The 1989 Buick Riviera came from a period when personal luxury coupes were blending traditional Buick comfort with more modern front-wheel-drive packaging and sharper late-1980s styling. For owners today, that means tire selection is less about antique sizing and more about confirming the exact modern metric fitment used on the car. This Riviera uses radial 205/70R15 and 215/65R15 tire sizes on 15-inch rims, and both sizes appear across Luxury and T-Type models. Available choices range from blackwall, narrow whitewall, and wide whitewall designs to raised white letter and redline styles. The right pick depends on whether the goal is stock-like road use, a sportier look, or a more restoration-oriented presentation.
Which Tire Size Is Right for The 1989 Buick Riviera
The 1989 Buick Riviera uses two primary tire sizes, both in radial construction and both built for 15-inch rims. Because the Luxury and T-Type sub-models can use either 205/70R15 or 215/65R15, the first step is confirming the size already mounted on the car and matching it to the wheel setup. From there, the decision shifts to sidewall style, tire series, and the overall look and driving character you want.
205/70R15 is a metric radial size in which 205 identifies the nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 15 is the wheel diameter in inches. On a 1989 Buick Riviera, this size supports a more contemporary late-1980s fitment style while staying within the car's 15-inch wheel format. Available choices include blackwall, narrow whitewall, and wide whitewall designs from brands such as Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. It is a useful size to evaluate when appearance, rim-width compatibility, and driving intent all matter.
215/65R15 is also a metric radial size, with a 215-millimeter nominal section width, a 65-series profile, radial construction, and a 15-inch rim diameter. For the 1989 Buick Riviera, it keeps the same wheel diameter as the 205/70R15 option but changes the tire's proportions, so it should be matched to the actual wheel and vehicle setup already in use. Product choices include OWL, raised white letter, redline, and wide whitewall styles from Goodyear, Cooper, and BFGoodrich. This size is worth considering when the Riviera's look is part of the decision, especially on cars with a sportier or more customized presentation.
Tire fitment on the 1989 Buick Riviera is straightforward in one sense and still worth checking closely in another. Both Luxury and T-Type models can use the same two radial 15-inch tire sizes, so the real task is confirming which size is on the car before choosing a replacement.

1989 Buick Riviera Luxury
The 1989 Buick Riviera Luxury can use either of the two primary radial 15-inch tire sizes offered for this model year. That makes the selection less about trim level alone and more about verifying the wheels and existing setup before choosing between whitewall, blackwall, or other period-appropriate styling options.
The 1989 Buick Riviera T-Type also uses the same two radial tire sizes found on the Luxury model, both on 15-inch rims. Tire choice here comes down to confirming the actual size fitted to the car and deciding whether the goal is a sportier sidewall treatment or a more traditional Riviera appearance.
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 1989 Buick Riviera Tires for Sale
Available 1989 Buick Riviera tires cover both primary sizes with a wide spread of brands, series, and sidewall treatments.

These FAQs focus on the two tire sizes used on the 1989 Buick Riviera, how they relate to the car's 15-inch wheels, and how to choose among available radial, sidewall, and appearance options before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 1989 Buick Riviera?
The 1989 Buick Riviera uses two primary tire sizes: 205/70R15 and 215/65R15. Both are radial tire sizes built for 15-inch wheels, and both appear on Riviera models from this year, including the Luxury and T-Type sub-models.
That means the right replacement starts with confirming which size is already on the car rather than assuming one size fits every Riviera the same way. Checking the sidewall marking on the existing tires and verifying the wheel setup helps avoid mixing sizes or choosing a tire that does not match the car's current fitment.
What size rim does a 1989 Buick Riviera use?
The 1989 Buick Riviera uses a 15-inch rim diameter with both of its primary tire sizes. Whether the car is fitted with 205/70R15 or 215/65R15 tires, the wheel diameter remains 15 inches.
Wheel diameter is only one part of the fitment picture, so it is still smart to confirm wheel width before selecting a tire. Some available products in these sizes are intended for different rim-width ranges, and that can affect how the tire sits on the wheel and how well it suits the Riviera's current setup.
Do all 1989 Buick Riviera sub-models use the same tire size?
The 1989 Buick Riviera Luxury and 1989 Buick Riviera T-Type share the same two primary tire sizes: 205/70R15 and 215/65R15. In other words, sub-model alone does not narrow the fitment down to one single size.
Because both sub-models can use either size, the practical next step is to inspect the car itself. The existing tire sidewall, wheel width, and any past wheel changes matter more here than the trim badge, especially if the Riviera has been updated, restored, or altered from its earlier road-going setup.
