Porsche 968 Tires
Porsche 968 was produced from 1992 through 1995 as the final evolution of Porsche’s front-engined transaxle sports-car line, blending balanced road manners with the sharper performance expected of a modern grand touring coupe and cabriolet of the period. That matters for tire selection because the Porsche 968 sits in a transition era where factory wheel and tire packages could vary within the same model years. Across the Porsche 968 range here, both 16-inch and 17-inch rim diameters appear in every year, so size choice is not year-specific alone. The first step is to confirm whether the car is wearing 16-inch or 17-inch wheels before narrowing the correct tire size.
Porsche 968 Tire Size Guide
Porsche 968 production used 4 distinct tire sizes from 1992 through 1995, and the critical fitment fact is that both 16-inch and 17-inch rim diameters were used throughout the run rather than in a simple year-to-year change. All four sizes are metric radial sizes, with section width in millimeters, aspect ratio as a percentage of that width, radial construction, and the final number showing the wheel diameter in inches. Because every year lists more than one size, the wheel diameter and specific front or rear fitment need to be confirmed on the actual car before choosing tires.
205/55R16 applies to Porsche 968 models across 1992 through 1995 on 16-inch wheels. The code indicates a 205 mm section width, a 55-series aspect ratio, radial construction, and a 16-inch rim diameter. Choose this size only if the car is equipped for this 16-inch fitment, and available products include blackwall and wide whitewall radial options.
225/50R16 applies to Porsche 968 models across 1992 through 1995 on 16-inch wheels. The code indicates a 225 mm section width, a 50-series aspect ratio, radial construction, and a 16-inch rim diameter. Choose this size when the car’s 16-inch wheel package calls for the wider 225-section fitment rather than the narrower 205-section option.
225/45R17 applies to Porsche 968 models across 1992 through 1995 on 17-inch wheels. The code indicates a 225 mm section width, a 45-series aspect ratio, radial construction, and a 17-inch rim diameter. Choose this size only for cars fitted with the corresponding 17-inch wheel package, and sidewall styles in this size include blackwall, RWL, and redline.
255/40R17 applies to Porsche 968 models across 1992 through 1995 on 17-inch wheels. The code indicates a 255 mm section width, a 40-series aspect ratio, radial construction, and a 17-inch rim diameter. Choose this size only when the car’s wheel package requires the wider 17-inch fitment, and verify wheel width as well as tire size before final selection.
Every 1992 through 1995 Porsche 968 year lists four sizes, so identify the car’s specific wheel setup rather than relying on the year alone; the split here is by 16-inch versus 17-inch rim diameter.
Porsche 968 Tires by Year
Porsche 968 year listings show which tire sizes appear for each model year and help narrow the correct fitment by wheel package. In 1992, 1993, 1994, and 1995, more than two sizes are listed, so the key distinction is the split between 16-inch and 17-inch wheels. Check the actual wheel diameter on the car first, then use the year listing to match the available size choices.

Frequently Asked Questions
The FAQ below addresses the wheel-package split that runs through every Porsche 968 model year, explains how to decode the metric radial sizes, and covers practical questions about available brands, sidewall styles, and long-term collector tire care.
Size Basics & Fitment
Porsche 968 fitments in this range are 205/55R16, 225/50R16, 225/45R17, and 255/40R17. All four sizes appear for 1992, 1993, 1994, and 1995 models. The 205/55R16 and 225/50R16 sizes are for 16-inch rims, while 225/45R17 and 255/40R17 are for 17-inch rims. All available products in these sizes are radial construction.
That means the correct choice depends on the wheel package fitted to the specific Porsche 968, not simply the model year. Start by reading the tire sidewall already on the car and measuring or confirming the wheel diameter. If the car has staggered sizing, verify both front and rear positions rather than assuming all four tires use the same size.
A 1992 Porsche 968 has four tire sizes listed because more than one wheel and tire configuration appears within the same model year. The split is by rim diameter, with 16-inch sizes and 17-inch sizes both used in 1992. The listed sizes are 205/55R16 and 225/50R16 for 16-inch wheels, plus 225/45R17 and 255/40R17 for 17-inch wheels.
That kind of overlap is typical of performance cars offered with different wheel packages rather than a simple one-size-fits-all setup. The practical step is to verify the wheel diameter and check whether the car uses the same size at all four corners or a wider rear fitment. Once that is established, the year listing becomes much easier to use accurately.
Porsche 968 uses both 16-inch and 17-inch rim diameters in this fitment range. The 16-inch group includes 205/55R16 and 225/50R16, while the 17-inch group includes 225/45R17 and 255/40R17. Every model year from 1992 through 1995 shows both rim diameters, so there is no single year break where one wheel size replaced the other.
That makes wheel diameter the first fitment check on any Porsche 968. Read the tire size on the car now, inspect the wheel itself, and confirm that the replacement size matches both the rim diameter and the intended wheel position. A correct section width and aspect ratio still matter, but the wheel diameter has to be right before anything else.
Buying the Right Tire
A 1994 Porsche 968 can use 205/55R16, 225/50R16, 225/45R17, or 255/40R17 depending on the wheel package and tire position. The first distinction is 16-inch versus 17-inch wheels, and the second is whether the car uses matching sizes front to rear or a wider rear fitment. Because all four sizes appear in the same year, the model year alone is not enough to choose correctly.
Check the current tire sidewalls, then confirm the wheel diameter and width at each axle. If the car has been changed from its earlier setup, use the actual wheel dimensions now on the car rather than assumptions tied to the VIN plate or registration year. For a collector Porsche, it is also wise to compare against service records or marque references if originality matters.
