Key Takeaways
- The correct Audi A3 tyre pressure ranges from 33–42 PSI depending on your model year, tyre size, and load conditions.
- Front and rear tyres on the Audi A3 require different pressures, and running them at the same PSI is one of the most common mistakes owners make.
- The Audi S3 and high-performance variants require significantly higher pressures than the standard A3, and using standard figures on an S3 can compromise handling.
- At Ordiniq, we designed an AutoPump that takes the guesswork out of maintaining your Audi A3's tyre pressure. Its digital gauge displays real-time readings in PSI, BAR, and kPa with precise PSI accuracy, and every purchase includes free UK delivery.
Audi A3 Tyre Pressure: The Exact Figures You Need
The recommended tyre pressure for most Audi A3 models is 33–42 PSI (2.3–2.9 bar / 228–290 kPa) for the front tyres and 30–39 PSI (2.1–2.7 bar / 207–269 kPa) for the rear tyres. Those ranges exist because the figures vary by model year, tyre size, and whether the vehicle is carrying a full load or travelling light.
The Audi A3 is a front-engined, predominantly front-wheel-drive car (except the Quattro variants). That means more weight sits over the front axle. To support that extra load and maintain a stable contact patch, the front tyres need slightly higher pressure than the rear.
Below, you’ll find more about the Audi A3 tyre pressure ranges by model variant and how to check and maintain the perfect tyre pressure all year round.

Audi A3 Tyre Pressure by Model Variant
The front and rear tyres on the Audi A3 require different pressures (Image source: Audi).
Standard A3 Models (2015–2020)
Third-generation A3 models built between 2015 and 2020 most commonly came fitted with either 225/45 R17 or 225/40 R18 tyres as standard. On the R17 setup, you're looking at 33 PSI front and 30 PSI rear. Step up to the R18 fitment, and those figures increase to 36 PSI front and 33 PSI rear. Always confirm which tyre size is actually fitted to your car before applying any pressure figure.
Standard A3 Models (2021–Present)
The fourth-generation A3, launched in 2021 on the MQB Evo platform, brought revised suspension tuning and a slightly different weight distribution compared to its predecessor. As a result, the recommended pressures increased.
On the standard 225/45 R17 fitment, Audi specifies 38 PSI (2.6 bar) front and 35 PSI (2.4 bar) rear for normal driving conditions.
S3 & High-Performance Variants
The Audi S3 sits in a different category entirely when it comes to tyre pressure. Fitted with 235/35 R19 tyres as standard, the S3 requires 42 PSI (2.9 bar / 290 kPa) at the front and 39 PSI (2.7 bar / 269 kPa) at the rear. These higher pressures are necessary to support the S3's increased kerb weight, its more aggressive suspension tuning, and the additional lateral forces generated during performance driving.

Where to Find Your Specific Tyre Pressure
You can find the recommended tyre pressure for your Audi A3 on the door placard (Image source: Audi).
General guidelines are a useful starting point, but your Audi A3 has a unique pressure specification based on its exact configuration. Audi provides the recommended tyre pressure information in at least two places on every A3, including one physical location on the car itself, and one in the documentation supplied with the vehicle.
Both should match. If they don't, the physical placard on the car takes priority as it reflects the specific build specification of that individual vehicle.
The Door Placard: Your Most Reliable Reference
Open the driver's door on your Audi A3 and look at the door sill or the edge of the door frame itself. You'll find a sticker that lists the exact recommended tyre pressure for your car. This placard is specific to your vehicle's build, meaning it accounts for your exact tyre size, wheel diameter, and axle load ratings. It typically shows both normal and laden pressure figures, often in bar and PSI side by side.
Owner's Manual & Digital Resources
Your Audi A3 owner's manual contains a dedicated section on tyre pressures, usually found in the maintenance or wheels and tyres chapter. It provides the full pressure table across all tyre sizes available for your model year, which is particularly useful if you're running a non-standard tyre fitment or planning to change wheel sizes.
Audi also provides tyre pressure data through its official owner resources online. If you've registered your vehicle with Audi, the MyAudi portal can surface vehicle-specific data, including tyre specifications.
Why the Ordiniq AutoPump Excels for Audi A3 Owners
The Ordiniq AutoPump is equipped with a smart auto shut-off feature, which prevents overinflating.
Maintaining precise tyre pressures on an Audi A3 requires a tool that meets the car's engineering standards, and that's where the Ordiniq AutoPump delivers. It offers digital PSI, bar, and kPa readouts in one device, so if you're working from the door placard in bar or a reference guide in PSI, you can dial in the exact number without any unit-conversion guesswork.
What makes it particularly well-suited to the A3 is the auto-stop inflation feature. All you have to do is set your target pressure, and it stops automatically, eliminating the risk of overinflation that comes with manual pumps. Given that the 2021–present A3 specifies 38 PSI front and 35 PSI rear, hitting those specific targets consistently every time is far easier with a pump that stops itself at the right number.

Frequently Asked Questions (FAQs)
What PSI should Audi A3 tyres be?
Most Audi A3 tyres should be between 33 and 42 PSI, depending on your model year, tyre size, and load. For the most common configuration, which is a 2015–2020 A3 on 225/45 R17 tyres, that's 33 PSI front and 30 PSI rear. The 2021–present A3 on the same tyre size steps up to 38 PSI front and 35 PSI rear.
Do front and rear tyres need different pressures on an Audi A3?
Yes. The front tyres on an Audi A3 require higher pressure than the rear because the front axle carries more weight. The difference is typically 3 PSI between front and rear on standard models. Running all four tyres at the same pressure will either underinflate the fronts or overinflate the rears, both of which negatively impact tyre wear, fuel economy, and handling balance.
Why does my Audi A3 tyre pressure warning light keep coming on?
If your Audi A3 tyre pressure warning light keeps triggering, the most common cause is a genuine slow puncture, even a nail that's sealed around the shaft can cause a gradual pressure drop of 1–2 PSI per day. Inflate the affected tyre to the correct pressure, monitor it over 24–48 hours, and if it drops again, have the tyre inspected.
Does tyre pressure change in cold weather?
Yes, tyre pressure drops in cold weather. As the air temperature falls, the air molecules inside the tyre contract, reducing pressure. The general rule is approximately 1 PSI of pressure loss for every 10°F (5.5°C) drop in temperature. For UK drivers, this means the shift from summer to winter can reduce tyre pressure by 4–6 PSI, even without a leak.
How does the Ordiniq AutoPump benefit Audi A3 drivers?
The Ordiniq AutoPump is a portable, digital tyre inflator designed for precise pressure management, which is exactly what the Audi A3's multi-variant pressure specifications demand. With clearly switchable units across PSI, bar, and kPa, you can match whatever unit your door placard displays without mental arithmetic or conversion errors. And with the auto shut-off feature, there's no risk of overinflating your tyres.
