1991 Audi sat at an interesting point in the brand’s American story, balancing front-drive luxury sedans, Quattro all-weather performance models, and a flagship V8 sedan that pushed Audi further upscale. The lineup ranged from the compact 80 and 90 to the larger 100 and 200 family, with coupe and Quattro variants adding more specialized fitments. Across 10 models, 5 tire sizes were used, and the main choice comes down to identifying the correct model first because sizing varies across the range rather than carrying over uniformly. Before choosing a tire for 1991 Audi, confirm the exact model and whether your car uses a 14-inch or 15-inch wheel.
Which Tire Size Is Right for Your 1991 Audi
Five tire sizes are used across 1991 Audi models, and they vary by model rather than being shared across the full lineup. Because these sizes span both 14-inch and 15-inch wheel fitments, the real decision starts with confirming the correct model and rim diameter before comparing sidewall style, speed rating, or brand character. Understanding that distinction first saves time and helps match the tire to the right Audi.
Year(s): 1991|Fit(s): 100, 100 Quattro|Construction: Radial|Rim: 15-in rim
195/65R15 is a radial metric size with a 195-millimeter section width, a 65-series aspect ratio, and fitment for a 15-inch wheel. It is a model-specific size for the 1991 Audi 100 and 100 Quattro. Buyers restoring or maintaining those cars should stay focused on this exact size first, then compare product details such as sidewall treatment and speed marking at the product level.
Year(s): 1991|Fit(s): 200, 200 Quattro, Coupe Quattro|Construction: Radial|Rim: 15 in
205/60R15 is a radial metric size with a 205-millimeter section width, a 60-series aspect ratio, and a 15-inch rim diameter. This size is available from Michelin, American Classic, Coker Classic, and BFGoodrich in Blackwall, Wide Whitewall, and RWL styles, and speed ratings vary by product, including S rated to 112 mph and W rated to 168 mph. It is specific to the 1991 Audi 200, some 200 Quattro applications, and the Coupe Quattro, so it is a good choice when you want the correct fitment while still deciding between a more original-looking sidewall and a more modern performance-oriented presentation.
Year(s): 1991|Fit(s): 200 Quattro, V8 Quattro|Construction: Radial|Rim: 15 in
215/60R15 is a radial metric size with a 215-millimeter section width, a 60-series aspect ratio, and fitment for a 15-inch wheel. American Classic, BFGoodrich, and Dunlop offer this size in Wide Whitewall, RWL, Redline, and Blackwall styles, and speed ratings vary by product, including S rated to 112 mph and V rated to 149 mph. This size is specific to the 1991 Audi V8 Quattro and some 200 Quattro applications, making it the right path for buyers who need the larger 15-inch fitment with either a traditional collector-car look or a more understated blackwall appearance.
Year(s): 1991|Fit(s): 80, 80 Quattro, 90|Construction: Radial|Rim: 14 in
175/70R14 is a radial metric size with a 175-millimeter section width, a 70-series aspect ratio, and a 14-inch rim diameter. Travelstar offers this size with a Narrow Whitewall sidewall and a T speed rating to 118 mph. It is specific to the 1991 Audi 80, 80 Quattro, and 90, so buyers with those compact Audi sedans should confirm the 14-inch wheel fitment before moving on to product selection.
Year(s): 1991|Fit(s): 90 Quattro|Construction: Radial|Rim: 15-in rim
205/50R15 is a radial metric size with a 205-millimeter section width, a 50-series aspect ratio, and fitment for a 15-inch wheel. This is a model-specific size for the 1991 Audi 90 Quattro. Buyers with that sportier Quattro sedan should treat this size as the starting point and verify the actual wheel before comparing tread style or sidewall presentation.
Ten 1991 Audi models are covered here, spanning compact sedans, midsize and full-size luxury cars, Quattro variants, and a grand-touring coupe. Tire size varies by model, so year and make alone are not enough; identifying the exact model is the first step before choosing a tire. Select a model below to explore its model-specific fitment history and products.
1991 Audi 100
The 1991 Audi 100 was Audi’s front-drive midsize luxury sedan, known for clean aerodynamic styling and a refined highway character. Its tires mount on 15-inch wheels, which places it in a different fitment group from the smaller 14-inch Audi 80 and 90 sedans.
