The 1991 Porsche 944 sits at the refined end of Porsche’s front-engine transaxle era, blending balanced handling with the crisp, modern feel buyers expect from a late-production 944. That makes tire fitment especially important, because this car relies on a staggered radial setup rather than a one-size-fits-all arrangement. The 1991 Porsche 944 S2 uses 205/55R16 up front and 225/50R16 at the rear on 16-inch rims. Available choices include performance-oriented blackwall radials from BFGoodrich and Michelin, plus a wide whitewall option in the front size for a more customized presentation. The right selection starts with confirming front versus rear position, then matching tire character to the car’s intended look and road use.
Which Tire Size Is Right for The 1991 Porsche 944
The 1991 Porsche 944 uses two primary tire sizes, and the difference is tied to front and rear fitment on the S2 setup. Both are radial tires for 16-inch rims, so the first step is confirming which axle you are replacing before choosing a tire. Once that is clear, the real decision becomes comparing available brands, tire series, and sidewall treatment within the correct front or rear size.
In 205/55R16, the 205 identifies nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 16 is the rim diameter in inches. On the 1991 Porsche 944, this size is used at the front in the S2 configuration and reflects the car’s late-model metric radial fitment. Available choices include BFGoodrich, Michelin, and American Classic offerings, with blackwall options dominating and a wide whitewall version adding a more distinctive visual direction. This is the size to evaluate when replacing front tires and preserving the intended front-to-rear stagger.
In 225/50R16, the 225 is the nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. On the 1991 Porsche 944, this size is used at the rear in the S2 arrangement, giving the car its wider rear tire pairing on the same 16-inch rim diameter. BFGoodrich and Michelin both offer blackwall choices in this size across sport-oriented tire series. This is the size to confirm when replacing rear tires, especially if the car has seen wheel, suspension, or stance changes over time.
Sub-model fitment on the 1991 Porsche 944 is straightforward once front and rear position are separated correctly. The S2 uses a staggered setup, so tire choice depends on matching the correct size to the correct axle rather than treating all four corners the same.

1991 Porsche 944 S2 Front
The 1991 Porsche 944 S2 Front uses a 205/55R16 radial on a 16-inch rim. Tire selection here centers on choosing the right front-size radial while comparing available brands, series, and sidewall style to suit the car’s intended road use and appearance.
The 1991 Porsche 944 S2 Rear uses a 225/50R16 radial on a 16-inch rim. That means rear tire selection should stay focused on the wider rear size and should be checked carefully if the car has aftermarket wheels or any changes that could affect 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.

Common 1991 Porsche 944 tire questions usually come down to the staggered 16-inch fitment, front-versus-rear sizing, available radial choices, and what to inspect before putting a collector-driven 944 back on the road.
Tire Size & Fitment
What tire size fits a 1991 Porsche 944?
The 1991 Porsche 944 uses two tire sizes in the S2 configuration: 205/55R16 at the front and 225/50R16 at the rear. Both are radial sizes mounted on 16-inch rims, so this car does not use the same tire size at all four corners in that setup.
That staggered arrangement means tire selection starts with confirming whether you are replacing a front tire or a rear tire. It is also smart to verify the actual wheel setup on the car, since some 944s may have changed wheels over the years and an incorrect axle position can lead to ordering the wrong size.
What size rim does a 1991 Porsche 944 use?
The 1991 Porsche 944 uses 16-inch rims with its 205/55R16 front tire and 225/50R16 rear tire setup. Even though the tire widths and aspect ratios differ front to rear, both sizes are built around the same 16-inch rim diameter.
Rim diameter is only one part of the fitment picture, so wheel width still matters when comparing tire choices. Front products in 205/55R16 commonly suit 5.5 to 7.5-inch rim widths, while rear 225/50R16 choices commonly suit 6.0 to 8.0-inch widths, making wheel verification worthwhile before replacement.
Why does the 1991 Porsche 944 have more than one tire size?
The 1991 Porsche 944 S2 uses a staggered setup, with 205/55R16 tires at the front and 225/50R16 tires at the rear. That means the car uses one size for steering axle duty and a wider size at the rear, rather than a uniform four-tire arrangement.
For the buyer, that makes axle position the first fitment decision. Mixing up the front and rear sizes can create problems with mounting, appearance, and overall setup, so it helps to inspect the wheels already on the car and confirm that the current layout still matches the intended 944 S2 front-and-rear pairing.
Choosing the Right Tire
What should I consider when choosing a 1991 Porsche 944 tire?
