The 1988 Oldsmobile Cutlass Supreme sits squarely in the late front-drive personal coupe era, when Oldsmobile blended traditional Cutlass name recognition with more modern chassis and styling themes. Buyers today often approach one as either a preserved original, a mild restoration, or a driver that still needs to look right for the period. Tire fitment for the 1988 Oldsmobile Cutlass Supreme is entirely radial, but it is not one-size-fits-all: 14-inch applications use 195/75R14 or 205/70R14, while the Indy 500 Pace Car and International use 215/65R15. That opens up meaningful choices in whitewall, redline, raised white letter, blackwall, and touring-versus-performance-style presentation.
Which Tire Size Is Right for The 1988 Oldsmobile Cutlass Supreme
Three tire sizes apply to the 1988 Oldsmobile Cutlass Supreme, and the first step is confirming the exact sub-model and wheel diameter. Most versions use one of two 14-inch radial sizes, while the Indy 500 Pace Car and International move to a 15-inch radial. Once that is established, the real choice becomes sidewall style, brand, and whether the car is being kept in a more formal restoration-oriented look or a sportier late-1980s presentation.
Fit(s): Base, Classic (FWD), Classic Brougham, and SL
Construction: Radial|Rim: 14 in
195/75R14 is a metric radial size in which 195 identifies nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 14 is the wheel diameter in inches. On the 1988 Oldsmobile Cutlass Supreme, this size suits 14-inch-wheel applications and carries a traditional passenger-car profile that fits the period well. Available choices include Coker Classic, Tornel, Maxxis, and Travelstar, with wide whitewall and narrow whitewall options depending on the look you want. It is a strong fitment to evaluate when maintaining a softer, more formal Cutlass Supreme appearance on the correct 14-inch wheel.

205/70R14 is also a metric radial, with a 205-millimeter nominal width, a 70-series profile, radial construction, and a 14-inch rim diameter. Within the 1988 Oldsmobile Cutlass Supreme range, it is another 14-inch fitment and gives a slightly broader, lower-profile look than 195/75R14. Product choices include whitewall, redline, dual redline, raised white letter, and blackwall styles from Maxxis, BFGoodrich, and Michelin across several series. This size is worth considering when the car already has the proper 14-inch wheel setup and the owner wants a sportier visual stance without moving to a 15-inch package.
215/65R15 is a metric radial size that uses a 215-millimeter nominal section width, a 65-series aspect ratio, and a 15-inch wheel diameter. For the 1988 Oldsmobile Cutlass Supreme, this size belongs to the 15-inch applications used on the Indy 500 Pace Car and International. Available tires include Goodyear, Cooper, and BFGoodrich offerings with OWL, raised white letter, redline, and wide whitewall presentations across performance-leaning and restoration-oriented radial lines. It should be evaluated only after confirming the car is one of the 15-inch sub-models and still retains compatible wheels and clearances.
Sub-model fitment matters on the 1988 Oldsmobile Cutlass Supreme because most versions stay with 14-inch radial sizes, while two specialty trims use a 15-inch fitment. Identifying the exact sub-model prevents mixing 14-inch and 15-inch tire selections and helps narrow the right appearance and product style.

1988 Oldsmobile Cutlass Supreme Base
The 1988 Oldsmobile Cutlass Supreme Base uses one of the 14-inch radial fitments rather than the 15-inch package found on certain specialty versions. That means the focus is choosing the right 14-inch size already on the car and then selecting between whitewall, redline, raised white letter, or blackwall styling as appropriate.
The 1988 Oldsmobile Cutlass Supreme Classic (FWD) stays within the 14-inch radial tire group shared by several mainstream Cutlass Supreme variants. Tire selection comes down to confirming which 14-inch size and wheel setup the car has, then matching the sidewall style and tire series to either a formal or more athletic late-1980s look.
The 1988 Oldsmobile Cutlass Supreme Classic Brougham also uses the 14-inch radial fitment family rather than the 15-inch sporty package. That generally points buyers toward period-style whitewall or other 14-inch radial choices, with wheel diameter and the exact size on the car worth confirming before ordering.
