2017 Audi Tire Fitment Guide

2017 Audi vehicles use 21 tire sizes: 225/45R17, 225/50R17, 225/40R18, 245/40R18, 245/45R18, 235/35R19, 245/35R19, 255/35R19, 255/40R19, 255/45R19, 295/35R19, 255/35R20, 265/35R20, 265/40R20, 245/30R20, 305/30R20, 255/30R20, 275/35R20, 275/35R21, 275/30R21, and 265/30R20. Rim diameters span 17 through 21 inches, and the size depends heavily on model. A3-family cars center on 17-, 18-, and 19-inch fitments, A4 and A6 families use several 17- through 20-inch sizes, while A8, RS, S, TT, and R8 applications often use larger or staggered combinations.

That means a 2017 Audi owner should identify the exact model before doing anything else. Some families share sizes within the lineup, but Audi did not use one year-wide fitment across every sedan, coupe, hatchback, and performance model. If your car has staggered front and rear sizing, confirm axle position as well as diameter. Once the correct size is established, then it makes sense to compare brand, sidewall style, speed rating, and rim-width compatibility within that single fitment.

A metric size such as 225/40R18 breaks down into three main dimensions. The 225 is the nominal section width in millimeters, the 40 is the aspect ratio, meaning the sidewall height is 40 percent of the section width, and the R means radial construction. The final 18 is the wheel diameter in inches. That same logic applies across the 2017 Audi range, whether the size is 225/45R17 on an A3, 255/40R19 on an A6 or S7, or 305/30R20 on an R8.

Understanding the code helps you avoid ordering by appearance alone. Two Audi tires can both fit 19-inch wheels while being very different in width and sidewall height, and those differences affect proper fit on the wheel and overall stance. When comparing options, match all three dimensions, not just the rim diameter. If your car uses a staggered setup, the front and rear codes may differ even though both are radial metric sizes.

No, 2017 Audi models do not all use the same tire size. The A3, A4, A6, A8, TT, and performance S and RS models each have their own fitment patterns, and some models use multiple wheel packages within the same year. The R8 and RS3 also introduce staggered sizing, where front and rear tires are different. Even closely related models such as A5 Quattro and S5, or A7 Quattro and RS7, step into different widths, profiles, or rim diameters.

That variation matters because year and make alone are not enough to choose correctly for a 2017 Audi. Start with the exact model name, then confirm the wheel diameter currently on the car, and then verify whether the car uses the same size at all four corners. Owners of used cars should be especially careful, since wheel swaps are common on late-model Audis and can blur the line between stock and modified fitments.

Most covered 2017 Audi sizes use blackwall sidewalls, which align with the understated factory appearance expected on modern Audi sedans, coupes, and performance cars. A few larger performance sizes add more visual options. 265/35R20 is available in blackwall, redline, and RWL forms, 305/30R20 is available in blackwall, redline, and RWL forms, and 275/35R20 appears in blackwall and RWL versions. Those choices mainly affect appearance rather than the underlying fitment size.

For an Audi restoration-minded owner or someone preserving an OEM-style look, blackwall is usually the cleanest visual match for the era. Redline or raised white letter styling can create a more custom appearance, which may suit a modified car but not one kept close to original presentation. Decide whether you want factory-style restraint or a more personalized look before narrowing down the brand and series within a size that already fits your wheels.

Covered 2017 Audi fitments come from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. Many of the shared sedan and coupe sizes such as 225/40R18, 225/45R17, 245/45R18, and 255/35R20 are available from BFGoodrich and Nitto. 245/40R18 also includes an M&H Racemaster option, while some larger specialty sizes such as 265/35R20, 305/30R20, and 275/35R20 bring in Pro-Trac alongside other brands.

The practical choice comes down to your exact size first, then the character of the product line within that size. Some fitments have a broad mix of mainstream performance radials, while others are much more specialized. Once you know your model and wheel diameter, compare the available brands inside that single fitment instead of assuming that every Audi size has the same brand spread. That approach keeps the decision focused and prevents cross-shopping tires that never fit your car.

