The 1988 Buick Riviera came from the front-wheel-drive, downsized phase of Buick personal luxury coupes, blending a distinctly late-1980s profile with comfort-focused road manners. It is a Riviera that often attracts buyers who want the right balance between original character and confident road use. Tire fitment splits by sub-model, with the Luxury using 205/75R14 radials and the T-Type using 215/65R15 radials. That creates a real choice not just in size, but in sidewall presentation, from whitewalls to redlines and raised white letter styles. The key is confirming the exact sub-model and wheel diameter before choosing a tire that suits restoration goals or regular driving.
Which Tire Size Is Right for The 1988 Buick Riviera
The 1988 Buick Riviera uses two primary tire sizes, and the correct one depends on the sub-model and wheel diameter. The Luxury uses a 14-inch radial fitment, while the T-Type uses a 15-inch radial fitment, so the first step is confirming which Riviera you have and verifying the wheel size currently on the car before comparing sidewall style, brand, or tire series.
205/75R14 is a metric radial size where 205 is the section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 14 is the rim diameter in inches. On the 1988 Buick Riviera, this size belongs to the Luxury sub-model and keeps the car in a traditional passenger-car radial format. Available choices include narrow whitewall and wide whitewall styles, along with redline options, across brands such as American Classic, Coker Classic, Maxxis, BFGoodrich, Tornel, and Travelstar. It is the right size to evaluate when the Riviera has the 14-inch wheel setup and a more classic luxury appearance is the goal.
215/65R15 is a metric radial size with a 215-millimeter section width, a 65-series profile, radial construction, and a 15-inch rim diameter. For the 1988 Buick Riviera, this size is tied to the T-Type and gives that sub-model a distinct fitment from the Luxury version. Product choices include raised white letter, redline, and wide whitewall treatments from Goodyear, Cooper, and BFGoodrich in series such as Eagle GT, Cobra Radial G/T, Radial T/A, and Silvertown Radial. This is the size to focus on when the car retains its 15-inch wheel package or when the buyer wants a more performance-leaning visual style.
Sub-model fitment matters on the 1988 Buick Riviera because the covered versions do not share the same tire size or wheel diameter. Identifying whether the car is a Luxury or a T-Type is the first step before comparing brands, sidewall styles, or other tire details.

1988 Buick Riviera Luxury
The 1988 Buick Riviera Luxury uses a 205/75R14 radial tire on a 14-inch wheel. That points the selection process toward classic passenger-car radial choices, especially if the goal is a whitewall or other traditional sidewall treatment that suits the Riviera's luxury-coupe character.
The 1988 Buick Riviera T-Type uses a 215/65R15 radial tire on a 15-inch wheel. That fitment opens the door to a different mix of sidewall and series choices, so confirming the wheel setup is especially important before selecting a tire with a more touring or performance-oriented 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.

Common 1988 Buick Riviera tire questions usually come down to identifying the correct sub-model, confirming 14-inch versus 15-inch wheel fitment, and choosing among radial sidewall styles and tire series that suit the car's appearance and road use.
Tire Size & Fitment
What tire size fits a 1988 Buick Riviera?
A 1988 Buick Riviera uses one of two radial tire sizes, depending on the sub-model. The Riviera Luxury uses 205/75R14, while the Riviera T-Type uses 215/65R15. Those sizes are tied to different wheel diameters, so they are not simply two interchangeable choices for the same setup.
The practical first step is confirming whether the car is a Luxury or a T-Type and then checking the wheel diameter actually on the car today. A Riviera that has been changed to different wheels over the years may no longer match its original sub-model fitment, so tire selection should follow the current wheel and vehicle setup.
What size rim does a 1988 Buick Riviera use?
The 1988 Buick Riviera uses either a 14-inch or 15-inch rim, depending on sub-model. The Luxury pairs with a 14-inch wheel and the 205/75R14 tire size, while the T-Type uses a 15-inch wheel with 215/65R15 tires. Rim diameter is the key fitment difference between the two covered Riviera versions.
That means the wheel diameter should be checked before anything else, especially on a car that has had wheels replaced or upgraded. Tire size, sidewall style, and series selection all come after that basic confirmation, since a 14-inch tire cannot be mounted on a 15-inch wheel and vice versa.
Do all 1988 Buick Riviera sub-models use the same tire size?
No. The 1988 Buick Riviera Luxury and 1988 Buick Riviera T-Type use different tire sizes. The Luxury uses 205/75R14, while the T-Type uses 215/65R15. Both are radial constructions, but they are matched to different wheel diameters and lead to different product choices.
