The recommended tire pressure for an Audi A3 is 38-41 pounds per square inch (PSI) in the front tires and 38-41 PSI in the rear tires, depending on the exact year and trim level of your A3.

It’s vital that you maintain the correct air pressure in your tires at all times. Driving with overinflated or underinflated tires can reduce your handling and control of the vehicle, decrease your traction, cause uneven tire wear, and could even lead to a tire blowout!

What is the right tire pressure for an Audi A3?

The exact right tire pressure for your Audi A3 tires will vary depending on theyear your A3 was manufactured and your

trim level

. In general, both the front tires and the rear tires should always be between 38 PSI and 41 PSI, but they usually will not be the same.

To know for sure what the correct air pressure is for your tires, you’ll want to check your owner’s manual. To help you narrow it down, here’s a look at what tire pressure each iteration of the A3 needs, based on the model year:

Model year	Front tire pressure	Rear tire pressure
2006 Audi A3	35 psi	32 psi
2007 Audi A3	35 psi	32 psi
2008 Audi A3	38 psi	38 psi
2009 Audi A3	38-41 psi	38-41 psi
2010 Audi A3	38-41 psi	38-41 psi
2011 Audi A3	38-41 psi	38-41 psi
2012 Audi A3	38-41 psi	38-41 psi
2013 Audi A3	38-41 psi	38-41 psi
2014 Audi A3	35-41 psi	35-41 psi
2015 Audi A3	35-41 psi	35-41 psi
2016 Audi A3	35-41 psi	35-41 psi
2017 Audi A3	38-45 psi	39-45 psi
2018 Audi A3	38-45 psi	39-45 psi
2019 Audi A3	38-45 psi	39-45 psi
2020 Audi A3	38-41 psi	41 psi

As you can see, many of these model years have a range of possible recommended tire pressures. Where exactly in that range your A3 lands, depends on its specific trim level. Different trim levels will have different tire sizes—which will require different levels of air pressure.

The best way to determine precisely which trim level you have and what tire pressure you’ll need is by checking your owner’s manual. Alternatively, you can also examine the tires themselves. The exact tire size and recommended PSI will be printed on the tire.

How to check Audi A3 tire pressure

Knowing the correct tire pressure won’t do you much good if you don’t know how to check what level your tire pressure is currently at. If you’ve never checked your tire pressure before, don’t worry—it’s very easy.

You’ll need a

tire pressure gauge

before you can get started. A pressure gauge is a small tool that looks similar to a pen. They typically cost a few bucks and can be found at most gas stations. (You can also find pressure gauges built in to a tire fill-up station.)

Once you have your pressure gauge, remove the valve stem cap from the valve stem on one of your tires. Next, press the pressure gauge over the valve stem. The gauge will give you an exact reading of the current PSI in that tire. Repeat the process with all four tires to find out the pressure in each one.

Once you know how much pressure your tires have—and the correct amount of air pressure for them—you’ll know how much air to add or release.

Adding air to your tires

is easy at any air-filling station. Many gas stations have a free-to-use air-filling pump, and most pumps can be set to stop filling once the optimal pressure is detected.

How often should you check tire pressure?

In general, you should check your tire pressure at least once a month. Also, check it before any long drives or when the temperature outside drops significantly.

How to tell if your Audi A3 needs new tires

It’s a good idea to change your tires about once every five years—but the more you drive, the more often you’ll need new tires.

You should make a habit of checking your tires often. Give them a quick glance-over whenever you get in the car and inspect them carefully at least once a month. If you ever see signs that your tires are looking worn down, cracked, bulging, or riding unusually low to the ground, then it’s time to replace your tires.

You should also replace your tires if the tread on them is significantly worn down. Specifically, you should replace tires where the tread is at or less than 1/16th of an inch. An easy way to test this is by inserting a penny into the tread, Lincoln's head first. Can you still see the top of his head? If so, then it’s time for new tires.

How to reset the Audi A3 tire pressure monitoring system (TPMS) light

Your Audi A3 has a handy tool to help you know when your tire pressure is too low. The instrument cluster on your dashboard has a tire pressure monitoring system (TPMS) warning light. When your tire pressure drops too low, the light will come on—letting you know to add some air.

Unfortunately, TPMS lights are notorious for turning on when there’s not actually an issue. They may also stay on even after you’ve added air at a pump. In one of these scenarios, you’ll need to

reset your TPMS

to get the light to turn off.

Here’s how to reset the TPMS in an Audi:

Turn the car on, but do not start the engine.

On the Multi Media Interface (MMI) display touchscreen, locate and press the CAR button.

Select the SYSTEMS CONTROL button.

Select VEHICLE.

Select SERVICE & CHECKS.

Select TIRE PRESSURE MONITORING.

Select STORE TIRE PRESSURE.

Select YES, STORE NOW.

After that, the system will reset and the TPMS light should turn off!

Before you reset your TPMS, though, make sure that you check (and double-check!) that your tires do indeed have the right air pressure. The TPMS light can be annoying, but it is there for a reason. If the light is on when it shouldn’t be, then resetting it is fine. But if there’s actually a low-pressure situation, ignoring it could be disastrous.
