The 1988 Oldsmobile 98 belonged to the final era of large front-wheel-drive American luxury sedans, when comfort, trim level, and wheel package could noticeably change the look of the car. That matters when choosing tires for this model, because the 1988 Oldsmobile 98 uses four different radial sizes across Regency, Regency Brougham, and Regency Touring applications. The fitment story centers on confirming the exact sub-model and wheel diameter first, then choosing among metric radial options that range from traditional whitewall presentations to blackwall, redline, and raised white letter styles. For a restoration-minded car or a road-going cruiser, appearance and wheel compatibility both deserve equal attention.
Which Tire Size Is Right for The 1988 Oldsmobile 98
The 1988 Oldsmobile 98 uses four different primary tire sizes, and they do vary by sub-model and wheel diameter. Some versions use 14-inch wheels, some use 15-inch wheels, and the Regency Touring uses a 16-inch setup, so the first step is confirming the exact sub-model and the wheel currently on the car. Once that is settled, the choice becomes selecting the right radial tire style, sidewall treatment, and product character within the correct size.
205/70R15 is a metric radial size with a 205 millimeter section width, a 70-series aspect ratio, and fitment for a 15-inch rim. On the 1988 Oldsmobile 98, this size suits certain Regency applications and keeps the car in a modern radial format rather than an older bias-ply sizing system. Available choices include blackwall, narrow whitewall, and wide whitewall styles across brands such as Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. It is a useful size to evaluate when the car has 15-inch wheels and the goal is to balance luxury-sedan appearance with the tire presentation you want.
205/75R14 is a metric radial size that uses a 205 millimeter section width, a 75-series profile, and a 14-inch rim. This size appears on Regency and Regency Brougham applications, making it one of the key fitments for owners of standard wheel-package cars. Product choices are especially broad here, with narrow whitewall, wide whitewall, and redline options available from brands including American Classic, Coker Classic, Maxxis, BFGoodrich, Tornel, and Travelstar. It deserves close attention when preserving a more traditional late-1980s luxury look on a 14-inch wheel setup.
215/65R15 is a metric radial with a 215 millimeter section width, a 65-series profile, and a 15-inch rim diameter. On the 1988 Oldsmobile 98, it applies to certain Regency Brougham configurations and gives that sub-model a distinct 15-inch fitment path separate from the 14-inch alternatives. Available products include raised white letter, owl-style sidewalls, redline, and wide whitewall treatments from Goodyear, Cooper, and BFGoodrich across several series. This size is worth confirming carefully if the car is a Brougham, especially if wheel changes have been made over the years.
215/60R16 is a metric radial size that combines a 215 millimeter section width with a 60-series profile on a 16-inch rim. For the 1988 Oldsmobile 98, this size is tied to the Regency Touring and represents the most wheel-specific fitment in the lineup. The practical takeaway is less about sidewall-style comparison and more about making sure the car still carries its correct 16-inch wheel setup before selecting replacement tires. It is the right size to consider when maintaining the Touring model’s distinct configuration rather than substituting based on another 98 sub-model.
Sub-model fitment on the 1988 Oldsmobile 98 is not one-size-fits-all. Regency, Regency Brougham, and Regency Touring applications can use different tire sizes and different wheel diameters, so confirming the exact sub-model is the most important step before comparing products.

1988 Oldsmobile 98 Regency
The 1988 Oldsmobile 98 Regency uses radial fitments in either 205/70R15 or 205/75R14 depending on the wheel package. That makes wheel-diameter confirmation just as important as the trim name when choosing between traditional whitewall styles, blackwall options, or other radial presentations.
The 1988 Oldsmobile 98 Regency Brougham uses radial tire fitments that can fall into either 205/75R14 or 215/65R15. Tire selection starts with verifying whether the car is on a 14-inch or 15-inch wheel, then narrowing the choice by sidewall style and series character.
The 1988 Oldsmobile 98 Regency Touring uses a 215/60R16 radial fitment. For this sub-model, the main priority is preserving the correct 16-inch wheel setup and avoiding assumptions based on other 98 trims that use 14-inch or 15-inch tires.
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.
Best 1988 Oldsmobile 98 Tires for Sale
Available 1988 Oldsmobile 98 tire choices vary widely by size, with brands including Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, BFGoodrich, Goodyear, Cooper, Tornel, and Travelstar. Depending on the fitment, buyers can compare blackwall, narrow whitewall, wide whitewall, redline, and raised white letter styles across several radial tire series.
Owners of a 1988 Oldsmobile 98 usually need to sort out sub-model fitment, wheel diameter, sidewall style, and radial tire selection before choosing a replacement. These questions focus on the exact tire sizes, trim-level differences, appearance choices, and road-use checks that matter most.
Tire Size & Fitment
What tire size fits a 1988 Oldsmobile 98?
The 1988 Oldsmobile 98 uses four primary radial tire sizes: 205/70R15, 205/75R14, 215/65R15, and 215/60R16. The correct one depends on the exact sub-model and wheel package, with Regency, Regency Brougham, and Regency Touring applications not all sharing the same setup.
The most important step is confirming the trim and the wheel diameter actually on the car before comparing tires. A 14-inch, 15-inch, or 16-inch wheel changes the fitment path immediately, and many older luxury cars have seen wheel swaps over time that can make the current setup different from another 98 of the same year.
What size rim does a 1988 Oldsmobile 98 use?
A 1988 Oldsmobile 98 can use 14-inch, 15-inch, or 16-inch rims depending on the sub-model and tire size. The 205/75R14 uses a 14-inch rim, both 205/70R15 and 215/65R15 use 15-inch rims, and the 215/60R16 uses a 16-inch rim.
