1985 Audi sat at an interesting point in the brand’s U.S. story, with front-drive sedans, the increasingly refined 5000, and Quattro-badged performance cars all sharing the same showroom year. It was a make defined by European road manners, wind-cheating design, and a growing reputation for all-weather capability. Tire choice across 1985 Audi models varies by model rather than carrying one universal size, with six radial sizes spread across five model lines and rim diameters from 13 to 15 inches. The first thing to confirm is your exact model, then whether your car uses a 13-, 14-, or 15-inch fitment before narrowing down the right size and sidewall style.
Which Tire Size Is Right for Your 1985 Audi
Six tire sizes appear across 1985 Audi vehicles, and they vary by model rather than being shared across the full range. Because these sizes span 13-, 14-, and 15-inch rims, the real first step is confirming the correct model and wheel diameter before choosing a tire. Understanding that distinction up front saves time and helps match the right size to the right Audi.

Year(s): 1985|Fit(s): Coupe|Construction: Radial|Rim: 14 in
185/60R14 is a metric radial with a 185-millimeter section width, a 60-series aspect ratio, and a 14-inch rim diameter. It is available from Michelin as a Blackwall tubeless tire with a V speed rating, carrying a 149 mph ceiling. This size is specific to the Coupe and fits the car’s sportier late-classic Audi character without stepping outside the proper wheel diameter.
Five 1985 Audi models are covered here, from compact sedans to the flagship 5000 and the halo Quattro. Tire size varies by model, and in some cases even within a single model line, so identifying the exact model is more important than knowing only the year and make. Select your model below to narrow the fitment history and product choices to the right Audi.
1985 Audi 4000
The 1985 Audi 4000 was the compact, upright sport sedan of the range, known for crisp proportions and a distinctly European feel in everyday driving. Its tires mount on 13-inch rims, making it the smallest-wheel fitment in the 1985 Audi lineup.
Associated Tire Sizes:
175/70R13 — radial, period European touring fitment
The 1985 Audi 4000 Quattro brought all-wheel-drive traction to a compact sedan platform and helped establish Quattro as more than a rally calling card. Its fitments use 14-inch rims, with two distinct radial sizes that reflect the model’s more performance-oriented positioning.
The 1985 Audi 5000 was Audi’s aerodynamic executive sedan, a car that pushed the brand further upscale in the American market. Depending on configuration, it uses either 14-inch or 15-inch tire fitments, so model identification and wheel confirmation matter before choosing a tire.
The 1985 Audi Coupe carried the brand’s angular GT-era styling into a compact two-door package with a more personal, sporty emphasis than the sedans. Its tires mount on 14-inch rims and use a single low-profile radial size that suits the car’s sharper character.
The 1985 Audi Quattro stood apart as the turbocharged all-wheel-drive icon that gave the brand much of its performance identity in the 1980s. Its fitment uses 15-inch rims and shares one tire size with the 5000, though the car’s enthusiast and preservation priorities are often quite different.

205/60R15 — radial, sporty fitment with multiple sidewall looks
Thirteen products are available across six tire sizes for 1985 Audi vehicles. 175/70R13 has one Avon radial in Blackwall, 175/70R14 has one Travelstar radial in Narrow Whitewall, 195/60R14 has one Michelin radial in Blackwall, 185/70R14 has four radials from BFGoodrich, Avon, Dunlop, and Michelin in Blackwall and Wide Whitewall, 205/60R15 has four radials from Michelin, American Classic, Coker Classic, and BFGoodrich in Blackwall, Wide Whitewall, and RWL, and 185/60R14 has one Michelin radial in Blackwall.
These FAQs focus on how 1985 Audi tire sizing changes from model to model, what the various metric radial sizes mean, how sidewall style choices differ by size, and what to check when maintaining a low-use collector Audi.
Size Basics & Fitment
What tire sizes fit 1985 Audi vehicles?
1985 Audi vehicles use six sizes across five model lines: 175/70R13 for the 4000, 175/70R14 and 195/60R14 for the 4000 Quattro, 185/70R14 and 205/60R15 for the 5000, 185/60R14 for the Coupe, and 205/60R15 for the Quattro. Rim diameters vary by size, with 13-inch, 14-inch, and 15-inch applications in the same model year. Rim width guidance also varies by size where it is published: 175/70R13 works with 4.5 to 6.0 inches, 185/70R14 with 4.5 to 6.5 inches, 205/60R15 with 5.5 to 7.5 inches, and 185/60R14 with 5.0 to 6.0 inches.
