The 1987 Oldsmobile Delta 88 sits in the final stretch of the traditional full-size American sedan era, blending front-wheel-drive practicality with the broad, comfortable road manners buyers expected from an Eighty Eight. For this exact model year, tire selection starts with two radial fitments: 205/75R14 and 215/65R15. That means the key decision is not only size, but also which wheel diameter your car actually carries. Available choices range from narrow and wide whitewalls to redlines, raised white letter styles, and classic touring or sport-flavored radial series. For a stock-appearing restoration or a road-use-minded driver, matching the tire to the car's wheels and intended presentation matters most.
Which Tire Size Is Right for The 1987 Oldsmobile Delta 88
The 1987 Oldsmobile Delta 88 uses two primary tire sizes, and both are radial fitments. The first step is confirming whether the car has 14-inch or 15-inch wheels, since 205/75R14 and 215/65R15 use different rim diameters even though their overall tire height is very close. Because both Royale and Royale Brougham can use either size, wheel verification matters more than trim name alone.
205/75R14 is a metric radial size in which 205 is the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 14 is the wheel diameter in inches. On the 1987 Oldsmobile Delta 88, this size supports a traditional full-size sedan look with a 14-inch wheel. Product choices include American Classic, Coker Classic, Maxxis, BFGoodrich, Tornel, and Travelstar, with sidewall treatments such as narrow whitewall, wide whitewall, and redline. It is a strong choice when the car retains 14-inch wheels and the owner wants broad appearance options within the correct size family.
215/65R15 is a metric radial size where 215 is the nominal section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 15 is the wheel diameter in inches. For the 1987 Oldsmobile Delta 88, this fitment moves to a 15-inch wheel while staying close in overall height to the 14-inch alternative. Available options include Goodyear, Cooper, and BFGoodrich, with sidewall styles such as OWL, RWL, redline, and wide whitewall across several radial series. This size is worth considering when the car is already equipped with 15-inch wheels and the buyer wants a more touring- or sport-oriented visual character.
Tire fitment is straightforward across the covered 1987 Oldsmobile Delta 88 sub-models because both Royale and Royale Brougham can use the same two radial sizes. The important check is the actual wheel diameter on the car, since either sub-model may be on a 14-inch or 15-inch setup.

1987 Oldsmobile Delta 88 Royale
The 1987 Oldsmobile Delta 88 Royale can use either of the model's two radial tire sizes, so trim name alone does not settle the fitment question. Tire selection comes down to confirming whether the car has 14-inch or 15-inch wheels, then choosing the sidewall style and tire series that best match the car's intended look.
The 1987 Oldsmobile Delta 88 Royale Brougham also uses the same two radial fitment paths found across this model year. That makes wheel diameter the key verification point before selecting between whitewall, redline, or lettered-sidewall tire options in the correct size.
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.

Common questions for the 1987 Oldsmobile Delta 88 usually center on choosing between the two correct tire sizes, confirming 14-inch versus 15-inch wheels, and sorting through whitewall, redline, and lettered radial options for the right road and restoration balance.
Tire Size & Fitment
What tire size fits a 1987 Oldsmobile Delta 88?
The 1987 Oldsmobile Delta 88 uses two primary tire sizes: 205/75R14 and 215/65R15. Both are radial fitments, and both are used within this exact model year. The two sizes are very similar in overall height, but they are built for different wheel diameters, so they are not interchangeable without the matching wheel.
Choosing the right one starts with checking the wheel on the car, not just the trim badge. A Delta 88 with 14-inch wheels needs the 205/75R14 size, while a car with 15-inch wheels needs 215/65R15. If the car has been changed from stock over the years, verify the actual wheel diameter and width before selecting a tire.
What size rim does a 1987 Oldsmobile Delta 88 use?
A 1987 Oldsmobile Delta 88 uses either a 14-inch or 15-inch rim, depending on which tire size is on the car. The 205/75R14 tire is matched to a 14-inch rim, and the 215/65R15 tire is matched to a 15-inch rim. Both sizes are correct fitment paths for this model year.
Rim diameter is the first thing to confirm because the two tire sizes do not mount on the same wheel. It also helps to check wheel width before final tire selection, especially if the car has replacement wheels. Looking at the size stamped on the existing tire sidewall and confirming the wheel itself can prevent ordering the right tire for the wrong rim.
Do all 1987 Oldsmobile Delta 88 sub-models use the same tire size?
The 1987 Oldsmobile Delta 88 Royale and Royale Brougham both use the same two primary radial tire sizes: 205/75R14 and 215/65R15. That means sub-model alone does not force one single tire size across the board. Either covered sub-model may be fitted with the 14-inch or 15-inch tire-and-wheel combination.
In practical terms, the trim name is less important than the actual wheels on the car today. A Royale Brougham is not automatically a 15-inch car, and a Royale is not automatically a 14-inch car. Before choosing a tire, inspect the current wheel diameter and confirm whether the car still carries its intended wheel setup or has been changed over time.
Choosing the Right Tire
What should I consider when choosing a tire for a 1987 Oldsmobile Delta 88?
