The 2023 Audi RS e-tron GT sits at the high-performance end of Audi’s electric lineup, blending grand touring comfort with the aggressive stance and speed expected from an RS model. Its low roofline, wide track, and modern chassis tuning make tire selection especially important to both appearance and road behavior. This model uses staggered radial tire sizing, with 245/45R20 front and 285/40R20 rear on 20-inch wheels, or 265/35R21 front and 305/30R21 rear on 21-inch wheels. Available choices in the front fitment include blackwall, redline, and raised white letter presentations across several radial series. The key step is confirming wheel diameter and front-versus-rear position before comparing style, load, and intended use.
Which Tire Size Is Right for The 2023 Audi RS e-tron GT
The 2023 Audi RS e-tron GT uses four primary tire sizes because fitment is staggered by front and rear position and also split between 20-inch and 21-inch wheel packages. The first step is confirming wheel diameter, then identifying whether the tire is for the front or rear axle. Once that is settled, the decision becomes choosing the right radial tire within the correct size and appearance style.
245/45R20 is a metric radial size in which 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2023 Audi RS e-tron GT, this size is used at the front with the 20-inch wheel setup. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and raised white letter sidewall treatments across several tire series. This size is the one to focus on when replacing front tires on a 20-inch-equipped car and matching the intended look matters as much as fitment.
265/35R21 is a metric radial size that uses a 265-millimeter nominal width, a 35-series profile, and a 21-inch rim diameter. On the 2023 Audi RS e-tron GT, this is the front tire size for the 21-inch wheel package, so it belongs to a different setup than the 20-inch front fitment. Its lower-profile format reflects the larger wheel package and should be matched to the correct front axle position rather than treated as a general front-tire substitute. Confirming that the car is on 21-inch wheels is the essential first step before selecting this size.
285/40R20 is a metric radial size where 285 indicates nominal section width in millimeters, 40 is the aspect ratio, and 20 identifies the rim diameter in inches. On the 2023 Audi RS e-tron GT, this size is used at the rear with the 20-inch wheel package, creating a staggered fitment relative to the narrower 20-inch front tire. Its role is rear-axle specific, so it should be chosen as part of the 20-inch front-and-rear combination rather than mixed casually with the 21-inch package. Rear tire replacement starts with confirming both axle position and wheel diameter.
305/30R21 is a metric radial size with a 305-millimeter nominal section width, a 30-series profile, and a 21-inch rim diameter. On the 2023 Audi RS e-tron GT, this is the rear tire size paired with the 21-inch front fitment, making it part of the larger staggered wheel package. The very wide section and low-profile format mean it is important to keep this size tied to the correct rear position and wheel diameter. Buyers considering rear replacement on a 21-inch-equipped car should verify the existing wheel setup before comparing tire choices.
Fitment on the 2023 Audi RS e-tron GT is straightforward once front and rear positions are separated, but tire choice still depends on the wheel package. The covered front and rear sub-model entries use different sizes, so confirming axle position and wheel diameter matters before selecting a tire.

2023 Audi RS e-tron GT Base Front
The 2023 Audi RS e-tron GT Base Front uses one of two front radial sizes depending on whether the car has 20-inch or 21-inch wheels. Front tire selection starts with confirming the wheel diameter, then choosing among the available radial options in the proper size and sidewall style.
The 2023 Audi RS e-tron GT Base Rear uses a wider rear radial tire, again split between 20-inch and 21-inch wheel packages. Rear replacement should stay matched to the correct wheel diameter and staggered setup so the tire suits the actual axle position and package on the car.
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)

Tire Size & Fitment
What tire size fits a 2023 Audi RS e-tron GT?
The 2023 Audi RS e-tron GT uses a staggered radial setup rather than one tire size at all four corners. Front fitment is 245/45R20 with 20-inch wheels or 265/35R21 with 21-inch wheels, while rear fitment is 285/40R20 with 20-inch wheels or 305/30R21 with 21-inch wheels.
The most important step is matching both axle position and wheel diameter before choosing a tire. A front size should not be treated as a rear size, and a 20-inch fitment should not be confused with a 21-inch package. Checking the current wheel setup on the car is especially important if wheels have been changed.
What size rim does a 2023 Audi RS e-tron GT use?
The 2023 Audi RS e-tron GT uses either 20-inch or 21-inch rims, depending on the wheel package and tire position. The 20-inch setup pairs 245/45R20 front with 285/40R20 rear, while the 21-inch setup pairs 265/35R21 front with 305/30R21 rear.
Rim diameter is the first fitment detail to confirm because it immediately narrows the correct tire size range. Once wheel diameter is verified, the next step is confirming whether the tire is for the front or rear axle. That keeps the staggered setup intact and avoids ordering a tire that belongs to the other wheel package.
Why does the 2023 Audi RS e-tron GT have more than one tire size?
