The 2014 Audi RS7 arrived as a high-performance sport sedan with the kind of aggressive wheel-and-tire presence that defines modern grand touring performance. Its blend of luxury, speed, and all-weather road capability makes tire selection especially important, because the car’s stance and response depend heavily on the correct size and wheel diameter. The 2014 Audi RS7 uses radial tires in two fitments, 275/30R21 and 275/35R20, tied to different 21-inch and 20-inch wheel setups. That creates a real choice between wheel-based fitment, available performance-oriented tire lines, and sidewall presentation. Before selecting a tire, confirm which wheel package is on the car and whether it remains stock.
Which Tire Size Is Right for The 2014 Audi RS7
The 2014 Audi RS7 uses two primary tire sizes, and the first thing to confirm is wheel diameter. One fitment uses a 21-inch rim and the other uses a 20-inch rim, so selection starts with the actual wheels on the car rather than a broad year-make-model assumption. Once that is settled, the decision shifts to tire line, sidewall style, and whether the tire suits the car’s intended street use and appearance.
275/30R21 is a modern metric radial size in which 275 represents section width in millimeters, 30 is the aspect ratio, R identifies radial construction, and 21 is the wheel diameter in inches. On a 2014 Audi RS7, this size belongs to the 21-inch wheel setup and supports the low-profile, performance-focused look expected from a large sport sedan. Its shorter sidewall makes wheel confirmation especially important because this is not interchangeable with the 20-inch fitment. Choose this size only after verifying that the car is running the 21-inch wheel package.
275/35R20 is a modern metric radial size with a 275-millimeter section width, a 35-series profile, radial construction, and a 20-inch rim diameter. For the 2014 Audi RS7, this size applies to the 20-inch wheel setup and offers several distinct product paths, including Blackwall, raised white letter, and Redline sidewall treatments across BFGoodrich, Nitto, and Pro-Trac lines. Product series also vary, including g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III. This is the size to evaluate when the car has 20-inch wheels and the goal is balancing fitment with brand and appearance preference.
The 2014 Audi RS7 Base keeps fitment simple in one sense because only one sub-model is covered, but tire selection still depends on wheel diameter. This RS7 can use either the 20-inch or 21-inch tire setup, so confirming the wheels on the car matters more than trim identification.

Tire Size & Fitment
What tire size fits a 2014 Audi RS7?
The 2014 Audi RS7 uses two primary tire sizes: 275/30R21 and 275/35R20. Both are radial fitments, but they are not for the same wheel diameter, so they serve different wheel setups on the car rather than functioning as one universal size.
The practical next step is to confirm whether the car has 20-inch or 21-inch wheels before choosing a tire. Since both sizes share the same 275-millimeter nominal width but use different aspect ratios and rim diameters, matching the tire to the wheel is more important than relying on the model name alone.
What size rim does a 2014 Audi RS7 use?
A 2014 Audi RS7 uses either a 20-inch or 21-inch rim, depending on which tire fitment is on the car. The 275/35R20 size corresponds to a 20-inch wheel, while the 275/30R21 size corresponds to a 21-inch wheel.
That makes wheel confirmation the key fitment check before tire selection. Looking at the sidewall of the current tire or measuring the wheel diameter will settle the question quickly, and it is especially important if the car has changed hands or may have aftermarket wheels fitted at some point.
Why does the 2014 Audi RS7 have more than one tire size?
The 2014 Audi RS7 has more than one tire size because it can be equipped with different wheel diameters. One fitment uses 275/35R20 on a 20-inch wheel, and the other uses 275/30R21 on a 21-inch wheel.
That does not mean both sizes should be treated as interchangeable on the same wheel. The right choice depends on the actual wheel package on the car, and any buyer should verify wheel diameter first, then compare the available tire options within that exact size for intended driving use and appearance.
Choosing the Right Tire
What should I consider when choosing a 275/35R20 tire for a 2014 Audi RS7?