Choosing the Right Tire
What should I consider when choosing a 1989 Buick Riviera tire?
Start with the correct size already fitted to the car, since the 1989 Buick Riviera uses either 205/70R15 or 215/65R15 on a 15-inch rim. After that, compare radial construction details, sidewall style, rim-width compatibility, and the overall look you want from the tire.
A Riviera aimed at a formal personal-luxury appearance may lean toward narrow or wide whitewalls, while a sportier presentation may point toward blackwall, OWL, RWL, or redline options. Product specifications such as load capacity and wheel-width range are also worth comparing so the tire matches both the vehicle and the wheel you are using.
What sidewall styles are available for 1989 Buick Riviera tires?
Sidewall choices for the 1989 Buick Riviera vary by tire size and product line. Across the available tires, the Riviera can be fitted with blackwall, narrow whitewall, wide whitewall, OWL, RWL, and redline sidewall treatments.
That variety gives the car very different visual character without changing the basic fitment category. A whitewall can support a more traditional Buick look, while OWL, RWL, redline, or blackwall designs can push the car toward a more performance-oriented or customized presentation, so the sidewall choice should match the Riviera's intended style.
What brands offer tires for the 1989 Buick Riviera?
The 1989 Buick Riviera has tire options from Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, Travelstar, Goodyear, Cooper, and BFGoodrich. Brand availability depends on whether the car uses 205/70R15 or 215/65R15.
Rather than choosing by brand name alone, compare how each option is configured in the correct size. The available Riviera tires differ by sidewall treatment, tire series, rim-width specification, and load figures, so the better comparison is which product best suits the car's current wheel setup, appearance goals, and intended road use.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Buick Riviera?
A period-style 1989 Buick Riviera tire choice usually begins with keeping the correct size already fitted to the car, either 205/70R15 or 215/65R15, and then selecting a sidewall treatment that suits the Riviera's late-1980s personal-luxury character. Whitewall options can support a more traditional presentation, while blackwall and lettered styles give a different look.
For a restoration-oriented car, appearance matters almost as much as fitment. It helps to compare the car's trim level, wheels, and overall finish before choosing between narrow whitewall, wide whitewall, redline, or raised white letter styles, especially if the goal is to capture a believable period feel rather than a generic replacement look.
How does tire construction affect the appearance of a restored 1989 Buick Riviera?
On a restored 1989 Buick Riviera, construction is less about bias-ply versus radial and more about choosing the right radial design for the car's era and presentation. Both primary Riviera sizes are radial, but the available products still vary significantly in sidewall styling and overall visual character.
That difference shows up quickly on a finished car. A wide whitewall can make the Riviera look more formal and luxury-oriented, while blackwall, OWL, RWL, or redline tires can shift the visual tone toward sport or custom style, so the tire should be chosen as part of the restoration's overall design rather than as an afterthought.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Buick Riviera?
Yes, modifications can affect tire fitment on a 1989 Buick Riviera even when the tire size appears correct on paper. Aftermarket wheels, changes in wheel width, altered offset, suspension work, or body and fender changes can all influence how a 205/70R15 or 215/65R15 tire sits on the car.
That is why a modified Riviera should be checked as an actual vehicle, not just as a year-make-model entry. Looking at steering clearance, suspension travel, and the space around the tire helps confirm whether the selected size and sidewall profile make sense for the way the car is currently configured.
What should I inspect before driving a 1989 Buick Riviera on new tires?
Before driving a 1989 Buick Riviera on new tires, inspect the wheels for correct diameter and condition, confirm that all four tires match the intended size, and make sure inflation is set appropriately for the tire being used. It is also smart to check for rubbing at the fenders and steering components.
A collector-era coupe that has spent time parked deserves a broader walkaround as well. Wheel hardware, suspension condition, alignment behavior, and any signs of fluid leaks or dragging brakes can affect how new tires behave, so taking time for a careful pre-road check helps the Riviera settle in properly on its replacement tires.
How should tires on a collector 1989 Buick Riviera be maintained?
Tires on a collector 1989 Buick Riviera should be checked regularly for air loss, tread wear, sidewall cracking, bulges, cuts, and any change in how the car feels on the road. Even a low-mileage Riviera can have tire issues simply from age, storage conditions, or long periods of inactivity.
Proper storage helps preserve the tires between drives. Keeping the car away from prolonged heat, direct sunlight, excess moisture, and ozone sources can reduce deterioration, and periodic inspection remains important because a Riviera that looks ready for the road may still be riding on tires that need closer attention before longer use.