The 1991 Audi 100 Quattro paired the 100’s upscale sedan format with Audi’s signature all-wheel-drive system, appealing to buyers who wanted year-round traction without stepping into the larger 200 or V8. Its tire fitment uses a 15-inch wheel, matching the basic wheel diameter of several larger Audi models from the same year.
The 1991 Audi 200 sat above the 100 in Audi’s range and carried a more premium, executive-sedan character. It uses a 15-inch wheel fitment, and that places it alongside other upper-range 1991 Audis rather than the smaller 14-inch 80 and 90 models.
The 1991 Audi 200 Quattro blended Audi’s larger luxury sedan body with Quattro traction and a more performance-oriented identity than the standard 200. It uses 15-inch wheel fitments, but unlike most models in the range, it appears with two applicable tire sizes, so confirming the actual wheel and current setup matters before ordering.
The 1991 Audi 80 was the compact sedan in Audi’s U.S. lineup, offering a lighter and more efficient package than the larger 100 and 200. Its tires mount on 14-inch wheels, which separates it from most of the year’s larger Audi models.
The 1991 Audi 80 Quattro gave the smaller Audi sedan the added traction and identity of the Quattro system while keeping the tidy proportions of the 80 platform. It uses a 14-inch wheel fitment, sharing its tire size with the standard 80 and the front-drive 90.
The 1991 Audi 90 occupied a slightly more upscale and better-equipped position than the 80, while still using the compact Audi sedan architecture. Its tire fitment mounts on 14-inch wheels, unlike the 15-inch setup used by the 90 Quattro.
The 1991 Audi 90 Quattro was the sport-oriented compact Audi sedan of the group, combining the 90 body with all-wheel drive and a more enthusiast-focused mission. It uses a 15-inch wheel fitment and stands apart from the standard 90 with its own distinct tire size.
The 1991 Audi Coupe Quattro brought Audi’s all-wheel-drive formula into a sleek two-door grand-touring body, making it one of the most distinctive models in the lineup. Its tires mount on 15-inch wheels, sharing wheel diameter with the larger 200 family but in a coupe application with its own character.
The 1991 Audi V8 Quattro was Audi’s flagship luxury sedan, combining V8 power, permanent all-wheel drive, and a more exclusive place in the brand’s range. It uses a 15-inch wheel fitment and shares its tire size with part of the 200 Quattro family rather than with the smaller Audi sedans.
Eleven products are available across 3 tire sizes for 1991 Audi vehicles. The 205/60R15 includes 4 radial choices from Michelin, American Classic, Coker Classic, and BFGoodrich in Blackwall, Wide Whitewall, and RWL styles; 215/60R15 includes 6 radial choices from American Classic, BFGoodrich, and Dunlop in Wide Whitewall, RWL, Redline, and Blackwall styles; 175/70R14 includes 1 radial Travelstar in Narrow Whitewall. Confirm your exact size first, since speed ratings can vary within a size.
These FAQs cover how tire sizing changes across the 1991 Audi range, which models share 14-inch or 15-inch fitments, what sidewall and brand choices exist in the available sizes, and what to check for occasional-use collector and enthusiast driving.
Size Basics & Fitment
What tire sizes fit 1991 Audi vehicles?
1991 Audi vehicles use five sizes across the model range: 195/65R15 for the Audi 100 and 100 Quattro, 205/60R15 for the Audi 200, Coupe Quattro, and some 200 Quattro applications, 215/60R15 for the V8 Quattro and some 200 Quattro applications, 175/70R14 for the Audi 80, 80 Quattro, and 90, and 205/50R15 for the 90 Quattro. Rim diameters are either 14 inches or 15 inches depending on model.
That means a 1991 Audi owner should identify the exact model before focusing on tread style or brand. Where rim-width guidance is available, 205/60R15 fits 5.5- to 7.5-inch rims, while 215/60R15 ranges from 5.5- to 7.5-inch or 6.0- to 7.5-inch rims depending on the tire. Matching the exact model and wheel diameter first keeps the rest of the selection process straightforward.
What does 175/70R14 mean on a 1991 Audi tire?
On a 1991 Audi, 175/70R14 is a metric radial size. The 175 is the nominal section width in millimeters, 70 is the aspect ratio, R means radial construction, and 14 is the wheel diameter in inches. For 1991 Audi applications, that size belongs to the Audi 80, 80 Quattro, and 90.