The 1988 Oldsmobile Cutlass Supreme Indy 500 Pace Car uses the 215/65R15 radial size on a 15-inch wheel. Tire choice here centers on maintaining the correct 15-inch format and deciding whether the car calls for a sportier raised white letter or OWL look, or a more restrained radial presentation.
The 1988 Oldsmobile Cutlass Supreme International shares the 215/65R15 radial fitment used on the 15-inch-wheel applications. That makes wheel confirmation especially important, after which the buyer can compare performance-flavored sidewalls like RWL or OWL against redline and whitewall alternatives.
The 1988 Oldsmobile Cutlass Supreme SL remains in the 14-inch radial size group rather than the 15-inch fitment used by the Indy 500 Pace Car and International. Choosing tires for an SL starts with confirming which 14-inch size is on the car and then narrowing the sidewall treatment that best suits its intended look.
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.

These FAQs focus on the actual tire decisions for a 1988 Oldsmobile Cutlass Supreme, including which size belongs on which sub-model, how the 14-inch and 15-inch fitments differ, and how to choose the right radial style for restoration or road use.
Tire Size & Fitment
What tire size fits a 1988 Oldsmobile Cutlass Supreme?
The 1988 Oldsmobile Cutlass Supreme uses three radial tire sizes: 195/75R14, 205/70R14, and 215/65R15. Base, Classic (FWD), Classic Brougham, and SL models use the 14-inch sizes, while the Indy 500 Pace Car and International use 215/65R15 on a 15-inch wheel.
That makes sub-model and wheel confirmation the first step before choosing a tire. A Cutlass Supreme that has been changed over to different wheels over the years may no longer match its original fitment group, so checking the current wheel diameter and the size already mounted helps prevent ordering the wrong tire.
What size rim does a 1988 Oldsmobile Cutlass Supreme use?
A 1988 Oldsmobile Cutlass Supreme uses either a 14-inch or 15-inch rim, depending on the sub-model and tire size. The 195/75R14 and 205/70R14 fitments use 14-inch rims, while the 215/65R15 fitment uses a 15-inch rim.
Because this Cutlass Supreme range includes two wheel diameters, the rim must be confirmed before focusing on sidewall style or brand. Looking at the wheel itself or reading the size on the current tire is usually the quickest check, especially on cars that may have received aftermarket wheels or replacement factory-style wheels over time.
Do all 1988 Oldsmobile Cutlass Supreme sub-models use the same tire size?
No. The 1988 Oldsmobile Cutlass Supreme has split fitment across its sub-models. Base, Classic (FWD), Classic Brougham, and SL models use 14-inch radial sizes, while the Indy 500 Pace Car and International use 215/65R15 on 15-inch rims.
That difference matters because a 14-inch tire choice cannot simply be treated as interchangeable with a 15-inch setup. Once the sub-model is identified, the buyer can narrow the correct size family and then compare the available whitewall, redline, blackwall, raised white letter, or OWL options that suit the car’s intended appearance.
Choosing the Right Tire
What should I consider when choosing a tire for a 1988 Oldsmobile Cutlass Supreme?
Start with the exact size and rim diameter that belong on the specific 1988 Oldsmobile Cutlass Supreme sub-model. This car uses radial tires only, but fitment still varies between 14-inch applications using 195/75R14 or 205/70R14 and 15-inch applications using 215/65R15.
After size is settled, compare the visual character and specifications of the available tires. Whitewall styles suit a more formal Cutlass presentation, while redline, raised white letter, blackwall, or OWL choices lean sportier. Rim-width compatibility, load capacity at stated pressure, and the car’s intended use as a cruiser, show car, or regular driver also deserve attention.
What sidewall styles are available for 1988 Oldsmobile Cutlass Supreme tires?
Sidewall choices for the 1988 Oldsmobile Cutlass Supreme include wide whitewall, narrow whitewall, redline, dual redline, blackwall, RWL, and OWL, depending on the tire size. The 14-inch sizes lean more heavily toward whitewall, redline, and blackwall options, while the 15-inch size includes RWL, OWL, redline, and wide whitewall choices.