On larger 2017 Audi fitments where both appear, the main visible difference is sidewall presentation and the spec spread within the same size. In 265/35R20, BFGoodrich g-Force Phenom T/A comes in blackwall form with a Y speed rating and a 9 to 10.5 inch rim-width range, while Pro-Trac Street Pro III appears in redline and RWL versions. In 275/35R20, BFGoodrich g-Force options stay blackwall and include W or Y speed ratings, while Pro-Trac adds an RWL version.

That means the decision is usually about appearance and product character within the same fitment, not about changing to a different size. If you want a modern OEM-style look, blackwall BFGoodrich choices fit that theme. If you want a more customized sidewall treatment, Pro-Trac opens that door in certain sizes. Confirm your wheel diameter and exact size first, then compare the sidewall style and speed rating that best match how the car will be presented and used.

Rim-width requirements vary by 2017 Audi tire size. Examples with published ranges include 225/45R17 at roughly 7.0 to 8.5 inches, 225/50R17 at 6.0 to 8.0 inches, 225/40R18 at 7.5 to 9.0 inches, 245/40R18 at 8.0 to 9.5 inches, 245/45R18 at 7.5 to 9.0 inches, 255/35R19 and 255/40R19 at 8.5 to 10.0 inches, 265/35R20 at 9.0 to 10.5 inches, and 275/35R20 at 9.0 to 11.0 inches. Some products within a size also note a preferred measuring rim in the middle of that range.

That is why wheel diameter alone is not enough when fitting a 2017 Audi tire. A tire can mount on the correct 18-, 19-, or 20-inch wheel yet still be outside its recommended rim-width range if the wheel is too narrow or too wide. Before choosing a tire, verify the wheel width actually on the car, especially if it has aftermarket wheels. Matching both diameter and width keeps the tire profile correct and avoids unnecessary fitment surprises.

The covered 2017 Audi sizes are modern radial fitments, and the products that show tire-type markings point toward tubeless construction rather than tube-type service. Some size strings include TL markers explicitly, such as 245/40ZR18 97Y XLTL and 255/40ZR19 100Y XLTL. Other products do not spell out TL in the same way, so wording can vary by product even within similar size families. None of these fitments are presented as traditional tube-type collector tires.

For a 2017 Audi owner, the real checkpoint is the wheel and the exact sidewall marking on the tire you choose. If the car still uses original late-model Audi wheels in sound condition, tubeless radial service is the normal expectation. If the wheels have been changed, refinished, or repaired, inspect valve stems, bead-seat condition, and the product marking before installation. That matters even more on low-profile Audi fitments where sealing and wheel condition are critical.

No, original 2017 Audi wheels cannot be treated as interchangeable across all tire sizes because rim diameters run from 17 inches to 21 inches. A 225/45R17 fits a 17-inch wheel, a 245/40R18 fits an 18-inch wheel, a 255/40R19 fits a 19-inch wheel, and a 275/35R21 fits a 21-inch wheel. Several models also use different front and rear sizes, especially performance applications such as the R8 and RS3.

That means the original wheels can only be reused with tire sizes that match their exact diameter and fall within an appropriate rim-width range for that wheel. If your 2017 Audi still has its factory wheels, identify their diameter before doing anything else. If the car has aftermarket wheels, confirm both diameter and width and then compare them to the approved range for the intended tire. This matters most on low-profile sizes, where small differences become obvious quickly.

A stored 2017 Audi should be kept in a cool, dry, dark space away from direct sunlight, electric motors, welders, furnaces, and other ozone sources that age rubber. Clean the tires, keep them properly inflated, and move the car periodically so the same tread patch does not carry the load for months at a time. Because these are low-profile radial fitments, prolonged underinflation during storage can stress the sidewalls and make the car feel harsh or uneven when returned to service.

