The 1982 Buick Riviera came from a period when personal luxury coupes still emphasized formal styling, comfort, and a tailored road presence. By the early 1980s, Riviera buyers expected a car that looked upscale at the curb and composed on the highway, so tire appearance mattered almost as much as basic fitment. This model uses 15-inch radial tire fitments in either 205/75R15 or GR70-15 form. That opens up a meaningful choice between modern metric whitewall and specialty sidewall options or vintage-style alphanumeric radial designs with period-flavored presentation. The right selection depends on whether the goal is a more traditional look, a specific sidewall treatment, or a careful match to the wheels already on the car.
Which Tire Size Is Right for The 1982 Buick Riviera
The 1982 Buick Riviera uses two primary tire sizes, and both are radial fitments on 15-inch wheels. Because the covered sub-models share these same sizes, the first step is confirming which tire format matches the wheel setup and appearance you want, then comparing sidewall style, tire series, and rim-width compatibility within that size.
205/75R15 is a modern metric radial size in which 205 identifies the nominal section width in millimeters, 75 is the aspect ratio, R marks radial construction, and 15 is the wheel diameter in inches. On the 1982 Buick Riviera, it suits buyers who want a more contemporary sizing format while staying with the correct 15-inch rim diameter. Available choices include BFGoodrich, American Classic, Coker Classic, Tornel, Maxxis, and Travelstar, with sidewall treatments such as narrow whitewall, wide whitewall, goldline, and redline. It is a useful fitment to evaluate when wheel width, sidewall appearance, and touring-oriented road use all matter.
GR70-15 is an alphanumeric radial size, where the lettered size class and 70-series profile reflect a vintage sizing convention and the 15 indicates a 15-inch rim. For the 1982 Buick Riviera, this format leans toward a more period-style presentation while retaining radial construction rather than bias-ply construction. Available options center on Goodyear products, including GM Custom Tread, Steelgard, and Custom Wide Tread designs, with sidewall treatments such as pin-white-stripe and raised white letter. This size is worth considering when the visual character of the tire is just as important as basic fitment.
Tire fitment is straightforward across the 1982 Buick Riviera range because the Base, Limited Edition, and T-Type all use the same two radial tire sizes. Checking the sub-model still helps, but the main decision is usually choosing between the metric and alphanumeric fitments and the appearance each one creates.

1982 Buick Riviera Base
The 1982 Buick Riviera Base uses the same 205/75R15 and GR70-15 radial fitments found across the covered Riviera lineup. Tire selection usually comes down to whether the car is staying with a modern metric whitewall-style radial or moving toward a more period-style alphanumeric presentation.
The 1982 Buick Riviera Limited Edition shares the same 15-inch radial fitment choices as the other covered sub-models, so size compatibility remains consistent. That makes sidewall treatment, tire series, and wheel-width suitability the more important comparison points when choosing a replacement set.
The 1982 Buick Riviera T-Type also uses 205/75R15 and GR70-15 radial tires, so the fitment story does not change by sub-model. The more meaningful choice is deciding whether the car should wear a cleaner modern metric radial or a stronger period-inspired alphanumeric radial 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.

Tire Size & Fitment
What tire size fits a 1982 Buick Riviera?
A 1982 Buick Riviera uses two primary tire sizes: 205/75R15 and GR70-15. Both are radial fitments and both use a 15-inch rim diameter, so the choice is not between radial and bias-ply, but between two different radial sizing formats and the tire styles available within each one.
That means the next step is confirming which size matches the wheel setup and overall look of the car. A metric 205/75R15 opens the door to several whitewall, redline, and goldline choices, while GR70-15 points toward a more period-style alphanumeric presentation with specialty sidewall treatments.
What size rim does a 1982 Buick Riviera use?
The 1982 Buick Riviera uses a 15-inch rim diameter with both of its primary tire sizes. That applies whether the car is equipped with 205/75R15 or GR70-15 tires, so wheel diameter remains consistent even though the tire sizing format changes.
Wheel width still needs to be checked before choosing among available tires. Some 205/75R15 products are suited to narrower wheel widths than the GR70-15 options, so a buyer comparing styles should verify the actual wheel dimensions on the car rather than relying on rim diameter alone.
Do all 1982 Buick Riviera sub-models use the same tire size?
Yes. The 1982 Buick Riviera Base, Limited Edition, and T-Type all use the same two tire sizes: 205/75R15 and GR70-15. Both are radial fitments on 15-inch rims, so there is no size split among the covered sub-models.
That simplifies shopping because the sub-model does not force a different tire size decision. Instead, selection usually comes down to the appearance and wheel-width requirements of the tires under consideration, especially when choosing between a modern metric radial look and a vintage-style alphanumeric radial look.
