The 2023 Audi A6 allroad blends modern Audi luxury with wagon practicality, giving buyers a long-roof chassis that sits apart from the usual crossover crowd. Its raised stance and refined road manners make tire choice especially important, because the vehicle depends on a confident mix of ride quality, handling, and visual balance. This application uses a 245/45R20 radial tire on a 20-inch rim across the covered lineup. Available choices include blackwall performance-oriented tires as well as redline and raised white letter options for a more custom appearance. The real decision is less about size and more about selecting the right style, series, and road-use character for your allroad.
Which Tire Size Is Right for The 2023 Audi A6 allroad
The 2023 Audi A6 allroad uses one primary tire size: 245/45R20, and it is a radial fitment on a 20-inch rim. That same size is shared across Premium Plus and Prestige models, so the main choice is not between different fitment sizes, but between the available tire series, sidewall treatments, and the type of driving feel or appearance you want from the vehicle.
245/45R20 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 45 is the aspect ratio, R designates radial construction, and 20 is the wheel diameter in inches. On the 2023 Audi A6 allroad, that means a contemporary low-profile tire suited to the vehicle’s 20-inch wheel package. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and raised white letter sidewall treatments depending on the series. This size is the right starting point when selecting tires for either trim, but wheel width and the actual wheel setup should still be confirmed before purchase.
Tire fitment is straightforward across the covered 2023 Audi A6 allroad sub-models, because both use the same 245/45R20 radial size. Checking the sub-model still helps confirm that the vehicle retains its original 20-inch wheel setup and has not been altered with a different wheel and tire package.

2023 Audi A6 allroad Premium Plus
The 2023 Audi A6 allroad Premium Plus uses the same 245/45R20 radial tire size as the other covered trim. That keeps the fitment decision focused on tire series, sidewall style, and wheel-width compatibility rather than on sorting through multiple primary sizes.
The 2023 Audi A6 allroad Prestige also uses 245/45R20 radial tires on a 20-inch rim. For this trim, tire selection comes down to the kind of appearance and road character you want, along with confirming that the current wheels match the intended tire specification.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2023 Audi A6 allroad?
The 2023 Audi A6 allroad uses a 245/45R20 radial tire. That size applies across the covered Premium Plus and Prestige sub-models, making fitment unusually straightforward for buyers who are still on the original 20-inch wheel package.
Even with a single primary size, it is still smart to confirm what is actually on the vehicle before selecting tires. Some allroads may have been changed to aftermarket wheels, different offsets, or alternate wheel widths, and those changes can affect how a 245/45R20 tire works in practice.
What size rim does a 2023 Audi A6 allroad use?
The primary tire fitment for the 2023 Audi A6 allroad is built around a 20-inch rim. That matches the 245/45R20 tire size, where the final number in the size code identifies the wheel diameter in inches.
Rim diameter is only part of the fitment picture, so wheel width should also be checked before choosing among available tires. Some 245/45R20 products in this application call for a 7.5- to 9-inch rim-width range, which matters if the vehicle has replacement wheels instead of the original setup.
Do all 2023 Audi A6 allroad sub-models use the same tire size?
Yes. The covered 2023 Audi A6 allroad Premium Plus and Prestige sub-models both use the same 245/45R20 radial tire size. There is no split in primary tire size between those trims in this application.
That consistency makes shopping easier, but it does not remove the need to inspect the vehicle itself. A previous owner may have changed wheels or tires, and the safest approach is to verify the current rim diameter, wheel width, and overall clearance before replacing what is already on the car.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2023 Audi A6 allroad?
Start with the correct primary size, which is 245/45R20, and confirm that the tire is intended for a 20-inch wheel. From there, compare construction details, rim-width compatibility where stated, sidewall style, weight, and any load information that appears in the tire’s specifications.
The right choice depends on how the allroad is used and how you want it to look. A blackwall performance-style tire gives a different presentation than a redline or raised white letter option, so appearance, wheel setup, and expected road use should all be considered together.
What sidewall styles are available for 2023 Audi A6 allroad tires?
The available 245/45R20 tires for the 2023 Audi A6 allroad include blackwall, redline, and RWL sidewall treatments. RWL stands for raised white letter, giving buyers a more pronounced visual treatment than a standard black sidewall.
Sidewall style does not change the basic fitment size, but it can change the vehicle’s overall presentation in a noticeable way. Blackwall suits a more understated modern look, while redline and raised white letter options lean more custom, so the best choice depends on the allroad’s intended appearance.
What brands offer tires for the 2023 Audi A6 allroad?
245/45R20 tires for the 2023 Audi A6 allroad are available from BFGoodrich, Nitto, and Pro-Trac. The selection also spans several series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand alone should not be the only deciding factor. It helps to compare the tire series, sidewall treatment, rim-width specification, and the kind of visual character each option brings, especially since this allroad fitment includes both subtle blackwall and more expressive sidewall choices.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Audi A6 allroad?
A period-style approach on a 2023 Audi A6 allroad still begins with the correct 245/45R20 size, because the vehicle is a current-era design built around a modern low-profile radial. The appearance choice then shifts toward whether you want a restrained blackwall look or something more individualized.
Blackwall tires usually preserve the most contemporary factory-inspired presentation, while redline or raised white letter choices create a more customized visual statement. Since this is a modern Audi, appearance decisions are more about styling preference than historical restoration accuracy, so keeping the correct size should remain the first priority.
How does tire construction affect the appearance of a restored 2023 Audi A6 allroad?
Construction is straightforward on the 2023 Audi A6 allroad because the primary fitment is already radial. That means appearance differences come less from bias-ply-versus-radial concerns and more from the tire’s profile, sidewall treatment, and the way the chosen series complements the vehicle’s wheel design.
For an allroad kept close to its original visual character, maintaining the proper 245/45R20 radial size matters more than chasing novelty. Sidewall styling has the greatest visual effect here, so buyers should decide whether the goal is a clean modern look or a more personalized presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi A6 allroad?
Yes. A 2023 Audi A6 allroad may use 245/45R20 as its primary tire size, but aftermarket wheels, different offsets, suspension changes, or ride-height adjustments can all affect whether that size behaves the same way as it would on a stock setup.
Any time the vehicle has been modified, confirm more than just the number on the sidewall. Wheel width, brake clearance, fender space, and steering clearance all deserve a careful look, especially on a modern wagon with tight packaging around larger 20-inch wheel-and-tire combinations.
What should I inspect before driving a 2023 Audi A6 allroad on new tires?
Before putting a 2023 Audi A6 allroad into regular use on new tires, inspect the wheels for damage, confirm the tires match the intended 245/45R20 size, and make sure inflation is set correctly for the vehicle’s application. It also helps to look for uneven wear patterns that could point to alignment or suspension issues.
A visual check should include sidewall condition, tread surface, valve stems, and any sign of rubbing once the wheels are turned from lock to lock. After installation, a short road test can help reveal vibration, pull, or clearance problems before the vehicle goes on a longer drive.
How often should tires on a 2023 Audi A6 allroad be inspected?
Tires on a 2023 Audi A6 allroad should be inspected regularly, not just when tread depth becomes an obvious concern. Monthly pressure checks are a sensible routine, and the tires should also be looked over before road trips or any time the vehicle has been parked for a long period.
Consistent inspection helps catch early signs of irregular wear, cuts, bulges, punctures, or air loss before they turn into larger problems. On a vehicle using low-profile 245/45R20 tires, wheel damage from impacts is also worth watching for, since the tire’s shorter sidewall leaves less cushion than taller-profile fitments.