That spread means year and make alone are not enough for a confident tire choice on a 1985 Audi. Two cars from the same year can need different rim diameters, and even the 4000 Quattro and 5000 can have more than one size depending on the application. Start with the exact model, then confirm the wheel diameter already on the car before comparing sidewall style, brand, or speed rating.
What does 175/70R13 mean on a 1985 Audi tire?
On a 1985 Audi, 175/70R13 is a metric radial size. The 175 is the nominal section width in millimeters, 70 is the aspect ratio, meaning the sidewall height is 70 percent of the section width, R identifies radial construction, and 13 is the wheel diameter in inches. In this year-make range, that size belongs to the Audi 4000 and is offered as an H-rated Blackwall radial, with the H symbol carrying a 130 mph ceiling.
That code tells you both physical fit and the general character of the tire. A 175/70R13 will not interchange with a 14-inch or 15-inch Audi wheel, even if another 1985 Audi model looks similar at a glance. Once the size is confirmed, you can move on to details such as rim width compatibility and whether the tire’s speed rating and styling suit the way your 4000 will actually be used.
Do all 1985 Audi models use the same tire size?
No, 1985 Audi models do not share one universal tire size. The 4000 uses 175/70R13, the Coupe uses 185/60R14, the Quattro uses 205/60R15, and the 4000 Quattro and 5000 each span two sizes. Only one size, 205/60R15, is shared across more than one model, and that common fitment applies only to the 5000 and Quattro.
That matters because Audi’s mid-1980s range covered compact sedans, coupes, executive cars, and all-wheel-drive performance models in the same showroom year. Tire sizing followed those differences. If you are standing in front of a 1985 Audi with replacement wheels or a long-ago tire change, the safest approach is to verify the model badge and wheel diameter before treating another 1985 Audi fitment as interchangeable.
Buying the Right Tire
What sidewall styles are available for 1985 Audi tires?
1985 Audi tire choices include Blackwall, Narrow Whitewall, Wide Whitewall, and raised white letter styling depending on size. Blackwall options appear across nearly the whole range, the 175/70R14 fitment for the 4000 Quattro carries a Narrow Whitewall option, 185/70R14 and 205/60R15 both have Wide Whitewall choices, and 205/60R15 also appears with raised white letters. Those are all radial tires, but the visual effect changes substantially from one sidewall treatment to another.
For a factory-European look on most 1985 Audi models, Blackwall is usually the most natural visual match. Whitewall and raised-letter treatments create a more individualized appearance and may suit a car that has already moved away from strict original presentation. Sidewall style does not change the need to match the correct size and rim diameter first, but it does shape how authentic or customized the finished car feels.
What brands make tires for 1985 Audi vehicles?
1985 Audi applications are covered by Avon, Travelstar, Michelin, BFGoodrich, Dunlop, American Classic, and Coker Classic. Avon covers 175/70R13 and 185/70R14, Travelstar covers 175/70R14, Michelin covers 195/60R14, 185/70R14, 205/60R15, and 185/60R14, BFGoodrich covers 185/70R14 and 205/60R15, Dunlop covers 185/70R14, and American Classic and Coker Classic both cover 205/60R15. Brand choice is therefore highly size-dependent on a 1985 Audi.
That means the right question is not simply which brand fits a 1985 Audi, but which brands fit your exact Audi size. The broadest brand spread appears in 185/70R14 and 205/60R15, while other sizes are much more specialized. Once you identify the correct size, you can compare whether you want a more European-style Blackwall presentation, a whitewall treatment, or in the 205/60R15 category, a raised white letter look.
What is the difference between Michelin Primacy 3 and BFGoodrich Radial T/A for a 1985 Audi?
For a 1985 Audi using 205/60R15, Michelin Primacy 3 and BFGoodrich Radial T/A differ in both appearance and rating. The Michelin is a Blackwall tubeless radial with a 91W rating, giving it a 168 mph speed ceiling, and it fits 5.5- to 7.5-inch rims. The BFGoodrich uses raised white letters, carries a 90S rating with a 112 mph ceiling, fits the same 5.5- to 7.5-inch rim range, and carries a 1,301-pound maximum load at 35 psi.