Start with correct size and wheel compatibility, then compare the character of the available 275/35R20 options. This size is offered in several radial tire lines, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
From there, decide what matters most for the car’s use and presentation. Sidewall treatments include Blackwall, raised white letter, and Redline, and at least some options also publish rim-width and load details that are worth comparing against the wheels on the car before making a final selection.
What sidewall styles are available for 2014 Audi RS7 tires?
Within the available 275/35R20 fitment for the 2014 Audi RS7, sidewall styles include Blackwall, RWL, and Redline. RWL is a raised white letter presentation, while Redline gives the tire a stronger visual accent than a plain black sidewall.
The best choice depends on whether the goal is a subtle modern look or a more distinctive appearance. Sidewall style does not change the need for correct size and wheel match, so appearance should be the final layer of the decision after confirming that the tire suits the car’s 20-inch setup.
What brands offer tires for the 2014 Audi RS7?
For the 275/35R20 fitment on a 2014 Audi RS7, available brands include BFGoodrich, Nitto, and Pro-Trac. Those options span several series rather than a single uniform product type, which gives the buyer room to compare construction details, sidewall style, and other tire characteristics.
Brand selection should follow fitment, not replace it. Once the 20-inch wheel setup is confirmed, compare the available series and sidewall treatments in that exact size, and look at details such as rim-width compatibility, published load information where available, and the overall look you want on the car.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Audi RS7?
A period-style approach for a 2014 Audi RS7 usually starts with keeping the correct wheel-based fitment in place, either 275/35R20 or 275/30R21, rather than changing the overall visual balance of the car. Since this is a modern performance Audi, the correct tire size and profile have a strong effect on how authentic the stance appears.
For a cleaner original-era look, a Blackwall tire is the most understated option among the available 275/35R20 choices. Buyers who want a more individualized presentation can consider Redline or raised white letter styling, but appearance-driven changes should still stay within the proper size for the wheel on the car.
How does tire construction affect the appearance of a restored 2014 Audi RS7?
On a 2014 Audi RS7, construction is straightforward because the primary fitments are radial tires. That means the visible appearance difference is driven less by bias-ply-versus-radial considerations and more by maintaining the correct low-profile size and selecting the sidewall treatment that suits the car’s intended presentation.
A mismatched profile or wheel diameter can change the look of the RS7 more noticeably than brand choice alone. Keeping the proper 20-inch or 21-inch fitment preserves the car’s visual proportions, while Blackwall, Redline, or raised white letter sidewalls let the owner decide whether the finish should look restrained or more expressive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Audi RS7?
Yes, modifications can affect tire fitment on a 2014 Audi RS7. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body or fender alterations can all influence whether a 275/35R20 or 275/30R21 tire has the clearance and wheel match needed for proper use.
Even when the tire size matches one of the known RS7 fitments, the car should still be checked as it sits today. Steering clearance, suspension travel, and inner and outer clearance around the tire matter, especially on a performance sedan where wheel changes are common and sidewall height is relatively short.
What should I inspect before driving a 2014 Audi RS7 on new tires?
Before driving a 2014 Audi RS7 on new tires, inspect basic fitment and condition points first. Confirm the tire size matches the wheel diameter, check that the tire seats properly on the rim, and look over the surrounding suspension, brake, and fender clearances for anything that could interfere under steering or compression.
A short visual check after installation is worthwhile even on a modern car. Proper air pressure, secure valve stems, even tread seating, and the absence of rubbing marks all help establish that the setup is ready for road use, particularly if the RS7 has replacement wheels or other changes from stock configuration.
What should I check before a longer drive in a 2014 Audi RS7?
Before a longer drive in a 2014 Audi RS7, make sure the tires are the correct 20-inch or 21-inch fitment for the wheels on the car and inspect them for cuts, bulges, punctures, irregular wear, and visible air loss. A pressure check is also important, especially on low-profile performance sizes.
Longer trips put more emphasis on condition consistency across all four tires. It also helps to check for vibration, rubbing, or uneven wear patterns beforehand, because those signs can point to alignment, wheel, or suspension issues that may not be obvious during short local driving.
