The 1995 Porsche 928 sits at the end of Porsche’s front-engine V8 grand touring era, combining high-speed road manners with the wider, more purposeful stance of the late GTS models. Tire fitment on this car is tied directly to that staggered setup, using 225/45R17 in front and 255/40R17 in the rear, both in radial construction on 17-inch wheels. That means the real choice is not between vintage sizing systems, but between front and rear placement, tire series, and sidewall presentation within the correct modern metric sizes. For road use, appearance, and handling balance, keeping the staggered fitment and confirming the actual wheel setup matters.
Which Tire Size Is Right for The 1995 Porsche 928
The 1995 Porsche 928 uses two primary tire sizes, both on 17-inch rims, and the difference is positional rather than optional. The front uses 225/45R17 while the rear uses 255/40R17, so the first step is confirming whether you are replacing the front tires, the rear tires, or a full staggered set. Once that is established, the decision shifts to brand, tire series, sidewall style, and the rim-width specifications that match the wheel on the car.
225/45R17 is a metric radial size in which 225 identifies the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 1995 Porsche 928, this size serves the front position and supports the car’s staggered late-model GTS fitment. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, raised white letter, and Redline sidewall treatments depending on the tire series. This is the size to evaluate when preserving proper front-end fitment, steering response, and appearance on the correct 17-inch wheel.
255/40R17 is a metric radial size where 255 identifies the nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 17 marks the wheel diameter in inches. On the 1995 Porsche 928, this is the rear tire size and it works with the wider rear wheel and stance of the staggered setup. Product choices in this size include BFGoodrich, Nitto, and Vredestein, with Blackwall styling across the available series. This is the size to compare when replacing the rear tires and maintaining the intended front-to-rear fitment relationship.
Sub-model fitment on the 1995 Porsche 928 is straightforward, but it is split by axle position rather than by trim variation. Checking whether the tire belongs on the front or rear matters because the GTS uses different sizes at each end of the car.

1995 Porsche 928 GTS Front
The 1995 Porsche 928 GTS Front uses a 225/45R17 radial tire on a 17-inch wheel. That makes front-tire selection a matter of choosing the right series, brand, and sidewall style while keeping the correct size for the front axle.
The 1995 Porsche 928 GTS Rear uses a 255/40R17 radial tire on a 17-inch wheel. Rear replacement should focus on the proper staggered size, along with wheel-width compatibility and a tire series that suits how the car is driven and presented.
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 1995 Porsche 928?
The 1995 Porsche 928 uses a staggered radial setup with 225/45R17 in the front and 255/40R17 in the rear. Both sizes are designed for 17-inch wheels, and they are not interchangeable front to rear as a normal replacement practice because each position uses its own dedicated size.
That means tire selection starts with identifying axle position, not just model year. A full replacement should preserve the front and rear size relationship unless the car has been modified, and a single-tire purchase should always be matched to the correct wheel location, wheel width, and overall setup already on the car.
What size rim does a 1995 Porsche 928 use?
The 1995 Porsche 928 uses 17-inch rims with both of its primary tire sizes. The front 225/45R17 and rear 255/40R17 are both built around the same wheel diameter, even though the rear tire is wider and uses a different aspect ratio.
Wheel diameter is only part of the fitment picture, especially on a staggered car. Width also matters, so it is worth confirming the actual front and rear wheel widths before ordering replacements, particularly if the 928 has aftermarket wheels or if the current wheel setup differs from the original GTS-style arrangement.
Why does the 1995 Porsche 928 have more than one tire size?
The 1995 Porsche 928 has more than one tire size because it uses a staggered setup, with 225/45R17 in front and 255/40R17 in the rear. The narrower front and wider rear arrangement is part of how this late-model 928 is fitted, rather than an either-or size choice for the same wheel position.
For replacement, that means the key decision is not choosing between two acceptable all-around sizes. The important step is matching each tire to its correct axle position and confirming that the wheels on the car still reflect the intended staggered arrangement, especially if ownership history includes wheel changes or suspension modifications.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 or 255/40R17 tire for a 1995 Porsche 928?
Start with the correct axle position, since the 1995 Porsche 928 uses 225/45R17 in front and 255/40R17 in the rear. From there, compare radial construction details such as tire series, brand, sidewall style, rim-width suitability, and any available load figures that apply to the exact tire being considered.
