The 1991 Audi 80 Quattro belongs to the era when Audi had firmly established its reputation for refined all-weather performance, understated design, and sure-footed Quattro traction in a compact executive sedan. Buyers looking after one today are often balancing everyday drivability with a clean, period-appropriate presentation. This exact model uses a 175/70R14 radial tire on a 14-inch rim, so the fitment question is fairly straightforward. The main choice within that size is the available radial tire style, including a narrow whitewall treatment rather than a plain modern blackwall look. For restoration-minded ownership or regular road use, the focus is on matching the correct size and keeping wheel, clearance, and overall condition in check.
Which Tire Size Is Right for The 1991 Audi 80 Quattro
The 1991 Audi 80 Quattro uses one primary tire size: 175/70R14, and it is a radial fitment for a 14-inch wheel. The covered Base sub-model uses that same size, so the decision is less about sorting through multiple factory fitments and more about choosing the right tire style within the correct size and wheel setup.
175/70R14 is a metric radial size where 175 identifies the nominal section width in millimeters, 70 is the aspect ratio, R designates radial construction, and 14 is the wheel diameter in inches. On the 1991 Audi 80 Quattro, this is the primary road-going fitment and it suits the car’s more modern tire sizing era rather than older bias-ply conventions. Available choices in this size include a Travelstar UN106 radial with a narrow whitewall sidewall treatment. Selecting this size keeps the fitment centered on the proper wheel diameter while leaving room to decide how period-minded or understated the finished look should be.
Tire fitment is straightforward across the covered 1991 Audi 80 Quattro sub-models. The Base model uses the same primary size, so the key is confirming the existing wheel setup and then choosing the tire style that best matches the car’s use and appearance goals.

1991 Audi 80 Quattro Base
The 1991 Audi 80 Quattro Base uses the same 175/70R14 radial fitment as the core model. That makes tire selection more about staying with the correct 14-inch sizing and choosing the available sidewall presentation than sorting through multiple sub-model-specific sizes.
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.
Best 1991 Audi 80 Quattro Tires for Sale

Owners of a 1991 Audi 80 Quattro usually want clear answers on the correct 175/70R14 size, 14-inch wheel fitment, available radial tire choices, appearance differences, and the checks that matter before putting a collector-era Audi back on the road.
Tire Size & Fitment
What tire size fits a 1991 Audi 80 Quattro?
The 1991 Audi 80 Quattro uses a 175/70R14 tire size. That is a metric radial size, and it is the primary fitment for this model, including the covered Base sub-model, so the starting point is matching that exact size rather than sorting through multiple original fitment options.
Once the size is confirmed, the next step is making sure the car still has the correct 14-inch wheels and a stock-compatible setup. If the car has had wheel, suspension, or ride-height changes over the years, it is worth checking actual wheel dimensions and clearance before selecting a replacement tire.
What size rim does a 1991 Audi 80 Quattro use?
The primary tire fitment for a 1991 Audi 80 Quattro is built around a 14-inch rim diameter. That comes directly from the 175/70R14 size designation, where the final number identifies the wheel diameter the tire is made to mount on.
Rim diameter is the first wheel measurement to verify, but it should not be the only one. A car that has been updated with aftermarket wheels may still use a 14-inch diameter while differing in width or offset, and those changes can affect how a replacement tire sits and clears the suspension and body.
Does the 1991 Audi 80 Quattro Base use the same tire size?
Yes. The 1991 Audi 80 Quattro Base uses the same 175/70R14 radial tire size as the core model. That makes fitment relatively simple, because there is not a separate tire size to sort out for the covered Base version.
Even with shared fitment, condition and setup still matter. A Base model with original-style wheels is a straightforward match, while one with replacement wheels or suspension changes deserves a closer look at wheel dimensions, tire age, and available clearance before putting a new set into regular road service.
Choosing the Right Tire
What should I consider when choosing a 175/70R14 tire for a 1991 Audi 80 Quattro?
Start with the correct 175/70R14 size and radial construction, since that is the primary fitment for the 1991 Audi 80 Quattro. After that, the decision shifts to details such as sidewall appearance, tire series, and whether the tire suits a more original-looking presentation or a simpler driver-oriented replacement approach.
