The 1991 Audi Coupe Quattro belongs to the era when Audi was firmly establishing all-wheel-drive performance coupes as serious enthusiast cars, blending crisp European styling with year-round road manners. It is a distinctive car today because buyers often want to preserve that balanced, driver-focused character rather than simply fill the wheel openings. The 1991 Audi Coupe Quattro uses a single primary tire size, 205/60R15, in radial construction on a 15-inch rim. Within that size, choices range from blackwall and raised white letter options to wide whitewall designs from several tire series. The real decision is choosing a tire that suits the car's appearance, intended use, and existing wheel setup.
Which Tire Size Is Right for The 1991 Audi Coupe Quattro
The 1991 Audi Coupe Quattro uses one primary tire size: 205/60R15. That is a radial size for a 15-inch wheel, and it is shared by the covered 20v sub-model, so the main decision is not sorting through multiple factory sizes but choosing the right tire style, series, and overall presentation within that fitment.
205/60R15 is a metric radial size in which 205 identifies the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. For the 1991 Audi Coupe Quattro, this size supports the car's modern-era handling character while keeping fitment centered on a 15-inch rim. Available choices include Michelin, American Classic, Coker Classic, and BFGoodrich, with blackwall, wide whitewall, and raised white letter sidewall styles. That gives owners room to stay close to a clean European look or choose a more distinctive vintage-inspired appearance.
Fitment is straightforward for the covered 1991 Audi Coupe Quattro sub-models because the tire size remains consistent. Checking the exact sub-model still matters, but tire selection here is mainly about choosing the right radial tire style and product character rather than sorting through multiple primary sizes.

1991 Audi Coupe Quattro 20v
The 1991 Audi Coupe Quattro 20v uses the same 205/60R15 radial fitment as the core model. That keeps the decision focused on selecting the right look and product type, whether the goal is a restrained blackwall presentation, a whitewall style, or a raised white letter option on the existing 15-inch wheels.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1991 Audi Coupe Quattro?
The 1991 Audi Coupe Quattro uses a 205/60R15 tire. It is a radial fitment, and the covered 20v sub-model uses the same primary size, so there is no separate alternate factory size to sort through on this page.
That makes tire selection more about choosing the right 205/60R15 product than deciding between multiple primary sizes. Before replacing tires, confirm that the car still has 15-inch wheels and has not been changed to a different wheel diameter, width, or offset, since those modifications can affect what will work safely and cleanly.
What size rim does a 1991 Audi Coupe Quattro use?
The primary tire fitment for the 1991 Audi Coupe Quattro is built around a 15-inch rim. The 205/60R15 size uses that 15-inch wheel diameter, which is the key wheel measurement that must match before any tire can be mounted.
Rim diameter should be confirmed first, but it is not the only wheel measurement that matters. Some available 205/60R15 products also call for a rim-width range, so it is wise to check the actual wheel width on the car, especially if the Coupe Quattro has aftermarket wheels or a prior owner changed the setup.
Does the 1991 Audi Coupe Quattro 20v use the same tire size?
Yes. The 1991 Audi Coupe Quattro 20v uses the same 205/60R15 radial tire size as the covered core fitment. That keeps the basic replacement decision simple because the sub-model does not introduce a second primary size.
Even with shared fitment, the best tire choice can still vary by how the car is used and how the owner wants it to look. A blackwall tire keeps a more understated appearance, while wide whitewall or raised white letter designs create a very different visual effect on the same 15-inch wheel package.
Choosing the Right Tire
What should I consider when choosing a 205/60R15 tire for a 1991 Audi Coupe Quattro?
Start with the correct size, which is 205/60R15, and make sure the tire matches the car's 15-inch wheel setup. From there, compare radial construction details, sidewall style, tire series, and any stated rim-width compatibility that applies to the product you are considering.
Appearance and intended use matter just as much on a car like this. A Michelin blackwall keeps the look subtle and modern, while wide whitewall and raised white letter options change the car's visual character considerably. Checking wheel width, load figures, and the condition of the suspension helps narrow the choices sensibly.