Choosing the Right Tire
What should I consider when choosing a 205/75R15 or GR70-15 tire for a 1982 Buick Riviera?
Start with the correct primary size for the wheel setup already on the car, then compare construction style, sidewall treatment, and rim-width compatibility. On a 1982 Buick Riviera, both 205/75R15 and GR70-15 are radial fitments, but they present the car very differently and can suit different wheel widths.
A buyer focused on a traditional luxury-coupe look may lean toward whitewall or pin-stripe styling, while someone chasing a stronger early-1980s visual theme may prefer raised white letters or an alphanumeric sidewall format. Wheel width, tire series, and intended use should guide the final decision more than appearance alone.
What sidewall styles are available for 1982 Buick Riviera tires?
The 1982 Buick Riviera has a wide sidewall spread depending on tire size. In 205/75R15, available styles include wide whitewall, narrow whitewall, goldline, and redline. In GR70-15, available sidewall treatments include pin-white-stripe and RWL, which is a raised white letter presentation.
That variety makes sidewall selection one of the biggest visual decisions on this car. A whitewall can reinforce the Riviera’s formal personal-luxury character, while goldline, redline, or raised white letters create a different period flavor. The best approach is matching sidewall style to the wheel design and the car’s overall restoration direction.
What brands offer tires for the 1982 Buick Riviera?
Brand choice depends on tire size. In 205/75R15, options include BFGoodrich, American Classic, Coker Classic, Tornel, Maxxis, and Travelstar. In GR70-15, the available products are Goodyear offerings across series such as GM Custom Tread, Steelgard, and Custom Wide Tread.
That makes the decision less about chasing one name and more about selecting the size and visual character that suit the car. A metric radial buyer has broader brand and sidewall variety, while a GR70-15 buyer is choosing within a more specialized Goodyear-style presentation on a 15-inch wheel.
Restoration & Appearance
Which tire should I choose for a period-style 1982 Buick Riviera?
A period-style 1982 Buick Riviera can go in two visual directions. GR70-15 carries a vintage alphanumeric radial format that looks closer to what many buyers expect to see on an early-1980s personal luxury coupe, while 205/75R15 offers a modern metric radial format with several traditional whitewall and specialty sidewall choices.
The better choice depends on how the car is being presented. If originality details matter, compare the tire look against vehicle-specific photos, literature, and marque references. If the goal is simply a believable period impression, sidewall treatment and overall visual proportion usually matter as much as the size format itself.
How does tire construction affect the appearance of a restored 1982 Buick Riviera?
On the 1982 Buick Riviera, construction changes the look less dramatically than on older cars because both primary fitments are radial. The bigger appearance difference comes from the sizing convention and sidewall treatment, with 205/75R15 looking more modern in format and GR70-15 delivering a more vintage alphanumeric presentation.
Sidewall details then shape the finished result. Wide whitewalls can emphasize the Riviera’s formal luxury personality, while pin-white-stripe or raised white letters shift the car toward a sportier early-1980s feel. Matching the tire look to wheel style and trim presentation will usually produce a more convincing restored appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1982 Buick Riviera?
Yes. Even though the 1982 Buick Riviera uses 15-inch tire fitments, modifications can still affect which tire works on the car. Aftermarket wheels, non-stock wheel widths, suspension changes, or body alterations can all change the amount of space available for a given tire size and sidewall profile.
A Riviera that still carries factory-style wheels may accept the intended fitment more predictably than one with later custom parts. Measuring the actual wheel width and checking steering, fender, and suspension clearance before selecting between 205/75R15 and GR70-15 helps avoid appearance mismatches and rubbing issues.
What should I inspect before driving a 1982 Buick Riviera on new tires?
Before putting a 1982 Buick Riviera back on the road, inspect wheel condition, lug hardware, valve stems, and inflation pressure, then look over the suspension and steering for looseness or wear. It also helps to confirm that the tires match the wheel diameter and that there is adequate clearance at full steering travel.
A collector-era car can develop problems even when it has not been driven much. Dry cracking on older tires, flat-spotting from storage, and aged rubber components elsewhere in the chassis can all affect how the car feels on fresh tires. A careful short test drive is a smart final check.
How should 205/75R15 or GR70-15 tires on a collector 1982 Buick Riviera be maintained?
Collector-car tires on a 1982 Buick Riviera should be kept properly inflated, inspected regularly for sidewall cracking, cuts, bulges, uneven wear, and slow air loss, and protected from long periods of harsh storage conditions. That applies whether the car runs 205/75R15 tires or GR70-15 tires on its 15-inch wheels.
Low annual mileage does not eliminate tire aging, so condition matters as much as tread depth. Parking on clean, dry surfaces, limiting exposure to prolonged sunlight and ozone sources, and moving the car occasionally can help preserve the tires. Any change in vibration, pull, or visible wear deserves prompt attention.
