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 and 55 TFSI ship on 19-inch wheels with 245/45R19 all-season tires as base fitment, a square setup that allows full rotation. Optional 20-inch wheels use 255/40R20.
Both the 45 TFSI and 55 TFSI share the same fitment options across Premium, Premium Plus, and Prestige trims.
The Audi S6 ships on 255/35R21 across all trims. It's a square setup that allows full rotation, and 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 245/45R19 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 255/40R20 optional 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 444-hp biturbo V6 benefits from genuine performance-tier rubber. On the 255/35R21 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 255/35R21 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 and 55 TFSI: 245/45R19 (19-inch base) or 255/40R20 (20-inch option). S6: 255/35R21. 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), so 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, and 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 ships on 255/35R21 summer tires carrying Audi OE markings (look for the AO stamp), validated for the specific Audi suspension tuning. Check your sidewall for the exact model when replacing.
