The 1988 Buick Regal came from Buick’s rear-wheel-drive G-body era, a period that blended traditional American coupe and sedan proportions with a more modern late-1980s ride and handling feel. That makes tire choice on this car especially important, because wheel and trim combinations can change the fitment. The 1988 Buick Regal uses radial tires in two primary sizes, 195/70R15 and 205/70R14, depending on the wheel setup. Available choices range from blackwall touring-style radials to narrow whitewall, redline, dual-redline, and raised white letter options. The right pick depends on confirming the car’s actual rim diameter first, then deciding whether appearance, restoration style, or general road use matters most.
Which Tire Size Is Right for The 1988 Buick Regal
The 1988 Buick Regal uses two primary tire sizes, and the first step is confirming whether the car has 14-inch or 15-inch wheels. Both sizes are radial fitments, but they do not use the same rim diameter. Because both Custom and Limited models can appear with either size, the real decision starts at the wheel itself, then moves to sidewall style, brand, and the overall look you want from the car.
195/70R15 is a metric radial size in which 195 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 15 is the rim diameter in inches. On a 1988 Buick Regal, this size belongs to a 15-inch wheel setup and reflects the more modern sizing language common by the late 1980s. Michelin XWX is available in this fitment with a blackwall presentation. This size is worth considering when the car already wears 15-inch rims and you want to preserve the intended wheel diameter without mixing fitments.
205/70R14 is a metric radial size with a 205-millimeter nominal section width, a 70-series profile, radial construction, and a 14-inch rim diameter. For the 1988 Buick Regal, this size opens up the broadest range of visual and brand choices, including blackwall, narrow whitewall, redline, dual-redline, and raised white letter styles. Available series include Michelin XWX, BFGoodrich Radial T/A, BFGoodrich Silvertown Radial, and Maxxis Classic Whitewall MA-1. It is the size to evaluate when your Regal has 14-inch wheels and you want more flexibility in appearance and tire character.
Tire fitment on the 1988 Buick Regal is straightforward in one sense and easy to overlook in another: both covered sub-models can use either primary tire size. That means checking the exact sub-model alone is not enough, and the wheel diameter on the car matters just as much before selecting tires.

1988 Buick Regal Custom
The 1988 Buick Regal Custom can use either of the Regal’s two radial tire sizes, depending on the wheel setup on the car. Tire selection starts by confirming whether it wears 14-inch or 15-inch rims, then narrowing the choice by sidewall style and brand preference.
The 1988 Buick Regal Limited also appears with either of the two primary radial sizes rather than one exclusive fitment. That makes wheel verification especially important, followed by choosing the look and tire series that best suit a more stock-style appearance or a more performance-oriented 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.

Tire Size & Fitment
What tire size fits a 1988 Buick Regal?
A 1988 Buick Regal uses one of two radial tire sizes: 195/70R15 or 205/70R14. Both sizes are correct for this model year, but they do not mount on the same wheel diameter, so they are tied to the actual wheel setup on the car rather than a single universal fitment.
That means the best starting point is the wheel itself, not the trim badge alone. Before choosing tires, check whether the Regal has 14-inch or 15-inch rims and confirm that the wheels are the ones currently intended for the car. After that, compare the available sidewall styles, brands, and tire series within the correct size.
What size rim does a 1988 Buick Regal use?
The 1988 Buick Regal uses either a 14-inch or 15-inch rim, depending on the tire size on the car. A 205/70R14 tire belongs on a 14-inch wheel, while a 195/70R15 tire belongs on a 15-inch wheel. Both fitments are radial and are used on this exact year and model.
Because the Regal can appear with either rim diameter, checking the existing wheel is essential before ordering tires. Look at the tire sidewall, measure the wheel if needed, and make sure the car has not been changed to an aftermarket setup over the years. Confirming rim diameter first prevents choosing the right tire size for the wrong wheel.
Do all 1988 Buick Regal sub-models use the same tire size?
No single tire size covers every 1988 Buick Regal in a way that removes the need to check the car. Both the Custom and Limited can use 195/70R15 or 205/70R14, so the sub-model name alone does not tell the whole fitment story. Wheel diameter remains part of the decision.
That is why a Regal owner should verify the actual wheel and tire combination on the car before focusing on brand or appearance. A Custom and a Limited may both be correct with either size, but a 14-inch tire cannot be used on a 15-inch wheel, and a 15-inch tire cannot be used on a 14-inch wheel.
Choosing the Right Tire
What should I consider when choosing a 1988 Buick Regal tire?
Start with the correct size for the wheel on the car: 195/70R15 for a 15-inch rim or 205/70R14 for a 14-inch rim. From there, the main selection points are construction, brand, tire series, sidewall appearance, and any rim-width and load details that matter for the specific product you are considering.
