The 1986 Porsche 928 came from a period when Porsche grand touring cars blended high-speed capability with long-distance comfort, and the 928 stood apart with its front-engine layout and distinctly modern feel. For owners of this exact model year, tire selection is more about choosing the right interpretation of one established fitment than sorting through multiple factory sizes. The 1986 Porsche 928 uses a 225/50R16 radial on a 16-inch rim. Within that size, available choices center on blackwall performance-oriented radial options from BFGoodrich and Michelin. The real decision is balancing the car’s intended road use, wheel compatibility, and the kind of modern driving character you want from a correct-size tire.
Which Tire Size Is Right for The 1986 Porsche 928
The 1986 Porsche 928 uses one primary tire size: 225/50R16, a radial fitment for a 16-inch rim. The covered 928 S sub-model uses the same size, so the main choice is not between different fitments but between available radial tires, their series, and how each option suits the car’s wheel setup and intended use.
225/50R16 is a metric radial size in which 225 identifies the nominal section width in millimeters, 50 is the aspect ratio, R designates radial construction, and 16 is the wheel diameter in inches. On a 1986 Porsche 928, that means a modern low-profile radial format rather than a vintage bias-ply size. Available choices in this fitment include blackwall tires from BFGoodrich and Michelin across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, and Pilot Sport. Staying with this size keeps the selection focused on proper wheel diameter, compatible rim width, and the road manners expected from a grand touring Porsche.
Tire fitment is straightforward across the covered 1986 Porsche 928 sub-models. The key point is confirming the exact sub-model and wheel setup so the correct 225/50R16 radial fitment is matched to the car before comparing tire choices.

1986 Porsche 928 S
The 1986 Porsche 928 S uses the same 225/50R16 radial fitment, so the sub-model does not introduce a different primary tire size. That keeps the decision centered on selecting the right blackwall radial tire for the car’s wheels, intended driving use, and overall handling character.
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 1986 Porsche 928?
The 1986 Porsche 928 uses a 225/50R16 radial tire. That size is the primary fitment for this model year and gives the car a modern metric radial format built around a 16-inch wheel.
The practical step is confirming that the car still has the correct wheel diameter and a compatible wheel width before choosing among available tires. Many older performance cars have seen wheel changes over the years, so matching the tire size to the actual wheels on the car matters just as much as matching the year and model.
What size rim does a 1986 Porsche 928 use?
The primary tire fitment for the 1986 Porsche 928 is built around a 16-inch rim. The tire size itself, 225/50R16, also confirms that wheel diameter because the final number in the size code represents the rim size in inches.
Wheel width still needs to be checked along with diameter, especially on a car that may have aftermarket wheels or a staggered setup from a previous owner. The available 225/50R16 products shown here are intended for 16-inch wheels and call for attention to rim-width compatibility before installation.
Does the 1986 Porsche 928 S use the same tire size?
Yes. The covered 1986 Porsche 928 S uses the same 225/50R16 radial tire size as the core 1986 Porsche 928 fitment. That means tire selection stays within one main size rather than branching into separate sub-model-specific fitments.
That consistency simplifies shopping, but it does not remove the need to inspect the actual wheel and tire setup on the car. A 928 S with non-original wheels, suspension changes, or a long period of storage should still be checked carefully so the replacement tire matches the wheel diameter, wheel width, and available clearance.
Choosing the Right Tire
What should I consider when choosing a 225/50R16 tire for a 1986 Porsche 928?
Start with the correct size, which is 225/50R16, and make sure the tire is intended for a 16-inch wheel with compatible rim width. From there, the important differences are tire series, brand, construction details within the radial category, and any load-related specifications shown for the specific product.
A 1986 Porsche 928 is a grand touring performance car, so the right choice depends on how the car is actually used. A lightly driven collector car may prioritize brand preference and overall feel, while a regularly exercised car may push the decision toward comparing weight, tire series character, and wheel-width suitability more closely.