What sidewall styles are available for 1991 Audi Coupe Quattro tires?
The available 205/60R15 tires for a 1991 Audi Coupe Quattro include blackwall, wide whitewall, and RWL sidewall treatments. RWL means raised white letter, which gives the tire a more performance-oriented visual presence than a plain blackwall sidewall.
That sidewall choice has a strong effect on the finished look of the car even when the size stays the same. Blackwall suits a restrained European presentation, wide whitewall leans into a custom or nostalgic appearance, and raised white letters create a more assertive period-style contrast on the 15-inch wheel.
What brands offer tires for the 1991 Audi Coupe Quattro?
205/60R15 tires for the 1991 Audi Coupe Quattro are available from Michelin, American Classic, Coker Classic, and BFGoodrich. Those options cover several tire series and visual styles while staying within the same primary size and radial construction category.
Choosing among brands is usually less about declaring a single winner and more about matching the product to the car. Compare the sidewall treatment, tire series, rim-width guidance where shown, and load specifications where stated. That approach helps balance the Coupe Quattro's appearance goals with practical wheel compatibility.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Audi Coupe Quattro?
A period-style choice for a 1991 Audi Coupe Quattro starts with the correct 205/60R15 radial size on a 15-inch wheel. From there, the look can move in different directions, from a clean blackwall presentation to a more specialized raised white letter or wide whitewall appearance.
The best selection depends on whether the goal is a restrained factory-inspired look or a more personalized vintage-style presentation. Exact originality claims should be checked against marque-specific documentation and surviving reference cars, because sidewall treatment can influence the car's appearance almost as much as the wheel design itself.
How does tire construction affect the appearance of a restored 1991 Audi Coupe Quattro?
For the 1991 Audi Coupe Quattro, construction changes are not the main appearance issue because the primary fitment is already radial. The more noticeable visual differences come from the tire series and sidewall style chosen within the 205/60R15 size, especially blackwall, wide whitewall, or raised white letter designs.
A restored car can look understated or dramatically different depending on that sidewall choice, even when the wheel diameter and tire size remain correct. Owners aiming for a restoration-oriented result usually benefit from viewing the tire as part of the whole visual package, alongside wheel finish, ride height, and overall vehicle presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Audi Coupe Quattro?
Yes. Even though the primary tire size is 205/60R15, modifications can change what works on a 1991 Audi Coupe Quattro. Aftermarket wheels, altered wheel offset, suspension changes, lowered ride height, or bodywork differences can all affect clearance and overall fitment.
A car that still has its original-style 15-inch setup is much easier to match, while a modified example needs closer inspection before replacement. Check wheel width, steering clearance, inner fender space, and suspension condition before choosing a tire, especially if the current wheel and tire package does not match stock-type dimensions.
What should I inspect before driving a 1991 Audi Coupe Quattro on new tires?
Inspect the wheels for correct diameter and condition, then check valve stems, air pressure, and basic clearance once the new 205/60R15 tires are mounted. It is also smart to look over tread seating, sidewall condition, and any sign that the tire is contacting suspension or body components.
A collector or occasional-use Audi can hide problems that are easy to miss when the car sits for long periods. A short initial road test, followed by a second pressure and clearance check, helps catch rubbing, vibration, or unusual wear early before the Coupe Quattro is taken on regular drives.
How often should tires on a 1991 Audi Coupe Quattro be inspected?
Tires on a 1991 Audi Coupe Quattro should be inspected regularly, not just when tread looks worn. A car that sees occasional use should have its tires checked before driving and again after longer periods of storage for cracking, bulges, cuts, pressure loss, and uneven wear.
Age and inactivity can matter as much as mileage on an enthusiast car from this era. Keeping the tires properly inflated, storing the car away from prolonged heat and sunlight, and watching for slow air loss helps preserve both safety and ride quality. Any suspicious condition deserves closer evaluation before road use.