A good choice depends on how the car is actually used and presented. Some owners want a straightforward Blackwall performance look, while others may prefer a more distinctive sidewall treatment on the front size where those options exist. Matching the tire to the wheel and preserving the staggered setup are more important than choosing by appearance alone.
What sidewall styles are available for 1995 Porsche 928 tires?
Sidewall choices for the 1995 Porsche 928 include Blackwall across both primary sizes, with additional raised white letter and Redline offerings in the 225/45R17 front size. The 255/40R17 rear options shown here are Blackwall, so sidewall variety is broader at the front than at the rear.
That matters if appearance is part of the decision, because the car’s staggered setup may limit matching sidewall treatments across all four corners. Owners aiming for a coordinated look should compare front and rear availability together rather than selecting one tire at a time, especially when mixing brands or series is under consideration.
What brands offer tires for the 1995 Porsche 928?
Tires for the 1995 Porsche 928 are available from BFGoodrich, Nitto, Pro-Trac, and Vredestein across the two primary 17-inch sizes. BFGoodrich appears in both front and rear sizes, Nitto also covers both positions, Pro-Trac appears in the front size, and Vredestein appears in the rear size.
Brand choice should be weighed alongside the exact size needed, the tire series offered in that size, and the sidewall presentation you want on the car. A staggered setup often narrows the overlap between front and rear choices, so it is helpful to compare complete front-and-rear combinations instead of judging one size in isolation.
Restoration & Appearance
Which tire should I choose for a period-style 1995 Porsche 928?
A period-style approach to a 1995 Porsche 928 starts with retaining the proper staggered sizes: 225/45R17 in front and 255/40R17 in the rear. Since this is already a modern radial fitment, the appearance decision usually comes down to tire series and sidewall treatment rather than choosing between vintage bias-ply and radial constructions.
For a restrained late-1990s presentation, Blackwall tires keep the look closest to how many grand touring performance cars were typically seen on the road. Owners pursuing exact originality should still compare tire branding and appearance against marque references, period photos, or other Porsche-specific documentation before making a final cosmetic decision.
How does tire construction affect the appearance of a restored 1995 Porsche 928?
Tire construction changes the appearance of a restored 1995 Porsche 928 less dramatically than it would on an earlier collector car, because this model already uses modern radial sizes. The more visible differences here are usually sidewall styling, tread presentation, and how well the chosen front and rear tires maintain the car’s intended staggered stance.
That makes proportion and consistency especially important. A Blackwall setup creates a clean late-model grand touring look, while raised white letter or Redline styling on the front size introduces a more customized visual statement. The best result usually comes from treating the front and rear tires as one coordinated set rather than separate appearance decisions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1995 Porsche 928?
Yes, modifications can affect tire fitment on a 1995 Porsche 928 even when the nominal tire sizes remain 225/45R17 in front and 255/40R17 in the rear. Aftermarket wheels, altered wheel widths, suspension changes, ride-height adjustments, and body or alignment changes can all influence how those sizes sit and clear the car.
That is why the actual wheel setup should be checked before replacement, especially on a car with unknown history. Confirm the wheel diameter, measure wheel width, and inspect for clearance at the fender, suspension, and steering range so the selected tire matches the 928’s current configuration rather than assumptions about a stock setup.
What should I inspect before driving a 1995 Porsche 928 on new tires?
Before driving a 1995 Porsche 928 on new tires, inspect wheel condition, confirm the front and rear sizes are installed in the correct positions, and verify inflation pressure for the tires being used. It is also wise to look over the valve stems, check that the beads are seated properly, and make sure there is no visible interference.
A short initial road test should include attention to vibration, pulling, unusual rubbing, and steering feel. Since the car uses a staggered arrangement, front-to-rear placement matters, and any recent suspension work or wheel changes deserve a second look before a longer drive or higher-speed use.
How should 225/45R17 and 255/40R17 tires on a collector 1995 Porsche 928 be maintained?
Collector-car tire maintenance for a 1995 Porsche 928 starts with regular pressure checks, visual inspection, and keeping the staggered front and rear sizes in their proper positions. Even on a low-mileage car, tires should be examined for cracking, cuts, bulges, uneven wear, and slow air loss rather than judged by tread depth alone.
Storage conditions also matter because a seldom-driven grand touring car can age tires without putting many miles on them. Keeping the 928 away from prolonged heat, direct sunlight, moisture, and ozone sources helps preserve the tires, and periodic inspections before road use are especially important after extended storage.
