The 1984 Buick Riviera came from an era when personal luxury coupes balanced crisp 1980s styling with comfort-minded road manners, and tire choice plays a big role in preserving that character. For this exact Riviera, the primary fitment centers on 15-inch radial tires in either 205/75R15 or 225/70R15. That gives owners a meaningful choice not just in size, but in sidewall presentation as well, including whitewall, redline, blackwall, and raised white letter options across several tire series. The real task is confirming which 15-inch setup is on the car now and choosing a tire that suits the Riviera's appearance, wheel width, and intended use.
Which Tire Size Is Right for The 1984 Buick Riviera
The 1984 Buick Riviera uses two primary tire sizes, and both are radial designs for 15-inch wheels. Because the same two sizes appear across the Base, Luxury, and T-Type sub-models, the first step is confirming which wheel and tire setup is actually on the car now. From there, the decision shifts to sidewall style, tire series, rim-width compatibility, and the kind of period look or driving presentation you want.
A 205/75R15 is a metric radial tire with a 205-millimeter nominal section width, a 75-series profile, and a fitment for a 15-inch rim. On a 1984 Buick Riviera, it represents a traditional full-profile radial look and keeps the selection focused on standard 15-inch wheel fitment. Available choices include BFGoodrich, American Classic, Coker Classic, Tornel, Maxxis, and Travelstar, with sidewall treatments ranging from narrow and wide whitewalls to goldline and redline styles. This size is worth considering when the car already wears the narrower setup and you want broad flexibility in appearance-oriented tire choices.
A 225/70R15 is a metric radial tire with a 225-millimeter nominal section width, a 70-series profile, and a 15-inch rim diameter. For the 1984 Buick Riviera, it stays within the same wheel diameter while offering a different metric sizing approach than 205/75R15. Product choices in this size include Goodyear, Cooper, Michelin, Maxxis, and BFGoodrich, with blackwall, narrow whitewall, wide whitewall, pin-white-stripe, redline, and raised white letter options available. This size deserves a close look when the Riviera has the wider tire setup and sidewall style is an important part of the finished appearance.
Tire fitment is straightforward across the covered 1984 Buick Riviera sub-models because Base, Luxury, and T-Type all use the same two radial tire sizes. The key is not identifying a different trim-specific size, but confirming which 15-inch wheel and tire combination is already on the car.

1984 Buick Riviera Base
The 1984 Buick Riviera Base shares the same two 15-inch radial tire sizes used elsewhere in the Riviera lineup. That means tire selection comes down to verifying the wheel setup on the car and then choosing the sidewall style, brand, and tire series that match its road use and appearance goals.
The 1984 Buick Riviera Luxury uses the same pair of 15-inch radial fitments as the other covered sub-models. Once the current wheel and tire size are confirmed, the main choice becomes whether to emphasize a formal whitewall presentation, a sportier sidewall treatment, or a particular tire series within the correct size.
The 1984 Buick Riviera T-Type also uses the same two primary 15-inch radial sizes found on the Base and Luxury models. The practical selection step is confirming which size is mounted now, then comparing options such as raised white letter, redline, blackwall, or whitewall designs within that exact fitment.
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 1984 Buick Riviera tire questions usually center on the two 15-inch radial sizes, how they relate across sub-models, and how to choose the right sidewall style and product type for restoration-minded or regular road use.
Tire Size & Fitment
What tire size fits a 1984 Buick Riviera?
A 1984 Buick Riviera uses one of two primary radial tire sizes: 205/75R15 or 225/70R15. Both sizes fit 15-inch wheels, and both appear across the Base, Luxury, and T-Type versions of the Riviera rather than being limited to a single sub-model.
The important step is checking which size is already mounted on the car and confirming the wheel dimensions before choosing replacements. Since both sizes were used on this Riviera, tire selection should follow the actual wheel and tire setup on the vehicle, especially if it has been changed over the years.
What size rim does a 1984 Buick Riviera use?
The 1984 Buick Riviera uses a 15-inch rim diameter with both of its primary tire sizes, 205/75R15 and 225/70R15. That shared rim diameter makes the basic wheel size straightforward even though two different tire sizes are associated with the car.
Rim diameter is only part of the fitment picture, so wheel width still matters when comparing actual tire choices. Product specifications in these sizes show different acceptable rim-width ranges, so it is smart to confirm the wheel width on the car before moving between tire models or between the two primary Riviera sizes.
Do all 1984 Buick Riviera sub-models use the same tire size?
The Base, Luxury, and T-Type versions of the 1984 Buick Riviera all share the same two primary tire sizes: 205/75R15 and 225/70R15. In other words, sub-model alone does not force a single unique size the way it does on some other vehicles.
