2016 Audi Tire Fitment Guide

2016 Audi vehicles use 22 different tire sizes across 20 model lines: 205/55R16, 225/45R17, 245/45R17, 225/40R18, 245/40R18, 245/45R18, 235/35R19, 255/35R19, 255/40R19, 255/45R19, 245/35R19, 245/40R19, 255/35R20, 265/35R20, 275/35R20, 265/40R20, 265/30R20, 255/30R20, 255/35R21, 265/35R21, 275/30R21, and 275/35R21. They mount on 16- through 21-inch wheels, with rim-width guidance varying by size. Examples include 205/55R16 on the A3 Sportback e-tron, 245/45R17 on A4 models, 245/40R18 on A4, A5, S4, S5, and TT Quattro, and 275/30R21 on the RS7.

The practical takeaway is that year and make alone are not enough for 2016 Audi fitment. You need the exact model and the wheel diameter currently on the car, because many models span two or three factory-style sizes. Once those two points are confirmed, the right tire choice becomes much more straightforward.

On a 2016 Audi, 225/40R18 is a metric radial size. 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, the R identifies radial construction, and the 18 is the wheel diameter in inches. That size appears on the A3, A3 Quattro, A3 Sportback e-tron, and S3.

Knowing how to read that code helps you avoid common ordering mistakes. A tire can share the same 18-inch rim diameter yet still be wrong if the width or aspect ratio differs, so 225/40R18 should never be treated as interchangeable with another 18-inch Audi size without checking the full code on the sidewall.

No, 2016 Audi models do not use the same tire size. The compact A3 family can run 16-, 17-, 18-, or 19-inch sizes depending on model and package, the A4 and A5 family centers on 17-, 18-, and 19-inch fitments, the A6 and A7 range moves into 18-, 19-, and 20-inch sizes, and the A8, S8, RS7, and TTS stretch as far as 21-inch or ultra-low-profile 20-inch fitments.

That variation matters because many 2016 Audi models came with optional wheel packages that changed both rim diameter and tire proportions. If you are unsure which version you have, compare the sidewall code on the tires now, the wheel diameter, and the exact model badge before moving on to brand or speed-rating choices.

Most 2016 Audi tire sizes are offered in Blackwall form, which is the dominant look across the lineup and the most natural visual match for late-model European luxury and performance cars. A few sizes introduce more style variation: 265/35R20 appears in Blackwall, Redline, and RWL, while 275/35R20 is available in Blackwall and RWL. Those alternate sidewall treatments are concentrated in larger 20-inch performance sizes rather than spread across the full Audi range.

For a factory-style appearance on a 2016 Audi, Blackwall is usually the cleanest choice. Redline or raised white letter styling can create a custom look, but it changes the visual character of the car noticeably. If appearance matters as much as fitment, decide on sidewall style before narrowing the final product.

2016 Audi sizes are covered by BFGoodrich, Nitto, Michelin, M&H Racemaster, and Pro-Trac. BFGoodrich appears across much of the size range, Nitto covers many of the low-profile performance sizes, Michelin appears in 205/55R16, M&H Racemaster appears in 245/40R18 and 245/45R17, and Pro-Trac brings alternate sidewall styling in selected 20-inch sizes such as 265/35R20 and 275/35R20.

Brand choice on a 2016 Audi often comes down to how closely you want to match the tire's character to the car's use. Some owners prioritize a mainstream blackwall performance radial, while others are focused on a more specialized look or application. Once the size is confirmed, compare speed symbol, sidewall style, and rim-width suitability before deciding.

For 2016 Audi applications in 245/40R18, BFGoodrich and Nitto both offer Blackwall radial choices, but their details are not identical. BFGoodrich versions carry W and Y speed markings depending on the series and support rim widths from 8.0 to 9.5 inches, while Nitto's NT555 G2 uses a W speed rating and a rim-width range of 8.0 to 9.5 inches with 8.5 inches as the measured point. Load figures reach 1,609 pounds at 50 psi in both families where that figure is stated.

That means the comparison is less about basic fitment and more about the exact tire series and speed symbol you want on the car. If your Audi is already on an 18-inch setup, the smarter next step is checking which sidewall marking, load rating, and intended character align with how the car is driven rather than assuming every 245/40R18 behaves the same.

Rim-width requirements for 2016 Audi tires depend on size. Examples include 205/55R16 at 5.5 to 7.5 inches, 225/45R17 at 7.0 to 8.5 inches on most applications, 225/40R18 at 7.5 to 9.0 inches, 245/40R18 at 8.0 to 9.5 inches on most products, 255/35R19 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 use a single recommended measurement point inside that range.

Rim width matters because the same tire can mount on more than one wheel width, but not every wheel within the Audi lineup will suit every size. Before ordering, confirm both the diameter and width of the wheels on the car. That is especially important on cars that may have been upgraded from a smaller factory package to a wider aftermarket wheel.

