The 1984 Porsche 928 sits firmly in Porsche’s front-engine grand touring era, blending V8 power, high-speed stability, and a distinctly modern-for-its-time approach to long-distance performance. Buyers looking at one today are often balancing originality, drivability, and the realities of maintaining a sophisticated 1980s GT. This 1984 Porsche 928 uses a 225/50R16 radial tire, so the fitment conversation centers less on vintage bias-ply choices and more on selecting the right modern radial in the correct size. Available options include Blackwall tires from BFGoodrich and Michelin across several performance-oriented series. The important step is matching the tire to the car’s wheel setup, road use, and overall presentation.
Which Tire Size Is Right for The 1984 Porsche 928
The 1984 Porsche 928 uses one primary tire size: 225/50R16, a radial fitment for a 16-inch rim. The 928 S sub-model uses that same size, so the main decision is not which size fits, but which 225/50R16 tire best suits the car’s intended use, wheel width, and preferred driving character within the available modern radial choices.
In 225/50R16, the 225 is the nominal section width in millimeters, the 50 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. For the 1984 Porsche 928, this is a modern radial performance fitment rather than an older bias-ply sizing system, which makes size accuracy and wheel compatibility especially important. Available choices in this size include BFGoodrich and Michelin Blackwall tires in g-Force Sport Comp 2, g-Force Comp 2 AS, and Pilot Sport series. That gives owners room to choose around road use, brand preference, and the actual wheel setup on the car.
Sub-model fitment is straightforward here because the covered 1984 Porsche 928 configuration uses the same primary tire size across the applicable sub-model. Checking the exact sub-model still matters because it confirms that tire selection can stay focused on product choice, wheel compatibility, and intended driving use rather than a different size.

1984 Porsche 928 S
The 1984 Porsche 928 S uses the same 225/50R16 radial tire size as the core fitment. That keeps the selection process centered on choosing among the available modern radial options and confirming that the car still carries the proper 16-inch wheel setup.
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 1984 Porsche 928?
The 1984 Porsche 928 uses a 225/50R16 radial tire. That size is the primary fitment for this application and places the car on a 16-inch wheel, using a modern metric radial format rather than an older numeric or alphanumeric vintage size system.
The practical decision is choosing the right tire within that size, not sorting through multiple primary fitments. It is still worth confirming that the car retains its correct wheel diameter and that no previous owner changed the wheel package, because a modified 928 can require a different approach than a car still running the intended 16-inch setup.
What size rim does a 1984 Porsche 928 use?
The primary tire fitment for the 1984 Porsche 928 is built around a 16-inch rim. The 225/50R16 size itself confirms that wheel diameter, and the available tires in this fitment are also built for 16-inch wheels.
Wheel diameter is only part of the picture, so rim width should also be checked before choosing among available tires. The product range in this size supports 6.0- to 8.0-inch rim widths, which makes it important to verify the actual wheels on the car rather than assuming every 16-inch wheel will suit the same tire equally well.
Does the 1984 Porsche 928 S use the same tire size?
Yes. The 1984 Porsche 928 S uses the same 225/50R16 radial tire size as the core 1984 Porsche 928 fitment covered here. That keeps sub-model fitment simple and avoids the need to sort between multiple primary sizes for this application.
That shared fitment means the real comparison happens within the available 225/50R16 product choices, such as tire series and brand. A buyer should still confirm the actual wheel setup on the specific car, especially on a vehicle that may have seen aftermarket wheel changes or suspension work during its life.
Choosing the Right Tire
What should I consider when choosing a 225/50R16 tire for a 1984 Porsche 928?
Start with the correct size, 225/50R16, and make sure the tire matches the car’s 16-inch wheel setup. From there, the main considerations are radial tire series, brand, rim-width compatibility, and whether the car is used more for touring, occasional collector driving, or regular road miles.
This fitment includes Blackwall radial choices from BFGoodrich and Michelin, so the decision is about product character rather than sidewall style changes. Wheel width should be checked carefully, since the available options share a 6.0- to 8.0-inch rim-width range and the actual wheels on the car can influence which tire makes the most sense.
