The 1989 Porsche 944 sits at an interesting point in the transaxle Porsche story, blending balanced handling with a more mature late-1980s performance character. By this stage, the 944 range included distinct Base, S2, and Turbo configurations, and tire fitment became more configuration-specific than on many earlier sports cars. This model uses radial tires, with 15-inch and 16-inch fitments depending on the exact version and axle position. That creates meaningful choice not just in size, but also in sidewall style, tire series, and whether the car is being kept visually period-minded or set up for more modern road use. The key is matching the tire to the exact sub-model, wheel diameter, and front or rear application.
Which Tire Size Is Right for The 1989 Porsche 944
The 1989 Porsche 944 uses four primary tire sizes, and the right one depends on the exact sub-model, wheel diameter, and in some cases whether the tire is mounted at the front or rear. Because this car uses both 15-inch and 16-inch fitments, the first step is confirming the wheel size already on the car, then matching that to the correct Base, S2, or Turbo application before comparing tire choices.
215/60R15 is a metric radial size that indicates a 215-millimeter nominal section width, a 60-series profile, and fitment on a 15-inch rim. On the 1989 Porsche 944, this size is used on the Base model and represents the 15-inch fitment within the lineup. Available choices include blackwall, wide whitewall, and redline sidewall treatments from brands such as American Classic, BFGoodrich, Dunlop, Avon, and Vredestein across series like Sport Classic, CR6ZZ, Sprint Classic, Radial T/A, and asymmetrical tread designs. It is the size to evaluate when the car retains its 15-inch wheel setup and the goal is balancing appearance with intended road use.
205/55R16 is a metric radial size with a 205-millimeter nominal width, a 55-series aspect ratio, and a 16-inch rim diameter. On the 1989 Porsche 944, this size appears in front fitment use on the S2 and also in some Turbo front applications. Product choices are largely blackwall performance-oriented radials from BFGoodrich and Michelin, though a wide whitewall option is also available from American Classic. This size should be considered only after confirming the car's exact 16-inch front-wheel setup, since the 944 range does not use one universal 16-inch tire across every version.
225/50R16 is a metric radial size that uses a 225-millimeter nominal width, a 50-series profile, and a 16-inch wheel diameter. On the 1989 Porsche 944, it appears as the rear size for the S2 and also in certain Turbo front and rear applications, making it one of the more versatile 16-inch fitments in the range. Available options include blackwall radial performance tires from BFGoodrich and Michelin in g-Force and Pilot Sport series. It is a size that deserves careful placement by axle and sub-model, especially on cars using staggered fitments or non-original wheel setups.
245/45R16 is a metric radial size indicating a 245-millimeter nominal section width, a 45-series profile, and fitment on a 16-inch rim. On the 1989 Porsche 944, this size is used in Turbo rear applications where a wider rear tire may be part of the car's setup. Its meaning is straightforward, but the fitment implication is more specialized because not every 16-inch 944 wheel or axle position uses this width. This is the size to confirm carefully against the rear wheel and overall vehicle configuration before moving into a product decision.
Sub-model fitment on the 1989 Porsche 944 is not one-size-fits-all. The Base model uses a 15-inch tire, while S2 and Turbo configurations move into 16-inch radial fitments that can also vary by front and rear position, so identifying the exact version matters before choosing a tire.

1989 Porsche 944 Base
The 1989 Porsche 944 Base uses a single 15-inch radial fitment, which makes size selection more straightforward than on the S2 or Turbo. The real choice here is among available tire styles, brands, and sidewall treatments that suit either a more period-style presentation or a modern road-use focus.
The 1989 Porsche 944 S2 Front uses a 16-inch radial front tire fitment that differs from the Base model's 15-inch setup. Tire selection should stay focused on the front application, with attention to wheel size and how the chosen tire complements the matching rear fitment.
The 1989 Porsche 944 S2 Rear uses a 16-inch radial rear tire size that is wider than the S2 front fitment. That makes rear tire selection a matter of matching the intended axle position correctly rather than simply choosing any 16-inch 944 tire.
The 1989 Porsche 944 Turbo Front can use more than one 16-inch radial size, so the exact wheel setup on the car should be confirmed before selecting a tire. This is especially important on Turbos that may have had wheel changes over time or that use staggered front-to-rear sizing.
The 1989 Porsche 944 Turbo Rear also has more than one 16-inch radial rear fitment possibility, including a wider rear option. Rear tire selection should follow the actual wheel and axle setup on the car so section width and profile stay consistent with available clearance.
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 1989 Porsche 944?
The 1989 Porsche 944 uses several radial tire sizes depending on the exact version and axle position: 215/60R15, 205/55R16, 225/50R16, and 245/45R16. The Base model uses 215/60R15, while S2 and Turbo fitments move into 16-inch sizes, with front and rear applications separated on some configurations.
That means the first step is confirming whether the car is a Base, S2, or Turbo and then checking the wheel diameter already on the car. A 15-inch Base setup calls for a different tire decision than a 16-inch S2 or Turbo, and front-to-rear placement matters on cars with staggered sizing.
What size rim does a 1989 Porsche 944 use?
The 1989 Porsche 944 uses either a 15-inch or 16-inch rim depending on the sub-model and tire size. The Base model uses a 15-inch rim with 215/60R15 tires, while S2 and Turbo configurations use 16-inch rims with 205/55R16, 225/50R16, or 245/45R16 tire sizes.