Start by matching the correct size to the correct axle: 205/55R16 for the front and 225/50R16 for the rear on the 1991 Porsche 944 S2. From there, compare radial construction details such as rim-width compatibility, load specification where stated, tire series, and the overall character of the tire.
A performance-focused blackwall radial may suit a road-driven 944 differently than a tire chosen mainly for appearance. It also helps to check whether the car still has its original wheel configuration, because wheel-width changes, suspension alterations, or a custom stance can affect which available tire is the most sensible match.
What sidewall styles are available for 1991 Porsche 944 tires?
Most available 1991 Porsche 944 tire choices use a blackwall sidewall, which matches the performance-oriented look expected from a late-model Porsche fitment. In the 205/55R16 front size, there is also a wide whitewall radial option for owners building a more customized visual style.
Sidewall style does not change the need to stay with the correct front or rear size, but it can change the overall presentation of the car considerably. A blackwall keeps the appearance closer to a modern sport coupe theme, while a wide whitewall pushes the front tire toward a much more personalized look.
What brands offer tires for the 1991 Porsche 944?
BFGoodrich and Michelin both offer tires for the 1991 Porsche 944 in the applicable 16-inch sizes, and American Classic appears in the 205/55R16 front size. The available tire series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Michelin SX MXX3 N2, Michelin Pilot Sport, and American Classic Radial.
That brand mix gives the buyer a useful range of choices without changing the car’s required front-versus-rear sizing logic. The next step is comparing the tire series, sidewall style, and wheel-width compatibility for the exact axle position being replaced, rather than choosing on brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Porsche 944?
A period-style 1991 Porsche 944 usually starts with keeping the correct staggered 16-inch radial sizing in place, using 205/55R16 at the front and 225/50R16 at the rear for the S2 setup. Within those sizes, blackwall radials from BFGoodrich or Michelin maintain the most natural late-model sports-car presentation.
Appearance goals should still be balanced against how the car will be used. A restoration-oriented owner may focus on visual authenticity and tire series character, while a regularly driven car may put more weight on current radial design and wheel compatibility, especially if the wheels or suspension no longer match original-type dimensions.
How does tire construction affect the appearance of a restored 1991 Porsche 944?
On a 1991 Porsche 944, radial construction is already part of the vehicle’s proper late-model fitment story, so staying with radial tires preserves the overall look and stance expected from a 16-inch 944 setup. The bigger appearance difference comes from tire profile, sidewall treatment, and the relationship between front and rear sizing.
For most restoration-minded cars, blackwall radials keep the visual character closest to a factory-era sports coupe theme. A wide whitewall front tire creates a much more custom look, so owners pursuing strict originality should compare that choice against marque-specific historical references before making appearance-driven changes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Porsche 944?
Yes, modifications can affect tire fitment on a 1991 Porsche 944 even when the nominal tire size remains 205/55R16 in front and 225/50R16 in the rear. Aftermarket wheels, changes in wheel width, altered offset, lowered suspension, or body modifications can all influence whether a tire clears properly.
That makes it wise to inspect the car rather than assume every 944 still matches its original-style configuration. Measuring the installed wheels and checking steering, fender, and suspension clearance before mounting new tires can prevent problems, especially on a car that has changed hands several times or has been modified for style or performance.
What should I inspect before driving a 1991 Porsche 944 on new tires?
Before driving a 1991 Porsche 944 on new tires, check that the correct front and rear sizes are mounted in the correct positions, that tire pressures are set properly for the intended use, and that there is no visible interference at the fenders, steering components, or suspension. Lug torque and valve condition also deserve attention.
A collector-driven 944 should also have its wheels inspected for age-related issues, curb damage, and previous repairs before regular road use. Once the tires are installed, a short initial drive followed by a second visual check can help catch rubbing, uneven seating, or air loss before the car is taken on a longer run.
How should tires on a collector 1991 Porsche 944 be maintained?
Tires on a collector 1991 Porsche 944 should be checked regularly for pressure loss, tread wear, sidewall cracking, cuts, bulges, and any signs of age-related deterioration. Because many 944s are driven intermittently, visual condition matters just as much as tread depth, especially when the car spends long periods parked.
Storage habits also matter. Keeping the car away from prolonged sunlight, excess heat, standing moisture, and ozone sources helps protect the tires between drives, and moving the car occasionally can reduce flat-spotting during longer storage periods. A careful inspection before each road season is a smart habit on any low-use Porsche.
