Audi S4 Recommended Tire Pressure

Check Audi S4 tire pressure charts with recommended tire inflation pressures for Audi S4 tires to improve fuel efficiency, extend tire life and drive safely. Select your Audi S4 year.

It is vital to maintain proper tire inflation pressures for Audi S4 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 Audi S4 tire pressure regularly, and monitor Audi S4 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 Audi S4. Use Audi S4 recommended tire pressure settings listed on the tire pressure chart found in Audi S4 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 Audi S4 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 Audi S4 may have different recommended tire inflation pressures for front and rear tires, especially if equipped with staggered tires. Keep your Audi S4 tires inflated at recommended tire inflation pressures at all times for your driving comfort and safety.

If you replace Audi S4 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 Audi S4 tires. Audi S4 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. Audi S4 replacement tires must have equal or greater speed rating compared to the original equipment tires if your Audi S4 speed capability is to be maintained. It is recommended that tire installers refer to the Audi S4 owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If your Audi S4 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 Audi S4 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 Audi S4 manual to find its original equipment tire sizes and load ratings. Always refer to the Audi S4 owner’s manual for any specific safety advice regarding the application of Audi S4 replacement tires.

Audi S4 tire pressure may fluctuate with ambient temperatures, so check Audi S4 tire pressure when ambient temperatures change. In winter when temperatures drop, Audi S4 tires may deflate by approximately 1 psi for each 10 degree Fahrenheit decrease in temperature. Maintain proper Audi S4 winter tire pressure by adding air to your tires as needed to the recommended tire inflation levels.

Audi S4 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 Audi S4 is equipped with tire pressure monitoring system (TPMS), pay attention to low tire pressure warning light being on. Ensure Audi S4 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.

Where do I find recommended tire inflation pressures for Audi S4?
You can find your Audi S4 recommended tire pressure in Audi S4 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 Audi S4 will be listed in psi, bar or kPa.

How to check Audi S4 tire pressure?
Proper Audi S4 tire inflation is essential to the overall tire performance and safety. To check tire pressure for Audi S4 you will need to know its recommended tire pressure and a tire pressure gauge. Check cold inflation pressures in Audi S4 tires with tire pressure gauge and adjust to Audi S4 recommended tire inflation pressures as needed by adding or releasing air. Make sure to check tire inflation for your Audi S4 regularly to ensure safe and comfortable drive.

Is my Audi S4 equipped with a tire pressure monitoring system (TPMS)?
If your Audi S4 is made after 2007, it should be equipped with tire pressure monitoring system. To confirm if your Audi S4 has TPMS, turn on the ignition without starting the engine. If a tire icon with an exclamation sign lights up on your dashboard, your Audi S4 is equipped with TPMS. You can also check Audi S4 owner's manual for more information.

Why is Audi S4 tire pressure warning light on?
If your Audi S4 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 Audi S4 low tire pressure warning light is on, check all Audi S4 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 Audi S4 tire pressure monitoring system?
To reset tire pressure monitoring system for Audi S4, make sure front and rear tires are inflated to the recommended levels. Refer to your owner's manual on how to reset Audi S4 TPMS.

What is recommended winter tire pressure for Audi S4?