Start with the correct size for the wheels on the car: 205/75R14 for 14-inch rims or 215/65R15 for 15-inch rims. From there, the main selection points are sidewall style, tire series, brand, and rim-width compatibility. On this Delta 88, available looks range from traditional whitewalls to redlines and raised white letter styles.
A stock-appearing sedan often looks best with a whitewall, while a more personalized or sport-flavored presentation may lean toward redline, OWL, or RWL sidewalls. It also helps to compare the tire's intended character with how the car is used, whether that is occasional cruising, show display, or regular fair-weather driving. Matching size first keeps the rest of the decision simple.
What sidewall styles are available for 1987 Oldsmobile Delta 88 tires?
The 1987 Oldsmobile Delta 88 has a wide spread of sidewall styles across its two tire sizes. In 205/75R14, choices include narrow whitewall, wide whitewall, and redline. In 215/65R15, available styles include wide whitewall, redline, OWL, and RWL, giving this model year both traditional and more performance-oriented visual options.
That variety lets the tire do a lot of the styling work on the car. Whitewalls usually suit a formal, full-size Oldsmobile presentation, while redlines and lettered sidewalls shift the look toward a more assertive late-1980s custom or sporty feel. The important step is to keep the sidewall decision inside the correct tire size and wheel diameter for the car.
What brands offer tires for the 1987 Oldsmobile Delta 88?
Available brands for the 1987 Oldsmobile Delta 88 include American Classic, Coker Classic, Maxxis, BFGoodrich, Tornel, Travelstar, Goodyear, and Cooper. Brand availability depends on the size. The 205/75R14 selection carries the broadest mix, while 215/65R15 includes Goodyear, Cooper, and BFGoodrich options in several visual styles.
The best use of that brand variety is comparison, not brand ranking. Some options lean toward classic whitewall presentation, while others focus on redline or raised white letter styling. Once the correct size is confirmed, compare sidewall treatment, tire series, and wheel-width compatibility to narrow the field in a way that suits the car's appearance and use.
Restoration & Appearance
Which tire should I choose for a period-style 1987 Oldsmobile Delta 88?
A period-style 1987 Oldsmobile Delta 88 usually starts with choosing the correct wheel diameter first, then selecting a radial tire whose sidewall treatment matches the car's character. Whitewall tires are available in both 205/75R14 and 215/65R15, making them a natural fit for a traditional full-size Oldsmobile look without assuming one exact original presentation for every car.
The final choice depends on how formal or personalized the car is meant to appear. A narrow or wide whitewall often supports a more stock-appearing sedan, while redline or lettered sidewalls create a different visual tone. When exact originality matters, compare the tire choice against vehicle-specific literature, surviving examples, or marque-club guidance before settling on one style.
How does tire construction affect the appearance of a restored 1987 Oldsmobile Delta 88?
Construction is straightforward on a 1987 Oldsmobile Delta 88 because both primary fitments are radial. That means the appearance difference comes less from bias-ply versus radial construction and more from the sidewall style, overall profile, and tire series chosen within the correct size. Whitewall, redline, OWL, and RWL treatments can all change the car's visual character noticeably.
For a restoration-minded owner, the goal is to keep the size and wheel relationship appropriate to the car while using the sidewall to shape the final presentation. A formal sedan can look very different on wide whitewalls than it does on raised white letters. Staying within the proper 14-inch or 15-inch fitment path preserves the car's stance and proportions more effectively than chasing style alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1987 Oldsmobile Delta 88?
Yes, modifications can affect tire fitment on a 1987 Oldsmobile Delta 88 even when the tire size itself is correct. Wheel swaps, altered ride height, suspension changes, or bodywork repairs can change the clearance relationship around the tire. That matters here because the car may already be using either a 14-inch or 15-inch wheel setup.
A careful check should include wheel diameter, wheel width, and visible clearance at the fender, steering, and suspension areas. The car may also have replacement wheels with different dimensions than expected. Looking over the full setup before mounting new tires helps avoid selecting a tire that matches the sidewall code but conflicts with the car's current hardware.
What should I inspect before driving a 1987 Oldsmobile Delta 88 on new tires?
Before road use, inspect the wheel condition, confirm the tire size matches the actual rim diameter, and make sure the tires are inflated properly for installation and initial service. It is also smart to check for uneven suspension wear, damaged valve stems, and any signs that the old tires were rubbing or wearing irregularly.
A short, careful test drive can reveal steering pull, vibration, or clearance issues that were not obvious while the car was parked. Collector-era full-size sedans often sit for long periods, so brake condition and general chassis health matter as much as the tires themselves. Catching those issues early gives the new tires the best chance to wear evenly and perform as intended.
How should tires on a collector 1987 Oldsmobile Delta 88 be maintained?
Tires on a collector 1987 Oldsmobile Delta 88 should be inspected regularly for pressure loss, sidewall cracking, bulges, cuts, and uneven tread wear. Cars that see limited mileage can still age their tires even when tread depth looks good. That makes visual inspection and routine pressure checks more important than mileage alone.
Storage habits also matter. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the tire sidewalls, especially on whitewall or specialty appearance tires. It also helps to move the car periodically and check alignment or suspension condition if unusual wear starts to appear. A low-use classic benefits from preventive inspection far more than a wait-until-there-is-a-problem approach.