What brands offer tires for the 1984 Porsche 928?
BFGoodrich and Michelin both offer tires in the 225/50R16 size for the 1984 Porsche 928. Within that fitment, BFGoodrich appears in g-Force Sport Comp 2 and g-Force Comp 2 AS form, while Michelin is available in the Pilot Sport series.
Brand choice should be considered alongside the specific tire series, wheel compatibility, and how the car is driven. Rather than treating the name on the sidewall as the whole decision, compare the tire’s overall fitment details and intended use so the selection supports the 928’s road manners and the actual configuration of the car.
What tire series are available for the 1984 Porsche 928?
The 1984 Porsche 928 has 225/50R16 tire options in BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, and Michelin Pilot Sport series. All are radial Blackwall tires built around the same 16-inch fitment.
Series names matter because they help distinguish the character of the available products even when the size stays the same. A careful buyer should compare the exact tire within the correct size, then confirm wheel width and the car’s intended use so the chosen series matches the way the 928 will actually be driven and presented.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Porsche 928?
A period-style approach for a 1984 Porsche 928 still starts with the correct 225/50R16 fitment. Since this application is already a modern radial format, the restoration-oriented decision usually centers on staying with the proper size and selecting a tire whose overall look and character suit a well-kept 1980s grand touring Porsche.
Blackwall presentation is part of that look, but appearance should be balanced with wheel compatibility and road use. Buyers pursuing strict originality should compare the car’s current setup with marque-specific historical references and ownership documentation, while others may simply want a tire that keeps the correct stance and a clean, era-appropriate visual feel.
How does tire construction affect the appearance of a restored 1984 Porsche 928?
On a restored 1984 Porsche 928, tire construction affects appearance less through bias-ply-versus-radial contrast and more through keeping the correct modern radial size and profile. The primary fitment here is already a radial 225/50R16, so the visual result depends largely on preserving the proper proportions and a clean Blackwall presentation.
A tire that departs from the intended size can alter the car’s stance and dilute the sharp, contemporary look that defines a 928 of this era. Restoration-minded owners should verify wheel diameter and width first, then choose a tire that supports the car’s visual balance rather than treating any 16-inch performance tire as automatically suitable.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Porsche 928?
Yes. Even though the standard fitment is 225/50R16, changes to wheels, suspension height, or body clearance can affect what actually works on a specific 1984 Porsche 928. A car that no longer carries its intended 16-inch wheel setup may need closer evaluation before any tire is chosen.
Aftermarket wheels can change width and offset, while suspension alterations can influence clearance during steering and compression. That is why the tire size should be matched to the car as it sits today, with attention paid to wheel dimensions and available space, rather than assuming every modified 928 will behave like an unaltered example.
What should I inspect before driving a 1984 Porsche 928 on new tires?
Before putting a 1984 Porsche 928 back on the road with new tires, inspect the wheels for damage, confirm the wheel size, and make sure the tires are mounted in the correct 225/50R16 fitment. It also helps to look over alignment condition, valve stems, and general suspension health.
Tires alone cannot correct problems caused by worn steering or suspension components, and those issues can affect how the car feels immediately after installation. A careful pre-drive check should also include tire pressure, visible clearance around the fenders and suspension, and a short initial road test to catch vibration, rubbing, or unusual behavior early.
How should 225/50R16 tires on a collector 1984 Porsche 928 be maintained?
Collector-driven 225/50R16 tires on a 1984 Porsche 928 should be maintained with regular pressure checks, routine visual inspections, and attention to age and condition even if tread wear looks minimal. Low-mileage collector cars can carry tires that appear usable at a glance but still deserve close inspection before serious road use.
Watch for sidewall cracking, bulges, cuts, uneven wear, or slow air loss, and keep the car stored away from prolonged heat, sunlight, and ozone sources when possible. The 928’s tires should also be checked before longer drives, since a grand touring car that spends long periods parked may reveal issues only when it returns to steady highway use.
