The Audi A6 is Audi's mid-size executive sedan — a direct rival to the BMW 5 Series and Mercedes E-Class. It uses Quattro all-wheel drive as standard in the US market. The A6 is available in standard 45 TFSI (2.0T), 55 TFSI (3.0T), and the performance-focused S6 (2.9T biturbo V6). Tire requirements range from touring all-season for the standard A6 to UHP summer fitments for the S6.
Audi A6 Tire Sizes by Trim
The Audi A6 45 TFSI (standard) ships on 18-inch wheels with 245/45R18 all-season tires as base fitment. Optional 19-inch wheels use 245/40R19 on all four corners — a square setup allowing full rotation. The 55 TFSI adds optional 20-inch wheels.
The Audi A6 55 TFSI standard fitment is 245/40R19 on 19-inch wheels — the same as the optional package on the 45. Premium trim and optional packages can fit 255/35R20 on 20-inch wheels.
The Audi S6 ships on 255/40R19 or 265/35R20 depending on model year and package — both are square setups enabling full rotation. The S6 is not staggered from the factory, which is practical for long-term tire maintenance.
Best All-Season Tires for Standard A6
For the 245/45R18 base fitment: the Michelin Primacy Tour A/S is the premium touring choice — quiet, comfortable, long-wearing, and capable in light snow. The Continental PremiumContact 6 is the European-spec alternative that works well in the A6.
For the 245/40R19 common fitment: the Michelin Pilot Sport A/S 4 delivers UHP all-season performance appropriate for the A6's more spirited driving character versus a typical family sedan. The Continental ExtremeContact DWS06+ is the value-tier UHP all-season alternative.
The Pirelli Cinturato P7 All Season Plus II is worth considering for A6 owners who prioritize low rolling resistance and quiet ride over outright performance — the A6 is not a track car and many owners value ride quality over handling limits.
Best Performance Tires for the S6
The Audi S6 with its 450-hp biturbo V6 benefits from genuine performance-tier rubber. On the 255/40R19 fitment: the Michelin Pilot Sport 4S is the benchmark summer tire for S6 ownership — the grip improvement over all-season tires in dry and wet conditions is substantial.
The Continental SportContact 7 in 255/40R19 is a strong competitor to the PS4S — excellent wet and dry grip, preferred by some drivers for its steering feedback characteristics.
For S6 owners who want summer-performance character year-round in Georgia's climate (mild winters, hot summers): the Pirelli P Zero (with Audi OE marking if available) is another strong option. Georgia's climate allows summer tires most of the year — only November through February requires monitoring for cold-weather performance.
Frequently asked
What size tires does the Audi A6 use?
Depends on trim and year. A6 45 TFSI: 245/45R18 (18-inch base) or 245/40R19 (19-inch option). A6 55 TFSI: typically 245/40R19 standard, 255/35R20 optional. S6: 255/40R19 (19-inch) or 265/35R20 (20-inch). Verify with your door jamb sticker.
Can you rotate Audi A6 tires?
Yes — the A6 uses the same size all four corners across all trims (it is not a staggered setup). Full front-to-rear rotation is possible and should be done every 5,000 to 7,500 miles. Quattro AWD benefits from well-matched tires on all four corners — rotation maintains even tread depth across the axles.
What are the best tires for the Audi A6 Quattro?
For the standard A6: Michelin Pilot Sport A/S 4 or Continental ExtremeContact DWS06+ in the correct size. For the S6: Michelin Pilot Sport 4S or Continental SportContact 7. The A6 Quattro AWD system works best with matched tires on all four corners — avoid mixing brands or compounds.
What tires come on the Audi S6?
The S6 typically ships with Pirelli P Zero or Continental SportContact tires in 255/40R19 or 265/35R20 depending on model year and trim package. Audi uses OEM-marked (OE-spec) tires from these brands that are validated for the specific Audi suspension tuning.
