The 1980 Audi 4000 arrived at a time when compact European sedans were gaining a reputation for balanced road manners, efficient packaging, and a more refined driving feel than many economy cars of the era. For owners preserving one today, tire choice plays a big role in keeping that character intact. The 1980 Audi 4000 uses a 175/70R13 radial tire on a 13-inch rim, so the main decision is less about fitment variety and more about selecting the right tire within that size. Available choices center on radial construction, blackwall styling, and the Avon CR6ZZ series. That makes wheel condition, intended use, and overall period-appropriate appearance worth checking before mounting new tires.
Which Tire Size Is Right for The 1980 Audi 4000
The 1980 Audi 4000 uses one primary tire size: 175/70R13. That is a radial fitment for a 13-inch rim, and the same size carries across the covered Base sub-model, so the key choice becomes selecting the right tire style and product characteristics within that established size rather than sorting through multiple primary fitments.
A 175/70R13 size uses a 175-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 13-inch rim diameter. On the 1980 Audi 4000, that modern metric radial format matches the car's original-era European sizing approach and keeps tire selection straightforward. In this size, available choices include Avon in the CR6ZZ series with a blackwall sidewall treatment. This size is the place to focus if the goal is to maintain the car's intended proportions while also confirming wheel width, tire condition, and overall suitability for how the car will be driven.
Sub-model fitment is straightforward for the 1980 Audi 4000. The covered Base model uses the same primary tire size, which simplifies selection and shifts attention toward wheel compatibility, tire style, and overall condition.

Tire Size & Fitment
What tire size fits a 1980 Audi 4000?
The 1980 Audi 4000 uses a 175/70R13 tire size. This is a radial fitment and it is the primary size used for the covered model, including the Base sub-model, which makes the fitment picture much simpler than on vehicles that changed sizes by trim or wheel package.
Using the correct size is only the first step. It is still important to confirm that the car still has its 13-inch wheels, that wheel width falls within the tire's acceptable range, and that there are no old modifications affecting clearance. On a low-use vintage Audi, checking current tire age and wheel condition matters just as much as matching the printed size.
What size rim does a 1980 Audi 4000 use?
The 1980 Audi 4000 uses a 13-inch rim with its 175/70R13 tire fitment. The tire size itself confirms the wheel diameter, since the final number in the size designation identifies the rim diameter in inches for this metric radial format.
Rim diameter should be verified on the actual car before ordering tires, especially if the vehicle has changed hands several times or has seen aftermarket wheel swaps. A tire made for a 13-inch rim cannot be mounted on a different diameter wheel, and wheel width also deserves attention so the selected tire matches the wheel as well as the vehicle.
What does 175/70R13 mean on a 1980 Audi 4000?
On a 1980 Audi 4000, 175/70R13 means the tire has a nominal section width of 175 millimeters, a 70-series aspect ratio, radial construction, and a 13-inch rim diameter. It is a metric radial size, which suits the era and design character of this compact German sedan.
Understanding the size helps when comparing replacement tires, because each part of the code affects how the tire relates to the wheel and the car's overall stance. Staying with the same size keeps the fitment baseline consistent. If the Audi has replacement wheels or suspension changes, confirm those details first rather than assuming the size on the car now is automatically the right one.
Choosing the Right Tire
What should I consider when choosing a 175/70R13 tire for a 1980 Audi 4000?
Start with the established 175/70R13 size and radial construction, since that is the core fitment for the 1980 Audi 4000. From there, compare practical details such as rim-width compatibility, sidewall style, load and speed markings, and whether the tire's overall character suits a restoration-minded driver, occasional road use, or a more spirited vintage driving experience.
The wheel setup on the car deserves just as much attention as the tire itself. A collector car may no longer wear its original wheels, and an incorrect width can affect how well a tire sits and performs. Looking at the car's condition, intended use, and visual goals will usually narrow the choice more effectively than chasing a broad brand preference.
What sidewall styles are available for 1980 Audi 4000 tires?