Porsche 968 tires in this range are available with several sidewall styles depending on size. Blackwall is the most common style across all four sizes. In 225/45R17, RWL and redline versions are also available, and in 205/55R16 there is a wide whitewall radial option. Those sidewall treatments are product-specific rather than universal across the entire size range.
For a period-correct late classic sports-car look, blackwall is usually the most natural visual match. The RWL, redline, and whitewall options are more of a styling choice and should be selected carefully with the overall presentation of the Porsche 968 in mind. Make sure the desired sidewall style is offered in the exact size required for the wheel on the car.
Porsche 968 tires in these sizes are available from BFGoodrich, Michelin, American Classic, Nitto, Pro-Trac, and Vredestein. BFGoodrich appears across all four listed sizes, while the other brands are size-specific within the range. The available series include performance-oriented radial choices as well as a few style-driven alternatives in select sizes.
Brand selection should follow the fitment first and the intended use second. A Porsche 968 driven regularly may call for a different tread and sidewall preference than one built primarily for show presentation. Once the correct size and wheel diameter are confirmed, compare the available brands within that size for appearance, period feel, and performance emphasis.
Porsche 968 tires here span several radial series, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Michelin SX MXX3 N2, Michelin Pilot Sport, American Classic Radial, Nitto NT555 G2, Street Pro III, and Vredestein Sprint Plus. The main differences are tread design, sidewall styling, and whether the tire is positioned as an all-season, performance street, or appearance-focused radial. Construction remains radial throughout this range.
That means the real choice is less about bias-ply versus radial and more about how you want the Porsche 968 to look and behave. A blackwall performance radial suits a modern driving character, while options like RWL, redline, or wide whitewall shift the visual tone considerably. Start with the exact required size, then narrow the series by use case and presentation.
Maintenance & Longevity
A Porsche 968 stored on fitted tires should be kept in a cool, dry, dark space away from direct sunlight, ozone sources, and extreme temperature swings. Tires last better when they are clean, properly inflated, and not left supporting the full vehicle weight in one position for long periods. A car cover helps the body, but the tire environment matters just as much.
For longer storage, move the Porsche 968 periodically to change the contact patch or use appropriate supports as part of a broader preservation plan. Avoid parking on damp soil or surfaces that trap moisture. Before returning the car to regular use, recheck inflation, inspect for flat spotting or cracking, and make sure all four tires still match the intended wheel positions.
Tires on a Porsche 968 should be visually inspected before each drive and given a more thorough inspection at regular service intervals. Look for cracking, sidewall damage, punctures, uneven wear, and signs of aging around the bead and tread blocks. On a collector car, long periods of inactivity can age tires even when tread depth still appears strong.
A practical routine is to check pressures and condition monthly during storage, then inspect again any time the car is taken out after sitting. If the Porsche 968 has staggered sizing or multiple wheel sets, label and track each set carefully so wear patterns do not confuse future fitment decisions. Any vibration or steering change should trigger a closer inspection immediately.
Tires on a Porsche 968 should be replaced when age, cracking, hardening, impact damage, or structural concerns appear, even if the tread still looks usable. Collector cars often accumulate time faster than miles, so visual age and rubber condition matter more than tread depth alone. Any tire showing sidewall separation, exposed cords, or persistent air loss is beyond normal service use.
An older sports car can mask tire deterioration because it is driven infrequently, which makes date-code review and periodic professional inspection important. If the car has sat for years, treat the tires as suspect until proven otherwise. Replacing aged tires in matching correct sizes is usually the safest way to preserve both the driving feel and the wheel-package balance of the Porsche 968.
Safety & Road Use
These Porsche 968 tires are modern radial designs in the listed sizes, which makes them suitable for normal road use when they are correctly matched to the car’s wheel diameter, load needs, and overall condition. Safety depends on proper fitment, sound wheels, correct inflation, and the age and condition of the individual tire. A performance car like the Porsche 968 is especially sensitive to tire mismatches front to rear.
Before regular road use, confirm that the car has the correct size at each wheel position and that no old or damaged tire remains in service. A freshly restored or newly acquired Porsche 968 deserves a full chassis and brake inspection alongside tire evaluation. Good tires help, but safe road use comes from the whole package working together.
Before driving a Porsche 968, check tire pressure, sidewall condition, tread condition, and the exact size fitted at each corner. Also confirm that the tires match the wheel diameter, since both 16-inch and 17-inch fitments appear across all model years in this range. Uneven wear, bulges, or rubbing marks deserve attention before the car is driven at speed.
A short pre-drive walkaround is especially worthwhile on collector cars that sit between outings. If the Porsche 968 has recently changed wheels, verify wheel width and tire clearance as well as the size code itself. Taking a few minutes to inspect the tires can prevent avoidable handling issues and helps preserve the balanced character these transaxle Porsches are known for.
A Porsche 968 should only be driven at speeds appropriate to the actual condition, age, and type of tires fitted to the car, not simply the car’s performance potential. Modern radial replacements in sound condition can support normal road driving within their service ratings, while aged or neglected tires should not be trusted for spirited use. Tire age, inflation, and condition are just as important as the size itself.
The sensible approach is to build speed gradually after confirming that the tires are fresh, balanced, and free of age-related damage. If the Porsche 968 has an older set of tires with little recent use, treat the first drives as evaluation miles rather than performance driving. Stable handling, no vibration, and consistent temperatures are good signs before extending road speed further.
