The 1981 Porsche 924 sits in an interesting place in Porsche history, blending the brand’s transaxle balance and tidy proportions with a driving character that still appeals to owners who enjoy lightweight, responsive sports cars. Tire choice matters on this car because fitment can vary by sub-model and wheel package, with 14-, 15-, and 16-inch rim diameters all appearing on the 1981 Porsche 924. Every primary fitment here is radial, but the available tires range from traditional blackwall sport-touring styles to wide whitewall options and more performance-oriented series. The right choice starts with confirming the exact sub-model and wheel size, then matching the tire’s look and intended road use to the car.
Which Tire Size Is Right for The 1981 Porsche 924
The 1981 Porsche 924 uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel setup. These sizes are all radial, but they span 14-, 15-, and 16-inch rims, so the first step is confirming both the specific 924 configuration and the actual wheel diameter on the car before comparing brands, sidewall styles, or tire series.
185/70R14 is a metric radial size: 185 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 14 is the rim diameter in inches. On the 1981 Porsche 924, this size is part of the fitment used on Base models and cars with aluminum wheels. Available choices include blackwall sport and classic radial designs from Avon, Dunlop, Michelin, and Vredestein, along with a wide whitewall BFGoodrich Silvertown Radial. It is a useful size for owners who want to stay with the 14-inch wheel setup while choosing between sporting character and a more distinctive appearance.
205/60R15 is a wider metric radial size, with a 205-millimeter section width, 60-series profile, radial construction, and a 15-inch rim diameter. This size is used on certain 1981 Porsche 924 Base models and versions equipped with aluminum wheels, so it should not be assumed across every 924 configuration. Product choices include blackwall and raised white letter styles, plus wide whitewall offerings, with options from Michelin, American Classic, Coker Classic, and BFGoodrich. It suits owners who have the 15-inch setup and want to compare a more performance-minded presentation against a more custom or traditional sidewall treatment.
185/70R15 follows the same metric radial format, using a 185-millimeter section width, 70-series profile, and a 15-inch wheel diameter. On the 1981 Porsche 924, this size belongs to the Turbo fitment group, making it a sub-model-specific choice rather than a universal 924 size. The available tires center on blackwall performance and classic touring styles from Michelin, Dunlop, and Avon, with a wide whitewall BFGoodrich Silvertown Radial also offered in this size. It is the right size to evaluate when a 924 Turbo still runs its 15-inch wheel arrangement and the goal is balancing correct fitment with appearance preference.
205/55R16 is a modern metric radial size with a 205-millimeter nominal width, 55-series profile, radial construction, and a 16-inch rim diameter. This size appears with the 1981 Porsche 924 Turbo and should be matched carefully to that wheel diameter before any product comparison begins. Most choices in this size are blackwall performance-oriented tires from BFGoodrich and Michelin, though a wide whitewall American Classic Radial is also available for a very different visual effect. It makes sense for owners whose Turbo is set up on 16-inch wheels and who want to choose between a sporty road-going look and a more customized presentation.
Sub-model fitment on the 1981 Porsche 924 is not one-size-fits-all. Base, Turbo, and w/aluminum wheels configurations use different combinations of tire size and wheel diameter, so confirming the exact version of the car is the key first step before narrowing the tire choices.

1981 Porsche 924 Base
The 1981 Porsche 924 Base uses two radial fitment paths, one on a 14-inch rim and another on a 15-inch rim. That makes wheel confirmation especially important before comparing available blackwall, wide whitewall, or raised white letter tire choices.
The 1981 Porsche 924 Turbo uses 15-inch and 16-inch radial fitments, distinct from the Base setup. Tire selection here starts with confirming which wheel diameter is actually on the car, then comparing the more performance-oriented blackwall options against any appearance-driven alternatives.
The 1981 Porsche 924 w/aluminum wheels follows the same two radial size paths used on the Base configuration. The practical decision is less about construction and more about verifying whether the car is on 14-inch or 15-inch wheels before choosing a tire series or sidewall style.
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 1981 Porsche 924?
A 1981 Porsche 924 can use 185/70R14, 205/60R15, 185/70R15, or 205/55R16, depending on the exact sub-model and wheel setup. Base models and cars listed with aluminum wheels use 185/70R14 or 205/60R15, while the 924 Turbo uses 185/70R15 or 205/55R16.
The practical question is not just width and profile, but which wheel diameter is actually on the car. Many older sports cars have had wheel changes over the years, so checking the current rim size and then matching the tire to that setup is the safest way to narrow the correct choice.
What size rim does a 1981 Porsche 924 use?
The 1981 Porsche 924 appears with 14-inch, 15-inch, and 16-inch rim diameters, depending on the sub-model and tire size being used. The 14-inch fitment corresponds with 185/70R14, the 15-inch fitments correspond with 205/60R15 and 185/70R15, and the 16-inch fitment corresponds with 205/55R16.
That makes wheel verification essential before selecting any tire. A buyer should confirm the diameter stamped on the wheel or compare the current tire size on the car, especially if the 924 has been updated with aftermarket wheels or a different Turbo-style setup over time.