That means the buying decision depends more on the actual wheel-and-tire setup on the car than on the trim name. A Riviera that has changed wheels over time, or one that has been restored or modified, should be checked carefully so the replacement tire matches the wheel width, diameter, and available clearance.
Choosing the Right Tire
What should I consider when choosing a 1984 Buick Riviera tire?
Start with the correct primary size on the car, either 205/75R15 or 225/70R15, and confirm that the wheel is a 15-inch setup. From there, compare sidewall style, tire series, brand, and rim-width requirements so the tire matches both the Riviera's wheel dimensions and the look you want.
A formal personal luxury coupe can take on a very different appearance depending on whether it wears a wide whitewall, narrow whitewall, redline, blackwall, or raised white letter tire. It also helps to compare load capacity figures and any wheel-width limits shown for a given product before settling on one option.
What sidewall styles are available for 1984 Buick Riviera tires?
Sidewall choices for the 1984 Buick Riviera are broad and include wide whitewall, narrow whitewall, redline, goldline, blackwall, pin-white-stripe, and RWL raised white letter styles. The available style depends on whether the car uses 205/75R15 or 225/70R15 and which tire series you are considering.
That variety makes sidewall design one of the biggest visual decisions on this Riviera. A whitewall can support a more formal luxury presentation, while redline or raised white letter tires create a sportier period look. Choosing the appearance first, then narrowing by the correct size and wheel compatibility, usually makes comparison easier.
What brands offer tires for the 1984 Buick Riviera?
Brands available in 1984 Buick Riviera tire sizes include BFGoodrich, Goodyear, Cooper, Michelin, American Classic, Coker Classic, Maxxis, Tornel, and Travelstar. Brand availability varies by size, so the exact mix of choices changes between 205/75R15 and 225/70R15.
Brand alone should not drive the decision. It is more useful to compare which size each brand offers, what sidewall treatments are available, and whether the tire's rim-width range suits the wheels on the car. Looking at the full combination of size, series, and appearance usually leads to a better match than choosing by brand name first.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Buick Riviera?
A period-style choice for a 1984 Buick Riviera starts with the correct primary size already on the car, either 205/75R15 or 225/70R15, followed by a sidewall treatment that suits the way the car is being presented. Whitewall, redline, blackwall, and raised white letter options all exist within the Riviera's fitment range.
The right visual direction depends on whether the car is being preserved as a formal luxury coupe, given a more personalized 1980s look, or restored with close attention to era-appropriate presentation. When exact originality matters, comparing the car against marque references, surviving examples, or factory literature is a smart next step.
How does tire construction affect the appearance of a restored 1984 Buick Riviera?
On a 1984 Buick Riviera, construction does not create a bias-ply versus radial decision because the primary fitments are radial. The appearance difference comes more from the tire's profile and sidewall treatment than from switching between construction types.
That makes details like wide whitewall versus narrow whitewall, redline versus blackwall, or raised white letter versus a cleaner sidewall especially important on a restored car. A tire can be restoration-oriented in look without being claimed as factory-correct, so the final choice should reflect both the car's style and the owner's goals.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Buick Riviera?
Yes, modifications can affect tire fitment on a 1984 Buick Riviera even when the tire size itself is one of the correct primary options. Aftermarket wheels, changes in wheel width, altered offset, suspension work, or body changes can all influence how a 205/75R15 or 225/70R15 tire sits and clears.
A Riviera that has been lowered, fitted with non-stock wheels, or rebuilt with different suspension parts should be checked at full steering travel and under normal loaded ride height. Measuring the actual wheel dimensions and inspecting fender and suspension clearance can prevent choosing a tire that is right on paper but awkward on the car.
What should I inspect before driving a 1984 Buick Riviera on new tires?
Before driving a 1984 Buick Riviera on new tires, inspect the wheels for damage, confirm the correct 15-inch diameter and suitable width, and make sure the tires are mounted in the proper size. It is also wise to check inflation pressure, valve stems, lug torque, and basic tread and sidewall condition.
A collector-era coupe can hide age-related issues that are not obvious at a glance, especially if the car has spent long periods parked. Looking over suspension wear, steering response, brake condition, and any signs of rubbing during low-speed movement helps confirm that the new tires are working with the rest of the car safely.
How should tires on a collector 1984 Buick Riviera be maintained?
Tires on a collector 1984 Buick Riviera should be checked regularly for pressure loss, cracking, bulges, cuts, uneven wear, and signs of flat-spotting from long storage. Even when the car is driven sparingly, the tires still need routine inspection because age and storage conditions matter as much as mileage.
Keeping the Riviera in a clean, dry space away from prolonged sunlight and ozone sources can help preserve the tires between drives. It also helps to move the car periodically, maintain proper inflation, and recheck the tires before longer outings so small issues are caught before they affect ride quality or road manners.