Owners who store an Audi seasonally often use tire cradles or stands if the car will sit for a very long time, but regular rolling and pressure checks are still important. A breathable indoor cover helps the car overall, yet tire care deserves its own routine. Before the first drive after storage, inspect every tire for cracking, pressure loss, or impact damage. That is especially important on larger 19-, 20-, and 21-inch packages with shorter sidewalls.

For a 2017 Audi, age matters at least as much as mileage. Collector and enthusiast cars often wear out their tires by time rather than tread depth, so a careful inspection around the five- to seven-year mark is wise, and many owners begin serious replacement consideration as tires approach 10 years from the DOT date code. Low-use Audis can still develop hardening, sidewall cracking, or internal age-related deterioration even if the tread looks respectable.

That is why service life should not be judged by miles alone. A lightly driven S5, A6, or TT may need tires sooner than expected simply because the rubber has aged. When evaluating an older set, look at the date code, how the car has been stored, whether the tires hold pressure consistently, and whether there is any visible cracking or irregular wear. Age-based evaluation is the safer habit for modern enthusiast cars like 2017 Audi models.

Tires on a 2017 Audi should be checked before every drive and given a more thorough inspection before any extended trip. Look for visible cracking, cuts, punctures, bulges, uneven wear, and pressure loss. On low-profile Audi fitments, impact damage from potholes can also show up as sidewall bruising or bent-wheel symptoms, so a quick walkaround matters more than many owners realize.

A longer pre-trip inspection should also include tread depth, valve-stem condition, and a check that all four tires match the intended size layout, especially on staggered setups. If the steering suddenly feels different or the car develops vibration, inspect the tires immediately rather than assuming it is normal road feel. Frequent checks are cheap insurance on performance-oriented Audi fitments, where short sidewalls and wider tread widths leave less margin for neglect.

The covered 2017 Audi tires are modern radial products, and the speed ratings shown are generally W or Y depending on size and product. W-rated tires carry a 112 mph ceiling, while Y-rated tires are rated for 186 mph or higher. Some sizes such as 235/35R19, 245/45R18, 255/35R19, 255/35R20, 255/40R19, 265/35R20, and 275/35R20 include both W- and Y-rated choices, so the exact tire matters as much as the size itself.

In practical use, normal highway driving is usually well below those ceilings, and the overall condition of the car often matters more than the tire's rated maximum. Alignment, wheel condition, suspension health, and correct inflation all shape how safely a 2017 Audi travels at speed. Choose a speed rating appropriate to the car's intended use, but do not treat the rating as permission to ignore the rest of the vehicle's condition or the road environment.

Inflation pressure on a 2017 Audi should follow the car's factory recommendation first, with the tire's own rated pressure understood as the ceiling associated with its load figure rather than an automatic running pressure. Examples of maximum load and pressure pairs include 225/40R18 at 1,389 pounds at 50 psi, 225/45R17 at 1,477 pounds at 50 psi, 245/45R18 at 1,764 pounds at 50 psi, 255/40R19 at 1,764 pounds at 50 psi, and 275/35R20 at 1,874 pounds at 50 psi.

Those figures should not be transferred from one size to another, and they should not replace the pressure placard or owner's manual recommendation for your exact 2017 Audi model. Start with the vehicle's specified pressure, then verify that the chosen tire is being used within its own load and pressure limits. If the car has non-original wheels or a staggered setup, double-check front and rear pressures separately rather than assuming a single number applies everywhere.

Before a longer trip in a 2017 Audi, inspect each tire for cracking, cuts, punctures, bulges, and uneven wear, and verify pressures when the tires are cold. Confirm that all four tires match the intended size arrangement for the car, especially if it uses a staggered setup such as an R8 or RS3. Check the spare as well if the car carries one, and make sure the valve stems and wheel faces show no sign of leakage or impact damage.

That tire check should be part of a broader pre-drive inspection that suits the age and performance level of the car. Brakes, fluids, battery condition, and suspension all influence how confidently a 2017 Audi can cover distance. On larger 20- and 21-inch packages, pothole damage and prior wheel repairs deserve extra attention. A few careful minutes in the garage can prevent a roadside problem far more effectively than relying on tread appearance alone.
