1971 Audi Super Tires

The 1971 Audi Super uses two primary tire sizes: 165R13 in radial construction and 600-13 in bias-ply construction. Both sizes are built for 13-inch wheels, so the fitment question is less about wheel diameter and more about which construction and size format your car is actually set up to use.

A car that remains restoration-oriented may stay with 600-13, especially when traditional whitewall styling matters. A car already configured around radial use may be better matched to 165R13. Checking the tire size currently on the car, the wheel width, and any prior changes to wheels or suspension helps narrow the choice before selecting a replacement.

The 1971 Audi Super uses a 13-inch rim diameter with both of its primary tire sizes, 165R13 and 600-13. That shared rim diameter simplifies the first stage of fitment because both the radial and bias-ply options are centered around the same wheel diameter rather than separate wheel sizes.

Rim diameter is only part of the fitment picture, though. The available 165R13 radial products and 600-13 bias-ply products do not share the same rim-width ranges, so wheel width should be confirmed before changing construction. Owners working with older wheels should also inspect the wheel condition itself before road use, especially on a low-use collector car.

Yes. Both the 1971 Audi Super 90 and the 1971 Audi Super 90 Wagon use the same two primary tire sizes: 165R13 radial and 600-13 bias-ply. There is no covered sub-model split in which one uses a different diameter or a different primary tire size than the other.

That means sub-model identification is not the hard part here. The more important check is whether your specific car is equipped around the radial size or the bias-ply size, and whether it still has stock-style wheels or has been changed over time. On older imported cars, those details matter more than the sedan-versus-wagon distinction.

On the 1971 Audi Super, 600-13 is a bias-ply tire size. It uses the older numeric sizing format, and the available products in this size are bias-ply tires in BFGoodrich's Silvertown Classic Bias Ply series with narrow whitewall and wide whitewall sidewall treatments.

That matters because bias-ply construction affects both appearance and setup. A car wearing 600-13 tires may be aimed at a more traditional restoration look, while a driver-oriented car may instead use the radial 165R13 size or a radial equivalent. Before changing construction, check wheel width, overall tire dimensions, and clearance around the fenders and steering range.

Radial equivalents for 600-13 include 165R13 as an 80-series metric radial, P165/75R13 as a P-metric 75-series radial, and P175/70R13 as a P-metric 70-series radial. These are alternatives to the original bias-ply size, and they represent different radial sizing conventions rather than one single modern conversion path.

A recommended rim-width range of 4 to 5 inches applies when comparing these equivalents. That makes wheel width an important checkpoint before changing from 600-13 to a radial option. Owners should also compare the vehicle's available space at the suspension, steering, and body openings, since equivalent sizing still needs to be matched to the car's actual setup.

That depends on how the 1971 Audi Super is being used and presented. The primary bias-ply choice is 600-13, while the primary radial fitment is 165R13 and additional radial equivalents exist for 600-13. Bias-ply suits a more traditional period-style presentation, while radial choices align with a more modern small-car tire format.

Appearance goals are only part of the decision. The wheels need to be compatible with the tire you choose, and any conversion from one construction type to another should include checks for rim width, tire dimensions, and available clearance. A car that has been modified over the years deserves extra inspection before settling on either direction.

Start by confirming that your 1971 Audi Super is using the radial fitment rather than the 600-13 bias-ply setup. In 165R13, the available choices include Michelin and Dunlop, all in blackwall form, with tire series such as Michelin XAS-FF, Michelin XAS, and SP Sport Aquajet.

After size and construction are confirmed, compare the tire's intended character, rim-width compatibility, and any useful specification differences such as load information or overall product weight. For many owners, the real decision is whether the car should keep a classic European radial appearance or whether a more restoration-oriented bias-ply visual style is the better match.

The sidewall choices depend on which tire size and construction you select. The 165R13 radial options are blackwall tires, while the 600-13 bias-ply options are available with either a narrow whitewall or a wide whitewall. That creates a clear visual divide between the radial and bias-ply offerings.

Sidewall style affects the finished look of the car as much as the size itself. A blackwall radial gives the Audi a more understated European presentation, while the whitewall bias-ply choices move it toward a more traditional vintage appearance. The best match depends on whether the goal is road use with radial construction or a stronger period-style restoration character.

Tires for the 1971 Audi Super are available from Michelin, Dunlop, and BFGoodrich. Michelin and Dunlop cover the 165R13 radial fitment, while BFGoodrich covers the 600-13 bias-ply fitment through the Silvertown Classic Bias Ply series with whitewall variations.

Brand choice should follow the correct size and construction rather than lead the decision. Once the car's fitment path is clear, compare each brand's available series, sidewall style, rim-width suitability, and other relevant specifications. That approach keeps the selection focused on the Audi's actual wheel and tire setup instead of choosing by brand name alone.

For a period-style 1971 Audi Super, the 600-13 bias-ply tire is the more traditional starting point because it keeps the vintage numeric size format and bias-ply construction. The available BFGoodrich Silvertown Classic Bias Ply options also offer narrow whitewall and wide whitewall styling, which can shape the car's finished appearance.

A restoration-minded choice still needs to be matched to the car's actual wheels and intended use. Period-style does not automatically mean one whitewall width or one construction is historically exact for every car, so owners pursuing strict originality should compare against marque-specific references. For broader vintage presentation, the 600-13 bias-ply path is the most natural fit.

Tire construction changes the visual character of a restored 1971 Audi Super as well as its fitment language. A 600-13 bias-ply tire carries a more vintage presentation, especially with narrow whitewall or wide whitewall sidewalls, while a 165R13 radial gives the car a classic European blackwall look rooted in later radial-era styling.

That visual difference is often one of the biggest restoration decisions on a compact import from this period. Owners who want the car to read as more traditional may lean toward bias-ply, while owners emphasizing road use may prefer the radial format. The best result comes from balancing appearance goals with wheel compatibility and the car's overall restoration direction.

Yes. Even though the 1971 Audi Super uses 13-inch tire fitments, modifications can still affect whether a given tire setup is appropriate. Aftermarket wheels, altered wheel width, suspension changes, ride-height adjustments, or body repairs can all change the amount of space available for a radial or bias-ply tire.

That is especially important when moving from 600-13 to one of its radial equivalents or when switching between bias-ply and radial construction. A modified car should be checked for steering clearance, fender clearance, and wheel compatibility before new tires go on. Older vehicles are often changed over decades, so it pays to inspect the actual setup rather than assume it remains stock.

Before driving a 1971 Audi Super on new tires, inspect the wheels for condition and correct diameter, confirm the tire size and construction match the car's setup, and make sure inflation is appropriate for the tire being used. It also helps to verify that nothing is rubbing at the fenders, steering stops, or suspension points.

A low-use vintage car deserves a broader once-over before road use. Check for aged valve stems, wheel hardware condition, brake drag, and any suspension looseness that could affect how the tires track. After the first few miles, recheck inflation and look for any signs of uneven contact or unexpected clearance issues.

Collector-car tires on a 1971 Audi Super should be maintained with regular pressure checks, visual inspection, and careful storage habits. Whether the car is using 600-13 bias-ply tires or 165R13 radials, owners should watch for cracking, bulges, cuts, uneven wear, and gradual air loss that can go unnoticed on a lightly driven car.

Storage conditions matter just as much as mileage. Keeping the Audi away from prolonged sunlight, heat, moisture, and ozone sources helps preserve tire condition over time. It is also wise to inspect the tires before each driving season and before any longer trip, since age and inactivity can matter as much as tread depth on collector vehicles.