Wheel compatibility still matters, especially on an older car that may no longer have its original wheels. It also helps to inspect how the car will be used, whether for occasional shows, weekend driving, or regular road miles, because those goals often determine whether appearance or a more understated replacement style takes priority.
What sidewall styles are available for 1991 Audi 80 Quattro tires?
The available 175/70R14 tire for the 1991 Audi 80 Quattro uses a narrow whitewall sidewall style. That gives the car a more distinctive and slightly more traditional look than a plain blackwall, while still staying within the correct modern radial size for this model.
Sidewall choice mainly affects presentation, so it is worth stepping back and deciding how the car should look when finished. A narrow whitewall can complement a well-kept period sedan nicely, but it should still be chosen only after confirming the tire size, wheel diameter, and overall fitment are right for the car.
What brands offer tires for the 1991 Audi 80 Quattro?
The available tire option for the 1991 Audi 80 Quattro in 175/70R14 comes from Travelstar. It is part of the UN106 series and uses radial construction, so the current brand choice is straightforward rather than spread across multiple makers in this exact fitment selection.
With a single brand option in view, the comparison becomes less about brand-to-brand differences and more about whether the size, wheel diameter, and sidewall appearance match the car and the owner’s goals. That is especially important on a collector-era Audi where visual character and proper fitment often matter as much as simple replacement.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Audi 80 Quattro?
A period-style starting point for a 1991 Audi 80 Quattro is the correct 175/70R14 radial size on a 14-inch wheel. Since this car comes from a modern radial era, staying with that sizing format preserves the overall fitment character better than trying to force an older-looking tire type onto the car.
Appearance then comes down to sidewall treatment and the overall look you want from the finished car. For exact originality questions, especially in a detailed restoration, marque references and vehicle-specific documentation are worth consulting so the final choice supports both the car’s presentation and its intended use.
Does correct tire fitment matter for a 1991 Audi 80 Quattro restoration?
Yes, correct tire fitment matters because tire size strongly affects how a restored 1991 Audi 80 Quattro sits, looks, and drives. Using the proper 175/70R14 radial size keeps the wheel diameter relationship in the right range and avoids introducing an obviously mismatched modern fitment.
Fitment also influences the finished stance and visual balance of the car. Even a clean restoration can look off if the tire size or sidewall style is out of character, so it pays to verify the wheel setup carefully and choose a tire that supports the Audi’s restrained early-1990s appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Audi 80 Quattro?
Yes. A 1991 Audi 80 Quattro may have originally used 175/70R14 tires, but modifications can change what actually fits the car today. Wheel width, offset, suspension height, spring changes, and prior body or brake work can all influence clearance even when the tire size itself sounds correct.
The safest approach is to inspect the car as it sits now rather than assuming every example remains stock. Measuring the installed wheel diameter and looking closely at steering, strut, and fender clearance helps prevent surprises, especially on a Quattro that may have seen decades of owner updates or replacement parts.
What should I inspect before driving a 1991 Audi 80 Quattro on new tires?
Before road use, inspect the wheels for correct diameter and condition, then check the suspension, alignment condition, and basic clearances around the tires. It also makes sense to confirm there are no rubbing points at full steering lock and no obvious issues such as damaged wheels, loose hardware, or uneven old tire wear patterns.
A collector-era Audi can spend long periods parked, so general vehicle condition matters as much as the new tires themselves. Looking over wheel bearings, brake condition, valve stems, and inflation before the first drive helps ensure the new 175/70R14 tires are being put into service on a sound and properly prepared chassis.
How should 175/70R14 tires on a collector 1991 Audi 80 Quattro be maintained?
Maintain 175/70R14 tires on a 1991 Audi 80 Quattro with regular pressure checks, visual inspections, and attention to age even if tread still looks healthy. Collector cars often accumulate fewer miles, so cracking, flat spotting, or age-related deterioration can become a bigger concern than simple tread wear.
Storage habits also make a difference. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps protect the sidewalls, and moving or driving the car periodically can reduce long-term standing stress. Any sign of bulges, cuts, persistent air loss, or unusual wear deserves prompt inspection before further road use.