That decoding matters because it separates the compact 14-inch Audi fitment from the 15-inch sizes used on larger or more performance-oriented models. A buyer with one of those compact sedans should stay with the 14-inch fitment family first, then compare sidewall appearance and speed rating. It also helps prevent confusion with the visually similar but different 15-inch sizes used elsewhere in the 1991 Audi lineup.
Do all 1991 Audi models use the same tire size?
No, 1991 Audi models do not all use the same tire size. The lineup spans five sizes across ten models, with compact sedans using 175/70R14, midsize 100 models using 195/65R15, larger 200 and Coupe Quattro applications using 205/60R15, the V8 Quattro and some 200 Quattro applications using 215/60R15, and the 90 Quattro using 205/50R15.
That variation reflects how broad the 1991 Audi range was, from entry luxury sedans to Quattro performance and flagship V8 models. If you know only that you have a 1991 Audi, that is not enough to choose a tire correctly. The next step is confirming whether the car is an 80, 90, 100, 200, Coupe Quattro, or V8 Quattro, then matching the wheel diameter and tire size from there.
Buying the Right Tire
What sidewall styles are available for 1991 Audi tires?
Sidewall style depends on the size you need for your 1991 Audi. The 205/60R15 is available in Blackwall, Wide Whitewall, and RWL form, while the 215/60R15 adds Redline alongside Blackwall, Wide Whitewall, and RWL. The 175/70R14 appears as a Narrow Whitewall in the available product range.
For a 1991 Audi, blackwall is generally the most natural visual fit if you want an appearance close to what most buyers would expect from a late-1980s to early-1990s German luxury or sport sedan. Whitewall, redline, and raised-white-letter styles can still be useful if the goal is a custom presentation. Sidewall treatment changes the car’s look more than the dimensions do, so choose it with the car’s intended character in mind.
What brands make tires for 1991 Audi vehicles?
1991 Audi tire coverage comes from several brands depending on size. The 205/60R15 is available from Michelin, American Classic, Coker Classic, and BFGoodrich. The 215/60R15 is available from American Classic, BFGoodrich, and Dunlop, while the 175/70R14 is available from Travelstar.
That mix gives a 1991 Audi owner a choice between more modern touring-style blackwall tires and collector-oriented sidewall treatments such as whitewall, redline, or raised white letters. The right brand often comes down to the specific model and the look you want the car to have. Start with the correct size for the model, then narrow the field by sidewall appearance, speed rating, and rim-width compatibility.
What is the difference between Michelin Primacy 3 and BFGoodrich Radial T/A for a 1991 Audi in 205/60R15?
For a 1991 Audi using 205/60R15, the Michelin Primacy 3 is a blackwall radial with a 91W speed rating and a 5.5- to 7.5-inch rim-width range, while the BFGoodrich Radial T/A uses an RWL sidewall, carries a 90S speed rating, and also fits a 5.5- to 7.5-inch rim-width range. Weight is close, at 22 pounds for the Michelin and 23 pounds for the BFGoodrich.
The practical difference is less about fitment and more about presentation and speed category. The Michelin suits a more understated, modern blackwall appearance, while the BFGoodrich brings a distinctly period-performance American look through its raised white letters. On a 1991 Audi, that means the choice is usually visual and use-case driven after the size has already been confirmed.
Fitting & Setup
What rim width do 1991 Audi tires require?
Rim-width guidance is available for some 1991 Audi tire sizes. The 205/60R15 fits 5.5- to 7.5-inch rims in the available range, and the 215/60R15 fits either 5.5- to 7.5-inch or 6.0- to 7.5-inch rims depending on the specific tire. Those are both 15-inch tire sizes, while 175/70R14 remains a 14-inch fitment.
That makes wheel confirmation especially important for a 1991 Audi 200 Quattro, since that model appears with two different 15-inch sizes and not every tire within those sizes carries the same approved rim-width span. Measure the actual wheel or confirm the wheel specification before choosing the tire. Staying inside the tire maker’s approved width range helps preserve correct section shape and handling behavior.
Do 1991 Audi tires require inner tubes?
A tube requirement is only clearly marked on some 1991 Audi tires. The Michelin Primacy 3 in 205/60R15 is marked TL, which means tubeless. Other available 205/60R15, 215/60R15, and 175/70R14 products do not all carry the same tube marking, so tube status can vary by product and should be confirmed on the individual tire before installation.
