The Audi A8 is the Audi flagship luxury sedan — a direct competitor to the BMW 7 Series and Mercedes-Benz S-Class. It uses air suspension, a Quattro AWD system, and is available as a plug-in hybrid A8 L TFSI e. Tire choice should balance the expected flagship refinement with the AWD quattro dynamics and, for TFSI e owners, low rolling resistance.
Audi A8 tire sizes
The 2018 to present A8 uses 255/45R19 on the standard 19-inch wheels. The optional 20-inch Sport package uses 265/40R20. The 21-inch package uses 265/35R21 (some trims spec 275/35R21) — typically a square, non-staggered fitment.
Earlier A8 models (2011 to 2017) commonly used 255/45R19 on standard wheels or 265/40R20 on larger packages. The A8 L long-wheelbase shares the same wheel sizes as the standard A8. Verify on the door sticker.
Best tires for the Audi A8 — 19 and 20-inch
Continental PureContact LS (255/45R19, 265/40R20) is the top comfort pick for the A8: exceptionally quiet, a smooth ride, a 70,000-mile warranty, and strong wet performance. It's a natural fit for Audi flagship comfort expectations.
Michelin Pilot Sport All Season 4 (255/45R19, 265/40R20) is the best sport all-season for A8 owners who want Quattro dynamics to come through in the tires. Available in both sizes, and noticeably sharper than the Continental, though slightly firmer riding.
Pirelli Cinturato P7 All Season Plus II (255/45R19) — Pirelli touring all-season with good wet scores and ride quality. Available in 255/45R19. A quiet, refined choice for A8 owners prioritizing smoothness.

Best tires for the Audi A8 S line — 21-inch
Michelin Pilot Sport 4S (265/35R21) is the summer benchmark for A8 owners on the 21-inch package. It's summer-only rubber, though — best left off the car once winter hits.
Pirelli P Zero (265/35R21) — Pirelli is a common OEM supplier on German luxury flagships. P Zero in this size is available and competes directly with the PS4S in summer performance.

Frequently asked
What tire size does the Audi A8 use?
Standard (19-inch): 255/45R19. Sport 20-inch: 265/40R20. 21-inch package: 265/35R21 (square fitment on most trims). Verify on the driver door sticker.
How much do Audi A8 tires cost?
255/45R19: $170 to $265 per tire. 265/40R20: $200 to $305 per tire. 21-inch set all four installed: $900 to $1,400.
Should I match all four tires on my quattro A8?
Yes. Like every quattro Audi, the A8 works best with all four tires the same brand, model, and size, so the full-time all-wheel drive isn't fighting a diameter mismatch. Replace in pairs at a minimum, and go all four once the tread depths drift apart. A shop can measure and tell you which situation you're in.
Do I need a separate winter set for my A8?
Only if you're running the summer tires that come on the largest wheel package — those go hard and lose grip in the cold. On the smaller-wheel all-season fitments, West Georgia winters are usually no problem. If you split time up in the north Georgia mountains during winter, a dedicated cold-weather set is the safe play.
