The 1983 Audi 4000 came from a period when Audi was building a reputation for crisp European road manners, tidy packaging, and understated sport-sedan character. Whether kept as a clean survivor or maintained as a driver, this model rewards careful attention to details that preserve its balanced feel. The 1983 Audi 4000 uses a 175/70R13 radial tire on a 13-inch rim, and that same primary fitment carries across Base, GT, and S versions. Tire choice here is less about sorting through multiple factory sizes and more about selecting the right radial within that format, appearance, and rim-width range. For owners focused on proper stance, road use, and vintage character, getting the size and wheel match right matters.
Which Tire Size Is Right for The 1983 Audi 4000
The 1983 Audi 4000 uses one primary tire size: 175/70R13 radial on a 13-inch rim. That fitment remains consistent across the covered sub-models, so the main decision is not which size applies, but which tire best suits the car's intended use, visual presentation, and wheel compatibility within that size.
175/70R13 is a metric radial size in which 175 refers to the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 13 is the rim diameter in inches. On the 1983 Audi 4000, this modern metric radial format matches the car's period as a compact European sedan designed around radial-tire handling. Available choice within this size centers on an Avon CR6ZZ blackwall radial series. It is the size to stay with when the goal is preserving the car's intended proportions while confirming the wheel remains within the appropriate width range.
Tire fitment is straightforward across the 1983 Audi 4000 range because the covered sub-models share the same primary tire size. Checking the exact sub-model still helps confirm the car has not been altered with different wheels or a non-stock setup over time.

1983 Audi 4000 Base
The 1983 Audi 4000 Base uses the same 175/70R13 radial fitment as the rest of the covered range. That keeps tire selection focused on choosing the right radial product for wheel compatibility, road use, and the kind of traditional blackwall appearance that suits the car.
The 1983 Audi 4000 GT also uses 175/70R13 radial tires, so there is no separate primary size to sort out here. Selection comes down to staying with the correct metric radial format and confirming that the wheels on the car still match the expected 13-inch setup.
The 1983 Audi 4000 S shares the 175/70R13 radial size with the other covered sub-models. That makes the process simpler for owners, with attention shifting to tire series choice, wheel-width compatibility, and maintaining the car's intended stance and drivability.
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 1983 Audi 4000?
The 1983 Audi 4000 uses a 175/70R13 radial tire. That primary size applies across the covered Base, GT, and S sub-models, making fitment more straightforward than on vehicles that changed sizes by trim or package.
The practical step is confirming that the car still has its 13-inch wheel setup and has not been changed to aftermarket wheels over the years. Once the wheel diameter is verified, selection becomes a matter of choosing the right tire within 175/70R13 while checking wheel width, overall condition of the suspension, and clearances at full steering lock.
What size rim does a 1983 Audi 4000 use?
The primary tire fitment for the 1983 Audi 4000 is built around a 13-inch rim. That rim diameter matches the 175/70R13 tire size used across the covered sub-model range.
Rim diameter is only part of the fitment picture, so it is worth checking the actual wheel on the car before choosing tires. A 13-inch wheel still needs to be suitable in width for the tire being considered, and any previous wheel change can affect both tire choice and the car's stance, steering feel, and fender clearance.
Do all 1983 Audi 4000 sub-models use the same tire size?
Yes. The covered 1983 Audi 4000 Base, GT, and S sub-models all use the same 175/70R13 radial tire size. There is no separate primary size split among those sub-models here.
That shared fitment simplifies the search, but it is still smart to inspect the car itself before replacing tires. Older vehicles are often updated with different wheels, lowered suspension, or replacement rims from another application, and those changes can alter the size that physically works even when the original covered fitment remains 175/70R13.
Choosing the Right Tire
What should I consider when choosing a 175/70R13 tire for a 1983 Audi 4000?
Start with the correct size, 175/70R13, and confirm that the tire is a radial built for a 13-inch wheel. For the 1983 Audi 4000, that preserves the intended sizing format and keeps the search focused on tires that suit the car's proportions and road manners.