That makes the choice less about simple fitment and more about presentation and intended use. An owner seeking a subdued late-1980s European look may lean toward the Michelin, while a buyer drawn to period aftermarket styling may prefer the BFGoodrich lettering. Both are the same nominal size, but the sidewall look and speed symbol communicate two very different personalities on a 1985 Audi.
Fitting & Setup
What rim width do 1985 Audi tires require?
Rim width guidance for 1985 Audi tires depends on the exact size. 175/70R13 fits 4.5- to 6.0-inch rims, 185/70R14 fits 4.5- to 6.5-inch rims depending on the tire, 205/60R15 fits 5.5- to 7.5-inch rims, and 185/60R14 fits 5.0 to 6.0 inches. Some 14-inch sizes do not carry a published rim-width range in every product line, so the size and brand should be checked together rather than treated as one blanket rule.
That is especially important on older Audis that may have seen wheel swaps over the years. Two tires can share the same rim diameter but still want different rim widths for proper sidewall shape and tread behavior. Before mounting anything, compare your wheel width to the range for the exact tire you plan to run so the finished setup is both physically correct and visually proportionate.
Do 1985 Audi tires require inner tubes?
Several 1985 Audi tire options are clearly tubeless, while some sizes vary by product. 195/60R14 on the 4000 Quattro is tubeless, 205/60R15 has at least one tubeless option, and 185/60R14 for the Coupe is tubeless. Other sizes do not always carry a tube marking in the sidewall description, so tube use should be confirmed against the actual tire marking and wheel type rather than assumed from size alone.
That matters because a tubeless radial still needs a wheel in proper condition, with bead seats and valve hardware suitable for tubeless service. If your 1985 Audi still wears original wheels, or if the wheels have been restored, make tube decisions after checking the individual tire marking and the wheel’s condition. Matching the tire’s construction to the wheel setup prevents avoidable installation and air-retention problems.
Maintenance, Storage & Longevity
How should I store a 1985 Audi when the tires are fitted?
A 1985 Audi should be stored in a cool, dry space away from direct sunlight, electric motors, furnaces, welders, and other ozone sources that harden and crack rubber over time. Keep the tires clean, maintain proper inflation, and move the car periodically so one section of the tread is not carrying the load for months at a time. Because every 1985 Audi fitment here is radial, long static storage is generally easier on the tread shape than with older bias-ply constructions, but neglect still accelerates flat-spotting and sidewall aging.
For seasonal or long-term storage, many owners either roll the car a short distance every few weeks or support it carefully to reduce sustained load on the tires. The goal is not just preserving tread, but preserving the casing and sidewall. A well-stored set of tires will usually stay quieter, rounder, and more confidence-inspiring when the Audi returns to regular road use.
How long do tires on a 1985 Audi typically last?
On a collector-driven 1985 Audi, tire age usually matters more than miles. A good rule is to begin evaluating condition closely once tires reach five to seven years old and to treat about ten years as the point where replacement deserves serious consideration regardless of tread depth. The DOT date code on the sidewall is the clearest way to determine age, and older low-mile tires can still become hard, cracked, or internally fatigued.
That approach is especially important for cars that spend much of their lives indoors, because low use can make old tires look healthier than they really are. If your 1985 Audi still has strong tread but the rubber is aging out, appearance alone should not make the decision. A younger tire with the correct size and proper speed symbol is usually the wiser match for regular driving.
How often should tires on a 1985 Audi be inspected?
Tires on a 1985 Audi should be inspected before every drive and again before any extended highway outing. Look for sidewall cracking, cuts, punctures, bulges, irregular tread wear, and any pressure loss since the last use. On cars that sit for long stretches, also pay attention to vibration from temporary flat-spotting and check valve stems for age-related deterioration.
Frequent inspection is one of the simplest ways to protect both the car and the driver, especially on a vintage Audi that may only come out in fair weather. A quick walkaround can reveal problems early enough to avoid damaging rare wheels, bodywork, or suspension parts. If the tire feels different on the road than it did on the last outing, treat that change as a reason to inspect immediately rather than waiting for the next service interval.
Restoration & Authenticity
What tires were originally fitted to the 1985 Audi 4000?
A 1985 Audi 4000 would have been a radial-tire car from new, and its fitment in this year range is 175/70R13. That size reflects the European metric radial conventions Audi used in the mid-1980s, with relatively modest section width and a 13-inch rim. Original-equipment branding could vary by market and supply, so the most reliable restoration path is to match the correct size, radial construction, and era-appropriate sidewall look first.