What sidewall styles are available for 1986 Porsche 928 tires?
The available 225/50R16 tires for the 1986 Porsche 928 use a blackwall sidewall style. That gives the selection a clean, modern presentation that suits the 928’s 1980s performance-touring character without adding whitewall or raised-letter appearance choices.
Since sidewall treatment is not the main differentiator here, the better comparison points are brand, tire series, and wheel-width compatibility. Owners who want the car to look right on the road should also consider the overall proportion of the tire on the wheel and whether the existing wheels preserve the stance and visual balance they want.
What brands offer tires for the 1986 Porsche 928?
Available tires in the 1986 Porsche 928’s 225/50R16 fitment include BFGoodrich and Michelin. Within those brands, the visible choices include BFGoodrich g-Force series options and the Michelin Pilot Sport, all in blackwall radial form for a 16-inch rim.
Brand choice is only one part of the decision. It helps to compare the specific tire series, the wheel-width range, and any published load or weight information tied to the product, then match those details to how the car is driven. A correct-size tire from either brand still needs to suit the wheels and condition of the individual car.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Porsche 928?
A period-style approach for a 1986 Porsche 928 starts with keeping the correct 225/50R16 size and a blackwall radial presentation. That preserves the basic visual character of the car far better than moving to a visibly different size or an incorrect wheel diameter.
From there, the decision becomes one of series and brand rather than vintage-style sidewall ornamentation. Owners aiming for a more exact restoration standard should compare the car against marque references, period photography, and model-specific documentation, especially if the car has changed hands or may no longer wear its original wheel setup.
Does correct tire fitment matter for a 1986 Porsche 928 restoration?
Yes, correct tire fitment matters because the 1986 Porsche 928’s stance, wheel-to-tire proportion, and overall road presence depend heavily on staying with the proper 225/50R16 radial format. Even a tire that physically mounts can alter the visual balance if the size or profile departs too far from the intended fitment.
Correct fitment also matters beyond appearance. Tire size affects wheel compatibility, clearance, and the way the car feels on the road, all of which are important on a front-engine Porsche built for high-speed touring. A restoration-minded owner should verify the actual wheels on the car before treating any replacement tire as visually or mechanically appropriate.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Porsche 928?
Yes. A 1986 Porsche 928 may have aftermarket wheels, suspension changes, ride-height adjustments, or brake upgrades that affect how a 225/50R16 tire sits in the car. Even when the size itself is correct, wheel width and other chassis changes can alter clearance at the fender, suspension, or steering components.
That is why the actual setup on the car should be checked before replacement tires are chosen. Looking at wheel diameter, wheel width, and available space around the tire helps avoid surprises. On an older performance car, visual fit alone is not enough; the tire should be evaluated through the full range of steering and suspension movement.
What should I inspect before driving a 1986 Porsche 928 on new tires?
Before driving a 1986 Porsche 928 on new tires, inspect the wheels for damage, confirm the tire size matches the rims, and make sure inflation is set correctly for the installed tires and vehicle setup. It also helps to check alignment condition, valve stems, and whether the car has any signs of rubbing or uneven prior tire wear.
A collector-era car should also be looked over for suspension wear, aged bushings, and any evidence that it has been sitting for long periods. New tires can only work properly if the rest of the chassis is ready for road use. A careful pre-drive inspection is especially important before highway use or a longer first outing.
How should 225/50R16 tires on a collector 1986 Porsche 928 be maintained?
225/50R16 tires on a collector 1986 Porsche 928 should be maintained with regular pressure checks, visual inspection for cracking, cuts, bulges, and uneven wear, and periodic movement of the car so the tires are not left sitting in one position for extended periods. Clean, dry storage also helps preserve low-use collector tires.
Attention to age matters just as much as tread depth on a car that is not driven often. Tires that look acceptable can still deserve closer inspection if they have spent years exposed to heat, sunlight, or long storage. Keeping the wheels aligned and the suspension in good condition also helps the tires wear evenly and stay roadworthy.
