The 2022 Audi A8 Quattro sits at the top of Audi’s sedan lineup, blending full-size luxury, all-weather capability, and the restrained design that has long defined the A8. Buyers looking at this exact model are usually balancing ride quality, appearance, and preserving the car’s intended road manners. Tire fitment centers on three radial sizes—255/45R19, 265/40R20, and 265/35R21—so the first step is confirming which wheel package is on the car. Once that is settled, the decision shifts to maintaining the proper metric radial size and profile while checking wheel diameter, overall tire proportions, and any changes made to the vehicle.
Which Tire Size Is Right for The 2022 Audi A8 Quattro
The 2022 Audi A8 Quattro uses three primary tire sizes, and the right one depends first on the wheel diameter installed on the car. All three fitments are radial metric sizes, but they pair with different rim diameters, so confirming whether the car has 19-inch, 20-inch, or 21-inch wheels is the key step before comparing tire options.
The size 255/45R19 identifies a metric radial tire with a 255-millimeter section width, a 45-series aspect ratio, and fitment for a 19-inch rim. On a 2022 Audi A8 Quattro, this size represents one of the factory-style radial fitments used with a specific wheel package rather than a universal size for every setup. Its profile places it within the larger luxury-sedan fitment story, where maintaining the intended balance of diameter, width, and sidewall height matters. This size should be chosen only after confirming the car is actually equipped with 19-inch wheels and the matching original fitment package.
The 265/35R21 size is a metric radial with a 265-millimeter section width, a 35-series profile, and a 21-inch rim diameter. For the 2022 Audi A8 Quattro, it is one of the larger-wheel fitments and belongs to a different wheel and tire combination than the 19-inch or 20-inch setups. The lower aspect ratio changes the visual character of the tire package and makes exact wheel-diameter confirmation especially important before selection. This size is appropriate when the car carries the 21-inch wheel arrangement and the goal is to stay with that specific fitment format.
A 265/40R20 tire uses a 265-millimeter section width, a 40-series aspect ratio, and mounts on a 20-inch rim. On the 2022 Audi A8 Quattro, this is a separate primary radial fitment that sits between the 19-inch and 21-inch packages in wheel diameter while keeping the wider 265-millimeter section width. Because it shares width with the 21-inch size but not the same rim diameter or profile, it should not be treated as interchangeable by size code alone. This fitment makes sense only after the wheel package has been verified and the tire selection is matched to that exact setup.
The covered 2022 Audi A8 Quattro L sub-model can use more than one tire size, so selection depends on identifying the wheel package actually installed on the car. Checking the sub-model still matters, but wheel diameter is the real deciding factor here.

Frequently Asked Questions
Tire questions for the 2022 Audi A8 Quattro usually come down to wheel-package identification, proper metric radial sizing, and making sure replacement tires match the car’s actual rim diameter. The answers below focus on fitment, selection, and practical checks before regular road use.
Tire Size & Fitment
What tire size fits a 2022 Audi A8 Quattro?
The 2022 Audi A8 Quattro uses three primary tire sizes: 255/45R19, 265/40R20, and 265/35R21. All three are radial metric fitments, and each size corresponds to a specific wheel diameter rather than serving as a one-size-fits-all option for every car wearing the A8 Quattro name.
The practical step is to confirm which wheel package is on the vehicle before choosing a tire. A 19-inch, 20-inch, or 21-inch rim requires the matching tire size, and the car should also be checked for any wheel changes made by a previous owner so the replacement tire matches the actual setup.
What size rim does a 2022 Audi A8 Quattro use?
A 2022 Audi A8 Quattro can use 19-inch, 20-inch, or 21-inch rims depending on the tire size fitted to the car. The 255/45R19 tire matches a 19-inch rim, the 265/40R20 matches a 20-inch rim, and the 265/35R21 matches a 21-inch rim.
That makes rim-diameter confirmation the first fitment check before ordering tires. Looking only at the vehicle year and model is not enough when multiple wheel packages exist, so the wheel itself and the current tire sidewall should both be verified to avoid choosing the right width and profile on the wrong rim diameter.
Why does the 2022 Audi A8 Quattro have more than one tire size?
More than one tire size applies because the 2022 Audi A8 Quattro was equipped with different wheel diameters. The three supported sizes—255/45R19, 265/40R20, and 265/35R21—reflect different factory-style wheel and tire combinations, all within the same overall luxury-sedan fitment range.
That means the correct choice depends on the exact wheel package on the car, not simply the model name. It is also wise to confirm whether the car still has its original wheels, since aftermarket replacements or winter-wheel packages can change the rim diameter and alter what tire size belongs on the vehicle now.
Choosing the Right Tire
What should I consider when choosing a 2022 Audi A8 Quattro tire?
