1976 Audi Fox Tires

The 1976 Audi Fox uses two radial tire sizes: 155R13 and 175/70R13. Both sizes are associated with the Fox Base and Wagon, and both are built for 13-inch rims. That means the car does not depend on a separate trim-level tire size split within the covered sub-models.

The practical next step is confirming which size is actually on the car now and whether the wheels match that setup. Many older cars have changed wheels or replacement tires over time, so checking the wheel width, current tire markings, and clearance around the suspension and fenders is more useful than assuming every Fox still carries its original-style fitment.

Both tire sizes used on the 1976 Audi Fox fit a 13-inch rim. That applies to the 155R13 Euro-metric radial and the 175/70R13 metric radial. The wheel diameter is consistent even though the two tire sizes use different sizing conventions.

Rim diameter is only one part of the fitment picture, so the wheel width still matters before choosing a tire. A 155R13 and a 175/70R13 do not ask the wheel to do exactly the same job, and the car may have aftermarket or replacement wheels that differ from earlier setups. Reading the wheel and tire markings together helps avoid ordering the right diameter in the wrong overall configuration.

On a 1976 Audi Fox, 155R13 is a Euro-metric radial tire size. The 155 refers to nominal section width in millimeters, the R indicates radial construction, and the 13 is the wheel diameter in inches. This format is common on smaller European cars of the period.

That size tends to appeal to owners who want the narrower, traditional look associated with many 1970s import sedans and wagons. It is still important to compare the actual wheel width and current tire setup on the car, especially if the Fox has spent years with replacement wheels or later metric sizes that can change both appearance and clearance.

Start with the correct size for the actual wheel setup on the car, since a 1976 Audi Fox may use either 155R13 or 175/70R13. Both are radial 13-inch fitments, but they differ in sizing format and overall presentation. Construction is straightforward here because the available fitments are radial rather than bias-ply.

After size, compare the tire’s intended character and wheel compatibility. A narrower 155R13 keeps a more traditional small-European-car look, while 175/70R13 follows a more modern metric convention. Brand, tire series, sidewall appearance, rim-width range, and the way the car is used for touring, show duty, or occasional local driving should shape the final choice.

The 1976 Audi Fox has tire options from Michelin, Dunlop, and Avon. Michelin and Dunlop appear in the 155R13 fitment, while Avon is available in 175/70R13. All of the available products for this application are blackwall radial tires.

Brand choice should follow the size and wheel setup first, not the other way around. Once the correct size is confirmed, the meaningful comparison becomes tire series, rim-width compatibility where stated, and whether the car is being kept closer to a stock-style European look or set up around a different road-use preference within the correct 13-inch radial fitment.

Three tire series appear for the 1976 Audi Fox: Michelin XAS-FF, Dunlop SP Sport Aquajet, and Avon CR6ZZ. The Michelin XAS-FF and Dunlop SP Sport Aquajet cover the 155R13 fitment, while the Avon CR6ZZ is offered in 175/70R13. Each stays within the Fox’s radial 13-inch theme.

Series names matter because they help separate period-oriented European fitments from more modern performance-flavored offerings in the same general application. The right choice depends on the tire size already matched to the car’s wheels, the look you want under the fenders, and whether the Fox is being refreshed as a stock-style driver or used in a more specialized enthusiast setting.

For a period-style 1976 Audi Fox, the narrower 155R13 often aligns more naturally with the compact European character the car carried when new. It uses a Euro-metric radial format that looks at home on a mid-1970s German sedan or wagon. Michelin and Dunlop both offer blackwall choices in that size.

A restoration-oriented decision should still begin with the actual wheels on the car, since many surviving Fox models have been changed over the years. If exact originality matters beyond general period style, compare the car’s present setup with marque-specific historical references and owner documentation. That approach helps separate a believable era-correct look from a later replacement size that simply happens to fit.

Correct tire fitment matters on a 1976 Audi Fox restoration because tire size strongly affects the car’s stance, visual balance, and overall character. Even when both 155R13 and 175/70R13 are legitimate fitments, they do not present the car in exactly the same way. The tire is one of the most visible finishing details on a compact classic.

A restoration-minded owner should think about more than just getting a 13-inch tire onto the wheel. Sidewall shape, overall width impression, and the difference between Euro-metric and later metric sizing can change how authentic the car feels. Verifying the wheels, measuring what is on the car now, and deciding whether the goal is preservation or a tasteful driver refresh leads to a more consistent result.

Yes, modifications can affect tire fitment on a 1976 Audi Fox even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, suspension lowering, replacement springs, or body repairs can alter how a 155R13 or 175/70R13 sits in the wheel opening. Small imported cars often have less extra room than larger classics.

A modified Fox should be checked at full steering lock and through normal suspension movement before settling on a tire. Wheel diameter may still be 13 inches, but width and offset changes can create rubbing that did not exist on the original setup. Looking at current clearances first is more reliable than choosing by size code alone.

Before driving a 1976 Audi Fox on new tires, inspect the wheels for damage, confirm the tire size matches the intended wheel setup, and make sure the tires are seated and inflated properly. It also helps to check steering components, wheel bearings, and suspension wear on an older front-wheel-drive car that may have sat for long periods.

A short local road test is the best next step after installation. Watch for rubbing, vibration, pulling, or uneven ride height, then recheck inflation and lug torque after the first miles. Collector-era cars often reveal old alignment issues only after fresh tires go on, so catching those early protects the new tires and makes the Fox more pleasant to drive.

Tires on a collector 1976 Audi Fox should be maintained with regular pressure checks, routine visual inspection, and attention to age-related condition as much as tread depth. A car that is driven only occasionally can still develop sidewall cracking, flat spotting, slow air loss, or internal deterioration long before the tread looks worn out.

Storage conditions matter just as much as mileage on a lightly used Fox. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the rubber, and moving the vehicle periodically can reduce long-term flat spotting. Before any longer drive, inspect the tread and sidewalls carefully and confirm the tires still suit the car’s present wheels and suspension condition.