That means rim diameter should be verified before choosing replacement tires, especially on a car that may have had wheels changed during its life. Checking the size stamped on the wheel or confirming the size of the tire already mounted helps prevent ordering a tire that matches another Oldsmobile 98 trim but not the wheel on the car.
Do all 1988 Oldsmobile 98 sub-models use the same tire size?
No. The 1988 Oldsmobile 98 has different tire sizes across its sub-models. Regency uses 205/70R15 or 205/75R14, Regency Brougham uses 205/75R14 or 215/65R15, and Regency Touring uses 215/60R16.
That variation matters because a tire that suits one 98 sub-model may not match the rim diameter or intended setup of another. A Touring owner should start with the 16-inch wheel fitment, while Regency and Brougham owners should confirm whether the car carries a 14-inch or 15-inch wheel before narrowing the choice by sidewall style or tire series.
Choosing the Right Tire
What should I consider when choosing a 1988 Oldsmobile 98 tire?
Start with the correct size for the exact sub-model and wheel diameter, since the 1988 Oldsmobile 98 does not use one universal tire. From there, compare radial tire construction, rim-width compatibility where stated, load figures where shown, and the overall visual style that best suits the car.
A luxury-oriented 98 often looks very different depending on whether it wears a narrow whitewall, wide whitewall, blackwall, redline, or raised white letter sidewall. The right choice depends on whether the goal is a more formal restoration-style appearance, a sportier late-1980s presentation, or simply a tire that matches the car’s current wheel and trim character.
What sidewall styles are available for 1988 Oldsmobile 98 tires?
Sidewall choices for the 1988 Oldsmobile 98 include blackwall, narrow whitewall, wide whitewall, redline, OWL, and RWL depending on the tire size. Those options vary by fitment, so the sidewall styles available in 205/75R14 are not always the same as the choices offered in 215/65R15 or 205/70R15.
That variety gives owners room to shape the car’s appearance without changing the underlying size. Whitewalls typically support a more formal full-size luxury look, while blackwall, redline, and raised white letter styles create a different late-classic character. Once the correct size is confirmed, the sidewall treatment becomes one of the biggest appearance decisions on the page.
What brands offer tires for the 1988 Oldsmobile 98?
Available brands for 1988 Oldsmobile 98 tire sizes include Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, BFGoodrich, Goodyear, Cooper, Tornel, and Travelstar. Brand availability depends on the size, so some names appear only in certain 14-inch or 15-inch fitments.
Brand choice is best treated as part of a broader comparison rather than the first decision. After confirming the correct size, compare the brands that exist in that fitment by sidewall style, tire series, rim-width specification where listed, and load information where available. That approach keeps the focus on a tire that matches both the car and the owner’s intended look.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Oldsmobile 98?
A period-style 1988 Oldsmobile 98 tire starts with the correct factory-era size for the exact sub-model and wheel diameter, then narrows to a sidewall treatment that suits the car’s character. For many 98 applications, narrow whitewall or wide whitewall radials create the most traditional full-size Oldsmobile presentation, while some sizes also offer redline or raised white letter alternatives.
Appearance should be matched to the way the car is trimmed and used. A formal Regency or Regency Brougham may look most at home on whitewalls, while a different sidewall can change the visual balance noticeably. When originality matters at a high level, marque references and period photos are worth checking before settling on a particular brand or stripe style.
Does correct tire fitment matter for a 1988 Oldsmobile 98 restoration?
Yes. Correct tire fitment affects both the look and the stance of a restored 1988 Oldsmobile 98, and this model has multiple valid tire sizes depending on trim and wheel package. Using the wrong rim diameter or choosing a size intended for another sub-model can change the visual proportion of the car even before road manners are considered.
Restoration-minded owners should confirm the exact sub-model, wheel size, and current wheel setup before focusing on sidewall appearance. Once the correct size is established, the decision shifts to choosing a radial tire that complements the car’s level of trim and intended presentation, whether that means a cleaner blackwall look or a more formal whitewall finish.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Oldsmobile 98?
Yes. Modifications can affect tire fitment on a 1988 Oldsmobile 98, especially if the car has aftermarket wheels, altered ride height, suspension changes, or body work that changes available clearance. Since this model already spans 14-inch, 15-inch, and 16-inch fitments, even a modest wheel change can move the car away from its original tire path.
That is why the current setup should be checked rather than assuming the car still matches another 1988 98 of the same trim. Verify the wheel diameter first, then look at wheel width, steering clearance, and fender space before selecting a tire. Those checks are particularly important when moving between different visual styles or replacing wheels that were installed years ago.
What should I inspect before driving a 1988 Oldsmobile 98 on new tires?
Before driving a 1988 Oldsmobile 98 on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure the tires are mounted and inflated properly. It is also smart to check for suspension wear, steering looseness, and any signs that the old tires were rubbing or wearing unevenly.
A final walkaround should include sidewall condition, valve stems, lug-nut security, and visible clearance at the front wheels while turning. On an older full-size car, a short local test drive is a good way to confirm that the tires track properly and do not contact the fenders or suspension under normal steering and braking.
How should tires on a collector 1988 Oldsmobile 98 be maintained?
Tires on a collector 1988 Oldsmobile 98 should be kept at appropriate pressure, inspected regularly for cracking, bulges, cuts, uneven wear, and air loss, and driven often enough to avoid long periods of neglect. Low-mileage collector cars can age tires out before they wear them out, so visual condition matters as much as tread depth.
Storage conditions also play a role. Keeping the car away from prolonged sunlight, standing moisture, and ozone sources can help preserve the tires, especially on a car that spends long stretches parked. It is also wise to inspect the spare and recheck pressures before any longer drive, since a lightly used luxury car can hide tire aging easily.