That variety lets the tire shape the car’s overall presentation. A wide whitewall tends to suit a more formal, restoration-oriented look, while redline or raised white letter styles bring out the sportier side of the Cutlass Supreme. Matching the sidewall treatment to the wheel design and trim level usually produces a more coherent finished appearance.
What brands offer tires for the 1988 Oldsmobile Cutlass Supreme?
Tires for the 1988 Oldsmobile Cutlass Supreme are available from Coker Classic, Tornel, Maxxis, Travelstar, BFGoodrich, Michelin, Goodyear, and Cooper. Brand availability depends on the tire size, with the 14-inch fitments drawing from one mix of manufacturers and the 15-inch 215/65R15 fitment drawing from another.
Choosing among brands is less about ranking names and more about matching the right combination of size, sidewall style, tire series, and wheel compatibility. Some options emphasize a formal whitewall look, others bring in redline or raised white letter styling, and some have narrower or broader rim-width ranges that should be checked against the wheel on the car.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Oldsmobile Cutlass Supreme?
A period-style tire for a 1988 Oldsmobile Cutlass Supreme starts with the correct radial size for the exact sub-model and wheel diameter. From there, the appearance choice usually comes down to whether the car is being presented as a more formal Cutlass Supreme with whitewall styling or as a sportier version using redline, RWL, OWL, or blackwall treatment.
The most convincing result usually comes from matching the tire’s sidewall character to the trim, wheel design, and overall direction of the car rather than choosing by size alone. When exact originality matters, factory literature, original photos, and marque-specific references are useful for confirming which visual style best suits a particular Cutlass Supreme.
How does tire construction affect the appearance of a restored 1988 Oldsmobile Cutlass Supreme?
On a restored 1988 Oldsmobile Cutlass Supreme, construction is straightforward because all primary fitments are radial. The visual difference comes less from bias-ply versus radial and more from the radial’s sidewall treatment, profile, and tire series, which can shift the car toward a formal boulevard look or a more assertive late-1980s performance look.
That means appearance decisions should focus on the details the eye actually sees. A wide whitewall can soften the car’s stance, while redline, dual redline, blackwall, RWL, or OWL options change the visual tone dramatically. The correct size and wheel diameter still come first, since an appealing sidewall treatment cannot compensate for the wrong fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Oldsmobile Cutlass Supreme?
Yes. Modifications can change tire fitment on a 1988 Oldsmobile Cutlass Supreme even when the size sounds close to the original. Aftermarket wheels, altered wheel width, suspension changes, lowering, or body and brake modifications can all affect clearance and the range of tire sizes that work safely on the car.
That is especially important here because the Cutlass Supreme family already spans both 14-inch and 15-inch fitments. A car that has been changed from its original wheel package should be checked for actual wheel diameter, wheel width, and steering or fender clearance before selecting a replacement tire based only on model year and trim name.
What should I inspect before driving a 1988 Oldsmobile Cutlass Supreme on new tires?
Before driving a 1988 Oldsmobile Cutlass Supreme on new tires, inspect the wheels for the correct diameter and condition, confirm lug hardware and valve stems are sound, and make sure the tires are inflated appropriately for the application. It also helps to verify that the chosen size matches the car’s actual wheel and sub-model setup.
Once the tires are mounted, look for proper clearance at full steering lock and through normal suspension movement. A short initial drive should be followed by another visual check for rubbing, air loss, or uneven seating. On a collector car that sees limited use, continuing to monitor pressure and sidewall condition remains just as important.
How should tires on a collector 1988 Oldsmobile Cutlass Supreme be maintained?
Tires on a collector 1988 Oldsmobile Cutlass Supreme should be maintained with regular pressure checks, visual inspections for cracking, bulges, cuts, and uneven wear, and periodic movement of the car so one area of the tread is not loaded for long periods. Low-mileage use does not eliminate the need for routine tire attention.
Storage conditions matter almost as much as mileage. Keeping the car away from prolonged sunlight, moisture, heat, and ozone sources helps preserve the rubber, especially on specialty whitewall or redline tires. Before any longer drive, it is wise to recheck inflation, tread condition, and general age-related deterioration rather than assuming a seldom-driven tire is road-ready.