Wheel diameter is the first fitment detail to verify before looking at tire brands or sidewall styles. Once the rim diameter is confirmed, it becomes much easier to narrow the correct size, then compare rim-width compatibility and axle placement so the tire matches the car's actual setup.
Why does the 1989 Porsche 944 have more than one tire size?
More than one tire size appears on the 1989 Porsche 944 because the model range includes different configurations and, in some cases, different front and rear tire applications. The Base, S2, and Turbo do not all share the same wheel-and-tire arrangement, and some Turbo fitments use alternate 16-inch sizes.
That variation means the correct choice is tied to the exact version of the car, not just the model name on the title. Checking the sub-model, wheel diameter, and whether the tire is for the front or rear helps prevent choosing a size that belongs to another 944 configuration.
Choosing the Right Tire
What should I consider when choosing a 215/60R15 tire for a 1989 Porsche 944?
A 215/60R15 tire for a 1989 Porsche 944 should first match the Base model's 15-inch wheel setup. After size is confirmed, the main differences come down to the tire's series, sidewall style, rim-width specification, and whether the car is being kept closer to a traditional appearance or used in a more performance-oriented way.
This size is available in blackwall, wide whitewall, redline, and raised white letter form, so appearance can change significantly even when the dimensions stay the same. Comparing rim-width range, load information where given, and the intended role of the car helps narrow the right option without straying from the proper size.
What sidewall styles are available for 1989 Porsche 944 tires?
Sidewall style depends on the tire size chosen for the 1989 Porsche 944. Across the available fitments, blackwall is the most common presentation, while the 215/60R15 Base size also appears in wide whitewall, redline, and raised white letter form, and 205/55R16 includes both blackwall and wide whitewall options.
That makes sidewall choice less about fitment and more about the look the car is meant to carry. A traditional or restoration-minded presentation may point toward whitewall or redline in the sizes that offer them, while many S2 and Turbo buyers will likely focus on blackwall performance-style radials.
What brands offer tires for the 1989 Porsche 944?
Available brands for 1989 Porsche 944 tire sizes include American Classic, BFGoodrich, Dunlop, Avon, Vredestein, and Michelin. Brand availability changes by size, with the 215/60R15 fitment offering the broadest mix, while the 16-inch sizes are centered more heavily on BFGoodrich and Michelin depending on the exact application.
Brand should be compared alongside the actual size, tire series, and sidewall treatment rather than treated as a shortcut to the decision. Once the correct fitment is confirmed, the more useful comparison points are rim-width compatibility, visual style, and whether the tire suits the way the car will be driven and presented.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Porsche 944?
A period-style 1989 Porsche 944 tire starts with the correct size for the exact version of the car, then moves to the visual character of the tire itself. On a Base model with 215/60R15 fitment, choices include blackwall, redline, wide whitewall, and raised white letter options, while 16-inch applications lean more toward blackwall performance-style radials.
For an appearance-led restoration, the best approach is to match the tire's look to the wheel design and the era the car is meant to represent. When exact originality matters, marque-specific references and historical vehicle documentation are the right final check before settling on a sidewall treatment or series.
How does tire construction affect the appearance of a restored 1989 Porsche 944?
On the 1989 Porsche 944, the primary fitments are radial tires, so the construction itself already aligns with the car's late-1980s character. Appearance differences come more from profile, sidewall style, and tire series than from choosing between bias-ply and radial, since this model's fitments remain within radial construction.
That shifts the restoration decision toward visual presentation rather than construction conversion. A blackwall performance radial tends to suit the car's original era more naturally, while wide whitewall or redline options create a more customized or specialty look in the sizes where those sidewalls are available.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Porsche 944?
Yes, modifications can affect tire fitment on a 1989 Porsche 944 even when the tire size itself is one of the correct sizes for the model range. Aftermarket wheels, changes in wheel width, suspension lowering, altered alignment, or bodywork differences can all change the space available around the tire.
That is especially important on S2 and Turbo cars that may use different front and rear sizes or wider 16-inch rear tires. Verifying actual wheel diameter, wheel width, and clearance at steering lock and suspension travel helps confirm that the chosen tire suits the car as it sits today.
What should I inspect before driving a 1989 Porsche 944 on new tires?
Before driving a 1989 Porsche 944 on new tires, inspect the wheels for correct diameter and condition, confirm the tire is mounted in the proper front or rear position, and check inflation, valve stems, and overall installation quality. It also helps to make sure tread and sidewalls are free of shipping damage or mounting-related scuffs.
A short initial road check should confirm that the car tracks properly and that there is no rubbing during turning or over bumps. On a collector car that may sit for long periods, it is also wise to inspect suspension wear, alignment condition, and any old wheel hardware before regular road use.
How should tires on a collector 1989 Porsche 944 be maintained?
Tires on a collector 1989 Porsche 944 should be maintained with regular pressure checks, visual inspection for cracks, bulges, cuts, and uneven wear, and periodic review of overall age and condition. Low-mileage collector cars can still develop tire issues simply from time, storage conditions, and long periods of inactivity.
Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires between drives. Routine checks are especially important on a 944 with staggered or performance-oriented fitments, because catching air loss, clearance issues, or abnormal wear early helps protect both drivability and appearance.