Do all 1981 Porsche 924 sub-models use the same tire size?
No. The 1981 Porsche 924 does not use one universal tire size across all covered sub-models. Base models and the w/aluminum wheels version share 185/70R14 and 205/60R15 fitments, while the 924 Turbo uses a different pair of sizes: 185/70R15 and 205/55R16.
That difference matters because the tire decision starts with the exact version of the car, not just the model name. Even when two sizes seem close in overall dimensions, they are tied to different rim diameters, so identifying the sub-model and checking the current wheel package should come before comparing tire series or sidewall style.
Choosing the Right Tire
What should I consider when choosing a 1981 Porsche 924 tire?
Start with the correct primary size for the exact 1981 Porsche 924 configuration, then compare the tire’s intended character. Some available options lean toward classic blackwall sport-touring use, while others add appearance-driven choices such as wide whitewall or raised white letter sidewalls in certain sizes.
The next step is matching the tire to the car’s actual wheels and how the car is used. A frequently driven 924, a more original-style weekend car, and a customized car can all point toward different tire series, provided the wheel diameter and compatible rim-width range are checked first.
What sidewall styles are available for 1981 Porsche 924 tires?
Sidewall choices for 1981 Porsche 924 tires include blackwall, wide whitewall, and raised white letter styles, depending on the tire size. Blackwall is the most common presentation across the four fitments, while wide whitewall appears in several sizes and raised white letter is available in 205/60R15.
That variety gives the car a very different look without changing the basic fitment category. A buyer focused on a restrained sports-car appearance will usually gravitate toward blackwall options, while a more personalized or restoration-inspired visual direction may make the whitewall or lettered sidewall choices more appealing.
What brands offer tires for the 1981 Porsche 924?
Tires for the 1981 Porsche 924 are available from BFGoodrich, Michelin, Avon, Dunlop, Vredestein, American Classic, and Coker Classic, depending on the size. Brand availability changes by fitment, so the 14-, 15-, and 16-inch tire choices do not all offer the same mix of series or sidewall styles.
The useful comparison is not brand name alone, but what each brand offers within the needed size. Once the correct fitment is confirmed, compare tire series, sidewall appearance, compatible rim-width range where shown, and the kind of road use or presentation the 924 owner has in mind.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Porsche 924?
A period-style 1981 Porsche 924 usually starts with the correct primary tire size for the specific sub-model and wheel diameter, then narrows to a tire series with an appearance that suits the car’s era. In these fitments, blackwall classic sport radials are the most natural starting point for a traditional 924 presentation.
Some owners may prefer wide whitewall or raised white letter styling for a more personalized look, but those choices change the visual character of the car. When exact originality matters, the best path is to confirm the size first and then compare period photos, marque-club guidance, and restoration references before selecting the final sidewall style.
How does tire construction affect the appearance of a restored 1981 Porsche 924?
On the 1981 Porsche 924, all primary fitments are radial, so the appearance differences come more from tire series and sidewall treatment than from choosing between bias-ply and radial construction. Blackwall radials keep the visual emphasis closer to a traditional European sports-car look, while wide whitewall or raised white letter designs create a more stylized presentation.
That means a restoration-minded buyer should think about how much of the car’s original character to preserve visually. Even within the correct size, tread style, shoulder shape, and sidewall treatment can shift the finished look, so appearance should be weighed alongside wheel diameter, proper fitment, and intended driving use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Porsche 924?
Yes. Modifications can affect tire fitment on a 1981 Porsche 924 even when the tire size itself is correct for a covered sub-model. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body and fender changes can all influence how a 14-, 15-, or 16-inch tire package sits on the car.
That is especially important on a sports car with multiple factory-style fitment paths. A buyer should confirm the current wheel diameter first, then inspect for steering clearance, inner-fender space, and any evidence that the car has moved away from its original wheel and suspension setup.
What should I inspect before driving a 1981 Porsche 924 on new tires?
Before driving a 1981 Porsche 924 on new tires, inspect the wheels for correct diameter and condition, confirm the tire size matches the car’s setup, and look over the suspension and steering for anything that could affect clearance. Lug hardware, valve stems, and general wheel integrity should also be checked.
A short test drive should include attention to rubbing, vibration, and straight-line behavior. It also helps to recheck inflation pressure after installation and confirm that no old alignment or suspension issue is being masked by fresh tires, especially on a collector car that may have spent long periods parked.
How should tires on a collector 1981 Porsche 924 be maintained?
Tires on a collector 1981 Porsche 924 should be maintained with regular pressure checks, routine visual inspection, and attention to age-related condition as well as tread depth. Sidewall cracking, cuts, bulges, flat spotting, and slow air loss are all worth watching closely on a low-use sports car.
Storage habits matter nearly as much as mileage on a car like this. Keeping the 924 away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and occasional movement of the car can reduce set-in-place wear patterns that often show up on lightly driven collector vehicles.
