The Audi A4 is one of the most popular luxury sedans on American roads, and tire choices split sharply between two buyer types: the comfort commuter who wants a quiet, long-lasting touring tire, and the S line driver who wants responsive performance rubber. This guide covers both, with specific picks for every A4 trim and size.
A4 tire sizes — know yours before you shop
The B9/B9.5 Audi A4 (2017 to present) comes in three common tire sizes based on trim: 225/50R17 on base Premium models, 245/40R18 on Premium Plus and S line trims, and 255/35R19 on Prestige with the sport package. Your exact size is printed on the sidewall of your current tires and on the sticker inside the driver door jamb.
The profile number (50, 40, 35) is the sidewall height as a percentage of width. A 245/40R18 has a noticeably shorter sidewall than a 225/50R17 — which affects ride comfort, cornering feel, and which tire brands stock your size.
Best all-season tires for the Audi A4
Michelin Pilot Sport All Season 4 — the top pick for A4 owners who want both dry sport character and wet-weather confidence. Available in all three A4 sizes. Excellent wet braking and low road noise, with treadwear ratings around 500 for competitive longevity in a sport tire.
Continental PureContact LS — the quietest and most comfort-focused all-season in A4 sizes. Best for the 225/50R17 and 245/40R18 buyer who prioritizes highway refinement over peak grip. Lower rolling resistance and very smooth ride on rough pavement.
Bridgestone Turanza QuietTrack — another strong quiet touring option in all three A4 sizes. Road noise suppression is its standout strength. Very comfortable on rough interstate surfaces with solid all-weather ratings.
Pirelli P Zero All Season Plus — Pirelli sport-oriented all-season for the A4 S line. Strong wet grip, available in 245/40R18 and 255/35R19, and a good match for quattro all-wheel drive in mixed conditions.
Best summer performance tires for A4 S line and sport trims
Michelin Pilot Sport 4S — the benchmark summer tire for the A4 S line. Exceptional dry grip, very strong wet traction for a max-performance summer tire, and available in 245/40R18 and 255/35R19. The right choice for drivers who want the sharpest A4 handling and are willing to run a second set or all-seasons in cold months.
Continental SportContact 7 — Continental flagship summer tire for A4 sport trims. Competes directly with the Pilot Sport 4S in 245/40R18 and 255/35R19. Marginal real-world differences; choose whichever is in stock at a better price.
Goodyear Eagle F1 Asymmetric 6 — a strong middle ground between sport touring and max-performance. Better dry traction than a touring tire at a lower price than the PS4S, with longer projected tread life.
A4 quattro tire tips
Quattro full-time AWD requires all four tires to be the same brand, model, and size. Running tires with significantly different tread depths between axles stresses the center differential. When replacing two tires, match the brand and model of the two remaining. When the tread depth difference across all four approaches 2/32 inch, replace all four.
Most U.S.-market A4 models come with conventional tires and a compact spare. If a previous owner installed run-flat tires, verify your TPMS calibration before mixing tire types on the same vehicle.
Frequently asked
What tire size does the Audi A4 use?
A4 Premium (17-inch wheels): 225/50R17. A4 Premium Plus and S line (18-inch): 245/40R18. A4 Prestige with sport package (19-inch): 255/35R19. Always verify on the door sticker — option packages vary the fitment by year.
How much do Audi A4 tires cost?
225/50R17: $120 to $170 per tire installed. 245/40R18: $145 to $200 per tire. 255/35R19: $165 to $240 per tire. A full set of four in the most common 245/40R18 size runs $580 to $800 at a local West Georgia shop.
Do I need all four tires to match on a quattro A4?
Yes. All four tires on a quattro AWD vehicle should match in brand, model, and size. The full-time AWD drivetrain can be stressed by significant mismatch in tire diameter or tread depth across axles. Replace in pairs at minimum, and all four when tread depths are within 2/32 of each other.