For most restorations, that means starting with the tire code on the car, the wheel diameter, and any surviving period reference material before chasing brand-specific details. If your 1985 Audi 4000 is headed for marque judging, check with Audi club historians or event organizers about market-specific expectations. On a late-classic European sedan, getting the size and sidewall presentation right often matters as much visually as the badge on the sidewall.
Does correct tire fitment matter for showing a 1985 Audi?
Correct tire fitment absolutely matters when showing a 1985 Audi, especially if the car is being judged for originality or period presentation. Judges and knowledgeable enthusiasts will notice the difference between the correct size and wheel diameter, the proper radial construction for the era, and whether the sidewall style looks consistent with an Audi sold in the mid-1980s. A tire that is physically mountable but visually out of character can stand out quickly on a well-restored car.
That does not mean every show car must wear the exact same styling choice, but it does mean the tire should support the story the car is trying to tell. A preservation-minded Quattro, Coupe, or 5000 usually benefits from a restrained sidewall look, while a more personalized build may accept broader latitude. Event standards vary, so marque clubs and judging guidelines are still the best final authority before a serious show season.
What is the difference between Michelin XAS and Dunlop Sport Classic for the 1985 Audi 5000?
For a 1985 Audi 5000 using 185/70R14, Michelin XAS and Dunlop Sport Classic are both Blackwall radials, but they differ in rating and published details. The Michelin XAS is a tubeless 185/70VR14 with an 88V speed rating, carrying a 149 mph ceiling, and it fits 4.5- to 6.0-inch rims. The Dunlop Sport Classic is an 185/70R14 88H with a 130 mph ceiling and a maximum load of 1,235 pounds.
That comparison matters most to owners who want an authentically European look but still need to choose between two different expressions of the same size. The Michelin leans toward a higher-speed late-classic European specification, while the Dunlop stays within the same visual genre with a different rating profile. Either way, the car remains in the correct 185/70R14 family, which is the key first step for a faithful 5000 restoration.
Safety & Road Use
Are 1985 Audi tires safe for highway driving?
1985 Audi tires can be suitable for highway driving when the size, condition, and speed rating match the vehicle and the way it is used. The fitments here are all radials, with speed ratings that include T at 118 mph, H at 130 mph, V at 149 mph, S at 112 mph, and W at 168 mph depending on the exact size and tire. Those ratings comfortably cover normal U.S. highway speeds when the tires are healthy and properly inflated.
On a 1985 Audi, tire speed capability is only one part of the picture. Brakes, suspension bushings, wheel condition, alignment, and the overall mechanical state of a forty-year-old car often matter more to real-world confidence than the tire’s ultimate speed ceiling. Highway use is reasonable when the whole car is sorted, but an old tire or an unchecked chassis can undo the advantage of an otherwise appropriate speed-rated radial.
What inflation pressure should I use for 1985 Audi tires?
Inflation pressure on a 1985 Audi should follow the car’s factory guidance first, then be checked against the specific tire’s own maximum load and pressure information where that is published. In these fitments, 185/70R14 appears with 1,201 pounds at 35 psi and 1,235 pounds on another version, while 205/60R15 appears with 1,301 pounds at 35 psi and 1,521 pounds at 32 psi on another version. Those figures are tire capacity limits, not universal operating pressures for every 1985 Audi.
That distinction is important because one size should never inherit a pressure figure from another, and one product within a size may differ from another. Start with the owner’s manual or placard for the car’s intended operating pressure, then make sure the tire itself is suited to that use. If the Audi has changed wheels, carries unusual loads, or serves mainly as a touring car, pressure should be checked with that real use in mind.
What should I check before taking a 1985 Audi on a longer drive?
Before a longer drive in a 1985 Audi, inspect each tire for cracking, cuts, bulges, punctures, and uneven wear, then verify cold inflation pressure and confirm the spare is usable. Pay attention to valve stems, especially on older wheels, and look for any sign that the car has been sitting on underinflated tires. If the Audi has been stored, take the first few miles as a test for vibration, pull, or unusual noise from flat-spotted or aging rubber.
Tires are only one part of the pre-trip routine on a car from this era, but they are one of the easiest places to catch trouble early. A thorough check should also include wheels, brakes, fluids, and suspension condition so the car is not asking fresh tires to mask older mechanical problems. With vintage Audis, a calm, systematic inspection does more for confidence than any single performance spec.