This model has more than one tire size because it uses a staggered arrangement and comes with two wheel diameters. The front tires are narrower than the rear tires, and the sizing changes again between the 20-inch and 21-inch wheel packages.
That means tire selection is not just a matter of naming the vehicle. The correct size depends on where the tire is mounted and which wheels are actually on the car. Looking at the existing sidewall size and wheel diameter before replacement is the safest way to stay aligned with the car’s current configuration.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2023 Audi RS e-tron GT?
Start with the fact that 245/45R20 is the front tire size for the 20-inch wheel package on the 2023 Audi RS e-tron GT. From there, compare radial construction details such as rim-width compatibility, sidewall style, tire series, and any load information that appears with the product.
Appearance can matter as much as specification on a modern performance car with a strong visual presence. Blackwall options keep a contemporary look, while redline or raised white letter choices create a more customized presentation. It also helps to confirm whether the tire is replacing one front tire or part of a matched front pair.
What sidewall styles are available for 2023 Audi RS e-tron GT tires?
In the available 245/45R20 fitment for the 2023 Audi RS e-tron GT, sidewall styles include blackwall, redline, and RWL, which is raised white letter. Those choices give the same size a noticeably different appearance even when the tire remains within the correct front 20-inch fitment.
The right sidewall style depends on the look you want from the car rather than a change in basic fitment. Blackwall suits a more understated modern presentation, while redline and raised white letter styles lean more custom and visually assertive. Keep the sidewall decision secondary to confirming the correct size, axle position, and wheel diameter.
What brands offer tires for the 2023 Audi RS e-tron GT?
Available tires in the 245/45R20 front fitment for the 2023 Audi RS e-tron GT include options from BFGoodrich, Nitto, and Pro-Trac. Those choices appear across several radial series, so the brand comparison is tied closely to tire character, sidewall styling, and rim-width specification rather than size alone.
Brand should be considered alongside the rest of the package instead of in isolation. Two tires can share the same size but differ in presentation and supporting specifications. Comparing the series name, sidewall treatment, and wheel compatibility details will usually tell you more than choosing by brand name alone.
Restoration & Appearance
How does tire construction affect the appearance of a 2023 Audi RS e-tron GT?
The 2023 Audi RS e-tron GT uses radial tires, so construction itself is not a bias-ply-versus-radial appearance question here. Visual character comes more from the wheel package and the sidewall presentation within the correct radial size, especially in the available 245/45R20 front fitment.
A blackwall tire keeps the car looking current and technically clean, while redline or raised white letter sidewalls give it a more personalized performance look. Because this is a modern RS model, appearance changes tend to come from style choices within the correct size rather than from switching to an older tire construction format.
Does correct tire fitment matter for a 2023 Audi RS e-tron GT appearance build?
Correct tire fitment matters a great deal because the 2023 Audi RS e-tron GT relies on a low-profile, staggered setup to preserve its intended stance. Using the proper front and rear sizes for the actual 20-inch or 21-inch wheel package helps the car keep the proportions and visual balance associated with this model.
Even on an appearance-focused build, the first priority is still matching axle position and wheel diameter. After that, sidewall style becomes the main visual decision in the available 245/45R20 options. A tire that looks right but is chosen for the wrong wheel package can disrupt both presentation and basic fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi RS e-tron GT?
Yes, modifications can affect tire fitment on a 2023 Audi RS e-tron GT, especially because the car already uses a staggered setup with low-profile tires. Aftermarket wheels, suspension changes, altered offsets, or body modifications can all change how much room is available around the tire.
Any modified car should be checked for wheel diameter, wheel width, and clearance at full steering lock and suspension movement before a new tire is chosen. That is particularly important when moving between 20-inch and 21-inch packages or replacing only one axle. A tire that matches the sidewall size still needs to suit the actual wheel and chassis setup.
What should I inspect before driving a 2023 Audi RS e-tron GT on new tires?
Before driving on new tires, inspect tire pressure, confirm the correct front or rear size has been mounted, and make sure wheel diameter matches the tire size. It is also smart to look for any visible issues such as cuts, bulges, uneven seating at the bead, or rubbing marks after installation.
A short, careful road check can confirm that the tires clear properly during steering and normal suspension movement. Recheck pressure after the first drive and keep an eye on any signs of vibration or air loss. On a staggered vehicle like the RS e-tron GT, even a simple front-rear mix-up can create avoidable problems.
How often should tires on a 2023 Audi RS e-tron GT be inspected?
Tires on a 2023 Audi RS e-tron GT should be inspected regularly, not just when tread looks worn. A quick visual check for pressure loss, sidewall damage, punctures, and uneven wear is worthwhile before normal use, and a more careful inspection makes sense before longer drives or after any wheel impact.
Because this model uses wide rear tires and low-profile fitments, small issues can become more noticeable in everyday driving. Checking pressures consistently and watching for shoulder wear or damage from road hazards helps catch problems early. If the car has been parked for long periods, inspect the tires again before returning it to regular use.