Appearance plays a bigger role on this Regal than many modern vehicles because the 205/70R14 fitment is available in several visual styles. A blackwall can keep the presentation understated, while narrow whitewall, redline, dual-redline, or raised white letter tires can move the car toward a more customized or period-flavored look. Matching the tire to the car’s intended use and visual goal usually narrows the choice quickly.
What sidewall styles are available for 1988 Buick Regal tires?
Sidewall choices for the 1988 Buick Regal vary by tire size. In 205/70R14, available styles include blackwall, narrow whitewall, redline, dual-redline, and raised white letter. In 195/70R15, the available option here is a blackwall Michelin XWX, so the visual selection is much narrower on the 15-inch fitment.
That difference makes wheel diameter part of the appearance decision as well as the fitment decision. Owners seeking a cleaner late-1980s touring look may prefer blackwalls, while those leaning toward a more customized or enthusiast presentation may focus on the 14-inch choices. The key is choosing the sidewall treatment only after confirming the correct wheel size already on the car.
What brands offer tires for the 1988 Buick Regal?
Tires for the 1988 Buick Regal are available from Michelin, BFGoodrich, and Maxxis in the applicable sizes. Michelin appears in both primary fitments through the XWX line, while BFGoodrich and Maxxis expand the 205/70R14 selection with additional sidewall treatments and series aimed at different visual preferences.
Brand choice should be weighed alongside the rest of the tire’s specifications instead of treated as the whole decision. One Regal owner may want the simpler blackwall appearance of an XWX, while another may be looking for raised white letters, redlines, or a whitewall presentation in 205/70R14. Once the wheel diameter is confirmed, the product grid becomes much easier to sort by purpose.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Buick Regal?
A period-style choice for a 1988 Buick Regal starts with using the correct wheel diameter and tire size already associated with the car, either 195/70R15 or 205/70R14. From there, the visual direction matters most. Blackwall tires suit a restrained late-1980s look, while whitewall, redline, dual-redline, or raised white letter designs create a more styled presentation.
The most appropriate choice depends on how the Regal is being interpreted. A stock-appearing driver may lean toward a simpler sidewall treatment, while a more personalized build may call for something more expressive. When exact originality matters, it is smart to compare the tire choice against Buick literature, original photos, or marque-specific restoration references before settling on a final look.
How does tire construction affect the appearance of a restored 1988 Buick Regal?
On a 1988 Buick Regal, construction is less of a visual dividing line than it would be on an earlier collector car because the primary fitments are already radial. The appearance difference comes more from the sidewall itself, such as blackwall, narrow whitewall, redline, dual-redline, or raised white letter styling, and from the overall character of the tire series selected.
That gives a restored Regal owner room to shape the car’s look without moving away from the correct basic construction type. A subdued touring-style blackwall keeps the car visually clean, while redlines or raised white letters make a much stronger statement. Since both size and rim diameter still govern fitment, appearance should be the final step after the wheel setup is confirmed.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Buick Regal?
Yes, modifications can affect tire fitment on a 1988 Buick Regal even when the tire size itself is one of the correct sizes. Aftermarket wheels, changes in wheel width, altered offset, suspension work, or ride-height changes can all influence how a tire sits in the wheel opening and how much steering or fender clearance remains.
A Regal that has been lowered or fitted with non-stock wheels should be checked more carefully before settling on a tire. Verify the actual rim diameter first, then inspect clearance at full steering lock and through suspension travel. Even a correct 195/70R15 or 205/70R14 can require extra attention when the car no longer uses its original-style wheel and suspension layout.
What should I inspect before driving a 1988 Buick Regal on new tires?
Before driving a 1988 Buick Regal on new tires, inspect the wheels, valve stems, lug hardware, and overall tire pressure, then look closely at suspension and steering condition. It also helps to confirm that the tire size matches the wheel diameter and that the tire sits properly without rubbing at the fender, frame, or suspension components.
A short, careful test drive is the best next step. Listen for rubbing, feel for vibration, and recheck pressure after the first miles if the car has been sitting or recently serviced. On a collector-era Regal, tire installation is also a good time to inspect alignment condition and look for old wheel damage that could affect ride quality.
How should tires on a collector 1988 Buick Regal be maintained?
Tires on a collector 1988 Buick Regal should be maintained with regular pressure checks, visual inspections, and attention to age as well as tread depth. Because many Regals are driven less than modern daily vehicles, sidewall cracking, flat spotting from storage, and slow air loss can become more important than simple mileage wear.
Good storage habits help preserve both appearance and serviceability. Keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources, and inspect the tires before longer drives even if they still look presentable at a glance. Rotating use, maintaining proper inflation, and checking for cuts, bulges, or vibration can prevent surprises once the car returns to the road.