For most 1991 Audi applications with original-style modern wheels, tubeless fitment is typical, but the tire’s own marking and the condition of the wheel still matter. If you are working with older wheels, refinished rims, or a specialty setup, confirm both the wheel’s suitability and the tire’s tube designation before mounting. That avoids making assumptions from size alone.
Maintenance, Storage & Longevity
How should I store a 1991 Audi when the tires are fitted?
A 1991 Audi should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber. Keep the tires properly inflated, avoid prolonged contact with standing moisture, and move the car occasionally so the same contact patch is not carrying the load month after month.
Because every 1991 Audi size here is radial, long static storage is generally less troublesome than with older bias-ply tires, but flat spotting and sidewall aging can still appear if the car sits for extended periods. If the car will be parked for a season, rolling it periodically or supporting it appropriately can help. A clean storage environment often adds as much life as low mileage does.
How long do tires on a 1991 Audi typically last?
On a low-use 1991 Audi, tire age usually matters more than tread wear. A good rule is to begin close inspection once a tire reaches about five to seven years of age and to treat around ten years as a serious replacement point, even if the tread still looks serviceable. The DOT date code on the sidewall is the easiest way to determine actual age.
That advice is especially important for collector-owned Audi sedans and coupes that spend much of their life parked, because old rubber can harden, crack, or lose wet-weather confidence long before the tread is gone. If your 1991 Audi still wears an older set with plenty of tread depth, age should still factor into your decision. Tire replacement is often about time and condition, not mileage alone.
How often should tires on a 1991 Audi be inspected?
Tires on a 1991 Audi should be checked before every drive and more carefully before any longer trip. Look for sidewall cracking, cuts, bulges, uneven wear, foreign objects in the tread, and any loss of pressure since the last outing. On cars that are driven infrequently, pressure and visual condition can change even while parked.
A more thorough inspection every few months is wise for a 1991 Audi that alternates between storage and occasional use. Pay attention to tread age, valve-stem condition, and whether the spare is still serviceable. Catching aging or damage early matters on an older European car, where a long drive can quickly expose weak spots that never showed up on short local outings.
Safety & Road Use
Are 1991 Audi tires safe for highway driving?
1991 Audi tires can be suitable for highway driving when the size, condition, and speed rating match the intended use. The available speed ratings include T at 118 mph for 175/70R14, S at 112 mph and W at 168 mph for 205/60R15, and S at 112 mph plus V at 149 mph for 215/60R15. All of the available sizes here are radial, which aligns well with the way 1991 Audis were designed to drive.
In real-world use, the tire’s rating is only part of the picture. A 1991 Audi also depends on healthy suspension parts, correct alignment, sound brakes, and proper inflation to feel secure at highway speeds. If the car is newly purchased or has spent time off the road, inspect the full chassis and braking system before assuming the tires alone determine roadworthiness.
What inflation pressure should I use for 1991 Audi tires?
Inflation pressure for a 1991 Audi should begin with the vehicle’s factory recommendation, then be cross-checked against the tire maker’s own pressure and load information for the exact size and product. Some available tires include load-at-pressure figures such as 1301 pounds at 35 psi or 1521 pounds at 32 psi for 205/60R15, and 1411 pounds at 35 psi or 1477 pounds for certain 215/60R15 products.
Those figures are not universal settings for every 1991 Audi tire, and they should not be transferred from one size to another. The correct running pressure depends on the exact model, axle load, and tire chosen. Use the owner’s manual or factory placard as the baseline for the car, then make sure the selected tire is being used within its own stated limits.
What should I check before taking a 1991 Audi on a longer drive?
Before a longer drive in a 1991 Audi, inspect all four tires and the spare for cracking, punctures, tread damage, bulges, and proper cold inflation. Check that the wheel hardware is secure, the valve stems are in good shape, and the tread is wearing evenly. Uneven wear can point to alignment or suspension issues that matter just as much as tire condition on an older Audi.
A longer-trip check should also include the rest of the car, especially on Quattro models and higher-end 200 or V8 cars that can conceal deferred maintenance. Confirm brake feel, steering response, fluid levels, and charging-system health along with tire condition. A 1991 Audi can be a very satisfying road car, but tire readiness works best as one part of a full pre-drive mechanical review.
