Audi A4 Tire Pressure (Recommended PSI)
TL;DR
B9 A4 pressures depend on model year as well as tire size: 2019-2025 cars run about 32/32 PSI on base 17-18 inch tires up to 36/39 PSI on optional 19-inch tires, while 2017-2018 cars run 35/35 PSI on 17-inch and 41/44 PSI on 19-inch tires; older B8 A4 (2008-2016) sources disagree, roughly 32-35 PSI front and 29-35 PSI rear depending on tire size - always confirm on your own door-jamb placard.
Why there is no single number for the Audi A4
The Audi A4 has been built across several generations (B5 through B9), and within each generation Audi assigns different cold tire pressures to different wheel and tire combinations - not one pressure for the whole car. A base 17-inch all-season tire and an optional 19-inch performance tire on the same model year commonly carry different placard numbers, and on the larger wheel packages the rear pressure is frequently set higher than the front to balance handling and load distribution. Model year matters as much as tire size: the same B9 body was re-placarded at the 2019 facelift. This is confirmed by multiple independent listings for the same model years showing different PSI per tire size.
What we could verify
For the B9 generation the numbers split at the 2019 facelift, and two independent placard listings agree on both halves. On 2019-2025 cars, base 225/50R17 and 245/40R18 (93Y-rated) tires call for 32 PSI front and rear, a higher-load-rated 245/40R18 (97H) tire calls for 35 PSI front and rear, and the 245/35R19 performance tire package calls for 36 PSI front and 39 PSI rear. On the earlier 2017-2018 cars the same sizes carry markedly higher figures: 35 PSI front and rear on 225/50R17, 33-36 PSI front and rear on 245/40R18 depending on the listing, and 41 PSI front with 44 PSI rear on 245/35R19 - roughly 5 PSI above the facelift car on the same 19-inch tire. For the earlier B8 generation (2008-2016), sources disagree more: some list roughly 33 PSI front / 30 PSI rear for 225/50R17, others list 32 PSI front / 29 PSI rear (normal load) rising to 33/35 PSI (full load), and still others show 35/35 PSI for the same tire size in a different model year. Because of this spread, treat any single B8 figure as approximate and confirm it on your own vehicle.

| B9 pre-facelift (2017-2018) | 245/40R18 - listings vary by load rating | 33-36 | 33-36 |

| B8 (2008-2016) | 225/50R17 - normal load (sources vary) | 32-33 | 29-30 |
| B8 (2008-2016) | 225/50R17 - full load or alternate model-year listing (sources vary) | 33-35 | 35 |
| B8 (2008-2016) | 245/45R17 - Premium Plus | 33 | 35 |

Where to find the correct figure for your car
- Open the driver's door and look at the placard on the door jamb or B-pillar - it lists the exact PSI for your factory tire size, plus a separate figure for full-load/towing.
- Cross-check the owner's manual, which repeats the same chart and explains normal-load vs full-load values.
- Do not copy a figure from a different model year of the same generation - the B9 was re-placarded in 2019 and the 19-inch numbers moved by about 5 PSI.
- If you have changed tire size or wheel diameter from factory, the placard figure may no longer apply exactly - use it only as a baseline and consult a tire shop.

Frequently asked questions
Is Audi A4 tire pressure the same on every trim?
No. Even within one model year, the Audi A4 can specify different front and rear PSI depending on the tire size fitted - for example 32 PSI front and rear on a base 17-inch tire versus 36/39 PSI on an optional 19-inch performance tire on a 2020 car. Model year matters too: that same 19-inch size is placarded 41/44 PSI on 2017-2018 cars. Always match the figure to your specific tire size and model year on the door placard.
Why do front and rear pressures differ on some Audi A4 tires?
On the larger B9 performance packages Audi specifies a higher rear pressure than front - 36 PSI front and 39 PSI rear on 245/35R19 for 2019-2025 cars, and 41 PSI front with 44 PSI rear on the same size for 2017-2018 cars - to balance handling and load distribution. Smaller base tire sizes are usually set to the same PSI front and rear, such as 32/32 PSI on 225/50R17.
Where do I find the correct tire pressure for my specific Audi A4?
Check the sticker on the driver's door jamb or B-pillar, which lists the exact factory-recommended cold PSI for your car's specific tire size, along with a higher figure for full-load conditions. The owner's manual repeats this same information.
Do older Audi A4 generations (B8 and earlier) use the same pressures as newer ones?
No, and reliable published sources for the B8 (2008-2016) generation do not fully agree with each other, showing figures ranging roughly from 29 to 35 PSI depending on tire size and which listing you consult. Even inside the current B9 generation the pressures changed at the 2019 facelift. For any A4 older than a 2019 B9, treat published PSI figures as approximate and verify on your own door placard.
