The 1987 Oldsmobile 98 came from the final era of traditional American full-size comfort, when large front-drive sedans still emphasized quiet road manners, formal styling, and a distinctly upscale presence. Buyers looking after one today are often balancing originality, ride character, and the visual statement the tire makes on a long, low luxury car. The 1987 Oldsmobile 98 uses radial tires in two primary sizes, 205/75R14 and 215/65R15, so the first step is confirming which wheel diameter is on the car. From there, the choice shifts to whitewall, redline, or raised-letter styling and selecting a tire that suits restoration goals as well as real road use.
Which Tire Size Is Right for The 1987 Oldsmobile 98
Two primary tire sizes apply to the 1987 Oldsmobile 98, and both are radial constructions. The key difference is wheel diameter, since one size fits a 14-inch rim and the other fits a 15-inch rim. Every covered sub-model can use either size, so the most important step is confirming which wheels are actually on the car before comparing sidewall style, tire series, and brand options.
Fit(s): Regency, Regency Brougham, Regency Grande, and Regency Touring
Construction: Radial|Rim: 14 in
205/75R14 is a metric radial size in which 205 identifies the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On a 1987 Oldsmobile 98, this size suits buyers who are staying with a traditional full-profile radial presentation on a 14-inch wheel. Available choices include American Classic, Coker Classic, BFGoodrich, Maxxis, Tornel, and Travelstar, with narrow whitewall, wide whitewall, and redline sidewall treatments. It is a strong fitment starting point for owners focused on luxury-car appearance and period-style road manners.

215/65R15 is also a metric radial size, with 215 as the nominal section width in millimeters, 65 as the aspect ratio, R for radial construction, and 15 for the wheel diameter in inches. For the 1987 Oldsmobile 98, this size belongs on a 15-inch rim and gives the buyer a different mix of styling choices than the 14-inch fitment. Products in this size include BFGoodrich, Goodyear, and Cooper options with wide whitewall, redline, OWL, and raised white letter sidewalls. It is worth evaluating carefully if the car has sportier-looking wheels or later wheel changes.
Fitment is fairly straightforward across the covered 1987 Oldsmobile 98 sub-models because each one uses the same two radial tire sizes. What matters most is not the trim name, but confirming whether the car is wearing 14-inch or 15-inch wheels before choosing a tire.

1987 Oldsmobile 98 Regency
The 1987 Oldsmobile 98 Regency uses the same two radial fitments found across the broader 98 range. Tire selection comes down to verifying wheel diameter first, then choosing the sidewall treatment and tire series that best match the car's appearance and intended use.
The 1987 Oldsmobile 98 Regency Brougham shares the same 14-inch and 15-inch radial tire fitment paths as the other covered sub-models. That makes wheel confirmation the key step, followed by deciding whether a whitewall, redline, or lettered sidewall better suits the car's presentation.
The 1987 Oldsmobile 98 Regency Grande follows the same basic tire-fitment pattern, with both available radial sizes depending on wheel setup. Choosing the right tire means matching the correct rim diameter first and then narrowing the options by brand, series, and sidewall style.
The 1987 Oldsmobile 98 Regency Touring uses the same pair of radial size choices as the rest of the covered lineup. Once the wheel diameter is confirmed, the next decision is whether the car should lean toward a traditional whitewall look or a more performance-flavored redline or raised-letter presentation.
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.

