
  • 2014 Porsche 911 Targa 4S tires can naturally lose on average 1 to 2 psi of tire pressure monthly, so check tire pressure regularly and add air as needed to maintain proper tire pressure at recommended inflation levels.
  • Check tire pressure in your 2014 Porsche 911 Targa 4S tires when they are "cold" and have not been driven for at least three hours. Never adjust tire pressure when tires are "hot".
  • Tire pressure in 2014 Porsche 911 Targa 4S tires can change by about 2.5% for each 10°F change in atmospheric temperature. Adjust tire pressure accordingly.
  • Underinflated tires can significantly reduce the life of 2014 Porsche 911 Targa 4S tires and reduce fuel efficiency by up to 5%.
  • Overinflating 2014 Porsche 911 Targa 4S tires does not increase their load-carrying capacity. Always use tire inflation value recommended for your 2014 Porsche 911 Targa 4S by manufacturer.
  • When replacing original equipment tires for 2014 Porsche 911 Targa 4S with plus size tires, or tires with different size, check tire load inflation chart to find proper tire pressure for your new tires.

It is important to maintain proper tire pressure for 2014 Porsche 911 Targa 4S tires. Low tire pressure will result in tire underinflation, and high tire pressure will result in tire overinflation, which can compromise tire safety, cause tire blowout, decrease fuel efficiency, cause uneven tire wear and reduce tire tread life. Check 2014 Porsche 911 Targa 4S tire pressure regularly, and monitor 2014 Porsche 911 Targa 4S tire inflation levels to avoid overinflated or underinflated tires.

Keep in mind that tire inflation value listed on tire sidewall is a maximum tire pressure the tire can be inflated to, and not a recommended tire pressure for 2014 Porsche 911 Targa 4S. Use recommended tire pressure listed on the tire pressure chart found on a sticker on driver's door jam or in 2014 Porsche 911 Targa 4S manual. Also, pay attention as your 2014 Porsche 911 Targa 4S may have different recommended tire pressure values for front and rear tires. Keep 2014 Porsche 911 Targa 4S tires inflated within reasonable psi range of the recommended levels.

If you replace 2014 Porsche 911 Targa 4S original equipment tires with optional tire sizes or you 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 tires on your 2014 Porsche 911 Targa 4S. Tires with the same load index, regardless of tire size, may carry the same load, but not always, and they 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.

Always refer to the 2014 Porsche 911 Targa 4S owner’s manual for any specific safety advice regarding the application of replacement tires.

2014 Porsche 911 Targa 4S replacement tires must have equal or greater speed rating compared to the original equipment tires if your 2014 Porsche 911 Targa 4S speed capability is to be maintained. It is recommended that tire installers refer to the 2014 Porsche 911 Targa 4S owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If 2014 Porsche 911 Targa 4S replacement tires have a lower speed rating than 2014 Porsche 911 Targa 4S original equipment tires, the vehicle’s speed must be restricted to that of the replacement tires.

Original equipment tires that come on your 2014 Porsche 911 Targa 4S will have the proper tire load index, so stick to that number or higher when you replace them with new 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 tire damage, premature tire wear or even tire blowout. You can check 2014 Porsche 911 Targa 4S manual to find the recommended tire size and load rating.

2014 Porsche 911 Targa 4S tire pressure changes with temperature, so check your 2014 Porsche 911 Targa 4S tire pressure when outside temperatures change. During colder months when temperatures drop, 2014 Porsche 911 Targa 4S tire pressure will decrease also by approximately 1 psi for each 10 degrees Fahrenheit. Maintain proper 2014 Porsche 911 Targa 4S winter tire pressure by adding air to your tires as needed to the recommended tire inflation levels.

2014 Porsche 911 Targa 4S tire pressure should be checked when tires are cold, after the 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.

If your 2014 Porsche 911 Targa 4S is equipped with tire pressure monitoring system (TPMS), pay attention to low tire pressure warning light being on. Ensure your 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 my recommended tire pressure for my 2014 Porsche 911 Targa 4S?
Recommended tire pressure for 2014 Porsche 911 Targa 4S is determined by the 2014 Porsche 911 Targa 4S manufacturer based on your vehicle's characteristics and tire sizes. Select your 2014 Porsche 911 Targa 4S tire size to find recommended tire pressure for 2014 Porsche 911 Targa 4S tires.