For the 1980 Audi 4000 fitment shown here, the available sidewall style is blackwall. That gives the car a clean, understated presentation that suits many European sedans of the period and keeps the visual focus on the wheel and body lines rather than on stripe or whitewall detail.
Sidewall style affects appearance more than fitment, but it still matters on a preserved or restored car. A blackwall tire tends to look natural on an early-1980s Audi, especially if the goal is a subtle period-style presentation. Buyers who prioritize exact restoration appearance should also compare the tire's tread and overall profile with the look they want to achieve.
What brands offer tires for the 1980 Audi 4000?
The available tire brand in the 1980 Audi 4000's 175/70R13 fitment is Avon. The applicable product appears in the CR6ZZ series, giving owners a radial option in the correct size with a blackwall sidewall and specifications suited to a 13-inch wheel application.
Brand matters less than matching the right size, construction, and wheel compatibility for the actual car in front of you. A well-chosen 175/70R13 radial that suits the Audi's wheel width and intended use is more important than selecting by name alone. Looking closely at the series, fitment specs, and condition of the wheels will lead to a better decision.
Restoration & Appearance
Which tire should I choose for a period-style 1980 Audi 4000?
A period-style 1980 Audi 4000 should begin with the correct 175/70R13 radial size on the proper 13-inch rim. Keeping the right size and general construction is the most important step, because it preserves the car's intended proportions and avoids introducing an obviously mismatched modern fitment that can change the way the car sits visually.
Appearance decisions then come down to details such as sidewall treatment and the overall character of the tire. A blackwall radial generally suits the restrained European look of this Audi. If exact originality matters beyond period-style appearance, compare the tire's look with factory literature, marque-club references, or other model-specific restoration resources before making the final selection.
Does correct tire fitment matter for a 1980 Audi 4000 restoration?
Correct tire fitment matters on a 1980 Audi 4000 restoration because tire size has a strong effect on stance, wheel-well appearance, and the car's overall visual balance. Using the proper 175/70R13 radial size keeps the restoration grounded in the dimensions associated with the model rather than drifting into a generic replacement choice.
Fitment also influences how authentic the finished car feels on the road and at a glance. Even when a tire mounts successfully, a different size can alter the visual relationship between wheel and body. Restoration-minded owners should confirm wheel diameter, wheel width, and tire appearance together so the result supports both usability and the era-appropriate presentation of the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1980 Audi 4000?
Modifications can absolutely affect tire fitment on a 1980 Audi 4000, even when the intended tire size remains 175/70R13. Aftermarket wheels, changes in wheel width, suspension lowering, replacement springs, or bodywork differences can all influence clearance and how the tire sits relative to the fenders and steering components.
A car that has been altered should be measured and inspected before new tires are chosen. Confirm the actual wheel diameter and width on the vehicle, then check turning clearance and vertical space around the tire. On an older Audi, it is also worth looking for uneven suspension wear that could create rubbing or alignment issues once fresh tires are installed.
What should I inspect before driving a 1980 Audi 4000 on new tires?
Before driving a 1980 Audi 4000 on new tires, inspect the wheels for damage or corrosion, verify that the tire size matches the car's 175/70R13 fitment, and make sure the tires are mounted on compatible 13-inch rims. It is also wise to check valve stems, lug hardware, and basic alignment condition before putting road miles on the car.
The rest of the car deserves attention too, especially on a vehicle that may have spent long periods parked. Look over suspension bushings, shocks, steering components, and wheel bearings, then confirm tire pressures once the tires are installed. A short test drive followed by another visual check can catch rubbing, vibration, or air-loss issues before they become larger problems.
How should 175/70R13 tires on a collector 1980 Audi 4000 be maintained?
175/70R13 tires on a collector 1980 Audi 4000 should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Because older enthusiast cars are often driven less, tire condition can decline from age and environment even when tread wear looks minimal, so sidewall cracking, bulges, cuts, and persistent air loss should be watched closely.
Storage conditions matter almost as much as mileage. Keeping the Audi away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the rubber over time. It also helps to move the car periodically, inspect the tread and sidewalls before each outing, and recheck pressures before a longer drive rather than assuming a seldom-driven car is road-ready.