Owners of a 1987 Oldsmobile 98 usually need to sort out wheel diameter first, then compare radial size, sidewall style, and product character. These FAQs focus on exact fitment, 14-inch versus 15-inch wheels, appearance choices, and the checks worth making before the car goes back on the road.
Tire Size & Fitment
What tire size fits a 1987 Oldsmobile 98?
The 1987 Oldsmobile 98 uses two primary tire sizes: 205/75R14 and 215/65R15. Both are radial tire fitments, but they are not interchangeable as primary selections without first matching the wheel diameter on the car, since one size is for a 14-inch rim and the other is for a 15-inch rim.
The practical decision starts at the wheel, not the trim name, because every covered Regency, Regency Brougham, Regency Grande, and Regency Touring can use both fitment paths. Check the actual wheels on the car, especially if it has had replacements over the years, then compare available sidewall styles, tire series, and rim-width specifications within the correct size.
What size rim does a 1987 Oldsmobile 98 use?
A 1987 Oldsmobile 98 can use either a 14-inch or a 15-inch rim, depending on which tire size is on the car. The 205/75R14 size belongs on a 14-inch wheel, while the 215/65R15 size belongs on a 15-inch wheel. Both fitments are radial constructions.
That makes wheel confirmation the first step before ordering tires. A quick visual assumption is not always enough on an older luxury car, since aftermarket wheels or later substitutions are common. Read the existing tire size, verify the wheel diameter directly, and then make sure the wheel width falls within the range supported by the tire you are considering.
Do all 1987 Oldsmobile 98 sub-models use the same tire size?
The covered 1987 Oldsmobile 98 sub-models all share the same fitment pattern. Regency, Regency Brougham, Regency Grande, and Regency Touring each use the same two radial tire sizes: 205/75R14 and 215/65R15. The variation is tied to wheel setup rather than to one sub-model having a completely different tire family.
That means the sub-model badge alone does not settle the tire question. The safer approach is to confirm which wheels are actually installed, then choose within the correct size based on sidewall appearance and the kind of use the car sees. This is especially important if the 98 has been restored, personalized, or fitted with replacement wheels at some point.
Choosing the Right Tire
What should I consider when choosing a 205/75R14 tire for a 1987 Oldsmobile 98?
Start with the fact that 205/75R14 is a radial tire for a 14-inch wheel, then compare the choices within that size. Available options differ by brand, tire series, sidewall treatment, rim-width specification, weight, and load capacity, so the real choice is less about fitment format and more about the kind of appearance and use you want.
This size offers a broad spread of luxury-oriented visual choices, including narrow whitewall, wide whitewall, and redline designs from brands such as American Classic, Coker Classic, BFGoodrich, Maxxis, Tornel, and Travelstar. Match the sidewall style to the car's presentation, then confirm wheel width and other tire specs so the selection suits the actual wheel and driving conditions.
What sidewall styles are available for 1987 Oldsmobile 98 tires?
Several sidewall styles are available for the 1987 Oldsmobile 98, depending on tire size. The 205/75R14 fitment includes narrow whitewall, wide whitewall, and redline choices, while 215/65R15 adds wide whitewall, redline, OWL, and raised white letter options. Both sizes remain radial constructions, but the visual effect can be very different.
That sidewall decision has a big influence on how the car presents. Whitewalls usually support a more formal luxury look, while redline or lettered sidewalls can give the car a more assertive period feel. Once the correct wheel diameter is confirmed, narrowing the selection by sidewall style is often the easiest way to choose a tire that suits the car.
What brands offer tires for the 1987 Oldsmobile 98?
Tire choices for the 1987 Oldsmobile 98 include American Classic, Coker Classic, Maxxis, BFGoodrich, Tornel, Travelstar, Goodyear, and Cooper, depending on the size selected. The 205/75R14 fitment has the broader brand spread, while 215/65R15 focuses on BFGoodrich, Goodyear, and Cooper offerings with a more concentrated set of styles.
Brand alone should not be the only filter. It helps to compare which series each brand offers in the correct size, whether the sidewall style suits the car, and whether the wheel-width and load specifications align with the wheel setup. That approach keeps the choice grounded in fitment and appearance rather than treating every same-size tire as identical.
Restoration & Appearance
Which tire should I choose for a period-style 1987 Oldsmobile 98?
A period-style 1987 Oldsmobile 98 tire choice usually starts with the correct wheel diameter and then moves to sidewall presentation. In 205/75R14, the car has access to narrow whitewall, wide whitewall, and redline radial options, while 215/65R15 includes wide whitewall, redline, OWL, and raised white letter choices for a different visual direction.
For a formal luxury-sedan appearance, many owners gravitate toward whitewall styles because they complement the character of the car. A redline or lettered sidewall can also make sense if the goal is a more personalized late-1980s look. When exact originality matters, compare the tire choice against period photos, build paperwork, or marque-specific restoration references before deciding.
How does tire construction affect the appearance of a restored 1987 Oldsmobile 98?
On the 1987 Oldsmobile 98, the primary fitments are radial tires in both available sizes, so the appearance differences come more from size and sidewall treatment than from choosing between bias-ply and radial construction. A 14-inch whitewall radial can present the car differently from a 15-inch raised-letter or OWL radial, even within the same model family.
That means restoration-minded buyers should think about the whole visual package, including wheel diameter, sidewall width, and whether the car should read as formal, sporty, or personalized. Tire construction is already modern radial here, so the stronger appearance decisions involve the profile and sidewall style rather than converting from one construction type to another.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1987 Oldsmobile 98?
Yes, modifications can affect tire fitment on a 1987 Oldsmobile 98 even when the tire size itself is one of the correct primary options. Wheel changes, altered wheel width, suspension work, ride-height changes, or body repairs can all influence how a 205/75R14 or 215/65R15 tire sits and clears through steering and suspension travel.
That is why the actual car should be checked rather than relying only on the model name. A 15-inch wheel conversion, for example, changes the fitment path immediately, and a wheel with nonstandard width can narrow the safe tire choices further. Clearance around the fenders and suspension should always be verified before finalizing a replacement tire.
What should I inspect before driving a 1987 Oldsmobile 98 on new tires?
Before driving a 1987 Oldsmobile 98 on new tires, confirm that the installed tires match the wheel diameter and that inflation is set appropriately for the tire in use. It also helps to inspect the wheels for damage, check valve stems, and make sure the tires seat properly and turn freely without rubbing.
A collector-era car can have issues beyond the tires themselves, so it is worth looking over suspension wear, steering play, and brake condition before regular road use. After the first drives, recheck tire pressure and look for any sign of uneven clearance or contact. Catching those details early helps protect both the new tires and the car.
How should tires on a collector 1987 Oldsmobile 98 be maintained?
Tires on a collector 1987 Oldsmobile 98 should be maintained with regular pressure checks, visual inspections, and attention to age-related condition even if the car is driven sparingly. Sidewall cracking, bulges, cuts, air loss, and uneven wear matter just as much on a low-mileage collector sedan as they do on a frequently driven car.
Storage conditions also make a difference. Keeping the car away from prolonged sunlight, excess heat, standing moisture, and ozone sources can help preserve tire condition over time. It is also smart to inspect the tires before any longer outing rather than assuming low use means low risk, especially on an older luxury car that may sit for extended periods.