Most 2016 Audi fitments here are modern radial tires and are generally presented as tubeless applications, but tube status can vary by product. One clear example is 205/55R16, where a Michelin version carries a TL marking, so the exact sidewall stamp matters. Across the rest of the range, the safest approach is to treat tube use as a product-by-product detail rather than a year-wide Audi rule.

That matters because tube decisions are tied to both the tire and the wheel. If your 2016 Audi still uses original late-model alloy wheels in sound condition, tubeless fitment is usually the expected direction, but the product marking should always be checked before installation. Confirm the valve-stem condition at the same time.

No single original 2016 Audi wheel works with all 22 sizes because the lineup spans 16-, 17-, 18-, 19-, 20-, and 21-inch diameters. A 225/45R17 requires a 17-inch wheel, a 245/40R18 requires an 18-inch wheel, and a 275/35R21 requires a 21-inch wheel. Even when two sizes are close in width, the rim diameter must match exactly.

Original wheels can be reused when the tire size matches their diameter and falls within the proper rim-width range. That means the question is not whether a tire fits a 2016 Audi in general, but whether it fits the specific wheel on your car. Measure the wheel and read the current sidewall before making any substitution.

A stored 2016 Audi should be kept away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that accelerate sidewall aging. Clean, dry floors and stable temperatures help preserve the rubber, and the car should either be moved periodically or supported in a way that reduces long-term static loading if it will sit for extended periods. Low-profile radials resist flat-spotting better than older bias-ply designs, but they still benefit from proper inflation during storage.

For a collector or seasonal-use Audi, tire care during downtime is as important as mileage. Check pressure before storage, cover the car if it sits near windows, and inspect the sidewalls when bringing it back into service. A car that looks fine cosmetically can still have age-related tire issues after long periods of inactivity.

On a 2016 Audi used as a collector, enthusiast, or low-mileage car, tire age usually matters more than tread wear. A sensible rule is to begin evaluating tires closely at about five to seven years and to treat ten years as a serious replacement threshold regardless of miles. The DOT date code on the sidewall gives the tire's week and year of manufacture, which is the key age reference.

That guideline is especially important on cars like the S, RS, and TT models, where low-profile fitments can look visually healthy even when the rubber has hardened with age. If your Audi is driven infrequently, do not let deep tread create a false sense of security. Age, storage conditions, and sidewall condition tell the fuller story.

Tires on a 2016 Audi should be checked before every drive and again before any longer trip. Look for sidewall cracking, cuts, bulges, punctures, uneven wear, and pressure loss, and make sure the tread has not worn irregularly from alignment or suspension issues. If a tire is tube-related by product or if the wheel uses serviceable valve hardware, inspect those parts as well.

Frequent inspection matters because many 2016 Audi fitments use short sidewalls that can hide damage until it becomes serious. A quick visual check takes only minutes and can reveal a problem before it affects ride quality or stability. Include the spare in the routine if the car carries one.

Yes, 2016 Audi tires in these sizes are suitable for highway use when they are the correct size, in good condition, and inflated properly. The speed symbols that appear across the range include W, rated to 168 mph, and Y, rated to 186 mph, with some sizes carrying one rating and others offering both depending on product. Those ceilings exceed normal U.S. highway speeds by a wide margin.

In real-world use, the car's condition often matters more than the speed symbol alone. Alignment, suspension wear, brake condition, and age-related tire hardening can affect confidence long before a speed rating becomes the limiting factor. For any 2016 Audi that sees regular road miles, safety begins with condition and correct fitment, not just the letter on the sidewall.

Inflation pressure for a 2016 Audi should follow the vehicle placard or owner's manual first, because factory pressure targets are tied to the exact model, axle loading, and wheel package. Tire pressure figures shown on the tire itself or in load data describe maximum rated conditions for that tire, such as 50 psi or 51 psi on some sizes, and should not be treated as the car's everyday operating pressure by default.

The best practice is to confirm the correct Audi specification for your exact model and then make sure the chosen tire's load rating supports that application. Do not transfer a pressure habit from one Audi size to another, especially when moving between 16-inch e-tron fitments and very low-profile 20- or 21-inch S and RS applications.

Before a longer drive in a 2016 Audi, inspect each tire for cracking, punctures, impact damage, uneven wear, and bulges, then verify cold pressure and look over the valve stems. Check that all four tires match the intended size for the car and that the spare, if present, is usable and properly inflated. On low-profile 19-, 20-, and 21-inch fitments, pay extra attention to inner sidewall damage from potholes.

Tires are only one part of a sensible pre-trip check on a modern performance or luxury Audi. Wheel condition, alignment feel, brake response, and suspension noises all matter, especially on heavier or more powerful models. If the car has been parked for a long stretch, a short local test drive before the main trip is a smart extra step.