Beyond size, compare the tire's rim-width compatibility with the wheels currently on the car and think about how the Audi will be used. A lightly driven survivor, a restoration-minded street car, and a regularly exercised driver may all share the same size, but tire-series choice, sidewall appearance, and wheel match still shape the final decision.
What sidewall styles are available for 1983 Audi 4000 tires?
The available 175/70R13 product for the 1983 Audi 4000 uses a blackwall sidewall style. That gives the car a clean, understated look that fits the restrained European character many owners want to maintain.
Sidewall style matters because it changes the visual balance of the car even when the tire size stays the same. On a 1983 Audi 4000, a blackwall presentation keeps attention on the wheel design and body lines, so the decision becomes less about decorative sidewall treatments and more about choosing the right radial tire for the car's intended use.
What brands offer tires for the 1983 Audi 4000?
Avon offers a 175/70R13 tire for the 1983 Audi 4000 in the CR6ZZ series. That gives owners a focused option in the correct radial size rather than a broad mix of brands and constructions within this specific fitment.
With a narrow product set, the selection process shifts toward confirming wheel compatibility and deciding whether the tire's character suits the car's role. On an Audi 4000 that is kept close to its original presentation, staying with the correct size and a compatible radial construction matters more than trying to compare a large number of brand alternatives.
Restoration & Appearance
Which tire should I choose for a period-style 1983 Audi 4000?
A period-style approach for a 1983 Audi 4000 starts with the correct 175/70R13 radial size on the proper 13-inch wheel. Keeping the original sizing format intact does more for the car's stance and visual balance than chasing a dramatically different modern substitute.
Appearance is shaped by more than dimensions alone, so sidewall treatment and tire profile deserve attention as well. A blackwall radial suits the Audi's clean early-1980s look, while owners seeking strict originality should compare any final tire choice against marque literature, archival photos, or other vehicle-specific historical references before committing.
Does correct tire fitment matter for a 1983 Audi 4000 restoration?
Yes, correct tire fitment matters on a 1983 Audi 4000 restoration because tire size strongly affects stance, wheel-to-fender proportion, and the car's overall visual character. Staying with 175/70R13 helps preserve the sizing relationship the car was built around.
Fitment also affects how authentic the finished car feels on the road and at a glance. Even when a restoration is not concours-focused, the wrong diameter, mismatched wheel setup, or an unsuitable sidewall treatment can make the car look off. Verifying wheel size and choosing a tire that respects the original format keeps the result more coherent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1983 Audi 4000?
Yes. The 1983 Audi 4000 uses a 175/70R13 tire as its primary fitment, but wheel changes, altered ride height, suspension work, or body modifications can change what actually clears the car. That is especially important on older vehicles that may have seen decades of owner changes.
A car that still appears stock can still have different wheel width or offset than expected, so a quick inspection is worthwhile before replacing tires. Check the installed wheel diameter, wheel width, and clearance at the fender and steering components, then compare those realities to the tire being considered rather than assuming every surviving Audi 4000 remains unchanged.
What should I inspect before driving a 1983 Audi 4000 on new tires?
Before driving a 1983 Audi 4000 on new tires, inspect the wheels for damage, confirm the tire size matches the wheel, and look over suspension and steering components that influence alignment and clearance. It also helps to verify that lug hardware, valve stems, and overall wheel condition are ready for service.
Once the tires are mounted, monitor inflation pressure, check for any rubbing at full lock, and recheck balance and air retention after the first drives. An older Audi that has spent time parked can reveal issues only after returning to use, so watching for vibration, pull, or uneven wear early can prevent larger fitment or chassis problems.
How should 175/70R13 tires on a collector 1983 Audi 4000 be maintained?
Collector-car tire care for a 1983 Audi 4000 starts with proper inflation, regular visual inspection, and attention to age-related issues even when tread depth still looks good. The 175/70R13 tires should be checked for cracking, cuts, bulges, and signs of air loss whenever the car is brought out for use.
Storage conditions matter just as much on a lightly used car. Keeping the Audi away from prolonged sunlight, heat, moisture, and ozone sources helps protect the rubber, while occasional movement prevents long stationary periods on one contact patch. A careful inspection before longer drives is wise because collector vehicles often age differently than daily drivers.