That difference matters because it changes more than just the numbers on the sidewall. It also changes which tire series, sidewall treatments, and rim-width specifications come into play. Once the exact sub-model and wheel size are confirmed, choosing among the available radial options becomes much more straightforward.
Choosing the Right Tire
What should I consider when choosing a tire for a 1988 Buick Riviera?
Start with the correct sub-model and size: 205/75R14 for the Luxury and 215/65R15 for the T-Type. From there, the important comparisons are radial construction details, wheel compatibility, sidewall style, tire series, and whether the car is being kept close to a traditional luxury presentation or given a more performance-oriented look.
A whitewall-equipped Riviera may call for a very different visual result than a T-Type wearing raised white letter or redline tires. It also helps to compare the wheel width requirements of the tire being considered, especially if the car has replacement wheels rather than its original factory-diameter rim.
What sidewall styles are available for 1988 Buick Riviera tires?
Sidewall choices for 1988 Buick Riviera tires include narrow whitewall, wide whitewall, redline, OWL, and RWL depending on the tire size. The 205/75R14 Luxury fitment leans strongly toward whitewall and redline options, while the 215/65R15 T-Type size includes redline, wide whitewall, OWL, and raised white letter styles.
That variety gives the Riviera owner some real flexibility in appearance without changing the tire size itself. A wider whitewall creates a more traditional luxury-coupe look, while redline, OWL, or raised white letter styles can give the car a noticeably sportier late-1980s presentation when used on the proper wheel size.
What brands offer tires for the 1988 Buick Riviera?
Tires for the 1988 Buick Riviera are available from American Classic, Coker Classic, Maxxis, BFGoodrich, Tornel, Travelstar, Goodyear, and Cooper, depending on the size. Brand availability changes with fitment, so the 205/75R14 Luxury size and the 215/65R15 T-Type size do not share the exact same brand mix.
The better way to compare these options is by looking at what each brand offers within the correct Riviera size, including sidewall treatment, tire series, and wheel-width suitability. That keeps the decision focused on the car's fitment and appearance goals instead of treating brand name alone as the deciding factor.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Buick Riviera?
A period-style 1988 Buick Riviera tire choice starts with the correct sub-model size and wheel diameter. The Luxury points toward 205/75R14 radial options with traditional whitewall or redline presentations, while the T-Type uses 215/65R15 and can lean toward whitewall, redline, OWL, or raised white letter styles depending on the look being pursued.
The most convincing result usually comes from matching the tire's sidewall treatment to the personality of the specific car rather than choosing by size alone. If exact originality matters, the final appearance choice should be checked against marque references, factory literature, or well-preserved examples before committing to one style.
How does tire construction affect the appearance of a restored 1988 Buick Riviera?
On the 1988 Buick Riviera, the covered primary fitments are radial tires, so the visual question is less about bias-ply versus radial and more about sidewall treatment, profile, and series. The Riviera's late-1980s character can look markedly different with a wide whitewall than it does with redlines, OWL, or raised white letter tires.
That makes construction consistency straightforward, since both sub-model fitments stay within radial form, but appearance still changes significantly from one tire style to another. Choosing carefully helps the car read more as formal personal luxury or more performance-oriented, depending on whether it is a Luxury or T-Type presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Buick Riviera?
Yes. Modifications can change tire fitment on a 1988 Buick Riviera even when the selected tire matches one of the original sizes. Aftermarket wheels, changes in wheel width, altered offset, suspension work, or body changes can all affect how a 205/75R14 or 215/65R15 tire sits in the wheel opening.
That is why the current car should be checked rather than assuming every Riviera still matches its original configuration. Verifying wheel diameter, wheel width, clearance at full steering lock, and space around the fenders and suspension helps prevent fitment surprises once the new tires are mounted.
What should I inspect before driving a 1988 Buick Riviera on new tires?
Before driving a 1988 Buick Riviera on new tires, inspect the wheels for damage, confirm the tires are mounted in the correct size for the sub-model, and make sure inflation is set appropriately for the tire being used. It is also wise to look over suspension and steering components on a car that may have seen long storage or intermittent use.
A road-ready check should also include tread-to-body clearance, valve stem condition, and any signs of rubbing once the car is on the ground and turned lock to lock. A short, careful test drive helps confirm there are no vibration, clearance, or handling issues that need attention before longer use.
How should 1988 Buick Riviera tires be maintained?
1988 Buick Riviera tires should be maintained with regular pressure checks, visual inspection of the tread and sidewalls, and prompt attention to cuts, bulges, cracking, or unexplained air loss. Collector cars and low-mileage cars deserve extra attention because tires can age even when tread wear appears minimal.
Storage conditions matter as much as mileage on a Riviera that is not driven often. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires, and periodic inspection remains important even when the car spends much of its time parked indoors.