Start with the exact tire size already assigned to the wheel package on the car: 255/45R19, 265/40R20, or 265/35R21. The key selection points are correct rim diameter, matching section width and profile, and staying with the proper radial construction used on the 2022 Audi A8 Quattro.
After size is confirmed, compare the tire against the way the car is actually used. A luxury sedan like the A8 benefits from preserving the intended proportions of the original fitment, so any replacement should be checked against the existing wheel setup, vehicle clearance, and any changes in suspension height or wheel design.
How do I choose between the available 2022 Audi A8 Quattro tire sizes?
The three sizes are not alternatives to be chosen by preference alone. A 2022 Audi A8 Quattro wearing 19-inch wheels needs 255/45R19, a 20-inch setup uses 265/40R20, and a 21-inch setup uses 265/35R21, so the correct size is determined by the wheel package already on the car.
The better comparison is not size versus size, but whether the installed wheels are the intended ones for the car. Once the wheel diameter is verified, the goal is to replace the tire with the same size format and profile family so steering feel, appearance, and clearance remain aligned with the existing setup.
Why is wheel-package confirmation so important on a 2022 Audi A8 Quattro?
Wheel-package confirmation matters because the 2022 Audi A8 Quattro spans three different rim diameters and three different tire sizes. Even though the sizes stay fairly close in overall proportions, 255/45R19, 265/40R20, and 265/35R21 are each tied to a particular wheel diameter and should be treated that way.
A quick visual estimate is not enough on a modern luxury sedan, especially if the car has seen previous owner changes. Checking the sidewall size code and the wheel diameter helps prevent ordering a tire that looks generally similar but does not match the rim or the tire package the vehicle is currently using.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Audi A8 Quattro restoration or preservation project?
Yes. Even on a modern luxury sedan, preserving the correct tire size for the installed wheel package helps maintain the intended appearance and stance of the 2022 Audi A8 Quattro. Using 255/45R19, 265/40R20, or 265/35R21 where each belongs keeps the car visually consistent with its proper wheel-and-tire combination.
For a preservation-minded owner, the first goal is accuracy in size and wheel diameter rather than chasing a different look. If originality matters beyond basic fitment, the car should be compared against build documentation, window-sticker records, or marque-specific references so the replacement tire matches the wheel package the vehicle was delivered with.
How does tire profile affect the appearance of a 2022 Audi A8 Quattro?
Tire profile has a visible effect on how a 2022 Audi A8 Quattro presents itself. The 255/45R19 carries a taller sidewall than the 265/35R21, while the 265/40R20 sits between them, so each wheel-and-tire package gives the car a slightly different visual balance without changing its overall luxury-sedan character.
That matters when replacing only tires and trying to preserve the car’s existing look. Mixing sizes outside the wheel package can alter sidewall height and throw off the intended presentation, so buyers focused on appearance should match the current rim diameter and tire size rather than selecting by width number alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Audi A8 Quattro?
Yes. Modifications such as aftermarket wheels, altered offsets, suspension changes, or lowering can affect tire fitment on a 2022 Audi A8 Quattro even when the size looks close to stock. The car’s original fitment range includes 19-inch, 20-inch, and 21-inch radial packages, and each depends on the wheel setup remaining compatible.
A modified car should be checked for fender clearance, steering clearance, and the exact wheel dimensions before replacing tires. Even a correct factory-style size can become a problem if the wheel width or offset has changed, so the safest approach is to match the tire to the vehicle’s current hardware, not assumptions about stock equipment.
What should I inspect before driving a 2022 Audi A8 Quattro on new tires?
Before regular road use, confirm that the new tires match the correct size for the installed wheels and check basic condition items around the car. Tire pressure, visible sidewall damage, tread condition, valve stems, and proper mounting should all be reviewed on a 2022 Audi A8 Quattro before the first sustained drive.
It also helps to look for any signs of clearance trouble once the car is on the ground and the steering is turned through its range. A short initial drive followed by another pressure and visual check can catch issues early, especially if the vehicle has low annual mileage or has recently had wheel service performed.
What should I check before a longer drive in a 2022 Audi A8 Quattro?
Before a longer trip, make sure the 2022 Audi A8 Quattro is wearing the correct radial tire size for its wheel package and that all four tires are in sound condition. Check inflation, inspect for cracking, bulges, cuts, uneven wear, and confirm there is no unexplained air loss before the car is driven at highway speeds.
Longer drives are often when age-related issues on lightly used cars finally show themselves, even if tread depth still looks acceptable. It is wise to inspect the spare setup if the car has one, verify wheel fasteners are secure after recent service, and watch for vibration or pull that may point to a mounting or fitment problem.
